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.
Green Hermit
A large hermit hummingbird (15-17 cm) found in humid montane forests from Central America to Peru at 400-2,000 m elevation. Brilliant green plumage with dark face mask and long, white-tipped tail. Nectarivore of forest undergrowth, visiting Heliconia and Passiflora flowers.
