[cobirds] 71st Boulder CBC, Sunday, 16 Dec.

Folks- scores of volunteers fanned out across 30 territories yesterday for the 71st iteration of the Boulder CBC. It will be a while before the tally is final, but we have a preliminary 109 species found on the count, with three more ticked for count week. We added one species to the historic total, with the long-staying Northern Cardinal in NW Boulder marking #210 for the count. Other birds judged scarce as being seen 10 or fewer previous times on the count included Clark's Grebe, Barn Owl, Marsh Wren, and Common Grackle (10 prior), Fox Sparrow (9 prior), Tundra Swan (6 prior, the 8 birds previously at Baseline Res seen at Valmont yesterday), Lesser Black-backed Gull and Northern Saw-whet Owl (5 prior), Chihuahuan Raven and Golden-crowned Sparrow (3 prior), and Common Yellowthroat (2 prior.) Birds seen on at least half the Boulder counts but not found yesterday (to my knowledge so far) include Rough-legged Hawk (seen on 58 prior counts), Ring-necked Pheasant (53 prior), Cassin's Finch (46 prior), Clark's Nutcracker (44 prior), and Red Crossbill (35 prior.) The Boulder foothills have a very poor cone crop this year. Finally, I think we will exceed triple digits for Common Redpoll, likely setting a high count for the Boulder Count (though currently I can't get the re-tooled Audubon site to give me historic results…

Thanks to all of the leaders, participants, and feeder-watchers for another successful Boulder CBC!

Enjoy- Bill Schmoker, Longmont
