[nfc-l] Etna, NY: Dickcissel @ 9:07pm

[Chris Tessaglia-Hymes]

The night flight overnight last night (9/15-9/16) was amazing to hear. Near
constant flight calls. Wave after wave. Species composition or, at least,
prevalence changed throughout the night.

Early in the evening (I started listening and recording at 8pm), there was
a heavy movement of Rose-breasted Grosbeaks, with various warbler flight
calls throughout. There were also occasional Green Heron and Swainson's
Thrush flight notes.

By mid-night flight, there were very frequent Swainson's Thrush and
Gray-cheeked Thrush calls, as well as regular Chestnut-sided Warbler and
Black-throated Blue Warbler flight calls. Occasional American Redstart,
Ovenbird, and a handful of White-throated Sparrows.

What was also interesting was this: I started out recording with my
Evans-style flowerpot (with the knowles element), acquiring using Raven Pro
on my Macbook Pro. Around 2am, I awoke to an acoustic spectacle that I felt
needed to be record with a slightly higher fidelity setup. I place two Rode
microphones out on the rooftop and began recording simultaneously with my
Zoom H4n recorder. With the latter setup, I was careful to arrange the
microphones (and my earbud headphones) such that my right ear was listening
to the ENE and my left ear was listening to the WNW. Interestingly, nearly *
all* thrushes heard calling were apparently moving in the distance to the
ENE. I did not notice many at all that were as loud heard calling out of
the WNW. This makes me wonder if it is at all possible that most of the
birds I heard were moving down the valley well to my East.

In any case, this was a very memorable night flight.

Attached is a Dickcissel that called at about 9:07 last night (I'm browsing
through sounds right now - Flowerpot recording).

[nfc-l] Migration Tonight: Northeast US

[Chris Tessaglia-Hymes]

Just a heads-up: tonight (and probably tomorrow night) there is a heavy
migration of birds moving overhead.

Many warblers, some sparrows, and a good movement of Green Herons (at
least, here over Etna, NY).

Hope folks can get out and listen!

Sincerely,
Chris T-H

RE: [nfc-l] Unknown

[Chris Tessaglia-Hymes]

Bill,

 

This has a similar quality and duration to that of the Wilson's Snipe
grating alarm call. Other than that, perhaps another shorebird species?
Thoughts?

 

Sincerely,
Chris T-H

[nfc-l] FW: [GeneseeBirds-L] News of note: massive Blackpoll Warbler kill in West Virginia

[Chris Tessaglia-Hymes]

Does anyone know anything about this Warbler kill in West Virginia? Could
this have been prevented with a NFC detection system or was it simply the
fact that structures are there (moving or not)? Was it aviation
lighting-type that contributed (strobe/non-strobe/red/white, etc.)?

 

Would appreciate any input (on-list is okay).

 

Thanks!


Sincerely,
Chris T-H

Subject: [GeneseeBirds-L] News of note: massive Blackpoll Warbler kill in
West Virginia

 


The abundant Blackpoll Warblers migrating o'er the lakefront this year made
big news both here and in other regions.  Betsy Brooks reported "It has been
a record-breaking Blackpoll Warbler season at BBBO ...  today we banded
another 21, bringing our total this fall to an amazing 705.  The previous
high for fall had been 383 banded in 2008. The numbers appeared to be
slowing down around Oct 4 but began building again on Friday Oct 7."
(listerv, Oct. 10th).

 

Tragically, it seems a massive kill of these warbler happened at a wind farm
in West Virginia. 

 

While I have not vetted this kill information from primary sources, this is
copied by Kimberly Kaufman, exec. director of Black Swamp Bird Observatory
on her Facebook wall, and was indeed on the PA listserv.

 

How senseless. Birders need to be on top of the wind farm issue and help
them get properly sited away from major migration corridors.

 

My heart goes out the banders who may have held some of these warblers in
their hands and wished them well on their migration.

Blackpoll Warblers killed in West Virginia 


Date: Thu, 27 Oct 2011 08:08:00 -0400A massive kill at AES Laurel Mtn wind
project in West Virginia 2 weeks ago: 500 - 600 migrating blackpoll warblers
were killed by wind turbines. This was confirmed by Craig Stihler of DNR in
Elkins, WV (304-###-0245) Blackpoll warblers are endangered in PA - we have
the southern-most breeding population. I hope we did not lose our nesting
blackpoll warblers in this tragic incident. From the PGC: "Blackpoll
warblers (Dendroica striata) are very rare and locally distributed nesting
birds in Pennsylvania. Confirmed nesting has been confined to the Dutch
Mountain wetlands in State Game Lands 57 of western Wyoming County. These
boreal conifer wetlands are part of the Important Bird Area #48. There have
been other reports of territorial blackpoll warblers elsewhere in northern
Pennsylvania, but no nesting confirmed." 

