[cobirds] Greater Yellowlegs, Cottonwood Marsh, Boulder

2015-02-08 Thread Peter Burke
COBirders,
Early migrants? There were two Greater Yellowlegs on the marsh Saturday,
actively feeding and making their distinctive, high-pitched flight call.
It's not often this bird shares scope-views with Common Goldeneye!

There are decent numbers of both diving and dabbling ducks out there. Also
a cooperative Northern Shrike on the west side of Duck pond.

Good birding,

[cobirds] Larimer - Fort Collins - Chihuahuan Ravens???

2015-02-08 Thread John Shenot
I am realizing this morning with almost a sick feeling in my stomach that I 
may have seen ~12 Chihuahuan Ravens last weekend (January 31), but didn't 
consider that possibility at the time and didn't make the effort to be 
sure. So take all of this with a grain of salt. I am not a beginning birder 
but I always say (without modesty) that my identification skills are not 
very good.

I was walking my dog at the flat part of Reservoir Ridge Natural Area in 
Fort Collins. The habitat is grassy/brushy and just a quarter mile or so 
from the first of the foothills. I had binoculars but also had a dog 
tugging at the leash. On the far side of the small pond south of the trail 
I saw large black birds on the ground. More flew in. Then they took off to 
the north, flying over my head. Looking through the bins while holding onto 
my dog, I was frustrated with my ID skills because I couldn't tell if they 
were American Crows or Common Ravens, two species I thought I could 
distinguish most if not all of the time at this distance. The dog kept 
tugging, and I moved on, feeling incompetent. 

It was only yesterday when I first thought (briefly) about the possibility 
of a third option. This morning I pulled out my Sibley guide and listened 
to some recordings, and I find myself leaning toward an ID of Chihuahuan 
Raven. The sense I had at the time, and the reason I struggled with the ID, 
was that the birds didn't have textbook wedge-shaped tails, making me think 
crow. But they seemed large for crows, the head and bill seemed to stretch 
out too far in front of the wings, and they soared a little bit (not 
much) in flight, making me think raven. I was also thinking at the time 
that their calls didn't sound quite normal for crow or raven. I listened 
to a recording of CHRA this morning, and it seems like that is what I heard 
- but I don't trust my memory of a call I heard more than a week ago.

Bottom line: I don't expect confirmation and I don't think anyone could 
chase an observation from a week ago. But to the birders of Larimer County, 
especially anyone birding around the foothills, I wanted to post this 
reminder to keep in mind the possibility of CHRA so you don't find yourself 
in my shoes, a week after the fact, wondering...

RE: [cobirds] Lake Minnequa, Pueblo Co. 2/6 swan scoter

Swan and scoter still present around noon today.  Both were near the southwest 
corner.

Subject: [cobirds] Lake Minnequa, Pueblo Co. 2/6 swan  scoter

Leon Bright and I were over at Lake Minnequa in the central part of Pueblo 
around 11am, and saw the adult Tundra Swan and a female/immature White-winged 
Scoter.  
The best place to park when it is sunny out, in the morning, is the overflow 
Hospital parking lot, south of St. Mary Corwin Hospital, along Lake Ave.  This 
is the east side of the lake, looking west.  The light from here in the 
afternoon looking west, is probably not the best.  The scoter was straight out 
from this parking lot and the swan was toward the south east corner, with some 
Canada Geese.  I think this is probably the same White-winged Scoter that has 
been at Pueblo Reservoir since late December. Good birding,

[cobirds] Re: Greater Yellowlegs, Cottonwood Marsh, Boulder

2015-02-08 Thread Tom Wilberding


Early migrants or Colorado over-wintering? Always great to see a shorebird 
in winter. Bob  Bob, *Colorado Birds* © 1992, mention GRYE as “occasional 
in winter.” Killdeer rated “rare in winter.” The only other shorebird with 
a winter mention is Wilson’s Snipe, “local in winter.”

But for the past two January's there have been quite a few eBird sightings 
of GRYE in January, particularly Boyd Ponds in Fort Morgan and Barr Lake. 
Open water is probably key. Prior to 2013 the only January GRYE sighting 
was at Wheatridge Greenbelt in 1988, 27 years ago. Click to see the eBird 
January map here 
http://ebird.org/ebird/map/greyel?neg=trueenv.minX=-107.36977274481012env.minY=39.400237272041736env.maxX=-102.09633524481012env.maxY=41.230426848658965zh=truegp=falseev=Zmr=onbmo=1emo=1yr=all.
 
What to conclude? A couple of unusually warm winters, or evidence of 
serious climate change, for better or worse? Gulp.

Anyway, gotta love this shorebird with anti-freeze.

[cobirds] Mew Gull, South Platte Reservoir, Jefferson County side

2015-02-08 Thread David Suddjian
In the growing light before sunrise this morning (2/8) I saw an adult Mew
Gull among a nice gull flock on what was left of the ice at South Platte
Reservoir, in the Jefferson Co portion. Two Lesser Black-backed Gulls were
also present. The Mew had lost most of its wintertime streaks and smudges.
Pretty much all the gulls flew off to the south before sunrise.

When I drove by in the early afternoon nearly all the ice had melted.
