[cobirds] Early shorebirds, Lake Estes, Larimar Co., Earth Day

[Jim Nelson]

Continuing to enjoy our April visit to Colorado in Estes Park, I took a late 
afternoon walk at Lake Estes.  I was surprised to find three species of 
shorebird -- a single Marbled Godwit (never reported for the Estes Park area in 
eBird), 4 Willet (only one other April report in eBird for this species in the 
Estes Park area -- April 24, 3013), and two Spotted Sandpipers (6 days earlier 
than the earliest prior reports in eBird for the Estes Park area).


Also had two Barn Swallows, the first in eBird for Estes Park this year.

Observation start time: 09:00:00 
Observation end   time: 13:00:00 
Total observation time: 4 hours

Official Counter:Mitchell Blystone

Observers:

Visitors:
Very little!  The trail had a couple hikers and bikers but nothing like a
typical Saturday.  Only two different couples came up to the landing.


Weather:
The morning started cold and calm with a low ceiling. Throughout the day
the wind increased and the temperature rose.  Eventually the late afternoon
had an equal amount of sunshine to cloud cover. 

Raptor Observations:
An early fly over by 7 Turkey Vultures that were 30-40 feet above the deck
was a great way to start the day.  Additionally, 6 more TVs came to the
platform only to circle and then head to Matthew Winters Park and land
along the rocky cliffs.  
After those sightings the rest seemed to be shot out of a cannon!! The
morning was very active and all raptors seemed to be in a great hurry.
A couple local Red tails made appearances as well as some Kestrels and the
two interacted on a couple occasions. 

Non-raptor Observations:
Ravens and crows played along the eastern ridge for the majority of the
day.  A couple Scrub Jays, Towhees, Black-capped chickadees, Magpies,
White-throated Swifts, and a Rock Wren or two.  
The early morning had 20+ Elk along the Cabrini Shrine as well.


Predictions:
Not sure about predictions.  I did not observe any active high along the
western ridge but rather close to the Dino ridge's near east and west
sides.  Be on your toes!  If they are moving like today they are moving!!!

Report submitted by Bird Conservancy of the Rockies 
(jeff.bi...@birdconservancy.org)
Dinosaur Ridge - Bird Conservancy of the Rockies information may be found at:
http://www.birdconservancy.org/


Site Description:
Dinosaur Ridge is the only regularly staffed hawkwatch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Dinosaur
Ridge may be the best place in the country to see the rare dark morph of
the Broad-winged Hawk (a few are seen each spring). Hawkwatchers who linger
long enough may see resident Golden Eagles, Red-tailed Hawks and Prairie
Falcons, in addition to migrating Swainson's, Cooper's and Sharp-shinned
Hawks, American Kestrels and Turkey Vultures. Peregrine Falcons and
Ferruginous Hawks are uncommon; Northern Goshawk is rare but regular.
Non-raptor species include Rock Wren, and sometimes Bushtit, Western
Bluebird, Sandhill Crane, White-throated Swift, American White Pelican or
Dusky Grouse. Birders are always welcome. 
The hawkwatch is generally staffed by volunteers from Bird Conservancy of
the Rockies from about 9 AM to around 3 PM from March 1st to May 7th.

Directions to site:
>From exit 259 on I-70 towards Morrison, drive south under freeway and take
left into first parking lot, the Stegosaurus lot. Follow small signs from
the south side of lot to hawkwatch site. The hike starts heading east on an
old two-track and quickly turns south

[cobirds] Help with an injured goose?

['Deborah Carstensen' via Colorado Birds]

A couple of weeks I and a couple of other people he was able to catch an 
injured goose that had fishing line around his legs. I now suspicion there 
might be more line around its leg that I didn't get because he continues to 
mostly sit and it appears to be painful for him to put pressure on that leg.
  Is there anyone who would be willing to help me try to recapture the 
goose? He is semi tame and easy to get very close to, just not easy to actually 
get him in your arms.  
  If it looks like something that is not obvious on how to fix, I'm going 
to take him to a local emergency vet that does help me in the past with other 
geese.
   I live just south of Bowles off Platte Canyon Drive in Littleton.

