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.
Marvelous Spatuletail
One of the world's most extraordinary hummingbirds (10 cm body, males with 15 cm tail rackets). Males have two extremely long outer tail feathers ending in large, iridescent violet-blue discs. Endemic to a tiny area of northern Peru. Critically Endangered. Fewer than 1,000 individuals.
