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 medium-sized hermit hummingbird (13-15 cm) found in lowland forests from Venezuela through Amazonia to Bolivia. Green plumage with a distinctive white beard-like throat stripe and long, white-tipped tail. Nectarivore of forest undergrowth, visiting Heliconia flowers.
