I just spent 3 days at our place above Collbran (8400ft) where the hummers usually drain our feeders about every 2 hrs or so this time of year. We filled them Friday night and dumped them out Sun night. I checked 9 years of records and the only other time hummers were low (not this low) was another wet year with late blooming. I spent most of the time in the woods either on this property or nearby and I was rarely out of sight or earshot of a broad-tailed. I suspect nesting is late--so fewer females and no juveniles at the feeders yet, and with so much blooming so profusely with many, many insects, the feeders just aren't so attractive. I think they are here, but life is easy so why fight over some feeders? I'd be interested if others suspect fewer birds, but I think they are here.
Other population notes (1) I saw no black-capped chickadees. I have some 30-odd lists for visits to this property in May/June. Every year I've had black-capped chickadees. This year, not a single one. (2) On the other hand, I have Swainson's thrushes everywhere. Some years I didn't record any and when I did there never seemed to be many. Either they are much more vocal this year or they've found this place a lot more attractive than in the past.