This tragic incident is further proof that our mountains should not be
developed for industrial wind energy. Laura JacksonEverettBedford County

[nfc-l] ADMIN: NFC-L Archives

[Chris Tessaglia-Hymes]

Good afternoon,

 

Executive Summary: 

 

Please try not to cross-post the same message to multiple eLists - in other
words, do not add multiple email Lists in the To: or Cc: fields of a new
message.

 

Instead, please generate a separate email message for each email List you
wish to post to. This will help prevent messages with duplicate Message ID's
from getting deleted by "smart" email-handling programs and, thus, help
prevent duplicate messages from getting dropped from the message archive
locations.

 

Details:

 

First, I am referencing the three archive locations, here:

 

Primary (Long-term):
http://www.mail-archive.com/nfc-l@cornell.edu/maillist.html

Secondary (Long-term): http://www.surfbirds.com/birdingmail/Group/NFC-L

Tertiary (Short-term): http://birdingonthe.net/mailinglists/NFCL.html

 

It had come to my attention that some messages are variably not successfully
being archived into the three archives available for NFC-L.

 

For the past several weeks, I have been working with these various Archive
Managers and Owners and the Cornell ListManager to identify what is causing
messages to seemingly drop from the archive - never even appearing.

 

A variety of contributing factors were identified, some of which we, as
Managers/Owners don't have any control over.


One of the factors that can prevent messages from being properly archived
has to do with an email's unique Message ID. Each time a user creates and
sends an email message, that email message will be assigned a unique Message
ID "number", regardless of how many email addresses the message is addressed
to in either the To: or Cc: field. This means that if a user sends a message
to List A and decides to Cc: the same message to List B, the message
arriving at List A and List B will have the same unique Message ID, even
though the recipient Lists are different.

 

Where this becomes a problem is in the "smart" way that many new email
servers are handling messages that appear to be "identical" through the
comparison between Message ID's. If there is a subscriber who is only
subscribed to List A, they will not see this as a problem. If there is a
subscriber to both Lists A and B, they may likely see a problem; their email
server will allow the first message arriving into their server to be
processed as normal, but recognize the second message (arriving split
seconds later) as a duplicate and trash that second "duplicate" message,
before it even goes out for delivery to their email address. The result is
that a subscriber to Lists A and B may only get that cross-posted message
from List A and not from List B, or vice versa, depending upon arrival time.

 

Now, apply this to the Archives. The Archives are treated in the same way
that any subscriber is treated. The Archives are created from a subscribed
email address. If said Archive "subscriber" is subscribed to Lists A and B,
that Archive will only "see" a single duplicated or cross-posted message -
the one which is received first by the Archive's mail server. As a result,
any cross-posted message might show up in email Archive for List A and not
in email Archive for List B, C, D, E, etc., even though the message was
originally addressed to multiple other email Lists.

 

A relatively simple work-around for this, although perhaps a bit clunky, is
to generate a unique message for each List. It probably takes an extra 20
seconds per List address (cut-and-pasting the entire message into a new
email for each List). I realize this may not be feasible or convenient for
many to do in this way. The benefit in doing this, is to produce a unique
Message ID for each message sent to each email List, allowing each
respective multi-List-subscribed email address to receive each
"cross-posted" message; thus, allowing each message to appear in each
respective email Archive for the greater good of future references to the
Archives.

 

In summary, please try not to cross-post the same message to multiple eLists
- in other words, do not add multiple email Lists in the To: or Cc: fields
of a new message.

 

Instead, please generate a separate email message for each email List you
wish to post to. This will help prevent messages with duplicate Message ID's
from getting deleted by "smart" email-handling programs and, thus, help
prevent duplicate messages from getting dropped from the message archive
locations.

 

Thanks very much to those who took the time to read this long-winded
explanation!

 

If you have any questions or comments, please do not hesitate to contact me
off List.

 

Thanks again and good birding!

 

Sincerely,
Chris T-H

[nfc-l] Audio File Converter

[Chris Tessaglia-Hymes]

This message is for those of us who may still have some of those old AIF
format night flight sound recordings kicking around, but have been looking
for an easy way to convert them to WAV format (or other output file types).

 

So, I thought I'd share with everyone an excellent audio converter that I
just found and successfully tested. It's called Fubar2000.

 

http://www.foobar2000.org/

 

It's freeware, no gimmicks (except for the ads on the page.don't click on
those - including the fake "Download" button - just click on the actual
version releases under "Latest news").

