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.
Velvet-browed Brilliant
A medium-sized hummingbird (12-13 cm) found in tepui highlands of southern Venezuela and adjacent Guyana. Green plumage with a velvety dark forehead. Nectarivore of tepui forest edges. A Pantepui endemic of very restricted range. Poorly studied.
