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.
Glowing Puffleg
A small hummingbird (10-11 cm) found in Andean cloud forests from Venezuela to Peru at 2,400-3,500 m. Bright green plumage with conspicuous white leg puffs. Nectarivore of montane forest and gardens. One of the most common and widespread puffleg species.
