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.
Pale-bellied Hermit
A medium-sized hermit hummingbird (12-14 cm) found in dry forests and scrublands of Colombia, Venezuela, and Panama. Pale belly, green upperparts, and a long curved bill. Nectarivore of dry forest undergrowth and edges. One of the few hermits adapted to arid habitats.
