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.
Butterfly Coquette
A tiny hummingbird (7-8 cm) found in humid forests from Venezuela and Colombia to Peru and Bolivia. Males have wispy green cheek plumes and a white breast band. Nectarivore of forest edges and clearings. Named for the French ornithologists Jules and Edouard Verreaux.
