Hummingbird Study | July 17, 2018

Rufous Hummingbirds observed during Morning Birding with ACES.

Walking through the forest in and around Aspen, it is not unusual to hear the loud, high-pitched vibration of a male Broad-tailed Hummingbird whizzing past. The males of this species have specialized primary feathers that taper out and away from its body to create this sound, announcing its presence while aggressively defending its territory. The Broad-tailed “hummer” is commonly-recognized as our resident species, but is actually one of four hummingbird species that can be found in the Roaring Fork Valley.
