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.
Птица-секретарь
The secretary bird is the only raptor that hunts primarily on foot, striding through grasslands on crane-like legs up to 1.2 meters tall. Its name may derive from the crest feathers resembling quill pens tucked behind a secretary's ear. The species is classified as Endangered due to habitat loss and decline across much of its range.
