BROAD-TAILED HUMMINGBIRD

A common hummingbird of the Rockies, the Broad-Tailed Hummingbird male is easily told from the Ruby-Throated by a distinctive shrill metellic, wing whistling. However the whistling begins after the first full year. Males have  a wide rounded tail and a rose-colored throat. There are no other western hummingbirds with a green crown and tail, and a solid red throat.  The Broad-Tailed female looks very similar to the female Rufous and Allen's.
