[nysbirds-l] LI Birds: CC Sparrow, Dickcissel+

2009-10-01 Thread Shaibal Mitra
There was a nice flight along Long Island's barrier beaches this morning.

Highlights of an hour or so of birding on my way to work were Clay-colored 
Sparrow at Robert Moses SP plus Dickcissel and Lincoln's Sparrow at Cedar Beach 
Marina.

Moving heavily were Yellow-shafted Flickers, Eastern Phoebes, Myrtle Warblers, 
Chipping and Savannah Sparrows, and Indigo Buntings.

[nysbirds-l] LI Birds: Large Numbers of Common Eiders++

2009-11-01 Thread Shaibal Mitra
Common Eiders are occurring in unprecedented numbers around Fire Island Inlet, 
western Suffolk County. A tally of 390 at Robert Moses SP today far exceeded 
anything in my experience here. Also present along the barrier beach ocean 
front were thousands of Black Scoters, hundreds of Surf Scoters, and growing 
numbers of other waterfowl, including some oddballs, such as a pair of Lesser 
Scaup diving among scoters and eiders. Two Northern Shovelers, two Ruddy Ducks, 
and three Pied-billed Grebes in a freshwater pond near Fire Island Inlet were 
also locally unusual on the barrier beach. At Jones Beach State Park Field 6, 
the massive flocks of Dunlin, Black-bellied Plovers and Red Knots included 
three Western Sandpipers and a juvenile Golden-Plover. The latter sounded very 
odd to me during at least three bouts of calling, but we were never able to 
study it closely on the ground (it certainly wasn't a Euro). Royal Terns seem 
to be the default late season tern on LI nowadays--there were 52 at West End 
this morning, plus two more at Fire Island (Joe Vigliotta counted 73 at West 
End yesterday). Five Snow Buntings were picked out by Andrew Baksh at Robert 
Moses SP, Field 5.

Hi everyone,

Regarding Bob's and Angus' queries about the identities of the Pink-footed
and Barnacle Geese present now at Sunken Meadow SP, my own feeling is that t
he Barnacle is likely the same bird that wintered at Sunken Meadow SP in Jan
uary 2008 (two winters ago, and that the Pink-footed is possibly the same bi
rd that wintered at Stony Brook Mill Pond in February 2008. Both of those bi
rds were clearly distinct from their conspecifics in Montauk that winter, as
 proven by sustained periods of concurrent observations at these widely sepa
rated sites. My reason for feeling that the Sunken Meadow Pink-foot might be
 the same as the Stony Brook bird is not based on any careful studies of pho
tos, but the proximity of the two sites on the north shore of western Suffol
k County is suggestive. Also, both birds struck me as being relatively large
 for PFGO, whereas the Montauk bird seemed more petite.

Sorry for this late post. Yesterday afternoon, somewhere between 3 4 PM, I
 arrived at the eastern parking lots, to find 3/4's of the birding McBrien 
Family present, and the birds absent. Mom, Barbara, along with son, Michael,

Well they did/did and I got to see the above. While looking at the geese, i

Thinking back to the last time I saw these species together in Montauk, I c

Re: [nysbirds-l] Cattle Egret at Floyd Bennett

2009-11-20 Thread Shaibal Mitra
Hi Rob and all,

That's a really neat find, and in my mind, it's a good indication that
other oddities are likely lurking in the weeds around here.

As Cattle Egrets have vanished as breeding birds in NYS and New England,
November has become a relatively good time for seeing them here. The species has
lingered into mid December at least twice on eastern LI, including one at
Deep Hollow on the Montauk CBC, on 21 Dec 1996.

When two Cattle Egrets popped up near Mecox Bay on 17 November 2007, I
remember dashing off a note to Hugh McGuinness, volunteering a cockamamie 
theory of
correlated vagrancy of November Grasshopper Sparrows with Cattle Egrets
(based on a personal sample size of maybe two!). Although the
Grassgroper Hypothesis remains in limbo, chasing down those Cattle Egrets
the next day and later certainly revealed how rich and unexpected November
birding can be (Patagonia Picnic in Montauk Kingbird 58: 2-12).

Last year, there was a Cattle Egret at Fresh Kills, Staten Island in November, 
and one appeared at Mecox again, persisting into December, up to the eve of the 
Sagaponack CBC.

move a short distance when a loud motorcycle blasted down the road. Here's

[nysbirds-l] FW: Origins of Winter Vagrants--Research and a Chance to Help

2009-12-13 Thread Shaibal Mitra
As discussed in recent posts by Tom Fiore, Angus Wilson, and others, early 
December can be an exciting time for finding unusual birds in the Northeast, 
and the upcoming CBC season is sure to feature many exciting discoveries.

The question of where our early winter avian novelties come from is surely 
fascinating. As long ago as the 1950s, Ludlow Griscom showed that a winter 
specimen of Yellow-breasted Chat from Massachusetts was actually an example of 
the western North American “Long-tailed” Chat (Icteria virens auricollis), not 
the nominate southeastern subspecies that is rare as a breeder even on Long 
Island. This is really neat when one considers that, although the vast majority 
of Chats winter deep in the tropics, a significant—and increasing—number are 
now wintering from Long Island to Nova Scotia. Thus, this question of 
connections between breeding origins and winter occurrences has been taken up 
by researchers investigating topics as disparate as how bird populations are 
responding to climate change and how vagrancy fits into the migratory ecology 
of birds.

Juliette Goulet, a doctoral student at the College of Staten Island and the 
City University of New York, is studying some of these questions, using Gray 
Catbirds as a model. Unlike Chats, Summer Tanagers, and Rufous Hummingbirds, 
this species is a common breeder throughout New York State. Juliette would like 
to know if the increasing numbers of wintering catbirds in our region derive 
from local breeding populations, a variety of different breeding populations, 
or some specific breeding population other than our local one. It is possible 
that birds breeding, for instance, in the Upper Midwest, are colonizing a new 
wintering range in our region in response to environmental changes.

One part of Juliette’s dissertation research involves using stable isotope 
analysis to determine the breeding origins of catbirds wintering in the 
Northeast.

Anyone interested in these matters could greatly assist her in the following 
ways:

1. If you find a road-killed, window-killed, or cat-presented catbird between 
late November and early April, please contact either Juliette or me immediately 
so that we can arrange to salvage one to three tail feathers for analysis.

2. If you find catbirds wintering in places where banding is feasible, likewise 
notify us so that we might arrange to band the birds. By doing so, Juliette 
will be able to collect information concerning age and body weight, and also to 
collect a feather for isotopic analysis.

We hold permits to band birds and collect feathers from the federal, NYS, and 
other regional state governments. If in doubt, please contact us!

RE: [nysbirds-l] Fw: Southampton Black Guillemot Photo

2009-12-22 Thread Shaibal Mitra
Pat Lindsay also saw this bird this afternoon.

Given that this is a juv, the bird's extremely pale overall appearance is 
beyond anything I've ever seen in the usual Black Guillemots we see in Mass,  
RI, and LI (race atlantis).

The bird also shows a very petite bill. I wonder whether this individual 
represents one of the arctic-breeding races (ultimus, arcticus, or mandtii), 
none of which, I believe, has previously been documented in the state.

[nysbirds-l] Black Guillemot Subspecies

2009-12-24 Thread Shaibal Mitra
I spent some time this morning looking over references.

“The Birds of the Western Palearctic” (Volume IV, 208-219) gives lots of detail 
on geographical variation in Black Guillemots. According to this work (pp. 
218-219), white tips to the secondaries are absent in races other than the 
northernmost breeders mandtii and ultimus. This reference lumps ultimus, of 
high arctic North America and northwest Greenland, with mandtii, which breeds 
through Labrador, northern newfoundland, both coasts of Greenland, Jan Mayen, 
Svalbard, Wrangel Island, and Alaska).

It also corroborates the trend toward shortest bills and whitest juvenal and 
non-breeding plumages among arctic breeders, reaching an extreme in ultimus.

Sibley’s Arctic birds are depictions of the “mandtii group,” presumably 
inclusive of ultimus.

http://www.sibleyguides.com/about/the-sibley-guide-to-birds/subspecies-names-in-the-sibley-guide-to-birds/

Sibley depicts the white secondary tips of the Arctic juvs but doesn't make it 
completely clear that Atlantic juvs lack them.

For one more bit of the puzzle, I’ve posted a video grab of the Southampton 
bird’s underwing pattern in comparison to underwing of an adult 
atlantis/arcticus from Massachusetts:

http://picasaweb.google.com/tixbirdz/Various2009#

The Southampton bird matches BWP’s verbal descriptions of mandtii (or even 
ultimus), and Sibley’s depictions of the mandtii group, very well indeed.

The fifth edition of the AOU Check-list assigns the birds that typically occur 
in our region to the subspecies atlantis, and Sibley names the “atlantis 
group,” presumably inclusive of arcticus, as the model for the darker forms he 
illustrates.

Regarding the local situation on Long Island and southern New England, I can’t 
find any indication that people have proposed that mandtii or ultimus have 
occurred here previously. Instead, the various discussions of subspecies 
involve debates over whether the southernmost birds (atlantis) are consistently 
diagnosable with respect to the widespread arcticus (southern Greenland, 
Britain, and Scandinavia), or even with respect to nominate grylle of the 
Baltic Sea. For instance, Bull (1964  1974) regarded atlantis as poorly 
differentiated from arcticus, and Ken Parkes, in his doctoral dissertation, 
explained that the main feature distinguishing atlantis from grylle was wing 
length, with considerable overlap (pp. 253-255).

To sum up, it seems that the high arctic breeders (mandtii and ultimus) are 
very different from more southerly breeders (atlantis, islandicus (Iceland), 
faeroeensis (Faeroes), and grylle); and that the widespread catch-all arcticus 
(southern Newfoundland, southern Greenland, Britain, Scandinavia) is somewhat 
intermediate between the two groups, but decidedly closer to the darker, 
longer-billed southern breeders.

RE: [nysbirds-l] Mew Gull Description

Although I only deduced his name later, I'm sure Vincent was the fellow who 
notified several of us that the Common Mew Gull was present on the rocks near 
the pedestrian bridge around 3:30.

We walked north and found the bird right where Vincent told us it would be. We 
studied it briefly there and then at greater length a couple of hundred yards 
to the south, after we inadvertently spooked its flock.

This was an adult, as indicated by the immaculate tail, primaries with bold 
white mirrors and tips, and absence of black on the bill. Furthermore, details 
of the shape and color pattern of its bill, the pattern of its wingtips (e.g., 
the extensive black on p8 and the distinctive way that the lightly marked tip 
of p5 lined up with p6 on the folded wing), its relatively pale mantle tone 
(barely darker than that of Ring-billed Gull), and its small overall size leave 
no doubt that this was the same adult Common Mew Gull that has been present 
at this site since Shane found it.

[nysbirds-l] Long Island CBCs: Southern Nassau County and Captree

2010-01-04 Thread Shaibal Mitra
Hi everyone,

The Southern Nassau County Christmas Bird Count was conducted on Saturday, 2 
January 2010, by 49+ participants. This represents the 70th time this CBC has 
been held since its inception in 1932 (there were several years with no count 
during the 1930s and 1940s). References to “recent” maxima, minima, and 
averages below refer to the last 20 years.

In all, 121 species were recorded (plus two additional distinctive subspecies), 
a total well below the recent average of 128 species. Brisk northwesterly winds 
and snow showers impeded detection, and many participants expressed the 
perception that landbird densities have been generally low around Long Island 
this season (e.g., even on counts held under better conditions). The weather 
was even worse for the nearby Captree CBC on Sunday, and the notation “see 
NYCA” indicates some of the many instances of congruence between the two counts.

Among the many highlights were:
the count’s second ever “Richardson’s” Cackling Goose, in Baldwin (see NYCA);
the fifth ever occurrence of Tundra Swan, with two in Massapequa and one in 
Five Towns (see NYCA);
“Eurasian” Green-winged Teal in Baldwin (the 14th NYSN CBC featuring this 
taxon);
47 Ring-necked Ducks, all in Massapequa, a new recent maximum;
254 Common Eiders along the ocean front, shattering the previous max of 115 
from 2006;
90 Common Mergansers in five territories,for a new recent maximum (see NYCA);
178 Double-crested Cormorants, exceeding the previous max of 98 from 2001;
a new max of 23 Peregrine Falcons, spread across all nine territories, with 
duplications avoided as carefully as possible;
Tricolored Heron, by the Loop party;
2 American Bitterns at Tobay, plus one at Jones Beach;
Long-billed Dowitcher in Five Towns;
Iceland Gull at Jones Beach;
Lesser Black-backed Gull at Hempstead;
Razorbills at Jones Beach and Pt Lookou;
a recent max of 5 Eastern Screech-Owls;
1045 American Robins, exceeding the previous max of 757, from just two years 
ago;
an Orange-crowned Warbler at Tobay
the count’s third ever Pine Warbler, at Jones Beach;
four Saltmarsh Sparrows at Massapequa;
264 Common Grackles, obliterating the previous max of 80, from way back in Dec 
1958;
a Baltimore Oriole at John and Muriel Stahl’s feeders in Baldwin
and a recent max of 1073 House Sparrows.

Poor results were obtained for the following species:
Wood Duck was missed for the fifth time in 20 years;
Canvasback was missed for the third time in 20 years;
1 Ring-necked Pheasant was a recent minimum;
Great Egret was missed for the fourth time in 20 years;
American Kestrel was missed for the fourth time in 20 years (see NYCA);
Short-eared Owl was missed for the fifth time in 20 years;
30 Blue Jays (see NYCA)
Fish Crow was missed for the first time in 20 years (see NYCA);
1 Eastern Towhee was a recent minimum (see NYCA);
and 1 Field Sparrow was a recent minimum (see NYCA).

Obviously, we also missed a large number of the “toss-up” species that we 
expect to find in 33-67% of years.

Species recorded during the count week, of which I am aware at present, include:
Willet, Great Horned Owl, Chipping Sparrow, and Rusty Blackbird



The Captree Christmas Bird Count (circle just east of Southern Nassau County's) 
was conducted on Sunday, 3 January, 2010, by 30+ participants. This represents 
the 48th consecutive year this count has been held since its inception in 1962.

In all, 109 species were recorded (plus one additional distinctive subspecies), 
a total well below the count’s 20-year average of 116 species. The count was 
rescheduled from 20 Dec because of a blizzard that dumped two feet of snow, but 
the weather yesterday was also appalling: average wind speeds of 24 mph (max 
gusts of 48 mph), a high temperature of 22 F, and frequent snow squalls. Given 
the circumstances, I think the results were quite impressive.

Highlights included:

7 Greater White-fronted Geese at Belmont
1 Cackling Goose at Belmont
1 Tundra Swan at Connetquot
8 Wood Ducks at Belmont
1 Eurasian Wigeon in the Babylon-West Islip area
3 Common Eider on the ocean front
116 Common Mergansers, obliterating the previous max of 22, from 1995 (a 
consequence of rescheduling the count two weeks later)
2 Virginia Rails in the West Sayville area
1 Killdeer in Bay Shore
1 Iceland Gull in the Babylon-West Islip area
1 Lesser Black-backed Gull in Bay Shore
1 Great Horned Owl by the North party
12 Tree Swallows in the Oak Beach-Cedar Beach area
29 American Pipits
1 Pine Warbler at Connetquot
2 Chipping Sparrows at Heckscher

Poor results were recorded for the following species:

3 Canvasback
55 Greater Scaup (often thousands in Great South Bay)
0 American Kestrel
19 Blue Jay
0 Fish Crow (306 last year!)
28 Carolina Wren
2 Gray Catbird
3 Eastern Towhee
3 Field Sparrow
0 Brown-headed Cowbird

Species recorded during the count week, of which I am aware at present, include:

Monk Parakeet, Fish Crow, Lapland Longspur, and Rusty Blackbird

RE:[nysbirds-l] Long Island CBCs: Southern Nassau County and Captree

2010-01-05 Thread Shaibal Mitra
I'd like to mention that full data for these counts, including effort, weather, 
and participants' names, will be published in the June 2010 issue of The 
Kingbird, the journal of the New York State Ornithological Association--and 
I'd like to invite the compilers of other counts in NYS to contribute their 
data for publication as well.

If you haven't done this before, please don't hesitate to contact me regarding 
how to format your data.

There are several major advantages to publishing NYS CBC data in The Kingbird 
in addition to uploading data online to the National Audubon Society site.

1. The data published in The Kingbird clearly specify the species and 
subspecies reported, using uniform conventions across all the counts in NYS.

In contrast, the online database collects and presents data under a bewildering 
variety of partially overlapping names. This problem is not a mere 
inconvenience; it is an almost intractable obstacle to simple data analysis.  
For instance, if one wanted to quantify something as simple as the rise and 
fall of wintering numbers of Great Black-backed Gull on Long Island during the 
last century, one wouldn’t find this name in the database at all until some 
time after Lesser Black-backed Gulls began appearing in North America, at which 
point compilers began reporting the common species under its full English name. 
 Records from earlier years would have to be deliberately retrieved under 
‘black-backed gull species’ and then integrated in the analysis by brute force. 
 Even worse, some birds continue to be reported under different names from year 
to year, even on the same count.  For instance, one of Long Island’s most 
numerous waterfowl, Brant (Branta bernicla), appears in the database under no 
fewer than eight names. ‘Brant,’ ‘Brant (hrota),’ ‘Brant (nigricans),’ 
‘White-bellied Brant,’ ‘Black Brant,’ ‘American Brant,’ ‘Black Sea Brant,’ and 
‘Pacific Black Brant.’ A researcher wishing to analyze data for this species 
has no choice but to make separate queries for every one of these names, 
download the results of each query, and integrate the multiple data sets.  The 
last task is extremely difficult because some of the names in question are 
simple synonyms or refer to completely distinct taxa, whereas others (e.g., 
‘Brant’ and ‘Brant (hrota)’) overlap only in part.  These ambiguities were 
formerly easily resolved by recourse to the published data, in which nobody 
could mistake the continuity between the 20,000 ‘Brant’ reported on a count one 
year and the 17,000 ‘Brant (hrota)’ reported there the next year, or what was 
meant by 3 ‘Towhees’ on a New York CBC.  The tabular output currently available 
from the electronic database is another matter altogether, and even after 
laborious mining and reprocessing, many simple questions remain essentially 
impossible to answer.

