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.
Wedge-tailed Sabrewing
A large hummingbird (12-13 cm) found in humid foothill forests from southern Mexico to Guatemala. Green plumage with a wedge-shaped tail. Nectarivore of forest undergrowth, visiting Heliconia flowers. Named for its distinctively wedge-shaped tail.
