I checked on this redpoll flock between 1 and 2 pm, and the flock has apparently increased in size to 40+. I received a tip about a pale one and indeed there were some birds at the pale end of the Common Redpoll spectrum. I will look at my photos to see if any may appear too pale for the Common Redpoll spectrum, and possibly within the Hoary Redpoll spectrum. I might add that my reading of the species accounts in Birds of North America Online confirmed my suspicion that there is no distinct delineation of the Common and Hoary Redpoll spectrums (spectra?), and that the taxonomic relationship between these two species with overlapping morphology (i.e. appearance) is uncertain. Essentially birds farther north and farther east are palest.
Nick Komar Fort Collins CO From: Eric DeFonso Sent: Sunday, December 23, 2012 12:53 PM To: cobirds@googlegroups.com Subject: [cobirds] Common Redpolls, Larimer Hi all, The Common Redpolls reported by Sparks last week were still present at the feeders behind the Discovery Museum in Fort Collins. It wasn't obvious how many individuals are in the flock (or "gallup", which is what iBird pro says is the correct term for a group of them) - at any time there were a half dozen at the feeders - but I'd guess that there are at least a full dozen hanging around, and perhaps more. They were pleasantly easy to find around 9am this morning. -- Eric DeFonso Boulder, CO -- You received this message because you are subscribed to the Google Groups "Colorado Birds" group.