2. The Kingbird strives to present full data for effort, weather, and 
participants' names--none of which can be obtained easily from the online 
database.

For instance, it is increasingly common for people to participate on a CBC as 
usual, but to decline to pay the $5 fee, forcing the compiler to omit these 
people's names (and in some cases, even any numerical trace of their effort!) 
from the data uploaded to the Audubon site.

3. Finally, one of the greatest pleasures of CBC participation comes from 
browsing through multiple counts of many kinds--rival counts for highest 
species lists, other counts held on the same glorious (or miserable) day as 
one's own count, counts that one used to attend in past years, or counts in 
which distant friends actively participate. Almost everyone I know laments the 
near impossibility of doing this via a series of carefully conceived, directed 
searches though the online database. In contrast, The Kingbird's CBC issue 
can be browsed as intensively or as casually as one wishes--and can be searched 
electronically also! (see: http://www.nybirds.org/KBsearch.htm)

Compilers frustrated with problems such as these have a recourse, through 
publication of their results in The Kingbird. Similarly, active CBC 
participants who are not compilers might consider offering to assist the 
compiler(s) of their favorite counts with the extra work associated with 
formatting the results for The Kingbird.

Finally, I'd like to correct three errors in the preliminary summaries posted 
last night for the Southern Nassau and Captree CBCs:

The species total for Captree was 110 (not 109, as stated).

Bob Grover's and Nick Laviola's Eurasian Wigeon was on Santapogue Creek, on the 
West Babylon-Lindenhurst line (not Babylon-West Islip, as stated).

Sy Schiff's and Joe Giunta's count-week Lapland Longspur was for Southern 
Nassau (not for Captree, as stated).

[nysbirds-l] Dovekie Ashore on Staten Island

2010-01-26 Thread Shaibal Mitra
Tom Brown and Juliette Goulet from College of Staten Island just called with 
news of a distressed Dovekie found ashore at Miller Filed, Staten 
Island--undoubtedly a victim of yesterday's storm.

A similar storm on 26-27 Dec drove a number of Dovekies ashore from 
southeastern New England to Long Island, so it would be worth checking the 
ocean shore today.

RE: [nysbirds-l] Brooklyn - Black Vulture

2010-02-09 Thread Shaibal Mitra
Hi everyone,

I would lean toward local movements, rather than northbound migration, as the 
mechanism behind most of the observations mentioned in this thread. Among 
freshwater ducks, facultative dispersal is often conspicuous throughout the 
winter on Long Island, where unfrozen salt water is almost always just a short 
flight away from the ponds preferred by the various species. On the weekend 
before last, Tom Burke and we were only slightly surprised to find that most of 
250 scaup out on Great South Bay were Lessers, rather than Greaters, which are 
usually the numerous species on the open salt bays. Nearby were many excellent 
Lesser Scaup ponds, which had recently re-frozen. Similarly, last weekend, Dick 
Veit and we were not very surprised that a lone scaup on the Atlantic Ocean 
near Shinnecock Inlet was a Lesser. When their preferred ponds freeze, even 
Common Mergansers will resort to the ocean at times 
(http://picasaweb.google.com/tixbirdz/Various2009#5420408466155755842).

Regarding vultures, I've seen winter roosts in southern New England still 
cohering as late as late March. The big spring vulture flights on Lake Ontario 
occur in early April, and even in Veracruz, Mexico, the peak flights occur in 
late March. As Steve notes, snow cover could be a factor influencing local 
movements for these species, as it clearly is for many raptors.

These things are on my mind because we are just about to do our Presidents Day 
Count out on Block Island, where we have been bracketing the CBC with similar 
effort in November and February since 1996--with the goal of disentangling 
dispersal, migration, and mortality as mechanisms underlying changes in bird 
abundance. A quick search through these data for species occurring in larger 
numbers in Feb than Dec reveals a hint of hard weather dispersal (slight 
upticks for a few freshwater ducks, raptors, and marginal winter species, such 
as Greater Yellowlegs. Only Red-winged Blackbird and Common Grackle are obvious 
northbound migrants (although a few scarcer species, notably Wood Duck, might 
also belong here rather than in the previous category). But the most obvious 
examples of species that consistently increase in abundance between Dec and Feb 
are Common Goldeneye, Oldsquaw, Horned and Red-necked Grebes, Great Cormorant, 
Common Murre, and Black Guillemot. Most of these species are scarce to absent 
in Nov, pick up a little bit in Dec, then increase markedly by Feb (Oldsquaw 
and Great Cormorant are the exceptions, being common in Nov, holding steady in 
Dec, then surging in Feb).

If you are a fan of the CBCs, it might be fun to spend a day next weekend 
covering your favorite territory the way you did in Dec.

Is this a migrant, already? is my question of the day, too. My subject was a 
Common Merganser on Oakland Lake, Queens, where the species only occurs as a 
spring migrant. But things could be shuffling around because of ice (Oakland 
Lake itself is two-thirds iced up (interestingly, a lone Lesser Scaup appeared 
there last week)) or snow. I've noted Rough-legged Hawks and other raptors 
coming our way in past years (around late January) after significant snowfalls 
to the north. It would be a strange twist if the vultures appearing to be 
headed north are evacuating the big snowfall that fell to our south.

I know Turkey Vultures start migrating in February, but it is still pretty 
early in the month, and Black Vultures aren't yet common in the area (they're 
still downright rare in Brooklyn, even in peak migration) so it came as quite a

There were also ~1600 Ring-billed Gulls (counted and examined closely),

[nysbirds-l] North NY Update 21 Feb--Ivory Gull Yes, Tufted Duck Yes, Hawk Owl No

2010-02-22 Thread Shaibal Mitra
The adult Ivory Gull found by Pat Jones on Friday, near the NY/VT/Canada border 
remained through the weekend. Having been seen by Bryan Pfeiffer and others at 
the usual spot near the Vermont side of the causeway early in on Sunday 
morning, the bird went unseen for a couple of hours until rediscovered at the 
end of Stony Pt Road by Patricia Lindsay and a gentleman whose name I didn't 
learn. It gave great looks at this site near Rouse's Pt., Clinton Co., NY 
throughout the late morning yesterday. A post this morning from Allan Strong on 
the Vermont site states: I just received a phone call Ben Griffith and Thomas 
Ford-Hutchinson that the Ivory Gull is being seen again today (Monday 2/22).  
It is being seen from the Vermont side of the Lake at the Rouse's Point Bridge. 
 The bird was fairly far south of the bridge, but clearly visible out on the 
ice.--so be sure to check multiple sites if the bird is elusive.

Patricia Lindsay, Pat Jones, and I were not able to find the previously 
reported Northern Hawk Owl in nearby Champlain, Clinton, Co., NY, despite 
considerable searching, but there were at least three Northern Shrikes present 
in the area.

The Tufted Duck found by Pat Jones during another one of his productive, 
non-chasing interludes remained in Valcour, Clinton Co., NY yesterday, giving 
great looks as it fed among five other species of Aythya , Common Goldeneyes, 
and Common Mergansers. The Tufted Duck seemed to asociate consistently with the 
smaller flocks of Lesser Scaup closer to shore rather than the huge rafts of 
Greater Scaup farther offshore, though some of the Greaters moved in close too 
from time to time. Also present were 36 Ring-necked Ducks and single drake 
Redhead and Canvasback.

RE: [nysbirds-l] Brooklyn BLVUs

2010-03-25 Thread Shaibal Mitra
Curiously, statewide trends and recent Long Island trends stand in remarkably 
different relationship for each of the big black carrion-eaters under 
discussion.

When Griscom analyzed the status of Turkey Vulture in 1923, this species was 
common in the highlands of northern New Jersey but poorly distributed in 
mainland NYS and a rare visitor to LI, with most LI records from the western 
(e.g., Brooklyn) or eastern (e.g., Orient) ends. Over the remaining eight 
decades of the 20th Century, this bird underwent a vast northward expansion, 
spreading across most of mainland NYS--but retaining its LI status (scarce and 
irregular) with astonishing fidelity. Few birds of any kind showed such a 
static pattern on LI over the same period--but for a bird whose status changes 
so much nearby, this stasis is particularly remarkable. It has only been over 
the last ten years or so that Turkey Vultures have finally moved onto LI in 
numbers, including winter roosts and proven breeding. The lag between 
occupation of the adjacent mainland and dramatically increased occurrence on LI 
in this case was 50 years.

The early history of Black Vulture in NYS was mostly as a vagrant to LI. Again, 
it's status on LI remained static for a century while the species made news 
elsewhere. In contrast to its relative, however, Black Vulture's northward 
expansion on the mainland lagged behind Turkey Vulture's by at least several 
decades, and its occupation of the Hudson Highlands and nearby parts of 
mainland NYS took place mainly in the 1980s and 1990s. This distinction is very 
important because Black Vulture's trend toward increased occurrence on LI, 
which prompted this thread, has occurred more or less simultaneously with 
Turkey Vulture's, in very recent years. The lag between occupation of the 
adjacent mainland and dramatically increased occurrence on LI in this case was 
about 15 years.

As Kevin notes, Raven was once almost extirpated from the eastern United States 
and was no more than scarce wilderness specialist in NYS for the first 
two-thirds of the 20th Century. Its expansion over the last several decades has 
been spectacular, e.g., a 500% increase in occupied blocks between the two 
atlases. Like both of the preceding species, Ravens have made news on LI during 
the last few years. Unlike them, however, this trend followed immediately upon 
its occupation of adjacent mainland areas, with no perceptible lag at all.

Another hulking black carrion-eater probably deservers mention here. Bald 
Eagle's inter-atlas surge in NYS makes Raven's seem downright paltry, its 
confirmed blocks increasing 6,000%! Statewide observers probably don't 
appreciate how oddly scarce this species remained on LI through most of the 
20th Century, even as its status was changing so radically in nearby mainland 
areas. Admittedly, the broader trends for this species are far more complex 
than those described above, with regional breeding populations, those breeding 
far to the north, and also wanderers from the south each experiencing its own 
roller-coaster fortunes and contributing to LI occurrence. Even so, one gets 
the impression from reading the books that Bald Eagle's LI status didn't vary 
greatly from Griscom's time (1923) to Cruickshank's (1942) to Bull's (1964) to 
the late 20th Century (personal experience), except that it was probably even 
scarcer here during and after the DDT era (60s-90's). Although I know this 
doesn't do justice to this species' comnplex history, I can say without doubt 
that there has been an abrupt increase in the occurrence of Bald Eagles on LI 
and in RI during the last ten years, as compared to the 80s and 90s.

Like all of the preceding, Fish Crow expanded as a breeder in NYS between the 
two atlases, but unlike any of the others, Fish Crow initially moved into 
southeastern NYS in an equitable fashion, occupying both the Hudson Valley and 
LI over a century ago. Given its ubiquity on LI throughout my own experience, 
I'm not sure if it has increased here very much over the past ten years, but my 
hunch is that it has increased at least somewhat. Fish Crow has expanded 
greatly in southern mainland RI over the last decade.

Last, and perhaps most important from an ecological point of view, is the case 
of American Crow. It is very difficult to quantify the status of this abundant 
and truly ubiquitous bird, but the impacts of West Nile Virus in the early 
years of the past decade have been much publicized. Even giving due allowance 
to the difficulties of counting crows owing to vagaries of their local 
movements and roosting patterns, I'm convinced that this species is much less 
numerous today than ten years ago in the areas I know best--LI and southern 
mainland Rhode Island. In these areas, at least three long-standing roosts of 
+10,000 birds simply seem to have vanished. Even if many of those birds have 
moved a few tens of miles away or shifted to a more dispersed distribution, the

The Upland Sandpiper continued at Robert Moses SP, Suffolk Co., LI through the 
day today and was seen by many observers. Apparently it was difficult to find 
at times, but it was still there at 18:35 when I swung through on my way home. 
I looked at the ocean briefly just before this and was pleased to see a Harbor 
Porpoise, two Red-necked Grebes flying westward, and several motley skeins of 
piebald, molting Oldsquaws, also flying westward. In contrast, the scoters, 
loons, and Gannets (whose recent morning movements have been overwhelmingly 
eastward) were mostly sitting on the water. Of interest was a feeding flock of 
ca. 60 Bonaparte's Gulls far out, near the limits of visibility.

This morning, on my way into work, I noted two new arrivals at Jones Beach West 
End: a Least Sandpiper and five Forster's Terns.

Relative to Hugh's report from East Hampton, I recall that Andrew Baksh found 
two Blue-winged Teal at Cow Meadow, Nassau County, on 1 April.

[nysbirds-l] Hudsonian Godwit Orange County, Sat-Sun

2010-04-12 Thread Shaibal Mitra
A breeding-plumaged Hudsonian Godwit was found at the Wallkill River NWR, 
Orange Co. on Saturday evening by members of the Mearns Bird Club, including 
Dennis Murphy.

It was found again on Sunday morning by Tom Burke, Gail Benson, and Andy 
Guthrie.

The bird fed along a muddy berm trending north-south within the impoundment 
immediately south of the parking area on Oil City Rd. It was visible from the 
dikes along the east and west edges of this impoundment, but views were very 
distant from the east side and compromised by poor light from the west side. An 
early Spotted Sandpiper was also present in this impoundment.

Late in the morning, the godwit was joined by three Lesser and one Greater 
Yellowlegs. They all crouched low as a Peregrine flew up from the south, then 
flushed when it returned a few minutes later. In flight, its black underwing 
coverts and black and white tail pattern left no doubt about its identity, but 
unfortunately the group continued flying southward, out of sight into New 
Jersey.

[nysbirds-l] LI Birds: Willets, Semi Plovers, RAZOs, Protho+

2010-04-17 Thread Shaibal Mitra
There was a heavy movement of waterbirds along LI's outer beaches this morning, 
with migrating Common Loons outnumbering Red-throated for the first time this 
spring--at least for me. Double-crested Cormorants were moving very heavily, 
totaling around 1,100 over the course of the morning. The most notable 
highlight of a short seawatch at Robert Moses SP, Suffolk County was a trio of 
Razorbills.

Shorebird arrivals at Jones Beach West End, Nassau County included two Willets 
and two very early Semipalmated Plovers. It's rather early for Willets too, so 
we gave them a close look. Based on their pale plumage tones, I initially 
considered the possibility of Western Willet--despite their full breeding 
plumage, something we seldom see among Western Willets on LI. Bill shape, 
however, indicates nominate Eastern Willet. A photo can be viewed at:

[nysbirds-l] LI Birds: Big Shorebird Push

2010-04-18 Thread Shaibal Mitra
Large numbers of shorebirds arrived today on the marsh islands north of Cedar 
Beach, Gilgo, and Tobay. The flocks were dominated by Dunlin (ca. 5,000) and 
Black-bellied Plover (ca. 500), but several unusual species were also present. 
Pat and I spread the word about the shorebirds after we found a basic-plumaged 
Red Knot and two Ruddy Turnstones at Cedar Beach Marina, around 9:00. A little 
later, we found two early Short-billed Dowitchers at Tobay (one was a yearling 
bird retaining a tiger striped, albeit heavily worn, juvenal tertial). 
Meanwhile, Tom Burke and Gail Benson arrived at Cedar Marina and picked out an 
American Golden-Plover and another dowitcher. We rejoined them in time to see 
the Golden-Plover, plus a breeding-plumaged Red Knot they found in the interim.

We saw immature male Common Eiders at Robert Moses SP and Jones Beach SP, an 
adult Yellow-crowned Night-Heron was present at Camman's Pond, and an 
Orange-crowned Warbler continued at Hempstead Lake SP.

[nysbirds-l] LI Birds: Shorebirds, Terns, Swallows++

2010-05-03 Thread Shaibal Mitra
A quick visit to Jones Beach West End today yielded the best diversity of 
shorebirds I've seen yet this spring:

120 Black-bellied Plovers (max yesterday 90 at Cupsogue)
1 Semipalmated Plover (max yesterday 4 at Cupsogue)
70 Red Knots--most in full breeding plumage
5 Ruddy Turnstones (max yesterday 9 on Dune Rd.)
90 Short-billed Dowitchers, including one hendersoni (three along Dune Rd. 
yesterday plus singles at Shinnecock and Cupsogue; and two at Goethals Bridge 
Pond on Saturday)
600 Dunlin (max yesterday 350 at Cupsogue)
15 Sanderlings (half in partial breeding plumage)
60 Least Sandpipers (max yesterday 60 at Cupsogue)
15 Semipalmated Sandpipers (my first of season)

There were at least 170 Common Terns at West End today (following 100 east of 
Triton Lane yesterday and my first seven of the season at Fire Island on 
Friday). These were with about 30 Forster's Terns and a pair of Gull-bills (my 
first was there on Friday evening), and we saw our first Least Tern at Jamaica 
Bay on Saturday. There was a first summer Lesser Black-backed Gull in the rain 
pool in front of Field 2, Jones Beach West End, today.

