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.
Hoary Puffleg
A small hummingbird (10-11 cm) found in cloud forests of the western Andes of Colombia and Ecuador at 1,200-2,400 m. Dark green plumage with white leg puffs. Nectarivore of wet, mossy cloud forest. Classified as Near Threatened due to Chocó forest habitat loss.
