Cobirds carries lots of reports about birds that people see, but hardly any about species that we don't see. I have queries on two:
Townsend's Solitaires: most winters, we have 2-5 on the hillside next to our home. This year, none to one (none for the last 3 weeks). Have they picked other sites, such as urban Denver, moved out onto the plains, gone south, stayed in the mountains, or really declined? Red-winged Blackbird: One of the people who reports to Denver Audubon's Backyard Birds commented that he'd seen fewer Red-wings in his yard this year than usual. Denver Audubon's monthly Walk the Wetlands recorded 142 in 2009; 71 in 2010. A localized phenomenon, or a widespread one? Christmas Bird Counts will give us data about these species, but they cover only a tiny part of our world. Any thoughts?
