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-vented Plumeleteer
A medium-sized hummingbird (11-12 cm) found in humid forests from Panama to Venezuela and Ecuador. Green plumage with white vent. Feathered leg puffs. Nectarivore of forest undergrowth. Named after the French naturalist Buffon.