[cobirds] Broomfield County 4-22-2017

[David Ely]

Greetings Cobirders,

This morning I birded some spots in Broomfield county.  Eric Zorawowicz
accompanied me at Plaster Reservoir.  We also ran into Tim Smart, Matt
Hofeditz, and the Broomfield Bird Club while we were here.   The best two
birds at Plaster were a male ring-necked pheasant (pretty darned rare in
Broomfield County) and a peregrine falcon which was eating a prey item on
the east side of the lake.  It flushed and flew off way to the west before
we could study and determine what it was eating.   Waterfowl diversity
remains high here and the numbers of redhead (23) and lesser scaup (55) are
locally impressive for the date.  Both Virginia rails and soras were
present and calling also.  Migrant passerine activity was slow with only a
single yellow-rumped warbler to be found.
After Plaster I went by Brunner Reservoir and was surprised to find 17
hooded mergansers here.  That is an impressive count for the date and
location.  Also here was a single canvasback and a few snowy egrets and a
spotted sandpiper.
On my way back to Boulder I stopped by Walden Ponds off 75th St.  I also
checked for the phoebes under the bridge at 75th and Boulder Creek.  Both
the eastern and black phoebe were about 25 yards upstream from the bridge,
mostly perched on the orange private property fencing on the north side of
the creek.
Overall, nothing nearly as exciting as a Vaux's swift, curlew sandpiper, or
yellow-throated warbler, but it was nice to be out anyway.

[cobirds] Pueblo birds on April 22nd

[Brandon]

Hi all,

What a great day of birding in Pueblo this morning.  It was overcast
in the morning.  Van Truan and I first saw a Lazuli Bunting and Brown
Thrasher in his yard in Pueblo.  Then we walked throughout Mineral
Palace Park, and heard a singing YELLOW-THROATED WARBLER in the south
west corner of the park.  The bird seemed to like the trees on the
west side of Court Street and north of 15th Street, across the street
from the Gas Station there.  There is a pine and a couple small trees,
that it seemed to be hanging out in.  Some other birders, David
Chartier, Glenn Walbek and Loch Kilpatrick all got to see it too.  Van
heard the bird yesterday morning, before he went to work, though
didn't see it.  Happy it was still around today!

Then Van and I drove over to Pueblo City Park and then walked, along
the Arkansas River.  We ended up walking west of the Pueblo Nature
Center, when I was looking over some Yellow-rumped Warblers, Van
spotted a SWIFT over head, with the swallows (which included all six
normal species).  I quickly thought, this is exact the same kinda of
thing, when the VAUX'S SWIFT was below Pueblo Reservoir dam, along the
Arkansas River on 28 April 2015 (and was accepted by the C.B.R.C. as
the 1st State Record).  A small swift flying around with swallows,
near the Arkansas River in April, caused me to quickly start
photographing the bird.  The light wasn't good, since it was overcast.
My photos mostly show the shape the bird.  The throat seemed lighter
than the rest of the bird.  We never really got looks at the rump
area, since it was flying higher up.  We'll see if my photos of the
shape of the bird, are diagnostic or not.  We feel like the bird was
shorter winged, with shorter tail, than Chimney Swifts.  One other
highlight, west of the Pueblo Nature Center, was an Ash-throated
Flycatcher.  We never found any other species of warblers, just a lot
of Yellow-rumpeds.

Finally, on the way home, I stopped at Pueblo Reservoir, and found a
nice variety of shorebirds.  Willet, Marbled Godwit, American Avocets,
Western, Semipalmated, Least, and Spotted Sandpipers.

Photos of the Yellow-throated Warbler and the Swift can be seen at
https://www.flickr.com/photos/brandonsbirdphotos

The swift photos show the shape of the bird, not really the color too well.

