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.

A large hummingbird (12-13 cm) endemic to the coastal mountains of northern Venezuela at 900-2,500 m. Males have a striking violet-blue breast. Nectarivore of montane forest and coffee plantations. A range-restricted Venezuelan endemic.
