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 slender, elegant hummingbird (11-13 cm) with a long, deeply forked tail. Green upperparts, purple crown, and immaculate white underparts. Found in humid forests from southern Mexico to western Ecuador. Nectarivore of forest canopy. Named fairy for its delicate, floating flight.
