[cobirds] Boulder County varia, Jan. 17-25

Hi, everybody. Just some notes of local interest, all from Boulder County:

Sun., Jan. 17, Boulder Creek downstream from Foothills & Arapahoe, an American dipper that meets David Leatherman's criteria.

Tues., Jan. 19, Erie Reservoir, the continuing ruddy duck, an even 100 canvasbacks, an unnatural gathering of ring-necked ducks (n=736, if anyone's keeping score), a prairie falcon, and an American coot with Tyrannosaurus rex genes.

Thurs., Jan. 21, Lake Park Open Space, Louisville, a western ["Woodhouse's"] scrub-jay at the eastern limit of its range, a vocal common merganser, and a white-breasted ["Nelson's] nuthatch giving the absolutely craziest vocalizations I have ever heard from a nuthatch.

Sat., Jan. 23, Boulder Creek upstream from the 75th Street bridge, a white-winged dove, a ruby-crowned kinglet, and a myrtle warbler.

Sun., Jan. 24, Mesa Trail complex, 14 dark-eyed ["white-winged"] juncos and a common raven giving a vocalization that I have come to think of as "the Boulder meme." I'm curious: Have any of you heard this vocalization away from the northern Front Range metro region?

Mon. Jan. 25, Greenlee Preserve, the continuing gray catbird and, suddenly, three brown creepers.