 

It was pretty easy to figure out how to use. I needed to convert a huge
batch (1,282) of audio files from AIF format to WAV format. I added the
batch of files (or the directory) to be converted, right-clicked on the
highlighted files, and chose "convert" from the menu. Then I changed the
output directory, crossed my fingers, and clicked the "Convert" button.
Within 2-3 minutes, I had all 1,282 files converted and conveniently placed
in the output directory that I had created.and they worked!

 

The conversion does not eliminate the original files; it creates a new copy
of the files in the format of your choice (default is WAV).

 

Hope this is helpful - it was for me!

 

Good night listening!

 

Sincerely,
Chris T-H

[nfc-l] Dickcissels - Etna, NY

[Chris Tessaglia-Hymes]

This morning, I recorded my fourth DICKCISSEL over Etna, NY in the past
seven nights. This particular flight call was the best yet.

 

I have uploaded an audio clip of the Dickcissel from this morning (at 2:47
AM), as well as a spectrogram frame-grab, showing the characteristics of
this flight call. These can be accessed by going to these links:

 

Audio:

http://www.NortheastBirding.com/111007.024749_DICKCISSEL_Etna_NY.wav

 

Image:

http://www.NortheastBirding.com/111007.024749_DICKCISSEL_Etna_NY.jpg

 

Note, the audio file is five seconds in duration, with the flight call
occurring at approximately 2 ½ seconds into the clip.

 

This particular call consisted of five distinct note peaks and with a single
fainter introductory and closing note, for a total of seven identifiable
peaks.

 

I simply didn’t expect to detect anything on the recording from last night,
given how quiet it was, let alone get something as good as a (another!)
Dickcissel flight note.

 

One question I have is about the relative abundance of this species: Is this
a particularly good year for them in the Northeast? Did they have a fabulous
breeding season in the Midwest? Did a particular weather pattern over the
past week or so cause them to migrate up into Canada or up to the Great
Lakes, East, then down South from there? Or, are they a more typical night
migrant through Upstate/Central New York than we give them credit for?

 

Thanks and good night listening!


Sincerely,
Chris T-H

I concur that the single call note is typical in nocturnal migration. I have 
probably heard hundreds of single call notes from nocturnal migrants in Cape 
May, but the only time I recall hearing multiple-note vocalizations as in 
Bill's cut is when a bird was flushed from a marsh.

Hi all,
I've certainly heard American Bittern produce isolated notes more
often than not when I've heard them migrating at night, both in the
field and in the lab from recordings; I'd hazard a guess to say that
the single note call is more likely to be encountered . . . but this
is really pure speculation, when it comes down to it, because I've not
heard a tremendous number of bitterns in flight at night!

Is it most typical for American Bitterns to produce these paired calls during

RE: [nfc-l] An observation and ID help

[Chris Tessaglia-Hymes]

Hi Dan,

 

I'll take a stab at these images:

 

 

The first three images ("Unknown [clip2]", "Unknown [clip4, A]", "Unknown
[clip4, B]") all look like faint Savannah Sparrow night flight calls.

 

The fourth image ("SAVS?"), looks like a perfect Savannah Sparrow night
flight call.

 

The fifth image ("PIWA? SAVS?") is likely another Savannah Sparrow night
flight call (versus Pine Warbler), in part, because of the faint harmonic
visible.

 

The sixth image ("Wood Thrush?") does look pretty good for Wood Thrush.

 

Seventh image ("upsweep") seems most likely to be from a Northern
Waterthrush.

 

Image number eight, ("Wood Thrush NFC?") looks like it could be a faint Wood
Thrush flight call.

 

Image number nine ("BLBW?") is probably a Blackpoll Warbler.

 

Lastly, image number ten ("Unknown NFC") looks good for a shortened or faint
White-throated Sparrow night flight call.

 

 

 

Anyone have differing suggestions for these clips?

 

Thanks and good night listening!


Sincerely,
Chris T-H

So far this 'fall' migration I have heard almost no calls during

night-time listening (say about 10PM through 1AM) from my hillside in

Passaic County, NJ.  I was puzzled why the birds appearing on radar

and apparently being heard by other posters on NFC were not calling in

my area.  Today I decided to get up pre-dawn and see if I could hear

birds in the morning.  Maybe at 'night' they were too high up because

of local topography and I could not hear them but as they descended in

the morning I would?

 

My hunch worked out and I heard many calls this morning, mostly SWTH,

when got outside despite hearing nothing between 10 and 11PM last

night. Anyone have any idea why this might be? I have no idea if my

topography guess holds any weight or if some other factor might be

playing a role.

 

Additionally, I have posted four new spectrograms from this morning's

recordings on my Flickr page.  These might be simple IDs, but I am

still learning the ropes and any comments are appreciated. The new

images all have 9-26-11 in the description.

