I agree with Nick on the age and sex of the Boulder Bay-breasted Warbler. I would also like to thank Alan for finding this beauty and getting the word out.
Now, if someone would have told me 4 days ago this warbler would be in the same tree after all this time, I would have argued. Further, if someone had mentioned this behavior could be predicted, I would have laughed. The point being, our own Dave Leatherman has brought a new level of birding expertise to us and I would like to say Thank You to Dave for sharing his aphid fascination and it's impact on birds and birders.

These are in my recent bird pix gallery at www.pbase.com/quetzal. Update: I have heard that the 6 Lesser Black-backed Gulls are still loafing in the northwest corner of Horseshoe Lake in northeast Loveland. Comment on Ross's Goose: The photo is not the best, but the bill shape and head shape do not look right for Ross's Goose. I suspect hybrid Ross's x Snow Goose. Note the lack of a vertical edge to the base of the bill. Comment on the Bay-breasted Warbler: First, thanks to Alan Contreras for finding it, identifying it and sharing with the birding community. This bird has provided a rare Colorado learning opportunity for solving one of the greatest ID challenges (young Pine vs. Bay-breasted vs. Blackpoll Warblers in fall) as well as for understanding warbler foraging behavior. I have posted some comments on the ID features with my photos. I am thinking that this is a first fall male. Anyone disagree? Suggestion: Everyone walk outside, find a pine tree with moths and bees flying around it on this warm afternoon (indicating an aphid infestation), and then check the infested pine carefully for a happy warbler. I'll bet there are others out there. Nick Komar Fort Collins, CO -- You received this message because you are subscribed to the Google Groups "Colorado Birds" group.
