About These Birds
Speckled Hummingbird
A small hummingbird (9-10 cm) widely distributed in Andean cloud forests from Venezuela to Argentina at 1,000-3,000 m. Green plumage speckled with buff spots on the breast. Nectarivore of montane forest undergrowth and edges. One of the most widespread Andean hummingbirds.
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.