[nfc-l] Upland Sandpiper: Etna, NY

[Chris Tessaglia-Hymes]

Good morning!

 

Just wanted to drop a note to say that I heard my first real-time night
flight call of the fall while star-gazing this past Saturday night
(7/30/2011), around 11:00pm.

 

I've not been able to do much night listening or recording of late, so it
was quite a pleasant surprise that it was a not-too-common species. The call
heard was the bubbly four-noted flight call of the Upland Sandpiper
"Bweep-bweep-bweep-bweep!"

 

It was definitely pretty cool.

 

Good night flight call listening this fall!

 

Sincerely,
Chris T-H

ADMIN: RE: [nfc-l] odd NEXRAD pattern

[Chris Tessaglia-Hymes]

David, and others,

 

Below is an excerpt from the NFC-L List Information and Rules page
(http://www.northeastbirding.com/NFC_RULES). RADAR discussions, as they
pertain to bird migration, are perfectly acceptable (as are limited-sized
attachments - I think under 900 kb is safest; Lyris limits at about 950 kb,
including message headers).

 

Please do feel free to continue!

 

NFC-L is an email list (the List) focused on the discussion of the night
flight calls of migratory birds.

 

The primary purpose of the List is to provide an effective electronic forum
for experienced birders to discuss the identification of night flight calls
of migratory birds, exchange ideas about recording equipment design and
setup, disseminate information about active or predicted night flights in
your area, and to better understand weather and RADAR data as they relate to
patterns of nocturnal bird migration.

 

Initially, attachments containing limited-sized sound files, photographs,
frame-grabs, or other documents to help further the discussion and shared
knowledge of nocturnal bird migration will be acceptable and are encouraged.
Be advised that attachments can also serve as a mode for spreading
infectious computer viruses. Use caution when opening any attachment.

 

Thanks!

 

Sincerely,
Chris T-H

Jeff Buler at U Del is doing some great radar ornithology work and passed
this link onto me. It's great to see the atmospheric folks getting into the
biological side of things; what started out as just "noise" has turned into
something much more interesting, I think. Anyway, the SOAR website is great
for screening nights for migration and looking at things at the national
scale (although you can zoom in locally too!). Give it a whirl- and with
that, I will refrain from further hijacking of the NFC list with radar posts

David and others,
You were asking about where to get archived soundings/wind data.  There is a
lovely archive at the University of Wyoming's website here: 

http://weather.uwyo.edu/upperair/sounding.html

and equivalent archived upper-air maps here:

http://weather.uwyo.edu/upperair/uamap.html

and real-time profiler data here (only found over the Great Plains):

http://weather.uwyo.edu/upperair/profiler/

>From there you can select an image type (stuve or skew-t is likely
preferred, but hodographs are available as well if that is what you know how
to read).  Then select the date and time (remember it is all in UTC) and
then a location.  There are soundings here for all over the globe, so this
isn't a bad site to have on hand for investigating other sites outside the
US.  You don't need to know the number of the sounding station, you can just
click on it on the map.  If you select stuve or skew-t the winds will be up
the right side and those correspond to the heights and pressures listed on
the left side of the chart.

Here are the soundings from Omaha, NE and North Platte, NE for the closest
times to Bill's original observations.  Note the significant difference in
winds in the low levels.  Omaha shows a strong north-northwest wind, while
North Platte shows a highly variable wind direction and light winds at low
levels.  This suggests exactly what David and others have theorized about.  

Omaha: http://tinyurl.com/3nbtoyv
North Platte: http://tinyurl.com/3gwtu48

Another way to look at this, although not observations is to look at the
streamlines from recent model output.  I plot streamlines on my website
here:

http://homes.comet.ucar.edu/~guarente/birdweather/stream.htm
<http://homes.comet.ucar.edu/%7Eguarente/birdweather/stream.htm> 

I unfortunately have not set up an archive yet for my site due to space
limitations, but I might be able to rerun that date to show the effects seen
in the soundings and on radar if anyone wants to see it.  This kind of
pattern often happens with the passage of weak fronts.  The winds start to
either turn around quickly due to local effects or the winds are so weak
behind the front that migration can easily occur even in the face of a
northwest wind albeit light.

RE: [nfc-l] reflections on a monumental nocturnal migration

[Chris Tessaglia-Hymes]

On the night of the 14th annual Montezuma Muckrace (10th-11th), our team
(The Gallinagos - consisting of Jeff Gerbracht, Kevin McGowan, Gerard
Phillips, and me) recorded the bulk of the night migration from a location
just Southwest of the Village of Savannah, New York, from about 10:45pm
until a little after sunrise. The recording was made using a Zoom H4n
Recorder and a single Sennheiser MKH 20 omnidirectional microphone. Gerard
and I skimmed the audio files already, but I intend to do a much more
in-depth tally when I have more time. We can add these data to the map for
comparison purposes.what an amazing night migration, indeed! When I have
final numbers, I'll post them to this List.

