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.
Black-crested Coquette
A tiny hummingbird (7 cm) found in humid forests from southern Mexico through Central America to Belize and Guatemala. Males have an elongated black crest and white tail-band. Nectarivore of forest undergrowth and edges. Uncommon and inconspicuous.