A striking aspect of the flights this weekend were the many blackbirds and 
swallows involved in westward migration. I thought the blackbirds were 
interesting because we don't often think about blackbird migration continuing 
this late in the season, but many Red-winged Blackbirds, Common Grackles, and 
Brown-headed Cowbirds were clearly migrating at places like Robert Moses SP, 
near the western tip of Fire Island, and we even saw a meadowlark (presumably 
Eastern) there yesterday (Eastern Meadowlarks were conspicuous on territory 
later yesterday at the Grumman grasslands). Barns Swallows were moving westward 
at Fire Island on Friday morning and again yesterday morning, when 71+ were 
joined by small numbers of Tree, Bank (2), Rough-winged (1), Purple Martin (2), 
and Chimney Swift (14). The swallow flight was stronger if anything along Dune 
Rd. in the afternoon, when we counted 176 migrating westward, along 2 more 
Banks and a my first Cliff Swallow of the season. Two other species that you 
might not expect would fly westward along the Long Island coast during spring, 
but which nevertheless consistently do this, were 4 Eastern Kingbirds and a 
Red-headed Woodpecker at RMSP yesterday (photo of the RHWO at: ).

Although this sort of reorientation behavior is typical of night-migrating 
Neotropical migrants such as warblers, tanagers, and orioles, of which there 
were a few along the beaches both Friday morning and yesterday, I'm trying to 
get used to seeing more Orchard Orioles than Baltimores almost everywhere on LI 
these days: between the two of us, Pat and I connected with Orchards at Staten 
Island, Babylon, Edgewood, Fire Island, Calverton, and Eastport this weekend.

Warbler highlights from the weekend included a Western Palm Warbler at Clove 
Lakes Park, Staten Island, on Friday morning (quite rare in southeastern NY 
during spring); Hooded and Cerulean there on Saturday morning; and a 
Worm-eating at Hunters Garden, central Suffolk County, yesterday. Somewhat 
early for central-eastern LI was a Red-eyed Vireo in Manorville yesterday, and 
very early in my experience was an Eastern Wood-Pewee at Clove Lakes on 
Saturday.

RE: [nysbirds-l] May 13th Western Race Fox Sparrow in Central Park

2010-05-13 Thread Shaibal Mitra
Dear Karen and all,

This report is extremely exciting and of great interest to many people. I would 
be most appreciative of any follow-up reports concerning whether the bird 
continues to be seen.

Please document this bird as carefully as possible. Paul Buckley recorded a Fox 
Sparrow of the subspecies altivagans at Fire Island Lighthouse on almost this 
date (12 May 71--note that these dates are a month later than Red Fox Sparrows 
are expected in southeastern NY). Collected as a specimen, that record has been 
much studied and debated over the years. This one deserves to be described in 
detail and photographed if possible.

Hi All,
Stephanie Seymour and Rob Fanning just called to report a Fox Sparrow
(Western Subspecies, a much grayer form) in Strawberry Fields in
Central Park.  The sparrow was found on the wood chip path by Steve
Chang and Andrew Rubenfeld about 15 min ago (~6:45am).  Good luck if

[nysbirds-l] Stellar Flight on Barrier Beach

2010-05-15 Thread Shaibal Mitra
Evidently, the passage of last night's cold front was such that many Neotrops 
were tempted a-flight by southwest winds early in the eve, drifted out over the 
New York Bight, then caught out when the winds turned northwest. Under these 
conditions, nocturnal migrants drop in as soon as they reach the beach, then 
bounce along from east to west through the morning.

This morning's flight at Robert Moses SP was probably the best I've seen there 
since the epic flight of 10 May 2002. Although much smaller than that flight, I 
counted approximately three warblers per second from 8:30-9:00. Pat had seen 
birds passing at a similar rate earlier in the morning, and birds continued 
passing at an impressive rate until 9:30.

For those not familiar with these re-orientation flights, it's worth noting 
that some species (e.g., flycatchers and thrushes) tend not to participate in 
the post-dawn westward bouncing, even though they might have come ashore in big 
numbers. As expected, I didn't connect with many of these birds as I monitored 
this morning's flight. I was surprised, however, at the poor showing made by 
some of the larger, stronger flyers (e.g., RB Grosbeak, Scarlet Tanager, 
Baltimore Oriole) that are often very numerous in these kinds of flights. 
Anyway, some highlights were:

5 Solitary Sandpipers--three singles and one pair, all flying westward
1 Black-billed Cuckoo
3 RT Hummingbirds
250 Chimney Swifts--by far my highest count ever from the barrier beach; all 
flying westward, as were all the swallows listed below
21 Eastern Kingbirds--all flying westward
1 Blue Jay--usually absent from the barrier beach
1 Purple Martin
1 Northern Rough-winged Swallow
8 Bank Swallows
9 Cliff Swallows
400 Barn Swallows
58 Cedar Waxwings
20 species of warblers, including 110 Magnolia, 70 BT Blue, and 33 Canada

I was able to identify only ca. 20% of the warblers that flew by--about 300 of 
the ca. 1,500 warblers I saw.

We wound up seeing 103 species between RMSP and Jones Beach, and our only 
woodpecker of the day was a Red-Headed that Pat saw at Jones Beach just before 
we quit!

[nysbirds-l] The Window Is Open!

2010-05-19 Thread Shaibal Mitra
A one-hour seawatch at Robert Moses SP (7:00-8:00) yielded a good flight of 
Common Loons, lots of milling Gannets, one White-winged Scoter, and one adult, 
light-morph Parasistic Jaeger heading east.

Although my search for Sooty Shearwater was not successful today, I was happy 
to get a call from Long Island transplant to Virginia, Andy Baldelli, who was 
of like mind down at Virginia Beach.

Andy found at least two, and probably three, adult Arctic Terns there today, as 
well as two Sooty Shearwaters.

No such luck on LI, but Roseate Terns continue around Fire Island Inlet, and 
the immature Blue Grosbeak was still patrolling the plantings near the entrance 
to Parking Field 2 at Robert Moses.

With Andy's permission, I posted several of his photos to:

[nysbirds-l] LI Birds: Arctic Tern+++

2010-05-23 Thread Shaibal Mitra
Inspired by Andy Baldelli's exploits down in Virginia, I visited Democrat Pt. 
(Fire Island Inlet) and Cupsogue (Moriches Inlet) today, in search of Arctic 
Terns--and found an adult at Cupsogue on the rising tide. Photos can be seen at:

http://picasaweb.google.com/tixbirdz/LongIslandMiscellany2010#

Earlier, at Democrat Pt., I saw my first Sooty Shearwater and Black Tern of the 
season, and counted 13 Roseate Terns resting among Common Terns (other Roseates 
were visible or audible over the inlet and ocean at all times, also. Only two 
of the 13 were banded. A young Lesser Black-backed Gull was also present.

A seawatch at Cupsogue with Patricia Lindsay, Tom Burke, and Gail Benson 
yielded about a dozen Sooty Shearwaters and at least one adult light morph 
Parasitic Jaeger.  There were decent numbers of shorebirds at Cupsogue, but I 
thought the numbers at nearby Pikes Beach were paltry for the date. A first 
summer Lesser Black-backed Gull was present at Pikes. Pat saw an Acadian 
Nelson's Sparrow among half a dozen Saltmarsh Sparrows and a few Seasides at 
Cupsogue.

Tom and Gail kept up the seawatching after we left, and at Shinnecock Inlet 
they saw a Manx Shearwater and a Little Gull, among other species. During an 
earlier stint at Shinnecock they had seen an immature Black-legged Kittiwake, 
and, earlier still, a young male Blue Grosbeak at the DEC bikepath along Rte. 
51 in Eastport, Suffolk County. They searched for but did not see the 
previously reported Wilson's Plover at Sagaponack.

RE: [nysbirds-l] Blockbusting/fixed link

2010-06-09 Thread Shaibal Mitra
Matt raised a very legitimate point about potential variability in mortality 
risks among sites, and he did so in a non-confrontational manner, not deserving 
of a sarcastic response.

Irony is a twin-edged sword, however, and it often rings oddly in a discussion 
like this. Seriously, who wouldn't love to see a thorough study made of the 
bird-life at the proposed site near Batavia?

The question of whether to place a particular for-profit industrial 
installation in a particular place is incredibly complex, and I doubt that 
Matthew meant to imply that the papers he cited constitute a carte blanche for 
the proposed Batavia project.

The density and species composition of birds varies not only among sites, but 
even at a particular site, where they can vary tremendously from season to 
season and from year to year (as students of migration can attest, via many, 
many scientific studies).

I was reminded of this quite forcefully earlier this spring as I watched 
literally thousands of Neotropical migrant landbirds struggle ashore at Fire 
Island, Long Island, in a classic spring fallout event. These birds passed 
through an airspace that has been debated as a wind farm site. The occurrence 
of these fallout events is a certainty over appropriate time-scales, but many 
regional wildlife biologists and active birders have never witnessed even one 
in their lives. These days you can't miss the interviews with scholars who 
study the great difficulty that cost-benefit analyses suffer in correctly 
evaluating the risks arising from these low probability/high magnitude events.

Why do comments like, the numbers of birds killed at turbines are in the

Hello all,

I fully agree that wind power can help us move towards a more sustainable
form of energy! However, there is a right and wrong place to do this. I'm not
necessarily saying that this project should not happen, but given its close
proximity to a fabulous upstate National Wildlife Refuge, I do not think that
two 3 minute point count surveys at 20 points is sufficient! Do we need a
$100,000 survey to make a determination, no, but given how sneakily things
can sometimes be done in this country, I do think doing a thorough survey is
warranted!

When I see comments like, the numbers of birds killed at turbines are in the
single digits per year per turbine, my suspicions get greater!! This stat
all depends on the _where_, especially since I strongly believe
inappropriately placed turbines can kill many more than a handful of birds!
Others that more closely work on this issue can certainly speak with greater
scope and surely can provide many papers that cite the mortality that can
sometimes happen at certain turbines.

cheers,
Matt

[nysbirds-l] LI Birds: Early Summer Shorebirds and Seabirds

2010-06-14 Thread Shaibal Mitra
Mid June presents some interesting and unexpected opportunities for birding on 
Long Island. An uptick in landbird vagrancy around the time of the solstice is 
a well recognized (if poorly understood) pattern nowadays, but who would 
surmise, by checking range maps or reading the old books, that Northern Gannets 
and Lesser Black-backed Gulls would be more numerous on LI in June than in 
January?

Bobby Berlingeri recorded 375 Northern Gannets off of Tobay Beach, Nassau 
County, last weekend, and other observers have been recording triple-digit 
tallies from Fire Island, Moriches, and Shinnecock Inlets.

Bobby also saw at least four Wilson's Storm-petrels from Tobay yesterday (13 
June), inspiring Pat and me, with the help of John Gluth, finally to connect 
with five of these birds at Cupsogue last night--the latest date Pat and I have 
gone before recording the species in at least a decade. As I'm writing this, 
Ken Feustel just called with a report of 17 WISPs at Robert Moses SP--the most 
I've heard of by far this season. In other seawatching news, Pat saw a 
Parasitic Jaeger from Cupsogue on Saturday afternoon (12 June), and Pat and 
John Gluth saw a Manx Shearwater last night (I was scoping the bayside at the 
time). The pattern emerging from this season's seawatches, at least so far, is 
low density but average to good diversity.

Like Angus Wilson further east, Pat and I saw a Royal Tern over the ocean 
Sunday morning, at Robert Moses SP, and like Angus, a few dopey ducks can be 
found all along the LI shore: a male Surf Scoter at RMSP yesterday, two Common 
Eiders at Fire Island Inlet thru at least Friday, and two more Eiders recorded 
by Doug Futuyma at Shinnecock Inlet last week. Andrew Baksh has been keeping 
tabs on American Coot, Greater Scaup, and Blue-winged Teal lingering at Jamaica 
Bay (the teal might be breeding there).

I photographed two First Summer Lesser Black-backed Gulls at Democrat Pt on 
Friday evening (not together, but among loafing flocks about a mile apart), and 
one of these had moved to RMSP parking Field 2 by the time I returned to my 
car. Yesterday, Pat and I found an adult-like LBBG at Pikes Beach, then noticed 
it was accompanied by not one but two First Summer individuals. Although the 
presence of loafing immature LBBGs at this season has become increasingly 
familiar, I believe this was the first white-headed, completely yellow-billed 
individual I've ever seen during June on LI.

June is certainly the season for loafing one- and two-year-old charadriiforms 
on LI. Pat and I connected with our first First Summer Least Terns of the 
season on Saturday (one each at Mecox Bay and on the north shore of East 
Hampton, the latter accompanied by at least two Second Summer individuals), and 
First Summer Common Terns are now regular at Cupsogue, following arrival of the 
season's first on 2 June (there were two there, not necessarily the same birds, 
each day this weekend). In other tern news, small numbers of Roseate Terns 
continue to be conspicuous around Fire Island and Moriches Inlets, and Luke 
Ormand, Anthony Graves and John Turner have found at least two pairs breeding 
among Common Tern colonies in the latter area. I saw a Gull-billed Tern at Jam 
Bay on Thursday and Andrew saw the same or another there on Friday; this 
species is often very difficult to find at the height of the breeding season.

White-rumped Sandpipers are still migrating heavily through Long Island: Andrew 
Baksh tallied 10+ at Jam Bay on Thursday and helped Jim Cullen, Sam Jannazzo 
and me tally up about a dozen adults (and one gray First Summer bird) at 
Cupsogue on Saturday. As the northbound flocks of brightly plumaged shorebirds 
move on, they've been replaced by smaller numbers of dull-plumaged 
non-breeders: two Dunlin, 47 SB Dowitchers, 25 Red Knots,  three Black-bellied 
Plovers, etc. at Cupsogue this weekend. In addition to the 47 First Summer SB 
Dows yesterday were two breeding plumaged birds of the prevailing eastern 
subspecies griseus and one spanking adult of the scarcer Prairie-breeding 
subspecies hendersoni--nicely photographed by John Gluth:

http://www.flickr.com/photos/jgluth_brb/

Hendersoni has been regarded as genuinely rare even a little to north of LI was 
thought to be just a scarce southbound migrant July-August here until close 
attention began yielding a handful of May and June records over the last few 
years.

John's flickr site also shows an afflicted Red Knot with tumor-like growths on 
its head and throat--one of two such Knots at Cupsogue yesterday. A similarly 
afflicted White-rumped Sandpiper was photographed in Rhode Island on Saturday, 
and this phenomenon is well known--although again poorly understood--in our 
region during June.  Pat's and my LI/NYC quarterly report for summer 2006 
discusses the matter in some detail at:

[nysbirds-l] LI Birds: Arctic Tern, Hudsonian Godwit, Whimbrel, Cory's Greater Shearwaters+

2010-07-10 Thread Shaibal Mitra
Birding all day with no camera (left at home) and no cell phone (battery died 
early), I  noticed how good it felt to be liberated from these distractions. 
Then things got complicated.

It began raining lightly and Patricia decided not to come out on the flats with 
me at Cupsogue, just east of Moriches Inlet, Suffolk County. I asked her to 
check on me periodically as she birded from the roadway, in case I found 
something really good, in which case I would flail about to catch her 
attention.  My first round of gesturing came not long after we split up, as I 
attempted to indicate the presence of a Whimbrel on the western edge of the 
flats.  Little did I know that Patricia was at that time looking at a Hudsonian 
Godwit on a bar even farther west (a sandy bar that pelicans have been known to 
roost on, visible from a cut in the dune about a quarter of a mile west of the 
Cupsogue parking lot), and she of course could not see me at all from there 
(even if she were inclined to do some flailing of her own).

Proceeding with my birding, I was pleased to see (and hear) eight Lesser 
Yellowlegs in a shallow panne--always a good sign of active migration at this 
salty/sandy site that tends not to hold species like LEYE and Stilt Sandpiper. 
Then I found a beautiful near-adult Arctic Tern. I alternated bouts of waving 
at the dune-line with close study of the tern (it deviated from a full breeding 
adult only in its dusky lesser coverts and only moderately long tail streamers, 
reaching just beyond the wingtips at rest).  As the tide came up, it flew 
toward me showing its translucent primaries and distinctive buoyant flight to 
good effect, and it landed not ten meters from me.  At this point I started to 
have serious misgivings about the virtues of being unencumbered by cameras

Eventually my gesturing (which was now subdued, so as to alarm only savvy 
primates as opposed to naive birds) seemed to produce a result, as I saw 
Patricia making her way out onto the flats. Leaving my scope trained on the 
tern on the deserted flats, I raced a quarter of a mile to meet her half-way. 
That's when she told me about the godwit. It's also when it started to rain 
again. And, back to the north, this is also when some boaters began moving 
toward the tern flock.  I left Pat to try to locate her godwit, took her phone, 
and set off as fast as I could in a desperate bid to phone-scope the tern 
before it was flushed. I failed. Most of the terns settled back in eventually, 
but the Arctic was not among them. Pat failed to find the godwit, too, but with 
only one phone, I had to cross the flats once more to learn this.  She had had 
enough and headed in.

I stayed out stubbornly as the tide came up, hoping that either the tern or the 
godwit would return.  The tern did not, but as I re-checked my flock of 
roosting Willets (50+ adult eastern, no juvs yet, and one first summer 
Western), there was the Hudwit! I phone-scoped it, checked the terns one more 
time, then slogged back across the flats for the sixth time in two hours. Other 
notable birds out there included single Roseate and Royal Terns, and at least 
three hendersoni SB Dows among at least 100 griseus.

When I got to the Beach Hut, Pat had picked up two Greater and one Cory’s 
Shearwaters over the ocean; another 45 minutes of scoping yielded five more 
Cory's Shearwaters and about ten Gannets.

