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.
Minute Hermit
A tiny hermit hummingbird (6-7 cm), one of the smallest in its genus. Endemic to the Atlantic Forest of eastern Brazil. Green plumage with rufous underparts and a short, curved bill. Nectarivore of low forest undergrowth. Classified as Near Threatened due to habitat loss.