[cobirds] CSR, El Paso Co, Saturday

[Steven Brown]

Hey COBirders,

Today was my first day for banding at Clear Spring Ranch in 2017.  I had hoped 
the low ceiling, mist and SE breeze might deliver some migrants, and that 
happened, but not really until I was closing at about 1030.

The only real migrants to appear were 3 Lincoln’s Sparrows (banded), a small 
flock of Yellow-rumped Warblers (only one banded, a second-year male Myrtle), 
and 3 House Wrens, maybe migrants. Pretty quiet so far.

more soon,
Steve Brown

[cobirds] Birds at Boyd Lake S.P., Loveland

[marimammoser]

I went this noon to Boyd Lake State Park to find some of the birds that 
Andy Bankert had reported.
I did not travel the 1/4 mile north of the northern-most parking lot so I 
did not find the flock of peeps 
nor the Willets or Godwit or the Dowitchers. I did find 4 Long-billed 
Curlews and 3 Caspian Terns 
about 150 yards north of the northern-most parking area along with both 
species of Yellowlegs and 
about 25 American Avocets.

[cobirds] Excellent Boulder County Shorebirding today -- 15 species.

[Peter Burke]

COBirders,
I started the day at Boulder Reservoir (NW lot) where there were 12 Willet,
1 LB Dowitcher, 1 Marbled Godwit, 9 WF Ibis, 1 Semipalmated Plover, 1
Semipalmated Sandpiper and 1-2 each of Least and Baird's Sandpipers.
Wilson's Snipe could be heard displaying in the marshes. A large flock of
Franklin's Gulls plus a single winter plumaged Bonaparte's Gull were also
in the mix.

At Lagerman: 15 Marbled Godwits, a Spotted Sandpiper and a Willet, plus
just to the north in Swede's Pond, a LB Dowitcher, both Yellowlegs and a
Western Sandpiper.

At Cottonwood Marsh: Willet, American Avocet and a Solitary Sandpiper.
Would someone please let some water flow into the marsh?

Teller #5 is completely dry.

Sombrero Marsh is overflowing. A single Yellow-headed Blackbird was the
highlight there.

And finally, Baseline Res.: This looked like it might be the shorebird
hotspot this spring, but today all I could find were 2 Spotted Sandpipers.

[cobirds] Re: VAUX'S SWIFT Pueblo

[mvjohnski]

Very interesting Brandon. I just received a phonecall from a local birder 
whose relative is a young man from back east. He reports a "dark swift" 
that looked a bit smaller than Chimney Swift, with which he was familiar 
from back east. It was seen near Capulin in the San Luis valley just 
recently. We will be watching for it.

[cobirds] Plumbeous Vireo - Marjorie Perry NP - Arapahoe

[Jared Del Rosso]

Yesterday, I took my dog for a sunrise walk at Marjorie Perry Nature  
Preserve. We hoped to hear Virgini Rail (nope), Sora (nope), and Wilson's 
Snipe (seen, not heard, as one circled the marsh not winnowing). 




We covered most of the High Line Canal during our walk, encountering 
several Yellow-rumped Warblers and our FOS Wilson's Warbler (a few days 
later than last year's FOS at the preserve). We looked for, but did not 
find an Eastern Phoebe at the duck pond. It was about this time last year 
that one visited the preserve for a few days, but I think that one was 
brought in by a spring blizzard not by loyalty to Greenwood Village. 


But the highlights were two birds -- a Plumbeous Vireo (three weeks earlier 
than my FOS last year in w. Arapahoe Co.) and the continuing White-throated 
Sparrow. The vireo was among several other birds -- House Wrens, American 
Goldfinches, Black-capped Chickadees, and House Finches -- on the High 
Line. As for the White-throated Sparrow, I didn't see it, but instead heard 
it as it continues to work on its song. This time, it seemed  awful close 
to singing the entire thing. It was a treat to hear that song at the 
preserve. I spent my first summer birding in my wife's hometown in way 
northern Minnesota, where the White-throated Sparrow's unforgettable tune 
was one of the first unfamiliar songs that I learned. (Though only after 
taking the song for another person, whistling on the trail.)