This exciting (but at times frustrating day) began with a nice group of 
shorebirds at Mecox Bay, where there was a yearling Lesser Black-backed Gull, 
the first juvenile Ring-billed Gull we've seen this year, and where 18 Lesser 
Yellowlegs and 15 SB Dows had us hoping that one of Delaware's two Ruffs might 
have been tempted over to us. Mecox looks great and ought to be checked 
thoroughly over the next few days. Sagaponack had flats but few birds, and 
Montauk Pt. was socked in with fog. Things brightened up for us at Big Reed 
Pond in Montauk, where we saw lots of newly fledged passerines and a fresh 
juvenile Bald Eagle (probably a wanderer from down south).

If people check for the Hudwit and Arctic Tern tomorrow, I would suggest 
checking Pikes Beach as well as Cupsogue for the former, and, with regard to 
the latter, keeping in mind that many of our Common Terns have completely red 
bills at this time of year.

[nysbirds-l] LI Bird Notes, 23-24 July

2010-07-27 Thread Shaibal Mitra
Here are a few notes from last weekend on birds not mentioned or emphasized in 
previous reports.

At Jones Beach, Nassau Co., on Friday afternoon, the inclement weather 
discouraged human activity enough to allow birds to use the Short Beach island 
and Field 2 parking areas without much disturbance. At the former, the many 
shorebirds included nine Western (and zero Eastern) Willets—my largest tally of 
inornatus yet this year. Also present there were three adult Gull-billed Terns, 
resting and eating crabs, and at least seven brand-new Least Tern juvs. The 
flock of American Oystercatchers had already grown to 90 birds—all adults or 
older immatures (= zero juvs). A breeding-plumaged Black Tern foraged over the 
bay.

On the ocean side, a surprisingly large group of ragged brown gulls (few adults 
and no juvs) were enjoying a peaceful afternoon on Field 2, at low tide no 
less. Among these were two Lesser-black-backed Gulls, a yearling and a two 
year-old, continuing the trend of summer prevalence that I emphasized back in 
June:

http://picasaweb.google.com/tixbirdz/LongIslandMiscellany2010#

A smaller gull flock at Captree SP, a few miles east along the beach in Suffolk 
Co., featured several brand-new Herring Gulls—undoubtedly from the small 
colonies on the nearby bay islands but reminders of the great colony at Captree 
itself, which was very famous in an earlier era.

At Jamaica Bay on Saturday, it’s worth noting that the previously reported juv 
Least Bittern was undoubtedly a local product, a hint as to how many 
interesting things probably went undetected on and around the bloated and fetid 
East Pond earlier this summer. Juv Forster’s Terns can be studied to great 
advantage there, along with their still-attentive parents, offering terrific 
opportunities to learn vocalizations, plumage features, and habits 
distinguishing this species from the very similar Common Tern. The only Common 
Tern I noticed on the East Pond on Saturday was a fly-over adult that happened 
to call.

Five of us (Pat, Joan, Gerta, Andrew) ran out to Cupsogue later on Saturday, 
where we didn’t add much to the many notable observations recorded by Seth 
Ausubel et al. earlier in the day. This was my first visit out there in two 
weeks, and the most immediately obvious changes involved the fledging of many 
juv Common Terns (80+) and the abrupt and nearly complete withdrawal of Eastern 
Willets. It was heartening to see that the local terns managed to bring off so 
many young despite relentless pressure from campers and their dogs. In contrast 
to the gangs of 90+ adult Willets present just two weeks ago, we found just two 
adults today, along with the only full-grown juv I’ve seen yet this season.  
While searching unsuccessfully for Seth et al.’s Brown Pelican, we turned up 
three juv Oystercatchers, and Royal Terns are finally starting to build up in 
numbers: we saw seven at Pikes Beach plus two more at Cupsogue. Last summer, 
our marsh-nesting birds suffered almost complete nesting failure, due to flood 
tides.

Throughout our visit, actively migrating shorebirds were conspicuous—mostly SB 
Dows and Semi Sands, but also a Whimbrel and several other species. Some of the 
over-summering shorebirds were still present also, including both 
winter-plumaged (= first summer?) Dunlin, but we did not see Schnauzer the 
tumor-afflicted Knot. The most interesting shorebird we saw was a tiny-billed 
Western Sandpiper (photos at site cited above), which will be sure to trouble 
our sleep when we’re gleaning through October’s lingering peeps.

RE: [nysbirds-l] Marbled Godwits

2010-08-05 Thread Shaibal Mitra
After I spoke with Hugh, Pat found a third Marbled Godwit on the pelican bar, 
about half a mile west of the main flats at Cupsogue, and north of the camper 
colony along the 4-wheel drive track that leads to the inlet. Later we learned 
that Jim Cullen had seen the two godwits on the main flats earlier in the day. 
These two birds fed actively in the deepening water at the northeast peak of 
the main flats, then moved as the tide rose, first to the southeast corner, and 
finally to the grassy patch near the southwest corner--the very spot favored by 
the Hudsonian Godwit a few weeks ago.

Photos: http://picasaweb.google.com/tixbirdz/LongIslandMiscellany2010#

Perhaps arriving with the Modwits from the Canadian prairies were my first two 
juvenile Western Willets of the season (four-five adults were also present). We 
also finally found good numbers of juvenile Eastern Willets (six at Cupsogue, 
13 at Pikes Beach). I wonder whether these were locals, or whether they might 
have come from down the beach (e.g., southeastern New England).

An adult Black Tern and a fresh juv Forster's Tern were at Cupsogue, and the 
number of Royal Terns at Pikes Beach swelled to 49.

A nice day at the beach!

[nysbirds-l] LI Bird Notes: Belated report of seabirds and shorebirds

2010-08-17 Thread Shaibal Mitra
Pat saw the continuing SY Glaucous Gull at Orient Pt on Friday evening. We both 
saw it as our ferry pulled in on Saturday evening, but it flew off toward 
Gardiners Island before I could get any photos. I noticed that its right leg 
drooped as it flew, suggesting that an injury might underlie its persistence 
through the summer.

If anyone has good photos of this seasonally unusual bird, I would be grateful 
to see them. Folks with long memories and strong stomachs for staring at 
tattered immature gulls might remember another SY Glaucous Gull at Shinnecock 
Inlet, back in the summer of 2001. That bird inspired some controversy because 
a leucistic Great Black-backed Gull had been misidentified as a Glaucous at the 
same site the previous winter and apparently persisted there for many months. 
We had intimate studies of the 2001 GLGU (and the odd GBBG too), and I’m 
completely satisfied regarding their identities. I think this year’s bird is a 
GLGU, but I’ve only seen it briefly on a couple of occasions, with binoculars 
only, and I’d appreciate critical details/photos if anyone has them.

Birding Cupsogue on Sunday morning, we saw six Marbled Godwits. These birds 
move frequently between the main flats north of the parking lot, the “pelican 
bar” to the west, and Pikes Beach to the east, and their groupings are very 
fluid.  For instance, on Sunday, I was watching one on the main flats when Pat 
and Joan Quinlan called to let me know that five were in transit from the 
pelican bar toward me. One of these quickly joined the one I’d been watching; 
another flew north out of sight behind a big spoil island a few minutes later; 
and the other three eventually showed up on the edge of the barrier beach.

While eating lunch at the Beach Hut, we noticed a good flight of inshore Cory’s 
Shearwaters. We tallied 87 from 13:00-14:00, along with a Manx Shearwater, 8 
Gannets, and a Black Tern.

A little further to the east, Andy Guthrie and Angus Wilson also saw this 
flight and furthermore picked out two Greater Shearwaters. These two added 
another bird to the day list when they visited Cupsogue on the falling tide, 
and it was a big one: a Brown Pelican doping about on the northeast peak of the 
main flats around 18:30.

Yesterday (Monday) I visited Jamaica Bay briefly after begging out of a very 
slow banding session at Fort Tilden (sorry Juliette!). Apart from the 
continuing Marbled Godwit and intimate studies of molting Western, 
White-rumped, and Stilt Sandpipers, my highlight there was a juvenile 
Long-billed Dowitcher that allowed close study alongside an adult Long-bill and 
both adult and juvenile Short-bills. I would appreciate feedback on the 
identification of this bird because it seems very early for a juvenile 
Long-bill, and because its tertials showed a bit more patterning than expected 
on a typical specimen. Structurally, and in terms of its overall plumage, I 
thought it was pretty clearly a Long-bill:

Andrew’s ethical teachings must be rubbing off because I didn’t even consider 
trying to make it call!

[nysbirds-l] 22 Godwits at Cupsogue!

2010-08-22 Thread Shaibal Mitra
Some readers might recall recent efforts by various observers to nail down a 
tally for the Marbled Godwits in the Cupsogue, Suffolk County, area. This 
afternoon, Andy Guthrie, Patricia Lindsay and I counted zero at Pikes Beach, 
then six on the northeast peak of the main flats at Cupsogue, then one on the 
“pelican bar” to the west. Looking northeastward from our vantage above the 
last site, we saw plenty of godwits remaining on the main flats. In fact, by 
the time we sorted them out, we had tallied nine Marbled and a tight flock of 
twelve Hudsonian Godwits there, as well as the one Marbled on the bar below us!

We scrambled to get down onto the flats as quickly as we could, but by the time 
we got there, the Hudsonians had departed. A tenth Marbled was now present on 
the main flats—probably the one from the pelican bar, as that bird was no 
longer there a few minutes later. When we checked Pikes a little later, no 
godwits were present.

The weather throughout our visit was very unsettled, with occasional light rain 
and an easterly breeze. During our initial stop at Pikes, we had been impressed 
by a fly-over flock of 40+ Lesser Yellowlegs plus at least one Stilt Sandpiper. 
We remarked on the improbability that these panne and pool aficionados would 
tarry for long on Cupsogue’s sandy flats, but welcomed them as an indication 
that shorebirds were on the move.

After earlier (12:30-4:20), unremarkable visits to Jones Beach west end
and Oceanside (no Buff-breasted Sandpiper or Avocet), I paid a visit to
Cow Harbor Park in Freeport ~4:30 to look for shorebirds on the pond and
marsh. The latter had low numbers of common species (Black-bellied and
Semipalmated Plovers, Greater Yellowlegs, Semi and Least sandpipers, and
S-b Dowitcher, all widely scattered in the shallower pools. The pond
harbored a substantial gathering of both white egrets, a few night-herons
(both species), several Glossy Ibis and 2 Green-winged Teal. Shorebird
numbers were modest and composed of the aforementioned species with the
following additions-- White-rumped Sandpiper and Lesser Yellowlegs (1 each).
The highlight of the visit wasn't a waterbird though. On my way to the
pond I heard a couple shrill, rolling vocalizations--very psittacine-like.
From among the bevy of Tree swallow swarming overhead a pair of larger,
long-tailed birds emerged and landed in a small tree between the parking
lot and tennis courts. Before I was able to close enough ground on the tree
both birds lit out, again calling. Silhouetted against the gray sky little
of the bird's plumage color or pattern could be perceived. But based on
perceived size, and more importantly the additional calling, I could tell
they were MONK PARAKEETS. The birds flew out of sight toward the residential
area to the north. Anyone know if there are any established colonies in
the area?

[nysbirds-l] Saturday Morning Flight at Fire Island

2010-08-29 Thread Shaibal Mitra
There was a nice morning flight at Robert Moses SP, Suffolk Co., yesterday 
morning (28 Aug 10).

Swallows were moving heavily, passing at a rate of ca. one per second through 
the morning. Barns outnumbered Trees by about four to three, Banks were easy to 
find (we estimated ca. 50),  and we noted two Cliff Swallows. We did not see a 
single Rough-wing, underscoring the scarcity of this species on the outer beach.

Many species were noted migrating, including a Great Blue Heron, three Merlins, 
an American Kestrel, and many passerines.  Among ten species of warblers, the 
most numerous were Yellow (15), Common Yellowthroat (15), Northern Waterthrush 
(9), and Am. Redstart (6); the most notable were single Blue-winged and Cape 
May (the former always very scarce on the outer beach).

As noted by many observers lately, Red-breasted Nuthatches seem to be mounting 
a good flight this year (we noted 5). A single Purple Finch was only mildly 
surprising, as this species often appears on the coast in small numbers around 
Labor Day, a month or more ahead of the main flight.

As with the spring flight of 15 May, it is interesting to compare our morning 
with Rob Jett's data from Prospect Park. The two Veeries we recorded at RMSP 
were two more than one usually finds on the barrier beach and, together with 
Rob's big inland count, are evidence of a significant push of Neotropicals 
Friday night.

We also noted an mass-emergence of ants, attended by feasting Laughing Gulls. 
These events probably occur every year, and I know Tony Lauro wrote an article 
on the topic many years ago. Here is a link to a photo of an ant from a similar 
event last year:

These birds, all juvs as expected, were present in the beach-side area

Catching up on a few birds from Sunday, Fire Island was flanked by adult/juv

This morning at Jones Beach, I observed 6 (possibly as many as 9) Baird's 
Sandpipers. These were not in the swale, where Baird's are often found, but, 
continuing past the swale toward the beach and turning left, at a rain pool. A 
group of 6 was present briefly around 10:30. I got off one long distance 
picture that captured 4 in the frame, before they took off. See 
http://www.hmana.org/steve/bairds.htm . The birds seemed flighty and not in 
need of much reason to move on. Certainly, from this distance, it wasn't me 
that put them on their way. Earlier, at about 9:35, there was a single 
individual. About 15 minutes later, I saw another Baird's that took off with 
another bird that I didn't get a chance to ID. In these cases, my movements may 
have been responsible for causing them to leave. I say all this because I got 
the feeling that these were migrating through and just making brief stopovers, 
and the group of 6 didn't include the earlier birds. But good luck to anyone 
that wants to check it out tomorrow.

One other shorebird note was a still present Piping Plover. Otherwise, the 
routine stuff. On many days, seeing 6 Baird's together would make for the 
exciting moment of the day. But later this day, I laid eyes on my first ever 
New York record of Variegated Meadowhawk, a western dragonly with known 
vagrancy tendencies (I saw one in Cape May 15 years ago). This one was at Lido 
Beach Nature Area. This picture can be seen at 
http://www.hmana.org/steve/corruptm.htm . After 5 days of predominantly north 
and northwest winds, there are loads of migratory dragonflies (and butterflies) 
along the beach.

[nysbirds-l] Morning Flight at Fire Island

2010-09-05 Thread Shaibal Mitra
Today I did a two-hour morning flight survey at Robert Moses SP, southwestern 
Suffolk Co., with help from Pat Lindsay and Brent Bomkamp and his dad.

Winds were straight out of the west, which is not conducive to nocturnal 
migration, but we saw a fair amount of activity among diurnal migrants.

As usual, almost everything was flying west down the beach. Notable species 
included:

6 Green-winged Teal flying due north at 6:30
2-3 Whimbrels--one heading west at 7:15 and two heading east at 7:30
1 imm Red-headed Woodpecker
37 Eastern Kingbirds
35 Cedar Waxwings
1 Dickcissel
117 Bobolinks
6 Baltimore Orioles (plus others raiding the chokeberries)
2 Purple Finches (plus two more hanging around)

Among birds not making directed movements were 5 RB Nuts, 2 Western Palm 
Warblers, Prairie Warbler, Least Flycatcher, Veery, and Northern Gannet.

We heard through Ken Feustel that Bob Paxton saw a Lark Sparrow yesterday near 
the entrance to the four-wheel drive road (= western turn-around of parkway).

Subject: LI Birds: Parasitic Jaegers, Common Eiders, Clay-colored Sparrows+

There was a modest morning flight at Robert Moses SP today, with two American 
Pipits and a Purple Finch being perhaps the most noteworthy among the birds 
overhead. A lot of late fall migrants moved in today, including Golden-crowned 
Kinglet, Brown Creeper, Slate-colored Junco, and at least 25 Eastern Phoebes 
between RMSP and Cedar Beach.

The ocean was very active, with large numbers of Laughing Gulls and smaller 
numbers of Forster's, Common, and Royal Terns. Among the prey these birds were 
seeking was a least one small passerine that was captured over the waves by a 
Laughing Gull, and then sought by two Parasitic Jaegers that harried the gull 
down to the water. We eventually saw at least five Parasitic Jaegers off of 
Field 2, as well as two migrating Common Eiders (spotted by John Gluth--first 
of season this far west on LI) and a Juvenile Am. Golden-Plover. A first-winter 
Herring Gull at Field 2 showed several characters associated with European 
subspecies. Bob Grover and John Gluth shared most of these birds with us and 
also reported that the Clay-colored Sparrow at the eastern end of Field 2 
remained cooperative this morning.

On a tip from John (and also Vinnie Pellegrino), we visited Blydenburg County 
Park in Smithtown, and, with help from Brent Bomkamp, we savored impressive 
local early fall counts of many waterfowl (e.g., 9 Pied-billed Grebes, 189 
Baldpates, 74 Gadwalls, 17 Pintails, 5 Shovelers, and 8 Ring-necked Ducks)--as 
well as the two continuing Common Moorhens.

We spent the afternoon at Sunken Meadow SP, on the North Shore of LI. 
Highlights here were single Clay-colored (possibly the first for this park, 
according to Norm Klein) and Lincoln's Sparrows.

A photo of the Sunken Meadow CCSP can be seen at:

[nysbirds-l] Cattle Egret and More Lesser BB Gulls, Robert Moses SP, Suffolk County

2010-10-01 Thread Shaibal Mitra
The Cattle Egret found by Bobby Rossetti and reported by Dave Klauber was still 
present near the northeast corner of Field 5 at 5:30 this evening.

