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.
Great-billed Hermit
A large hermit hummingbird (15-17 cm), the largest in the genus, found in lowland Amazonian forests from Colombia to Brazil and Bolivia. Green plumage with a massive curved bill and long tail. Nectarivore of forest undergrowth, visiting large Heliconia flowers.
