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.
Long-tailed Hermit
A large hermit hummingbird (15-17 cm) found in humid lowland forests from Venezuela through the Guianas to northern Brazil. Green plumage with long, curved bill and very long, white-tipped central tail feathers. Nectarivore of forest undergrowth. Males gather in singing leks.
