[cobirds] Say's Phoebe, Boulder

'Tis the season for... flycatchers?  After a Thanksgiving visit to South Dakota (where I added Great Kiskadee to my SD list, believe it or not), I returned home to find a very chilly Say's Phoebe foraging around the Kittredge Ponds at the south end of the CU campus in Boulder this morning.  Even eBird was surprised.

Good birding,

[cobirds] Colorado Breeding Bird Atlas: QUIZ

Hello, Birders.

One of the most important features of the forthcoming 2nd Colorado Breeding Bird Atlas is the change map--one for each and every species in the book. The change map provides an intuitive--and, in many cases, dramatic--feel for how a species' breeding range in Colorado changed between the two atlases. To see how it works, click on this link:

http://tinyurl.com/CFO-BBA-quiz-1

What species do you think this is?

We will be posting quizzes like this every couple of weeks until the Atlas is published. Learn more about the Atlas, and pre-order your copy here:

Lafayette, Boulder County

P.s. Hannah Floyd and I saw a prairie falcon this Saturday afternoon, Nov. 28, at Prince Lake No. 2, Boulder County, and then a prairie merlin over at Greenlee Preserve, Boulder County. Couldn't find a prairie warbler, though . . .

[cobirds] Barr Lake (Adams County) Birding on 11/28

I joined Niña Routh and her band of Black Friday Birders a day late this year for a half-day of birding at Barr Lake State Park.

 

We started in the NW corner by the BCOR (aka RMBO) headquarters where we had our most unusual birds of the day—5 Least Sandpipers trying to find some shore between the ice and the water.  Also in this area were a fairly large number of Mourning Doves for November (16) and a Say’s Phoebe.  Swinging around to the BLSP Visitor Center we worked through the 4 species of white and white-cheeked geese present as well as good numbers of regular diving ducks but did not find the Lesser Black-backed Gull reported earlier by the Sanders family. 

 

We continued on for quick visits to Horsecreek and Prospect Reservoirs (the latter will soon be frozen) but our most significant finds on that loop were a Merlin tending a large flock of Horned Larks and a sharp looking Rough-legged Hawk.

 

(as an aside, I will note that the afore mentioned, by Peter Gent, White-winged Scoter was still present, but over by the Baseline Reservoir dam by 4:00 p.m.)

[cobirds] White-winged Scoter, Boulder Co

All,

The was a female/immature plumaged White-winged Scoter on Baseline Reservoir at 1:30pm this afternoon.  It was east of where I parked on south Cherryvale Road, which is just southeast of Boulder.

At the Valmont overlook I ran into Christian Nunes, who had seen a juvenile Pacific Loon on Six Mile Res, which is immediately south of Boulder Res.  On Boulder Res he saw a Greater Scaup and a first-year male Barrow's Goldeneye.  All these birds escaped my gaze when I arrived there later.  Also, no white Geese at Dodd Res.

Cheers,  Peter Gent.

Boulder.