 

Question: should we be reporting these kinds of numbers into eBird?

 

Thanks and good birding!

Chris T-H

Bill & David -

 

Andrew Farnsworth and I have 6 ARUs deployed within the greater NY metro
area, so we too have recordings for that night. Can't wait to see what they
hold (though everything may not be extracted and classified for few months).
I was listening for about an hour on the night of the 10th and heard many
more flight calls than I've ever heard from my house, so the flight should
be interesting to quantify (and interesting to compare to the Cape May
mics).

 

Good listening, watching, and predicting, everyone!

ps. we have data from several mics around Cape May for that night- so we

Nfcers,

I begin by stating simply that if anyone ever substantiates a future
nocturnal vertebrate migration over interior northeastern US (in the first
two weeks of September) bigger than what occurred the night of Sep 10-11,
2010.I will buy fine ale for the whole nfc listserv membership at a pub
of consensual choice somewhere on the planet. So, for those who have an ear
to hear and an eye to see in this manner, take note of future fall
migrations over northeastern US in case of cashing in on my offer. I wager,
given the rarity of such large nocturnal migrations in the past 20 years,
and the crushing inertia of human civilisation, that a flight the density
and breadth of Sep 10-11 2010 will not happen again in our lives across
interior northeastern USA.  If so, I will be singing "kumbaya" in reverance.

As I recall, it was about a week in advance that I began preparations to
surf the then subtley-evident behemoth wave. Allocation of spousal attention
was reduced; the kids welfare rationalized circularly by my pending
documentary actions. We walk a thin line of sanity in this nocturnal
migration preoccupation, especially so during wartime and amidst other human
tragedies on our nerve within a keystroke. But we prevail in the bigger
picture, imprinting earth with our natural history activities, respectfully
& nonetheless.

The pulse of migration over central New York State on the night of Sep 10-11
rocked the relative historic framework. My initial calculations were off
(http://www.birdingonthe.net/mailinglists/NFCL.html#1283970775), but you
only lose in such events when you miss them. The flight happened two nights
later than I thought, and Catharus fuscescens y Wilsonia pusilla flight
calling turned out to be normal for the time of year, instead of the higher
numbers and proportions I had guessed. But the number of migrants aloft
burst forth with full remnant ebullience. That density was nature-born and
the species composition a delightfully telling ancient echo. The flight is
now just a memory for a few of us, but indicative records remain:

Seeing that map also got me wondering, where IS everyone on this list? (I

I've created a Google Map where you can enter your location, if you wish. I
figured this would be a good way for all of us to know what areas are
covered, need coverage, and/or a way for us to meet up and coordinate some
night listening. This is a public map, so I wouldn't put too much info. I
put my name in the town where I live, but left out any specific address, or
any equipment notes. It might be interesting to put whether you have a fixed
listening station and if it will be running throughout the season, but I
leave that up to you to decide. We can also make it private, and invite the
entire group, in which case we might feel more comfortable sharing more
specifics. Again, I leave this up to the group to decide.

This may sound rather sad, but I can't seem to figure out how to add my
location. I can add my address, but I can't seem to figure out how to edit
the name of the address.

where he can go to go crazy in peace. Every Boy Scout deserves a forest to
get lost, miserable, and starving in. Even the maddest murderer of the

If only for the sport of it. For the terror, freedom, and delirium. Because
we need brutality and raw adventure, because men and women first learned to

I've created a Google Map where you can enter your location, if you wish. I
figured this would be a good way for all of us to know what areas are
covered, need coverage, and/or a way for us to meet up and coordinate some
night listening. This is a public map, so I wouldn't put too much info. I
put my name in the town where I live, but left out any specific address, or
any equipment notes. It might be interesting to put whether you have a fixed
listening station and if it will be running throughout the season, but I
leave that up to you to decide. We can also make it private, and invite the
entire group, in which case we might feel more comfortable sharing more
specifics. Again, I leave this up to the group to decide.

