A medium-sized hummingbird (9-10 cm) found in arid coastal lowlands of western Peru and Ecuador. Green plumage with variable rusty-orange underparts. Nectarivore of desert scrub, gardens, and river valleys. Adapted to arid Pacific environments.
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.

Their body temperature can drop to near ambient at night to conserve energy.
