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.
Scale-throated Hermit
A medium-sized hermit hummingbird (14-15 cm) found in the Atlantic Forest of southeastern Brazil, northeastern Argentina, and eastern Paraguay. Green plumage with scaled throat pattern and long, white-tipped tail. Nectarivore of forest undergrowth and edges.