Here's the map link:

Hi all,

Great post - I, too, am eager to see what happens with the development of
this system.  Following David N and David LP thoughts, with such strong
southerly flow over the Gulf of Mexico later this week, I'd expect a nice
pulse of early spring migrants into the Gulf states and beyond; with winds
at 925 mb at the speeds currently forecast, it appears that trans-Gulf
flights would head far inland assuming no adverse conditions after crossing
the Gulf coast upon arrival in the US.  So, too, for migrants the central
and eastern US, I'd expect a pulse of late winterers, facultative migrants,
and early spring arrivals to take flight (I agree with David LP in comments
farther below in what he suggests about obligate nocturnal migrants that are
farther afield in points south - however, I'd think a good chance for early
Neotrop. stragglers of the longer distance type in Texas given the strength
and magnitude of the flow predicted - attention to TXBIRDS and FLBIRDS
should indicate that if we see/hear it!).  

 

As Dave N. suggested, a little later this week would be a great time to
deploy your microphones. . .central/eastern Plains states Monday/Tuesday and

Re: [nfc-l] YT or OC warbler?

[Chris Tessaglia-Hymes]

This call appears to be too short in duration (~22ms) for nearly all of 
the "short upsweep" warblers (sans Black-throated Blue) and seems to be 
lacking the "double-banded" feature of several of these types. This 
flight call also appears to start potentially as low as around 5.1 kHz, 
which is below the starting frequency of several of these warblers. 
Granted, there's bound to be all kinds of possible variation. In looking 
at the structure of this call note, it appears very similar to that of a 
Northern Cardinal. Is it possible that this was a slightly distant chip 
note from an evening-settling Northern Cardinal, or perhaps one 
disturbed from its roost? Maybe I'm way off here, but is this a possibility?


Sincerely,
Chris T-H

Re: [nfc-l] When does night end?

[Chris Tessaglia-Hymes]

When I've listened to night migrants over Etna, NY, or for the purpose 
of counting calls from a entire night of recording, I generally consider 
night to end around civil twilight. More specifically, my audio cue is 
when the apparent night sounds cease and the Blue Jays and American 
Crows begin calling. There's usually a gap of a minute or so of 
separation between these groups in the morning (night and day). As for 
the start of a night migration...I'm usually late in setting up, so 
don't typically hear when the first birds start calling, relative to 
civil twilight.


Sincerely,
Chris T-H

Hi, 
  in discussing night flight calls I am a bit confused about the concept of "night". Astronomically, I have no problem with the true night, and the various twilights. If the limit of "night" is taken at sunset/sunrise, then various day birds fall into the category of night flight calling birds even if they are not proper night migrants. Tits (chikadees), crows and finches start to vocalise before well sunrise, during the civil twilight, and gererally they do not crowd the sky in the deep hours of the night.

There appears also to be an assymetry between dusk and dawn. During the same 
light conditions the duirnal birds at dusk tend to be much quiter than at dawn, 
so this is not that miuch of a problem in the evening.
My question is when do you guys consider the night over?

Hi all,

I haven't had much time for day-time birding these past few days, but 
I've been out every night listening to the sky from my yard. I had 
large flights of migrants on Friday and Saturday night (around 
midnight both nights), but last night with SW winds I only heard a 
few warblers.

On Friday and Saturday night I heard large numbers of VEERYs and 
ROSE-BREASTED GROSBEAKS (over 100 calls in 30 minutes), and I'm 
pretty sure I heard my first SWAINSON'S THRUSHES on Saturday -- I 
find early September the trickiest time to i.d. flight calls, as 
grosbeaks (and probably some tanagers and others mixed in) can 
overlap the thrushes, at least to me.

Another highlight, on Saturday night, I had a LEAST BITTERN fly low 
over my house, calling at least 4 times very clearly - like a 
miniature night-heron "wark"  It was so low, I thought I might see 
the silhouette against the fullish moon, but no luck.

Re: [nfc-l] call ID - Crow?

[Chris Tessaglia-Hymes]

Hi Pete,

I believe that is a call from an American Crow. I don't remember what 
the name is to describe this type of call. But, it's that more clear and 
somewhat higher frequency series of "guttural" notes that I've heard 
being produced by crows in the past. I think Kevin McGowan might be the 
best person to answer this question. Anyone else know the call type or 
name/purpose?

Sincerely,
Chris T-H

Re: [nfc-l] Engineers - chime in? Adaptive Noise Cancellation

[Chris Tessaglia-Hymes]

Okay, last post for the night

The more I read about this, the more and more it sounds really cool.

So, you software and hardware engineer people out there - what do you 
think? Can it work to better clean up night flight call data collection? 
Heck, this could get you closer to that 90-95% positive detection figure 
we'd all like to see.

Re: [nfc-l] Adaptive Noise Cancellation

[Chris Tessaglia-Hymes]

I think the idea with adaptive noise cancellation is this:

you have a dual microphone system. One channel is the primary channel 
(collecting the target sounds). The second channel is the "noise 
collection" channel. Through some mathematical algorithms, you subtract 
the noise collected in the "noise" channel from the primary channel 
(e.g., a different microphone aimed at collecting the cricket sounds or 
the katydid sounds, perhaps using a slightly lower gain setting, so as 
/not /to pick up distant flight calls being collected in the primary 
channel). The resulting signal in the primary channel should have 
reduced cricket and katydid sounds. Well, that's the theory, I guess.

