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.
亚马逊鹦鹉
The turquoise-fronted amazon is one of the most popular pet parrots in the world, prized for its ability to mimic human speech and its engaging personality. In the wild, these sociable parrots roost communally in large flocks and fly in pairs to feeding sites at dawn. Habitat loss and trapping for the pet trade threaten wild populations.
