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.
Cinnamon-throated Hermit
A small hermit hummingbird (10-11 cm) found in dry scrubland and gallery forests of central Brazil and eastern Bolivia. Cinnamon-orange throat, green upperparts, and rufous underparts. Nectarivore adapted to cerrado and transition forest habitats.
