Leon's report on the increase of Calliope Hummingbirds is reflected at my yard in Niwot. Fifteen minutes ago there were four Calliopes at my flowers in the front yard and two more at feeders in the back yard. It's been this way for the last two weeks.

COBirders,
Here is an anecdotal report on this season's hummingbird numbers coming to our cabin's numerous feeders at 9200' in the Sangre de Cristo range. As compared to the last three decades, the overall numbers to visiting hummers are up considerably, led by a very good crop of juvie Broadtails. I credit the favorable weather conditions for being responsible for the increase for these local breeders. The number of Rufous hummers is possibly above average with about normal ratio of adult males to those with female/juvenile plumage. The most interesting story is that of the increased presence of Calliopes, especially females and juvies. I would estimate that surge at about 30% to 40% this year. At this point I'm not informed of the conditions at their breeding grounds in the Pacific Northwest that would account for this upswing.
