About These Birds
Anna's Hummingbird
Anna's hummingbird is the most common hummingbird along the Pacific coast and one of only three species resident in the United States year-round. Males perform spectacular dive displays, plummeting from 40 meters and pulling up with a loud chirp produced by tail feathers. Their body temperature can drop to near ambient at night to conserve energy.

A spectacular small hummingbird (10-11 cm) endemic to the cerrado of central Brazil. Males have two erect, horn-like iridescent violet-blue feather tufts projecting from the sides of the head. Green and white plumage. Nectarivore of cerrado flowers. The only member of its genus.