Present then at Field 2 were 6 LBBGs in a discrete flock: 2 near adults, a 3rd 
Winter, and 3 juvs.

At lunchtime, Patricia found a second near adult LBBG at Heckscher (just one of 
that appearance was present there is morning), bringing our tally today to 11 
LBBGs, including 6 juvs--and we covered just three sites in southwestern 
Suffolk (Heckscher, Captree, and RMSP).

As noted by Angus, the gulls appeared to be arriving and departing in a dynamic 
fashion, and our impression (pending photo analysis) was that there was no 
obvious overlap among the 5+ individuals observed yesterday at RMSP and the 6+ 
observed there today.

[nysbirds-l] LI Birds: Two Franklin's Gulls+

2010-10-27 Thread Shaibal Mitra
Ken Feustel found a first winter Franklin's Gull today at Robert Moses SP, 
Field 5, in southwestern Suffolk County, LI.

He called a number of local birders, but none of us arrived in time to see it 
before it flew out over the dunes. Still present when I got there were four 
Lesser Black-backed Gulls: two adults and two juvs (I had seen another juv 
earlier, flying alongside me as I crossed the RM Twin Causeway).

Disappointed, the birders began to disperse, some to check Field 2, others the 
ocean beach. Not to be denied, Patricia Lindsay decided to check Captree SP, 
although she had no optics whatsoever and  was hurrying to get back to work. 
Leaving RMSP a little after her, I was independently heading for Captree when 
she called to tell me she had found an adult Franklin's Gull!

I arrived quickly, we shared binoculars, scope, and cell phone duties, and 
marveled at the nature of the universe.

[nysbirds-l] Large Morning Flight, Long Island

2010-10-29 Thread Shaibal Mitra
I observed an hour's worth of a very large morning flight Robert Moses SP, LI, 
this morning. Although not on a scale comparable to massive flight of 3 Nov 
2006 (see below), there were very large numbers of Red-winged Blackbirds, 
Myrtle Warblers, Tree Swallows, American Robins, Cedar Waxwings, American 
Pipits, Pine Siskins, American Goldfinches, and Purple Finches in the air. 
Reminiscent of 3 Nov 06, nocturnal migrants that were not obvious in the 
morning flight itself, such as sparrows and Hermit Thrushes, were percolating 
out of puckerbrush by the time I left.

Hi everyone,

The morning flight was very impressive today  along the barrier beach at Robert
Moses State Park, Suffolk.

Between 6:45 and 8:15, my estimates of the numbers of birds sweeping
along the dunes were on the order of 50,000 Red-winged Blackbirds, 10,000
American Robins, and 1,000 Cedar Waxwings. There were at least 3,000 White-
throated Sparrows, and 1K each of Junco and Myrtle Warbler on the ground. GC
Kinglets, a staple feature (in the multi-hundreds) of recent coastal flights, 
were
almost completely absent, but numbers of RC Kinglets, Hermit Thrushes, Phoebes
were impressive.

I wanted to get the word out in case others are able to bird the coast today, 
and to
compare migration notes with observers in other parts of the state.

Best,
Shai

[nysbirds-l] Fire Island Birds: Cave Swallows++

2010-10-30 Thread Shaibal Mitra
Robert Moses SP featured an exciting morning flight again today, with excellent 
volume and variety of diurnal migrants, but numbers of re-orienting nocturnal 
migrants (e.g., Myrtle Warblers) were much lower than yesterday's.

Highlights included four Cave Swallows (pairs around 8:30 and 9:00), a 
Baltimore Oriole around 9:15, a Short-eared Owl around 9:30, single Red-headed 
and Red-bellied Woodpeckers around 10:00, as well as 51 Rusty Blackbirds, five 
Royal Terns, three Common Eiders, and 15 Red-throated Loons.

I spoke with Paul Buckley around mid-day, and he related seeing two Cave 
Swallows along the Hudson River in Riverdale, Bronx County.

[nysbirds-l] Common Ground-Dove at Captree

The Common Ground-Dove was still present past 4:00 pm, along the northern edge 
of the eastern-most parking lot at Captree SP, Suffolk Co., LI.

On at least four occasions, the bird flew out of sight into the vegetation to 
the north, but it always reappeared in its favorite swath of grass, near the 
northwest corner of the lot.

[nysbirds-l] Common Ground-Dove Continues + Western Kingbird

2010-11-01 Thread Shaibal Mitra
The Common Ground-Dove continues at Captree, although it is sometimes absent 
for half an hour or so at a time. At 9:50, during one of the dove's absences, a 
Western Kingbird appeared along the same edge of vegetation. I had to leave 
shortly thereafter, but I heard from Lloyd Spitalnik that the dove reappeared 
in its usual haunts and gave a good show for all its newly assembled devotees. 
At last report, neither dove nor kingbird were visible, but I would think that 
patient scanning of the northern edge of the easternmost lot is likely to be 
rewarded.

[nysbirds-l] Common Ground-Dove Continues!

2010-11-03 Thread Shaibal Mitra
Joe Giunta and party have re-found the Common Ground-Dove at Captree SP, very 
near where Claude Bloch reported it yesterday.

The bird is along the driveway that leads to the boat-launch area.

My advice would be to park in the main parking lot (in front of the Captree 
Cove restaurant), and then to view the boat-launch driveway from either its 
east end (near the entrance to the main parking lot) or its west end (near the 
southwest corner of the main parking lot).

The Western Kingbird and Dickcissel were also present again this morning.

[nysbirds-l] Sit-and-Wait (Good) vs. Active Foraging (Bad) Strategies

2010-11-05 Thread Shaibal Mitra
I spent a little over an hour at Captree this afternoon, during which the 
Common Ground-Dove was seen just once, and for just a few minutes.

About a dozen birders were searching for the bird, and it became quite clear to 
me that their mostly uncoordinated efforts were not likely to produce favorable 
outcomes.

My conclusions are as follows:

1. Newly arriving searchers should discreetly approach someone already present, 
exchange cell numbers, and make an effort to fit into a coordinated strategy. 
If the first person you approach turns out to be a misanthrope, find a more 
civic-minded birder--there will be many there tomorrow.

2. It is best to wait quietly and motionless, preferably in a car, while 
scanning an area where the bird has been seen in the past. This bird likes to 
forage in short grass, along the margins of taller, denser vegetation. All of 
the margins the bird has favored are relatively narrow, so birders walking or 
standing in a prime spot are not likely to see the bird in that spot.

3. During periods when the bird is not being seen, it is grossly 
counter-productive for multiple birders to walk and drive repeatedly along all 
of the preferred margins.

4. All of the best margins can be surveilled from as few as six fixed points, 
four of which can be worked from a vehicle parked at a discreet distance from 
the margins in question:

   a. a point near the northeastern corner of the east lot, giving vantages of 
the north edge and the eastern foot-path toward the fishing piers.
   b. a point near the northwestern corner of the east lot, giving vantages of 
the north edge and the western foot-path toward the fishing piers.
   c. the extreme southwestern corner of the main lot, giving vantages of the 
western half of the driveway to the boat launch area.
   d. a point giving vantages of the eastern half of the driveway to the boat 
launch area, and some of the roadside margins east of the toll booths.
   e. a point near the eastern end of the south lot, giving vantages of the 
driveway to the south lot.
   f. a point near the exit of the west (boat launch) lot (where it exits back 
onto the Ocean Parkway), giving vantages of the roadside margins west of the 
toll booths.

5. When news of the bird's presence is circulated, people moving over in hopes 
of seeing it should take great care to avoid approaching by a track that might 
disturb the bird. Pay close attention to cues from people already on the bird, 
and, if in doubt, call one of them for a suggested route.

[nysbirds-l] Identity of Jones Beach Shrike

2010-12-01 Thread Shaibal Mitra
A shrike present at Jones Beach West End, Nassau County, LI has been identified 
by many as a Northern Shrike, but a considerable amount of back-channel 
discussion has questioned whether it might actually be a Loggerhead.

When I finally saw this bird well this past weekend I was already aware of the 
debates surrounding its identity, so I made an effort to evaluate  the various 
characters that have been proposed in support of each species. As might be 
suspected multiple features have been proposed to support each view, so the 
question is how to evaluate the relative reliability of each character.

To me, the bird appeared relatively small and quick (vs. the large and lanky 
impression usually imparted by Northern Shrike), with a relatively large head, 
rounded crown, and short bill--all consistent with Loggerhead Shrike. Also 
consistent with Loggerhead Shrike was the relatively dark gray tone to its back.

Features more consistent with Northern Shrike include: extensively pale base to 
lower mandible, heavily hooked upper mandible, the shape of the black mask 
behind the eye, obvious gray barring on the breast in the absence of any 
barring on the back.

The appearance of this bird's mask in the area of the eye itself and in front 
of the eye seems equivocal and has been argued in both directions, but I find 
it easier to find photos of Loggerheads that match its facial appearance than 
photos of Northerns that do so.

Taking these features individually, I think that individual variation could 
account for many discrepancies either way. For instance, it seems plausible 
that some Northern Shrikes could have small bills and that some Loggerheads 
could have heavily hooked bills, etc.

To me, the difficult questions are:

1. Could a Northern Shrike could look so small, quick, and large-headed?

2. Could an immature Loggerhead Shrike show a pale-based mandible and ventral 
barring in the absence of dorsal barring?

3. Is this bird's mask pattern possibly diagnostic, despite the conflicting 
impressions of local observers?

Any constructive answers to these questions would be greatly appreciated!

RE: [nysbirds-l] Identity of Jones Beach Shrike

2010-12-01 Thread Shaibal Mitra
It's worth noting that mid 20th Century birders knew Loggerhead Shrike as a 
regular fall vagrant on LI and coastal southern New England, perhaps comparable 
in frequency to Western Kingbird. These fall Loggerheads mostly occurred much 
earlier than Northern Shrike would be expected, from late August through 
October, but there are many critically identified records from November and 
December--as attested by Kevin's Thanksgiving specimen from Mecox. Because 
these vagrants vanished in step with the nearest, northeastern breeding 
populations, it is likely that many derived from those sources. Even so, we 
actually know very little about the precise origins of our coastal 
vagrants--even the frequent ones like Western Kingbird and Lark Sparrow.

Funny, but I was going to ask about this shrike yesterday to see if anyone had 
taken a long hard look at it.  I saw another photo and I just can’t make it 
into a Northern Shrike.

I have put some photos of a specimen from the Cornell Museum of Vertebrates 
that might be of interest at
http://picasaweb.google.com/KevinJ.McGowan/SpecimenExamples

It is a hatch year female taken in Mecox, Suffolk Co. on 26 November 1946.  It 
shows neat light barring across the chest, a gray unbarred back, and a pale 
patch at the base of the bill.  Several individuals in the collection looked 
similar.  The Jones Beach individual looks very similar to my eyes, except that 
it doesn’t have the retained juvenal wing coverts, but that molt can be 
variable among individuals.

Shai’s real Northern Shrike photo shows very substantial contrast in shape, 
bill shape, mask size, coloring, and markings.  I was not able to find a single 
specimen of Northern Shrike in the Cornell collection that even remotely looked 
odd or like the Jones Beach bird.  Not to say that the collection encompasses 
the entire variation, but they all looked pretty much alike.

Interesting bird.  Here’s hoping it really is a young Loggerhead; the 
population could use it!

[nysbirds-l] Captree CBC

2010-12-20 Thread Shaibal Mitra
The Captree CBC was conducted yesterday on a very pleasant winter day for 
birding.

A couple of bouts of sustained cold prior to the count produced extensively 
frozen conditions, including portions of Great South Bay, and quite a few 
ice-sensitive species were scarce or absent.

Highlights among the 119 species tallied included the following:

6 Snow Goose (Gardiner)
16 Wood Duck (Belmont)
2 Great Egret (Heckscher  East)
3 BC Night-Heron (Gardiner  Seatuck)
1 Osprey (Connetquot)
1 Bald Eagle (Heckscher)
2 Virginia Rail (Seatuck  East)
6 Killdeer (North, Gardiner,  Heckscher)
3 Wilson's Snipe (Seatuck  Heckscher)
1 Iceland Gull (Seatuck)
1 Black-legged Kittiwake (Fire Island)
5 Razorbill (Fire Island)
2 Monk Parakeet (North)
2 Great Horned Owl (North  Seatuck)
5 Yellow-bellied Sapsucker (North, Belmont, Gardiner, Connetquot,  East)
1 Eastern Phoebe (Connetquot)
1 Marsh Wren (Seatuck)
1 Eastern Bluebird (Seatuck)
2 Brown Thrasher (Jones  Seatuck)
14 American Pipit (Fire Island)

RE: [nysbirds-l] Trumpeter Swans discover eastern Long Island

Subject: [nysbirds-l] Trumpeter Swans discover eastern Long Island

Trumpeter Swans are an increasingly familiar sight in western, central, and to 
some extent northern New York State, especially in the winter when parties of 
birds move down from Ontario in search of open water. Evidence suggests that 
the bulk of the NY population is derived one way or the other from the 
reintroduction program in Ontario. This ambitious project is based at Wye Marsh 
in Midland ON, which is near the southeastern corner of Georgia Bay on Lake 
Huron. Ontario raised swans have stayed to nest at a few spots within NYS and 
their offspring have spread further afield. Many of the Ontario birds are wing 
tagged (yellow with a unique three letter/number code) so their movements and 
survival can be easily tracked. There are other reintroduction programs (e.g. 
Ohio) but we await solid proof that any of their birds have reached into NYS. 
Unfortunately, few of the birds hatched in NYS have been marked and we have 
little information on their survival, movements or ability to nest successfully.

Trumpeter Swan have remained very scarce in the eastern and southeastern 
portions of the state but this seems to be changing. On Monday, Bob Wilson 
found a wing-tagged Trumpeter Swan (number 'A60') at Agawam Lake in 
Southampton, Suffolk County. This is 28 miles from Yaphank, also in Suffolk Co, 
where two untagged Trumpeters have returned for another winter.  According to 
Harry Lumsden of the Ontario Trumpeter Swan Restoration Program, 'A60' is a 
female that was hatched in 2009 by two tagged swans (981 and E51). She was 
banded at Hillsburg ON (northwest of the Lake Ontario shoreline) on 7 Oct 2009 
and then resighted at several location within southeastern Ontario during the 
following winter, spring and summer. In July of this year, A60 was found 
injured in Rosemount ON, taken into rehab and then released a short while later 
near Mansfield ON. There have been no additional reports of this bird until 
now. Are A60 and the Yaphank pair harbingers of changes to come? I would 
imagine the milder marine climate and less extensive snowcover of Long Island 
might offer an attractive and reliable wintering ground for these long-lived 
birds. Time will tell.

NYSARC is actively monitoring the status of Trumpeter Swan in anticipation of 
adding the species to the official New York State Checklist. Guidelines have 
been established to help decide when a species can be considered 
self-sustaining (remember the fate of Eurasian Skylark and European Goldfinch) 
and in the Committee's opinion this has not been met quite yet. Monitoring the 
movements of identifiable individuals such as A60 is extremely useful in this 
process and NYSARC encourages submissions of marked birds or birds from areas 
where Trumpeter Swans remain very rare.

RE: [nysbirds-l] Trumpeter Swans discover eastern Long Island

2010-12-23 Thread Shaibal Mitra
I think Andy is being very diplomatic here, but to question whether 
re-introduced Trumpeter Swans are established in the Great Lakes region is to 
contradict the conclusions of not only the Ontario committee, but also those of 
Illinois, Wisconsin, and Minnesota.

If one accepts that established populations exist in the region, as all of 
those committees do, then it is illogical to use local establishment (i.e., 
fully established breeding populations in NYS) as the criterion for acceptance 
here; instead, simple occurrence of individuals attributable to those 
populations will do. This is how House Finch got onto the checklists of every 
state in the eastern US beyond its NY origins, and how Eurasian Collared-Dove 
irrupted out of Florida.

Anyone can choose to question the conclusions of those other committees if they 
choose, but is it really appropriate for NYSARC to assume responsibility for 
deciding whether or when the populations in Ontario and elsewhere around the 
Great Lakes have satisfied NYSARC's definition of establishment?

Subject: Re: [nysbirds-l] Trumpeter Swans discover eastern Long Island


As a member of the New York State Avian Records Committee (NYSARC), I can 
provide some insight into where the Committee currently stands on this issue.  
This is something that NYSARC has discussed annually for at least the past 
several years.

It is true that the Ontario Bird Record Committee has added Trumpeter Swan to 
its list (in 2007) based on their opinion that the population there is 
self-sustaining, but in the opinion of NYSARC it's not clear that there has 
been a long enough period of self-sufficient breeding success to consider such 
a long-lived species truly established.  Trumpeter Swans can live for 20-30 
years, so many of the wild born birds are most likely still only first or 
second generation.  The existing population in Ontario has been supplemented by 
continued introductions until as recently as 2006, and a large portion of the 
population has been sustained in winter by supplemental feeding programs.  It's 
not clear how well the population will thrive without these human 
interventions.  There is a continent-wide survey of Trumpeter Swan populations 
conducted every five years - the most recent in 2010, the results of which have 
not yet been published.  NYSARC will use this as part of the continuing 
evaluation as to the current status of the species.

NYSARC recently published a summary of the status of Trumpeter Swan in New York 
State, available here: 
http://www.nybirds.org/KBsearch/y2007v57n1/y2007v57n1p2-8sherony.pdf

[nysbirds-l] Southern Nassau County CBC Results

2011-01-05 Thread Shaibal Mitra
The Southern Nassau County Christmas Bird Count was conducted on Saturday, 1 
January 2011, by 61 participants. This represents the 71st time this CBC has 
been held since its inception in 1932 (there were several years with no count 
during the 1930s and 1940s).

