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.
Chestnut-breasted Coronet
A medium-sized hummingbird (11-12 cm) found in Andean cloud forests from Peru to Bolivia at 1,500-2,800 m. Green plumage with a chestnut breast band. Nectarivore of montane forest and forest edges. Replaced by Buff-tailed Coronet north of Peru.
