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.
Coppery-bellied Puffleg
A small hummingbird (10-11 cm) endemic to the eastern Andes of Colombia at 1,800-3,000 m. Males have a coppery-orange belly and white leg puffs. Nectarivore of cloud forest and forest edges. Classified as Vulnerable due to limited Colombian range and habitat loss.