A total of 125 species was recorded (plus Ipswich Sparrow), a little below the 
20-year average of 128. The weather was good on count day, but prolonged 
freezing conditions during December clearly impacted a variety of species. In 
general, this year's results struck us as rather average, with few really 
exceptional species and few really bad misses (our worst misses this year 
involved species we've knowingly struggled with in recent years).

In selecting the unusual species named below, we included a few that, although 
they are quite regular on this count, are nevertheless rare in NYS in winter. 
Some species that we would ordinarily expect on this count, but which were 
perceived as good finds this year owing to the cold early winter weather, are 
highlighted as ice-sensitive saves. Several species are widely expected on LI 
or NYS CBCs in general but are nevertheless very difficult in southern Nassau 
County. These are difficult to categorize as either highlights or low-lights, 
but for convenience we've lumped a few of these local oddities in with the low 
counts and misses.

Many thanks to all those who participated, and Happy New Year to all!

RE: [nysbirds-l] Pinelawn Long Island; Grtr White-Fronted Geese Barnacle Goose

2011-01-11 Thread Shaibal Mitra
When Ken Feustel called to tell me he was looking at the Barnacle Goose at 
Pinelawn, it couldn't have been long after Jean's post.

I reached the Farmingdale area at 1:30 and found the Barnacle Goose just to the 
south of St. Charles Cemetery's Wellwood Ave entrance, with a small flock of 
Canada Geese. Next I drove the short distance north and east to Pinelawn, where 
I saw about 1,500 Canada Geese but was unable to pick out any white-fronts.

Returning to St. Charles, the Barnacle was still present and enjoyed by several 
newly arriving birders--but then vanished abruptly, although none of us noticed 
any geese leaving the area. We gave it a little longer, guessing it was hidden 
behind Canadas or in a declivity, but without success. Meanwhile it was obvious 
that flocks of geese were leaving the Pinelawn area and flying east.

Several of us then drove to Belmont Lake SP, where many of these geese tend to 
roost. Doug Gochfeld picked out a nice Richardson's Goose--
photo at: 
http://picasaweb.google.com/tixbirdz/LongIslandMiscellany2011#5561042999063891890
--but I gave up early and headed home.

Just now, Doug texted that the Barnacle flew in at Belmont Lake at 5:12, 
furnishing some more data on the patterns and timing of these birds' local 
movements. We shall have to wait and see how tonight's storm affects things.

[nysbirds-l] LI Barnacle Geese

2011-01-12 Thread Shaibal Mitra
I don't have any updates from today, following the snow storm, but I've 
received some very interesting information regarding the recent reports of 
Barnacle Geese in western Suffolk County, LI.

First, from Tim Dunn, I learned that he observed a Barnacle Goose at Pinelawn 
Memorial yesterday afternoon at the same time I and others were watching a 
Barnacle Goose at St Charles Cemetery--just a kilometer or two away.

Then, today, I learned from Gary Strauss that the Barnacle Goose he saw at 
Pinelawn Memorial yesterday was banded on both legs; the bird that several of 
us studied at St Charles on Saturday appeared to me and to Patricia Lindsay to 
be unbanded.

To give some background, an unbanded Barnacle Goose was present in this area 
from Nov 2008 to Feb 2009--

29 Nov 08 St Charles Cemetery

15 Feb 09 St Charles Cemetery

I can't comment on the presence/absence of bands for the observations from 
Belmont Lake SP on Saturday and last evening (at that site, the birds are seen 
on the water), or from St Charles yesterday afternoon (owing to distance and 
terrain), but it would seem that there are two Barnacle Geese in western 
Suffolk County!

[nysbirds-l] Signs of Spring on LI: Oystercatchers and Killdeer

2011-02-18 Thread Shaibal Mitra
This afternoon as I was scoping flocks of Brant and goldeneye at the Fire 
Island Inlet, seven American Oystercatchers came Wheep-ing in from the west 
and landed on the Oak Beach bar. They were the only shorebirds I saw until I 
came across a Killdeer along the roadside at Robert Moses SP. We had seen 
another Killdeer at West Gilgo last Friday, whose status (winter 
survivor/spring arrival) we deemed indeterminate. Today's bird, in addition to 
be a week later, was much farther from any kind of viable winter habitat.

[nysbirds-l] LI Birds: Northern Shrike, Richardson's Goose, Euro GW Teal+

2011-03-06 Thread Shaibal Mitra
As is often the case, today's rain took longer than expected to reach eastern 
LI, and Patricia Lindsay and I enjoyed a partly sunny (but blustery) day 
birding around Montauk. We collaborated at times with Mike Higgiston and Eileen 
Scwhinn.

Pat and I began at 7:00 with an hour spent working the Amagansett beach front, 
looking in vain for Eared Grebe. Highlights here were a female King Eider and 
12 Razorbills.

The scoter and eider spectacle off of Montauk Pt. continues to be spectacular. 
Here we also found six more Razorbills (these and those seen earlier were all 
still in winter plumage), an immaculately white-headed adult Lesser 
Black-backed Gull, and a fly-by Great Cormorant in gorgeous breeding plumage.

By the time we came past again, some geese had dropped into the horse farm at 
Deep Hollow. Among these was a Richardson's Cackling Goose and four Killdeer. A 
Red-necked Grebe was present close in below the bluffs at Culloden Pt, perhaps 
sheltering from the violent southerly winds.

Forgoing that kind of prudence we spent another hour at Ditch Plains, looking 
in vain for Eared Grebe. Highlights there were 15 Purple Sandpipers and two 
exceedingly obliging Common Redpolls.

At Napeague, we finally connected with the long-staying, but often elusive, 
immature Northern Shrike. We also noted that Larry the Lesser Black-back 
retained a little dusky streaking on his face, unlike the individual at the 
point.

At the duck- and goose-feeding pull-out on David's Lane, to the north of Hook 
Pond, we found five Wood Ducks lurking just a little more coyly than the 
histrionic Chinese Swan Geese and Pekin Ducks. We were intrigued to notice 
several other, less flamboyant species availing themselves of the copiously 
proffered Wonder Bread and Froot Loops: six Rusty Blackbirds and a Gray 
Catbird. For those inclined to photography, the scene there offered many 
advantages: knee-buckling views of Wood Ducks and Rusty Blackbirds--plus a 
clamorous backdrop of crowds of people treating wildlife unethically!

The waterfowl on Fort Pond in Montauk included a Shoveler, 12 Canvasbacks, and 
26 Ring-necked Ducks; those on Hook Pond in East Hampton included good numbers 
of all three mergansers, five American Green-winged Teal, and a Coot; those on 
Shorts Pond in Bridgehampton were quite varied and included 12 Pintails and 40 
Ruddy Ducks (the latter don't usually return after being frozen out--where were 
they a few weeks ago?), as well as two drake Eurasian Green-winged Teal among

white vertical bars on any of their four breast-sides; bold pale lines 
delineating the facial feather tracts; and pale marks anterior to the black

RE: [nysbirds-l] Ross's Geese

2011-03-07 Thread Shaibal Mitra
Hi John and all,

Instead of a can of worms I'd call this a useful conversation.

Shawn is correct that nine Ross's Geese were recorded at Montezuma on 24 Oct 
2008, and I'd like to point out that this information was published very 
prominently in the March 2009 issue of The Kingbird, Volume 59, pages 74-77. 
Both Tom Johnson in his Finger Lakes quarterly report and Andy Guthrie, in his 
statewide Highlights of the Season essay (page 48 of the same issue) refer to 
the record as a Regional high count, meaning a maximum for NYSOA's Region 3 
(Finger Lakes). I would guess that they stopped short of calling it a statewide 
maximum because they wanted to check records from other Regions carefully first.

In this regard, Kevin is right that eBird has not scratched the surface of 20th 
Century (or earlier) ornithological history, and he describes well the 
publications that form the backbone of New York State ornithological knowledge. 
Someone wishing to research the history of records of a particular species in 
NYS must, at a minimum, check the following sources: Bull 1974, Levine 1998, 
and The Kingbird Volumes 1 through present.

The Kingbird includes at least three categories of data review and analysis: 
(a) individual records vetted by expert Regional editors in their quarterly 
reports; (b) review of some particularly unusual records by the NYS Avian 
Records Committee in their statewide annual reports (Ross's Goose reports were 
reviewed by NYSARC through 2004, but not since); and (c) dedicated articles 
assessing all potential sources of data, and evaluating these according to 
explicitly stated criteria (John recently performed this service in his review 
of vagrant hummingbirds in the June 2010 issue of The Kingbird).

Thanks to the hard work of many people at the New York State Ornithological 
Association, The Kingbird is now available in a searchable online archive 
(except for the most recent two volumes), as noted recently by Berna, in 
reference to a query regarding unusual dates for Blue-winged Teal, at:

http://nybirds.org/KBsearch.htm

What about eBird? This is an immensely powerful and useful tool, and I would 
suggest using it to guide your searches through the three primary sources named 
above. But I would never use it as the source for a noteworthy record not 
otherwise corroborated by a primary source. If a noteworthy report is to be 
accepted by others, it ought to be treated as noteworthy--beginning with the 
observer! In my experience, eBird's lurkers (= exceptional records not 
otherwise reported to the broader ornithological community) are too often 
erroneous to simply accept them all at face value and include them in scholarly 
reviews of, for instance, wintering Blue-winged Teal or Ross's Goose expansion. 
The solution is easy: if you see something unusual that you'd like other people 
to take seriously, take it seriously yourself! Don't just click a box on an 
online checklist; take a moment to explain it to the people you'd like to 
accept it.

To close, I'd suggest that the extraordinary recent events in Orange County 
deserve a prominent platform and could be the catalyst for a critical 
re-assessment of the status of Ross's Goose in New York State. (Hint: deadline 
for text to be included in the fall 2011 issue, covering the spring 2011 
season, is 15 July.)

RE: [nysbirds-l] Orange County Geese

2011-03-09 Thread Shaibal Mitra
If I understand the recent reports from Orange correctly, the number of Ross's 
Geese present 6-7 Mar was at least 8, and possibly 10 or more.

Monday's report from Andy Egan specified 5 white adults
Sunday's report from Tom Burke, John Haas, and others specified 2 white ads, 2 
white imms and a blue ad

If one assumes that both white ads from Sunday were among the 5 such birds seen 
Monday, then the total would be 8; if it could be shown that the bumpy-headed 
white ad from Sunday was NOT among the 5 white ads seen Monday, then the total 
would be at least 9.

[nysbirds-l] Hybrid Tufted Duck x scaup Massapequa Lake, Nassau Co.

2011-03-12 Thread Shaibal Mitra
Shortly before dusk this evening, Patricia Lindsay and I observed an apparent 
hybrid Tufted Duck x scaup hybrid drake with a small group of Lesser Scaup at 
Massapequa Lake, Nassau County, LI.

The bird showed a top-knot, like an exaggerated version of a Lesser Scaup's 
hind-crown notch; much darker (but not black) back than a scaup's--but 
apparently only on the left side of its body (right side of back more 
scaup-like); and a black breast that extended a bit farther rearward onto the 
flanks than a scaup's (at least on the left side).

[nysbirds-l] Historical Status of Muskrat on LI

2011-03-14 Thread Shaibal Mitra
Paul F. Connor (1971, The Mammals of Long Island, New York, Bulletin 416 NYS 
Museum and Science Service) describes the Muskrat's historical ubiquity 
throughout Long Island's salt and brackish marshes and all manner of freshwater 
wetlands. He specifically mentions that, as of his writing, they were still 
present in Brooklyn (Jamaica Bay) and Queens, and on Staten Island; eastward 
they extend to Montauk Point, Orient Point, Shelter Island, and Gardiners 
Island.

He also mentions reductions in their populations owing to the destruction of 
marshes, and cites an earlier source who noted that during the winter of 1919, 
over a thousand dollars worth of the furs were harvested from the salt marshes 
and creeks (Flushing Meadows area in Queens) that later became the site of the 
1939 World's Fair.

They are still very numerous on Staten Island today, as proven by the seemingly 
very large numbers of road-killed animals I see there.

[nysbirds-l] LI Birds: Black-headed Gull, Waterfowl Migration+

2011-03-28 Thread Shaibal Mitra
Pat and I counted migrating waterfowl from 7:25-8:25 yesterday morning (27 Mar) 
at Main Beach, East Hampton, Suffolk Co. The main flight was from west to east, 
but White-winged Scoters and some others were moving from east to west.

Black Scoter was the most numerous species (277), and most of the 475 distant, 
unidentified scoters we saw were probably also this species. Also notable were 
93 White-winged Scoters (seemingly scarce this season), 151 Red-throated Loons, 
49 Northern Gannets, and 32 Razorbills.

The vast sea duckage present at Montauk Pt this season appeared to have been 
augmented yesterday by additional thousands of Black Scoters. Different 
observers have been coming up with very disparate estimates of the actual 
numbers involved there, and I've been told that Pat's and my numbers have been 
low. For what it's worth, we've estimated ca. 15,000 Black Scoters there on 
several visits earlier this season (compared to ca. 20,000 Surf Scoter, 5,000 
Common Eider, and 1,000 WW Scoter), whereas yesterday I thought BLSC numbers 
were approximately twice what we've been seeing.

Consistent with the impression of swelling numbers of Black Scoter were 2,700 
at nearby Ditch Plains, in a dense flock close inshore and in full song. 209 
Ring-billed Gulls were surface gleaning here, along with 17 Bonaparte's Gulls 
and one SY Black-headed Gull.

We saw single Turkey Vultures in Montauk and Napeague, Merlins at Montauk and 
Hook Pond, Great Egrets in Napeague and Water Mill, and Lesser Black-backed 
Gulls at Napeague and Mecox Bay.

Following up Carl Starace's tip, we visited Terrell River County Park for the 
first time and were impressed by a flock of 105 Green-winged Teal plus three 
Northern Shovelers. The greenbrier thickets at this park look superb for 
wintering half-hardies; although we didn't have time to work them, we 
encountered a Hermit Thrush along the trail that looked pretty spry after a 
long, snowy winter--as did a Gray Catbird that flew across Further Lane earlier 
in the day.

[nysbirds-l] New Bird Species for New York State--Which Will Be Next?

2011-03-28 Thread Shaibal Mitra
The question of new additions to the state list, a perennially popular topic of 
conversation among birders, was recently worked up in great detail by Doug 
Gochfeld and a team of 24 of New York's most active birders.

Predictions of species to be added to the New York State Checklist--v. 4.0 
was published in the December 2010 issue of The Kingbird, the quarterly journal 
of the New York State Ornithological Association, and is now available online 
at NYSOA's website:

http://www.nybirds.org/Publications/KingbirdTOCs.htm#Vol60No4

All the contents of The Kingbird are uploaded to a searchable online archive 
two years after print publication, but sample articles are featured on the 
website from time to time, and in this case, we'd like to make available a 
corrected version of Table 1, which was misprinted in the print issue. A 
formatted version of Table 1 can be printed by opening the article and printing 
page 7.

With the permission of the list-owner, I'd like to take this opportunity to 
share a few more items of potential interest:

Each issue of The Kingbird includes a color photo gallery; a statewide 
Highlights of the Season summary of the past season's bird data; and 
quarterly seasonal reports of bird records from across NYS, written by expert 
Regional Editors representing ten geographic regions (1-Niagara Frontier, 
2-Genesee, 3-Finger Lakes, 4-Susquehanna, 5-Oneida Lake Basin, 6-St. Lawrence, 
7-Adirondack-Champlain,  8-Hudson-Mohawk, 9-Hudson-Delaware, and 10-Marine).

The 2009 Annual Report of the New York State Avian Records Committee (NYSARC) 
will be arriving shortly in NYSOA members' mailboxes, with the March 2011 issue 
of The Kingbird. NYSARC is one of NYSOA's committees and is charged with 
reviewing and archiving documentation of rare bird records in NYS and with 
maintaining the official Checklist of NYS Birds. NYSARC's authoritative and 
much anticipated 2009 Annual Report is also already freely available at NYSOA's 
website right now:

http://www.nybirds.org/index.html

Among the articles slated for publication in upcoming issues of The Kingbird 
are a report on a highly successful nest box management program for American 
Kestrels in northern NYS by Mark Manske; a paper on Red Crossbill call-types by 
boreal finch expert Matt Young; a historical analysis of Mute Swan 
introductions in New York State by Chelsea Teale; and an update from NYSARC 
detailing several newly vetted additions to the NYS Checklist (hint: Doug's 
panel made some very good predictions!).

Sincerely,

Shai Mitra

RE: [nysbirds-l] 38 Snowy Egret/Jamaica Bay WR

2011-04-10 Thread Shaibal Mitra
This early-mid April period seems to be when Gannets are most likely to 
penetrate inshore waters, in our bays and sounds, where they are normally rare. 
John and Kirsten's observations at Jamaica Bay are really very unusual. My 
companions and i had some similar experiences yesterday--a Gannet north of 
Hicks Island, in Napeague Bay, and then 26 Gannets resting on the waters of 
Shinnecock Bay, north of the main sandbar there. I can't ever recall seeing so 
many in there. Today, Marc Brody mentioned seeing them inside Jones Inlet.

