About These Birds
Mangrove Hummingbird
A medium-sized hummingbird (10-11 cm) endemic to the Pacific coast of Costa Rica, restricted to mangrove forests. Green plumage. Nectarivore specializing in mangrove flowers (Pelliciera rhizophorae). Classified as Endangered due to mangrove habitat loss.
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.
