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.
Mexican Hermit
A medium-sized hermit hummingbird (13-14 cm) endemic to the Pacific slope of western Mexico from Nayarit to Oaxaca. Green plumage with buff underparts and long, white-tipped tail. Nectarivore of tropical dry and humid forests. Recently split from Long-billed Hermit.
