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.
Cockatiel
The cockatiel is the smallest member of the cockatoo family and one of the most popular pet birds globally. These gentle, intelligent parrots can learn to whistle tunes and mimic sounds. Wild cockatiels are nomadic, traveling in flocks following food and water availability across the Australian outback.
