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-vented Puffleg
A small hummingbird (11-12 cm) found in Andean cloud forests from Colombia to Bolivia at 2,500-3,800 m. Green plumage with sapphire-blue vent and white leg puffs. Nectarivore of montane forest and páramo edges. Relatively common along the Andes.
