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 hummingbird (9-10 cm) found in southeastern Brazil. Males have a purple-violet crest. Nectarivore of Atlantic Forest edges and secondary growth. Recently split from Green-crowned Plovercrest. An Atlantic Forest near-endemic.
