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 hummingbird (12-13 cm) found in humid forests from southern Mexico to Bolivia and Brazil. Long, slightly decurved bill. Green plumage with a glittering blue-purple throat. Nectarivore of forest canopy and edges. Widespread Neotropical species.
