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 small hummingbird (9-10 cm) endemic to the Pirre massif of eastern Panama at 700-1,500 m. Green plumage. Nectarivore of cloud forest. An extremely range-restricted Panamanian endemic found only on Cerro Pirre and adjacent peaks.
