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 hermit hummingbird (10-11 cm) found along the Tapajós River basin in central Brazil. Green plumage with rufous underparts. Nectarivore of forest undergrowth. Recently described as a species distinct from other Phaethornis hermits based on vocal and plumage differences.
