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 small, brilliantly colored hummingbird (8-9 cm). Males have a glittering ruby-red crown and golden-orange throat and breast, among the most vivid colors of any hummingbird. Found from Central America to Brazil and Trinidad. Nectarivore of open country, gardens, and forest edges.