Here's an older paper abstract from 1975. Current technology can 
probably do this adaptive noise filtering in very real-time.

problematic for detectors...

Hi All,

I've been recording from my home in south Louisiana with set-ups like
Chris and David over the last few years.  I've been using the oldbird
software (tseep, etc), but only get about 20% of the flight calls that
I would otherwise detect by ear (and visually on spectrographs).  Not
only is the detection software missing many calls, it's also
underestimating the richness that I could get.  In one of my best fall
nights I more than doubled the species richness by listening through
the entire night compared to running it through the software.  What's
also frustrating is that I get a TON of trash clips - many more than
birds clips.  I've tried to filter out background noise (which is
mostly insects and air conditioning units) before running the file
through the auto-detect software, but it doesn't change the results
much.  I haven't toyed with the other programs that have been
mentioned in this threat, but as I understand it, they also don't get
near 100% - or am I wrong - it sounds like this technology improving
quickly.  This list serve is giving me new inspiration to hook up the
mic this fall and to play around with more settings and programs.  I'm
eager to see the upcoming manuscript and to hear everyone's thoughts
on this subject!

Happy listening,

[nfc-l] NFC Detectors and Equipment?

[Chris Tessaglia-Hymes]

Hi everyone,

In the past, I have not used any detectors when going through my night 
recordings at home (Etna, NY). I have collected my sound data from the 
roof-top microphone (Evans-style, with a Knowles microphone element) 
piped into my home computer running Raven Pro, recording a continuous 
file sequence from start to finish with each file duration equal to 1 
minute. The following day, I would browse through the sound file 
sequence by hand, again using Raven Pro, looking for sounds of interest. 
Once a sound of interest was worth saving, as an example of a good 
flight note for species x, or an interesting unidentified species flight 
call, I would cut-and-paste that sound file into a new window and save 
it with a time-stamped label, uniquely pairing it to the file/time it 
was copied from.


Now, this is all fine when you are a single person, operating your own 
home station, only recording on those nights which appear to have good 
night flights. But, when you begin operating to capture every night from 
multiple stations, or you want to really quantify most or all of the 
calls that night, the question of data storage and data processing 
becomes the big issues.


How do some of you out there collect your sound data?

What tools do you use for browsing sounds?

Do you only use detectors?

Here's a question for probably three people on this list:

What is the difference between the current Raven Pro detector that Mike 
Powers provided settings for and the old BirdCast transient detector? Is 
there a difference?


Getting back to an earlier posting from Tom Fowler (prior to the bloom 
in membership...140+ now!), what kind of equipment do you each use for 
recording or listening to your sounds?


I mentioned that I use a variation on the Bill Evans-style flowerpot 
microphone. I know that Andrew Farnsworth and Mike Powers use a 
microphone, pre-amp, and housing designed by engineers at Bioacoustics 
at the Cornell Lab of Ornithology, storing their night sounds on flash 
memory inside a SoundCache for analysis later, but what do others use?


What are your personal home recording setups like?

What obstacles or limitations have you encountered with your equipment 
setups or recordings?


I realize these are a lot of questions, but I wanted to pose these to 
the list in order to help initiate discussion along these lines.


Information about Bill Evans's flowerpot design can be found here: 
http://www.oldbird.org/ (click on Microphone Design in the left panel)


Information about the Raven software can be found here:

Chris,
Cool - just within the past week here in Churchill, Manitoba, the 
warblers have started flight calling again with considerable frequency 
(especially Yellow, Blackpoll, Yellow-rumped, and Orange-crowned), even 
though it seems that most of the birds calling are locals still on 
territories.  During spring migration (which this year extended until 
the third week of June here for some warblers), Yellow/ Blackpoll 
Warbler flight calls are one of the signature sounds of Churchill, but 
they go very quiet during nesting (as in down south).
Cheers,
Tom

[nfc-l] ADMIN: NFC-L Subscribers

[Chris Tessaglia-Hymes]

Good morning,

This message is to let everyone know who's who on NFC-L. There have been 
a couple of new subscribers recently.

NFC-L is an email list focused on the discussion of the night flight 
calls of migratory birds.

The primary purpose of the List is to provide an effective electronic 
forum for experienced birders to discuss the identification of night 
flight calls of migratory birds, exchange ideas about recording 
equipment design and setup, disseminate information about active or 
predicted night flights in your area, and to better understand weather 
and RADAR data as they relate to patterns of nocturnal bird migration.

