Broad-tailed Hummingbird

While writing my series of posts about our 2014 travels to the Southwest, I happened upon an old folder that contained hummingbird photos. I have yet to blog about a few of these species, including this Broad-tailed Hummingbird from Santa Fe on 23 May 2003 at the Randall Davey Audubon Center. The combination of the green crown and rose-red throat readily identifies this male. The proximity of males in flight also can be detected by the shrill, buzzing whistle made by the tips of their tenth primaries.

Broad-tailed hummingbirds breed in the southern Rocky Mountains, eastern California, and Mexico. At higher elevations, where they feast on wildflower nectar, they often go into torpor during chilly nights (Camfield et al. 2013). They usually avoid flowers that they have recently visited and will also take insects. Males make spectacular, swooping displays as their wings loudly buzz.