This time of year seems to be when the Gannets push their boundaries--

https://picasaweb.google.com/tixbirdz/ThereYouAre#5375001706807305570

--and I wonder if they are tracking a migratory prey species, like one of the

 our most interesting sighting of the day however, was that of two adult

I drove to Hempstead Lake State Park (HLSP) this morning by way of the barrier 
beach, which was fogged in with very few birds to boot. At HLSP there were 
Yellow-rumped, Black  White, Parula, Black-throated Green, Palm, Prairie, and 
Yellow Warblers. Sparrows included Swamp, Chipping and the regular 
White-throats and Song Sparrows. A few Blue-headed Vireos were present as well 
as Ruby-crowned Kinglets and Gnatcatchers.

Observed by Others at HLSP: Yellow-throated Vireo, Chimney Swift by Joe 
Viglietta and mob.

At West End later that morning the fog had lifted but things were relatively 
quiet.  A few Yellow-rumps and Ruby-crowned Kinglets were in the median. The 
highlight was a flyby Eastern Kingbird. Merlins have been present in small 
numbers along the beach for the past few days.

Observed by Others at West End: Gull-billed Tern in the early afternoon by Joan 
Quinlan.

At Connetquot River State Park (CRSP) in the afternoon I missed the 
Yellow-throated Warbler seen in the late morning. Pine Warblers (18) and 
Gnatcatchers (10) were present in good numbers and another Eastern Kingbird was 
singing on the west side of Deep Water Pond. Besides Pine Warblers, the only 
other warblers observed were Yellow and Black  White. All three warblers (not

RE: [nysbirds-l] Central Park, NYC 4/25 (incl. YTWA report much, much more, Varied Thrush also still there...)

2011-04-25 Thread Shaibal Mitra
From 1996 through 1999, in the course of near-constant effort banding at the 
Fire Island Lighthouse, I captured 11 northbound Yellow-bellied Flycatchers, 
on dates ranging from 19 May through 13 June. Four of these 11 were captured 
19-20 May 1996, during one of coastal NY's largest spring landbird flights in 
recent decades, whereas the other seven were captured on later spring dates. 
Thus I would tend to agree with Scott's perception of this species as a very 
late spring migrant--much later than Least, and similar in overall timing to 
Willow and Alder.

It should be noted that Least and Willow breed in southern NYS, and in large 
numbers at much more southerly latitudes, so it is not terribly surprising to 
see a few of these species here toward the early end of their respective 
passage distributions: e.g., a Least Flycatcher or two at the end of April, vs. 
the median date of 12 May for migrant Leasts at Fire Island; or an early Willow 
setting up territory around 10 May, vs. the median date of 1 June for migrant 
Willow/Alders at Fire Island.

Yellow-bellied does not breed anywhere south of NYS (maybe a few in the 
Poconos), thus I would tend to think that the dates of territory occupancy in 
northern New York would follow closely upon the dates of migratory arrival in 
the New York City area.

I may respond on-list to Scott Haber's thoughful response to an early Empidonax

am interested to try and look up records from the region of this and other 
Empidonax species, including any available specimen  banding records as well 
as any video-audio-photo records, and sight reports in the early season, 
particularly any before May 1st.  This is not the first Yellow-bellied 
Flycatcher I have seen  heard singing .or calling in New York City in the 
beginning stages of the spring push of neotropical-wintering migrants 9as 
opposed to shorter-distance migrant species that may primarily overwinter in 
the southern U.S. or nearby, such as Pine Warbler  any number of others that 
appear as early as March in our area almost each spring - I do not agree that 
Yellow-bellied is among the last and while I respect the writing of John M.C. 
Peterson as regards breeding information for New York, I do not think it 
reflects accurately on the status of migrants in the southern section of the 
state, with regards to this species of Empidonax. It would be interesting to 
read and hear from any others who have looked as well as listened carefully to 
the Empidonax group here in NY and nearby states.

[nysbirds-l] LI Birds: Black Skimmers and Loon Migration

2011-04-28 Thread Shaibal Mitra
Three Black Skimmers flew across the Belt Parkway at Plumb Beach, Brooklyn at 
6:20 this morning.

At Robert Moses SP, southwestern Suffolk County, from 7:30-8:00 yesterday 
morning, I counted 74 Red-throated Loons migrating from west to east over the 
ocean. Three of these were in full breeding plumage. I also noticed a strong 
flight of Common Loons for the first time this season, with 13 birds in mostly 
breeding plumage flying eastward. One of these cut inland and flew up the Fire 
Inlet, as many Common Loons tend to do at this time of year.

More unusual was a flock of 25 Black Scoters migrating up the inlet (modest 
numbers of all three scoters, plus Gannets, Bonaparte's Gulls, and Forster's 
Terns were moving eastward over the ocean).

[nysbirds-l] LI Birds: Early Seabirds++

2011-05-15 Thread Shaibal Mitra
Seabirds and shorebirds made a big showing on LI this weekend.

During a Saturday afternoon seawatch at Cupsogue, near Moriches Inlet, Patricia 
Lindsay and I were joined at times by Richard Kaskan, Mike Higgiston, and 
Eileen Schwinn. Highlights were our earliest ever Wilson's Storm-Petrels (11) 
and a first summer Black-legged Kittiwake; five Roseate Terns and 27 Black 
Skimmers were present on the flats. Later at Shinnecock Inlet we were amazed to 
see at least 70 WISPs feeding over a patch of water southwest of the inlet 
mouth. A breeding-plumaged Horned Grebe was also noteworthy on Shinnecock Bay.

This morning at Robert Moses SP, we observed a very nice movement of seabirds 
from 6:40-8:40:

2 Sooty Shearwaters
144 Wilson's Storm-Petrels
605 Northern Gannets (almost all immature)
46 Common Loons
17 Red-throated Loons
2 Lesser Black-backed Gulls (first summer  third summer)
1 Roseate Tern
45 Least Terns
3 Black Terns (breeding plumage)

Other observers at Robert Moses this morning were Ken and Sue Feustel, Gail 
Benson, Tom Burke, and Bob Shriber. Later, Pat and i searched unsuccessfully 
for the Kentucky Warbler at Jamaica Bay and enjoyed an odd chorus of 16 species 
of warblers in the rain at Forest Park with Karlo Mirth. We reconvened with 
Tom, Gail, and Bob (and met up with many others) at Jones Beach in the pm, to 
ogle the White-winged Dove found by Doug Futuyma and Andrew Baksh. Additional

Seabirds and shorebirds made a big showing on LI this weekend.

During a Saturday afternoon seawatch at Cupsogue, near Moriches Inlet, Patricia 
Lindsay and I were joined at times by Richard Kaskan, Mike Higgiston, and 
Eileen Schwinn. Highlights were our earliest ever Wilson's Storm-Petrels (11) 
and a first summer Black-legged Kittiwake; five Roseate Terns and 27 Black 
Skimmers were present on the flats. Later at Shinnecock Inlet we were amazed to 
see at least 70 WISPs feeding over a patch of water southwest of the inlet 
mouth. A breeding-plumaged Horned Grebe was also noteworthy on Shinnecock Bay.

This morning at Robert Moses SP, we observed a very nice movement of seabirds 
from 6:40-8:40:

2 Sooty Shearwaters
144 Wilson's Storm-Petrels
605 Northern Gannets (almost all immature)
46 Common Loons
17 Red-throated Loons
2 Lesser Black-backed Gulls (first summer  third summer)
1 Roseate Tern
45 Least Terns
3 Black Terns (breeding plumage)
1 Parasitic Jaeger (adult light morph)

[nysbirds-l] LBB Gull Influx incl possible Yellow-legged Gull

2011-05-17 Thread Shaibal Mitra
As indicated by  reports from many observers this past weekend, the spring 
flight of immature Lesser Black-backed Gulls is in full swing on Long Island 
(adults have presumably moved through already).

The stormy weather yesterday and today seems to have driven even more birds 
ashore--as suggested by Doug Gochfeld's report from Brooklyn and my own 
observation of at least eight individuals in southwestern Suffolk County 
yesterday.

Most of the birds we've been seeing are first-summer birds (fledged last summer 
= SY), a plumage that is unfamiliar to many observers. For those interested in 
looking for these birds, a series of photos of LBBGs, organized by age and 
date, can be seen here:

https://picasaweb.google.com/tixbirdz/LesserBlackBackedGullsOnLongIsland#

My main reason for posting this message is to draw attention to the possible 
occurrence of Yellow-legged Gull, a taxon very similar to LBBG and also to 
European Herring Gulls. Last year on 4 Jun I photographed a bird at Robert 
Moses SP that closely resembles a Yellow-legged Gull:

https://picasaweb.google.com/tixbirdz/PossibleYellowLeggedGullOnLongIsland6409#

One of seven birds at this same site yesterday reminded me quite strongly of 
that bird, being a big, beady-eyed brute compared to typical LBBGs. This bird 
is labeled LBBG 3 in the sequence near the start of this album:

https://picasaweb.google.com/tixbirdz/LongIslandSpring2011#

This morning Pat Lindsay reported two LBBGs and an Iceland Gull at RMSP. It 
would be interesting to know how many are present elsewhere along the coast.

RE: [nysbirds-l] Jones Beach fall out

2011-05-25 Thread Shaibal Mitra
The yellowthroats and Ovenbirds were surely regular migrants heading north (the 
date for my Ovenbird max at Fire Island was as late as 19 May). For abundant 
passerine migrants, I doubt that floaters contribute significantly to maximum 
counts.

Many common migrants max out much later than people suspect (Red-eyed Vireo and 
American Redstart are good examples of birds that probably haven't peaked yet 
this year). Even your Hooded Warbler yesterday was only slightly tardy for 
arrival in southern New England. At my old study site in Rhode Island's Great 
Swamp, which is about as far northeast as Hooded Warblers breed at high 
densities, the number of males on territory tended not to max out until around 
20-25 May.

Part of the reason that these very heavy late spring movements are 
under-detected is probably that birders tend to under-count common species, 
particularly those that also breed locally. Another reason seems to be that the 
pace of spring migration accelerates as the season advances, so individual 
birds might be making longer flights and/or briefer stopovers in our migrant 
traps now, as compared to late April/early May.

In the past, I've heard the term floater used. This applies to maybe first 
year individuals or others that, for whatever reason, have not yet established 
a territory. This would likely apply to many species. One of the things in 
Alley that tipped me off that birds had moved was the number of Ovenbirds I 
heard singing. This is an early migrant and the Queens parks had emptied out on 
them prior to yesterday. A couple of Baltimore Orioles were among the birds at 
Jones Beach. They arrive early, for the most part, and I don't believe nest on 
the beach. And of course, Hooded Warbler is not something to be expected to 
still be in migration (and this was a male). The floater phenomenon might be 
especially evident in generally southern breeders (because they are the first 
to complete their migrations). As an example, I remember a Swainson's Warbler 
years ago that appeared at Forest Park right about this time. This could 
explain the later moving Common Yellowthroats -- or they could be the 
northernmost breeders just timing their migration appropriately.

Remnants of yesterday's coastal flight were still evident during a brief visit 
to Robert Moses SP this morning.

Most interesting to me were large numbers of passage-migrant Common 
Yellowthroats bouncing westward and getting up into the pines and other 
settings neglected by the local breeders. In retrospect, I probably only saw 
about seven undoubted migrant yellowthroats during a twenty minute walk (during 
which I probably saw or heard a comparable number of local breeders), but given 
the mechanics of bird detection on the barrier-beach, there must have been 
hundreds of migrant yellowthroats navigating the puckerbrush today (our 
single-day max at the nearby Fire Island Lighthouse was 99 banded on 22 May 
1999).

Given that the species has been back for about a month and is an abundant and 
ubiquitous breeder across the state, this kind of flight probably wouldn't be 
discernible in most settings. I wonder whether even a tool as powerful as eBird 
is likely to detect a major flight of this kind--or the counter-intuitive fact 
that Common Yellowthroat migration in southeastern NYS peaks as late as the 
fourth week of May?

There was a bit of a fall out this morning at Jones Beach West End. Not 
overwhelming, but you didn’t have to look hard for the next bird. Most notable 
were Hooded, Wilson's, Tennessee, and Blackburnian Warblers. Most numerous were 
Blackpoll, Magnolia, and Parula. I only noticed this when reviewing pictures. 
One of the Parulas was missing an eye. It's made it a long way like that. Also 
seen were a few diurnal migrants such as Ruby-throated Hummingbird, Eastern 
Kingbird, Cedar Waxwing, and Bobolink. It's reassuring to find that a warm 
front - fog combo can still produce on the beach in spring.

Considering the above, the Queens parks were disappointing in the afternoon 
(although a very early morning check of Alley convinced me that there was 
worthwhile migrant activity

[nysbirds-l] LI Birds: Black-necked Stilts, Blue Grosbeak+

2011-05-28 Thread Shaibal Mitra
Two Black-necked Stilts mentioned on last night's New York RBA were present 
this morning at Sebonac Inlet in Southampton, Suffolk County. The stilts were 
feeding around the southwestern tip of the gravel island directly east of the 
north end of Sebonac Inlet Road, sometimes wandering behind the spit and into a 
sheltered cove. Even there they could be seen by walking south on Sebonac Inlet 
Rd and looking northeast.

Earlier in the morning, Patricia Lindsay and I made our traditional census of 
the woodland birds at East Hampton's Grace Estate. Many species have been 
declining here in recent years, but we were unpleasantly shocked to find not a 
single Wood Thrush or Veery and just three Ovenbirds. American Redstarts were 
more numerous than usual, and a Yellow-throated Vireo was perhaps the most 
notable species. At nearby Cedar Pt, the terns seem just to be getting started, 
but we found more Redstarts and enjoyed a pair of very cooperative 
Yellow-billed Cuckoos as we ate breakfast.

At the Rte 51 DEC bikepath, in Eastport, Suffolk County, we ran into John 
Gluth, who had earlier seen the Blue Grosbeak near the north end of the 
bikepath, but dipped on the previously reported Yellow-throated Warbler in 
nearby Hunters Garden. After a long vigil, I spied the bird perched on the 
fence that borders the agricultural fields west of the bikepath shrublands, but 
it flew north and vanished before Pat and John could get on it. A longer vigil 
yielded one bout of song, but no more views.

Shorebird numbers were way down at Moriches Inlet, compared to last weekend, 
with the vast majority of Sanderlings, Dunlin, and Ruddy Turnstones apparently 
having moved on. Red Knots were still numerous (134 between Pikes Beach and 
Cupsogue), and many very fine looking Black-bellied Plovers were still there. 
Notable terns included a breeding-plumaged Black Tern, at least eight Roseate 
Terns, and my first sub-adult Common Terns of the year: one each first- and 
second-summer.

Photos of some of these birds can be seen at:

Hi James,

I can't say that I've found Canada Warblers breeding in Harriman specifically, 
but they breed readily at a similar latitude (and probably at even lower 
elevation) in southern Rhode Island, in red maple swamps along the interior 
edge of the Charlestown Moraine (e.g, in numbers at the Great Swamp WMA, where 
I heard one just this morning). There are even a few breeding records from red 
maple swamps in central Long Island (e.g., Connetquot River SP in Oakdale and 
Maple Swamp in Flanders):

[nysbirds-l] Possible Siberian Common Tern (S. h. longipennis) on Long Island

2011-06-27 Thread Shaibal Mitra
A second-summer type Common Tern present at Cupsogue, just east of Moriches 
Inlet, last weekend (25-26 June) resembled the Siberian subspecies of Common 
Tern (Sterna hirundo longipennis):

Bill black, with a slight red tinge
Legs dark reddish-black
Ventral body deeply gray, especially for a second-summer type individual
Wings appeared relatively long both at rest and in flight

Its wingtip pattern also differed from the typical summer pattern of local 
Common Terns in that all the primaries (except perhaps p10) appeared uniformly 
fresh and pale, but it is not very unusual for non-adults to vary in this 
regard.

In my experience, however, it is extremely rare to see such dark legs on any 
early summer Common Tern (even first summer birds), and it is also extremely 
rare to see an all-dark bill in combination with deeply gray underparts, at 
least prior to very late summer.

Photos of this bird can be seen at:

https://picasaweb.google.com/tixbirdz/PossibleSiberianCommonTernSHLongipennisOnLongIslandNY

Some representative photos of second-summer type Common Terns can be seen at:

https://picasaweb.google.com/tixbirdz/CommonTernsOnLongIsland#

I've never seen longipennis in its core range and am unfamiliar with how to 
assess other published characters, such as its whiter inner rectrices and 
subtly different tertials, but the photos might help here (even its 
second-to-outermost rectrices appeared less extensively dark in the field than 
in many local Common Terns).

Longipennis is said to have a shorter bill than hirundo, but this bird's bill 
looked pretty similar in size to those of local birds.

I'm calling this bird a second-summer type because its forehead and its gray 
underbody were mottled to varying degrees with white. I first noticed it on 
Saturday but I was not able to get good photos. It was present again on Sunday 
and studied by at least 19 observers.

RE:[nysbirds-l] Possible Siberian Common Tern (S. h. longipennis) on Long Island

2011-06-28 Thread Shaibal Mitra
Thanks to everyone who has commented to me about this bird so far--your 
contributions are very welcome.

