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.
Green-fronted Lancebill
A medium-sized hummingbird (11-12 cm) with a remarkably long, straight bill (40 mm). Green plumage with a violet-blue forehead. Found in Andean cloud forests from Costa Rica to Bolivia at 800-2,500 m. Named lancebill for its dagger-like bill used to pierce the base of long tubular flowers.
