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.
Reddish Hermit
A tiny hermit hummingbird (7-8 cm) found in humid forests from the Guianas through Amazonia to Brazil and Bolivia. Rufous-brown plumage overall with a curved bill. Nectarivore of dense forest undergrowth. Visits tiny flowers near the forest floor. One of the smallest hermits.