Julian Hough sent me the following, with permission to post to the list:

I just recently saw photos of a bird at Minsmere, Suffolk, UK of a probable 
longipennis Common Tern. A striking looking bird, this one with a slightly 
shorter bill, but I agree that in the field their bills look similar in length 
to hirundo. Longipennis records from Europe were non-existent until recently. 
There was a recent record from the Black Sea coast of Turkey last (?) spring 
which was the first record, but by coincidence I and several others saw three 
apparent adult longipennis in the same area of Turkey back in ‘89.  The 
significance of that record is just being realized with the report of the 
recent Turkish individual and if accepted, would pre-date that occurrence by 2 
decades!
The bill color and extensive grey suffusion to the underparts and blackish legs 
of your bird all seem to fit with the descriptions of longipennis. I have seen 
longipennis in China and although I’ve not studied them ad nauseum, I agree 
that your bird and the UK bird are good candidates. The birds I recall from 
China had a darker trailing edge to the underwing, along the inner secondaries, 
that seemed to stand out more than on hirundo, although this could be down to 
lighting. I’ll have to check notes, but I think I recall some birds also showed 
some red at the base of their bills? I wasn’t aware of the tail pattern 
differences. The pitfalls are those dark-billed Common Terns, but they 
typically show reddish feet and the dark-billed birds are often the whitest 
below due to wear. It would be interesting to know what the status is of this 
race in the US since it may help form more of a pattern and help with their 
separation from similar-looking darker-billed hirundo. I think also Mike 
O’Brien had a similar bird at Stone Harbor point, NJ several years ago. A cool 
set of shots!

Subject: [nysbirds-l] Possible Siberian Common Tern (S. h. longipennis) on Long 
Island

A second-summer type Common Tern present at Cupsogue, just east of Moriches 
Inlet, last weekend (25-26 June) resembled the Siberian subspecies of Common 
Tern (Sterna hirundo longipennis):

Bill black, with a slight red tinge
Legs dark reddish-black
Ventral body deeply gray, especially for a second-summer type individual
Wings appeared relatively long both at rest and in flight

Its wingtip pattern also differed from the typical summer pattern of local 
Common Terns in that all the primaries (except perhaps p10) appeared uniformly 
fresh and pale, but it is not very unusual for non-adults to vary in this 
regard.

In my experience, however, it is extremely rare to see such dark legs on any 
early summer Common Tern (even first summer birds), and it is also extremely 
rare to see an all-dark bill in combination with deeply gray underparts, at 
least prior to very late summer.

Photos of this bird can be seen at:

https://picasaweb.google.com/tixbirdz/PossibleSiberianCommonTernSHLongipennisOnLongIslandNY

Some representative photos of second-summer type Common Terns can be seen at:

https://picasaweb.google.com/tixbirdz/CommonTernsOnLongIsland#

I've never seen longipennis in its core range and am unfamiliar with how to 
assess other published characters, such as its whiter inner rectrices and 
subtly different tertials, but the photos might help here (even its 
second-to-outermost rectrices appeared less extensively dark in the field than 
in many local Common Terns).

Longipennis is said to have a shorter bill than hirundo, but this bird's bill 
looked pretty similar in size to those of local birds.

I'm calling this bird a second-summer type because its forehead and its gray 
underbody were mottled to varying degrees with white. I first noticed it on 
Saturday but I was not able to get good photos. It was present again on Sunday 
and studied by at least 19 observers.

[nysbirds-l] Cupsogue Marathon!

2011-07-03 Thread Shaibal Mitra
A first-summer Arctic Tern was present at Cupsogue from 9:00-9:15 this morning, 
a nice reward for Richard Fried and me, just prior to high tide. A number of 
other birders had been seawatching at this time, counting upwards of 80 Cory's 
Shearwaters, 3 Wilson's Storm-Petrels, a distant jaeger (probably Parasitic), 
15 Northern Gannets, and several Lesser Black-backed Gulls. These folks were 
able to scope the Arctic Tern from afar, but it vanished quickly, as they so 
often do. A few photos can be seen at:

https://picasaweb.google.com/tixbirdz/LongIslandSummer2011

https://picasaweb.google.com/tixbirdz/LongIslandSummer2011To my eye, this was 
the fourth individual Arctic Tern here this year, its head pattern and tail 
streamers differing from one seen on 15 Jun and two seen on 29 Jun (one of 
which was superbly photographed the next day also).

Over the course of a very long day (I first stepped out on the marsh at 6:40 am 
and finished my third trip at 7:40 pm), at least three Royal, two Black, and 
three Roseate Terns were tallied, and lots of early fall shorebird migration 
was noted: many small flocks of Short-billed Dowitchers (including a 
high-breeding hendersoni picked out by Andy Guthrie), two Western Willets, and 
half a dozen each Lesser Yellowlegs and Least Sandpipers. The identity of a 
long-billed peep in first summer plumage was debated ad nauseum by some of the 
finest birding minds in New York State (despite my protests that they ought to 
just leave it alone!); a majority favored Western over Semi in the end.

The local Eastern Willets and Oystercatchers are ganging up now, with 63 of the 
former and 16 of the latter observed in tight flocks today. Two summering Brant 
appeared on the flats also.

[nysbirds-l] LI Birds: Arctic Tern+ at Cupsogue

2011-07-09 Thread Shaibal Mitra
A very large gathering of tern aficionados, including a young birders group, 
assembled at Cupsogue this morning and enjoyed great looks at a first-summer 
Arctic Tern. Photo forensics are ongoing to determine whether this bird is or 
isn't one of several similarly plumaged birds seen there earlier this summer. 
Also present were five Black Terns (we saw four), an adult Roseate Tern (not 
present when we arrived), and a Royal Tern at nearby Pikes Beach. There was 
also a notable influx of Least Terns, with three first-summer and two 
second-summer types among 50 adults on the flats. The local flock of immature 
Ring-billed Gulls increased to 35 and was joined by two first-summer Lesser 
Black-backed Gulls. Shorebird migration was evident throughout the morning, 
though not at high volume.

The most unusual sight, however, was a first-summer Roseate Tern. I've only 
knowingly seen this plumage a few times previously on Long Island.

This summer I've had many conversations with many readers of this list 
regarding the details of primary patterns in various tern species--marks that 
are poorly illustrated in guides but which are very useful in identification. I 
was very fortunate to capture an image of the portlandica Roseate with wings 
spread, just moments apart from a Common Tern in a similar posture:

[nysbirds-l] LI Birds: South Polar Skua+

2011-07-11 Thread Shaibal Mitra
Just before 7:00 this morning, Jeff Bolsinger and I observed a South Polar Skua 
from Robert Moses SP, near the western tip of Fire Island, Suffolk County, Long 
Island.

The bird appeared among 150 or more actively feeding shearwaters, all but a few 
of which were Cory's. (With Patricia Lindsay's help, we ultimately recorded two 
Greater and one Manx Shearwater, one Wilson's Storm-Petrel, six immature 
Northern Gannets, an immature Parasitic Jaeger, and modest numbers of Laughing 
Gulls and Common Terns.)

Jeff detected the skua flying from west to east in a very direct fashion. We 
readily recognized the bird as a stercorariid by its dark plumage, powerful 
flight, pointed wings, and white underwing flashes, but it took a few moments 
before we saw the bird in direct comparison with other birds.  As this was 
happening, we noted its uniformly dark plumage (lacking any discernible barring 
or streaking) and bold white upper-wing (as well as under-wing) flashes. 
Fortunately, the bird turned in and approached closer to us, coming into direct 
comparison with and dwarfing a Greater Shearwater, which appeared roughly half 
its size in terms of overall bulk. Next, we were briefly perplexed when a 
tern it was wrangling with turned the tables and started chasing it. It 
dawned on us that this other bird was actually a jaeger, and we were able to 
judge quite confidently that the jaeger was markedly smaller than adjacent 
large shearwaters, and that the latter were markedly smaller than the skua. As 
it wrangled with the tiny-looking jaeger, the skua's relatively broad wings and 
short tail were readily assessed.

Both skua and jaeger appeared to settle onto the water and vanished from view. 
This gave us hope that the skua would remain until Patricia Lindsay arrived, 
but, unfortunately, we never saw it again. The three of us did pick up the 
jaeger a little later, flying westward and giving good views of its structure, 
color, and barred underwing and tail coverts, indicative of an immature 
Parasitic Jaeger.

[nysbirds-l] Long Island Early Summer Larids--Wrap-up

2011-07-27 Thread Shaibal Mitra
As the coastal scene shifts into late summer mode, with southbound shorebirds 
moving through and newly fledged gulls and terns flocking up, it seems like a 
good time to take stock of early summer's teenage larid scene on Long Island.  
I offer this summary as an aid to NYSARC and others interested in enumerating 
records of New York State birds and would welcome comments concerning any 
errors or differences of interpretation. The summary focuses on situations 
where I thought that the birds’ individual identities were important, and it 
explains my rationale for concluding that June-July 2011 featured one Iceland 
Gull, two Glaucous Gulls, four Sandwich Terns, and five Arctic Terns on Long 
Island. Sub-adult gulls and terns are frequently individually identifiable 
through close study of head pattern, bill and leg color, and tail streamer 
length, and also via unique asymmetries and injuries.

I've selected photos to illustrate the features used to identify individual 
birds and presented them together at:

https://picasaweb.google.com/tixbirdz/LongIslandSummerLaridWrapup

Andrew Baksh, Gail Benson, Nick Bonomo, Patricia Lindsay, Donna Schulman, 
Eileen Schwinn, and Steve Walter generously shared images of some of these

birds, with special thanks to Bob Adamo, Seth Ausubel, Andrew Baksh, Rob Bate,

Iceland Gull
At least one seen Jones Beach to Robert Moses SP on a number of occasions

Glaucous GullTwo different birds.
Long-staying individual at Orient Pt with injured right leg, present at least 
through 20 Jun (SSM) and illustrated by photos from July 2010, January 2011, 
and June 2011.
A bird at Cupsogue mid Jul 2011 (Eileen Schwinn et al.) appears to be a 
different individual (whiter plumage and dark-looking eye suggest SY; no injury 
to right leg, whereas injured right leg of Orient Pt bird obvious under most 
circumstances).

Arctic TernFive different birds, only one seen on more than one day.
2011a 15 Jun Cupsogue (SSM et al.)Typical SY; rear crown flecked 
with black; dark mask of average breadth and diffuse; RR6 (outermost tail 
feathers) no longer than RR5 (nest to outermost); demonstrably different from 
2011b, 2011c, 2011d; arguably could be the same as 2011e (9 Jul) if RR6 still 
growing on 15 Jun, but facial pattern also subtly different; also these 
observations were separated by almost a month, with three other ARTE—but no 
sightings plausibly attributable this bird—in between.
2011b 29 Jun Cupsogue (Seth Ausubel, “Gamma Digitorum,” et al.)
Distinctive immature, SY or TY; plumage more advanced than in most SYs but less 
advanced than in most TYs; bill black as in SY, but legs slightly redder than 
usual for that age.
2011c 29 Jun Cupsogue (Seth Ausubel, “Gamma Digitorum,” et al.)
2011c 30 Jun Cupsogue (Steve Walter, Rob Bate, et al.)Typical SY; 
long tail streamers extending beyond wingtips at rest; white crown extended 
farther rearward than in other 2011 SYs; dark mask relatively narrow and neat; 
faint white arcs above eyes. Photo documentation of these characters strongly 
supports the identity of birds observed 29  30 Jun. To my knowledge, this is 
just the third example of an individual Arctic Tern persisting across dates 
among 40+ photo-documented birds on Long Island.
2011d 3 Jul Cupsogue (SSM, mob)Typical SY; outermost tail feather 
on right side (right R6) missing; rear crown flecked with black; dark mask 
relatively broad and diffuse.
2011e 9 Jul Cupsogue (Brent Bomkamp, Gail Benson, mob)Typical SY; 
rear crown flecked with black; dark mask narrow and diffuse; both outermost 
rectrices (RR6) present

Hi Shai,
I was wondering if you could post this update on the NY Birding List-serve for 
me.  Thanks.

8/2/11  Coney Is. Beach, Brooklyn, NY - Ed Hagen and I made the drive down from 
CT and were rewarded with great views of the Gray-headed Gull from 5:20 pm and 
for about an hour thereafter.  The bird was resting and foraging (on litter, 
food scraps) on the beach in the general vicinity of the man-made palm tree 
fountain just south of the foot of W. 12th St.  (near the Wonder Wheel ferris 
wheel).  It flew numerous times but stayed on this general section of the 
beach.  I and several of the 10-20 birders present obtained numerous photos.  
Then about 6:20 / 6:30 pm the Gray-hooded Gull took flight with a small flock 
of Laughing Gulls and apparently vanished.  Some birders who arrived just 
afterwards may have missed seeing it.  We departed about 7:15pm.  By the way, 
we couldn't find any street parking, so made use of the pay-lot ($10) on W. 
12th St., which was only two blocks to the beach.

RE: [nysbirds-l] GHGU location

To: NY BIRDS Cornell
Subject: [nysbirds-l] GHGU location

I am hoping someone can post directions to the Coney island bathhouse, from 
the LIE.   Thanx in advance Dan Furbish.

Step 1 is getting to the Belt Parkway.

From points north (e.g., Throgs Neck and Whitestone Bridges) and east (Queens, 
Nassau, and Suffolk Counties), I suggest googling directions from your 
starting point to JFK airport and using these as a basis for getting to the 
Belt Parkway.

2. From the Belt Parkway, take exit 7, Ocean Parkway, south toward the Aquarium.

Go south on Ocean Parkway as far as you can, then right (west) on Surf Ave.

3. The gull frequents the beachfront just south of Surf Ave, between the 
Aquarium (8th St, I think) and 15th St, a small road with lots of metered 
parking. If you can't find a space at 15th St, go back out onto Surf and look 
for meters to the east (people have reported finding parking of various kinds 
along Surf and at 12th and 10th Streets).

If you still have trouble (unlikely on a weekday), turn around and repeat the 
process. If you get frustrated, you can pay for safe parking at the aquarium.

4. Make note of what Street (e.g., 8th, or 12th, or 15th) you've parked near, 
walk out onto the boardwalk, then navigate to a point even with 12th St (three 
short blocks east of 15th or four short blocks west of the aquarium). You will 
see the Wonder Wheel behind you and a fountain on the beach side shaped like a 
palm tree. The gull likes this fountain and also perches on the yellow volley 
ball net poles nearby, or on the beach, or on the signs above the boardwalk 
businesses. When present, it is usually conspicuous, moving around among these 
spots but seldom wandering west of the big pier or east of the aquarium.

[nysbirds-l] LI Birds: Brown Pelicans, White Ibis+

2011-09-02 Thread Shaibal Mitra
When Pat and I pulled up at the Lake Montauk Inlet around 8:00 this morning, we 
were elated to see a juvenile Brown Pelican on the east jetty. Scoping further, 
Pat noticed an older individual on the west jetty, and I found a one year-old 
Great Cormorant, our first of the fall, near the first pelican. The juv pelican 
soon got up and began feeding inside the northern part of Lake Montauk. In the 
airspace above, we heard a few Dendroica zints and one Bobolink; more 
surprising was a late Orchard Oriole that dropped out of the sky, paused in a 
bayberry clump for a few seconds, then flew off to the east.

Montauk Pt was quiet in terms of birds, but it was a great pleasure to gaze 
upon the ocean again. A duo of yellowlegs, one of each species, were a curious 
sight as they flew eastward toward Block Island.

When we returned to the inlet around mid-day, both pelicans were together on 
the west jetty, but they were soon disturbed by people and flew into Lake 
Montauk.

The day started out feeling like fall but regressed back to summer. Several 
early migrant species showed notable reductions compared to recent days: Barn 
Swallows and Least Terns were scarce, and we saw just one each of Purple Martin 
and Bank Swallow. Black Terns also seemed fewer than during and immediately 
after Irene: we saw two at Deep Hollow, about 60 at Napeague Harbor, and just 3 
at Mecox Bay, whereas much larger numbers had been present at these places a 
few days ago.

Because we were afield all day without smart phone technology, it wasn't until 
4:30 that we learned of Jim Ash's White Ibis. We pulled up at Bridge Lane on 
Sagaponack Pond with Doug Futuyma around 5:00, and it took Pat's keen eye only 
a few moments to detect the ibis (rather distant and obscured by heat shimmer) 
along the southern edge of the ploughed field--joined at times by a Green Heron.

Photos of some of these bird can be seen at:

[nysbirds-l] LI Birds: Gulls feeding on ant swarms

2011-09-08 Thread Shaibal Mitra
While driving home along the Belt Parkway this evening I saw at least seven 
large swarms of gulls (mostly Laughing Gulls, but also many Ring-billed and and 
a few Herring), apparently feeding on flying ants. This phenomenon is expected 
at this time of year in coastal Long Island, e.g.,

http://www.nybirds.org/KBsearch/y1977v27n2/y1977v27n2p87-88lauro.pdf

--but it is still very interesting, for instance, how do different colonies 
come to swarm at precisely the same time?

The swarms I saw tonight were at Plumb Beach, east of Gerritsen Inlet, 
Paerdegat Inlet, Pennsylvania Ave., Erskine St., and two sites in South Ozone 
Park.

I've posted a photo of an ant from a similar mass-swarming event along the Long 
Island shore a couple of years ago at:

[nysbirds-l] FW: Montauk Wheatear

2011-09-17 Thread Shaibal Mitra

I arrived at Deep Hollow around 3:30 and learned from Pat Lindsay and Joan 
Quinlan that the bird had vanished about an hour earlier. They and Nick Laviola 
were trying to re-find it from the path along the east side of the Deep Hollow 
Ranch, so I decided to look from the ridge on the Teddy Roosevelt side. Walking 
north along the fence line, I found the bird perched on a fence-post a bit 
beyond the top of the ridge. The bird remained here for about half an hour, 
sometimes dropping down to the ground and rocks to the left (west). Around 4:15 
it flew east and out of sight. Our last glimpse of it suggested that it was 
going to land pretty soon (rather than make a bid for the Azores). It probably 
landed in one of the north pastures. I would suggest trying the TR fence line 
first, then the trail along the east side of Deep Hollow if that fails. The 
horse farm on the south side of the road is, of course, worth checking--both as 
a suitable site for this bird, and on general birding principle.