Initially, attachments containing limited-sized sound files, 
photographs, frame-grabs, or other documents to help further the 
discussion and shared knowledge of nocturnal bird migration will be 
acceptable and are encouraged.

I also just looked at the current surface analysis weather map and the

birds...or not...

I should add that among the numerous acts of misinformation in the article 
that John cited is the estimate that only "7000 birds" are killed a year by 
wind turbines in the US. Anyone can do a little research on the web to 
debunk this.

We are approaching 30,000 wind turbines in the US now and we have about 500 
in New York. A bird and bat fatality study at the ~200-turbine Maple Ridge 
wind project on the Tug Hill Plateau in northern NY estimated that project 
alone killed ~2000 birds in only a 5 month period from July through November 
2006 [I am happy to send anyone the study].

The current number of birds killed at US wind turbines per year is difficult 
to estimate because Texas, with 10,000+ turbines, has not yet produced a 
credible fatality study. But estimates I've seen that are widely accepted 
put the figure at more than an order of magnitude higher than 7000 and 
growing rapidly. Whoever wrote the article John cited did not do there 
research.

This radar scam appears to be in full service as a PR campaign well before 
any critical peer-review of its effectiveness.

Bird migration in the coastal bend of Texas is going on 24/7 for 9 months a 
year. It is true that a radar system can detect flying animals and wind 
turbines might therefore be shutdown on nights with some predetermined 
density of migration. But the combination of the protracted breadth of 
migration in the Texas coastal bend and the massive quantity of birds 
traversing this region (possibly the densest annual bird migration rate in 
all of the Americas) is not likely to make such radar measures effective for 
anything other than PR.

It simply doesn't make sense economically or environmentally to build large 
commercial wind farms in locations where dense migrations would necessitate 
them to be shut off for significant periods. This was a hideous location for 
a wind project from the bird impact standpoint, a terrible precedent for the 
wind industry, and a testament to the ineffiveness of our Government (Fish & 
Wildlife Service) and our nature and conservation orgs (e.g. Audubon, Sierra 
Club, NWF etc) for implementing bird-safe siting of industrial wind projects 
in this region of the US (texas).

These are our birds that are and will be killed by this project for decades 
to come -- perhaps a lawsuit against the state of texas is in order.

We may finally have a solution to wind farm bird collisions. The radar based 
system
being employed in Texas appears to be effective. It would be a logical 
requirement
for all commercial wind installations. See this link:

Hi all,
This is as much a test as it is a message. . .

Just a FYI - tonight and tomorrow night will presumably provide
additional opportunities to sample this "cool (no irony intended)"
mesoscale weather pattern.  Large numbers of birds have arrived across
the NE and adjacent regions, and some of the past few nights have had
great flights.  If you can record, get those mics out. . .

Best,
AF

[nfc-l] ADMIN: Welcome to NFC-L!

[Chris Tessaglia-Hymes]

This message is for those of you whose email addresses were recently 
added to NFC-L, at the recommendation of Andrew Farnsworth:

Welcome to NFC-L!

NFC-L is an email list (the List) focused on the discussion of the
night flight calls of migratory birds.

The primary purpose of the List is to provide an effective
electronic forum for experienced birders to discuss the
identification of night flight calls of migratory birds, exchange
ideas about recording equipment design and setup, disseminate
information about active or predicted night flights in your area,
and to better understand weather and RADAR data as they relate to
patterns of nocturnal bird migration.

Initially, attachments containing limited-sized sound files,
photographs, frame-grabs, or other documents to help further the
discussion and shared knowledge of nocturnal bird migration will be
acceptable and are encouraged. Be advised that attachments can also
serve as a mode for spreading infectious computer viruses. Use
caution when opening any attachment.

Please take a moment to review the Welcome and Configuration
<http://www.northeastbirding.com/NFC_WELCOME> and the Information
and Rules <http://www.northeastbirding.com/NFC_RULES> pages for the
List.

Please also realize that the List is in its infancy. The purpose of
the List may morph over time, as well as the guidelines and rules
for use. The List will always have the primary focus of flight calls
(both nocturnal and diurnal) of migratory birds.

If you have any questions, please do not hesitate to ask me.

Thanks and good night-listening!

Currently, the following email addresses have been added to the list, 
just so you know who will be reading or contributing posts:

If you think there are additional persons potentially interested in or 
who should be included on the list, please email me, or forward the 
NFC_WELCOME link below. The list is restricted for the time-being, in 
that each membership requires manual approval by me. Posting is not 
moderated.

Any questions, please do not hesitate to email me, off-list.

Thanks!

Sincerely,
Chris T-H
