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.
Black-throated Brilliant
A medium-sized hummingbird (11-12 cm) found in humid forests from eastern Colombia through Ecuador and Peru at 300-1,500 m. Males have a black throat patch with green glitter. Nectarivore of foothill forest. Named after the Austrian naturalist Carl von Schreibers.
