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.
White-browed Hermit
A small hermit hummingbird (10-11 cm) found in Andean foothill forests from Peru to Bolivia at 800-1,800 m elevation. Green plumage with white eyebrow stripe and buffy underparts. Nectarivore of cloud forest undergrowth. Named after the Austrian naturalist Karl Stuart.
