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.
Sapphire-bellied Hummingbird
A medium-sized hummingbird (10-11 cm) endemic to northern Colombia. Males have a sapphire-blue belly. Nectarivore of mangroves and dry forest. Critically Endangered with a very small population restricted to a tiny area of Caribbean Colombia.
