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.
Giant Hummingbird
The world's largest hummingbird (21-23 cm, weight 18-24 g), roughly the size of a European Starling. Green-brown plumage. Found in open habitats along the Andes from Colombia to Chile and Argentina at 2,000-4,500 m. Nectarivore of cacti and large flowers. Unusually slow wingbeat for a hummingbird.
