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 large hummingbird (12-13 cm) widely distributed from Panama through South America to Argentina. Males have a velvety black throat bordered by blue-green. Long, curved bill. Nectarivore of forest edges, gardens, plantations, and open country. One of the most adaptable mangos.
