Rufous hummingbird

The rufous hummingbird (Selasphorus rufus) is a small hummingbird, about 8 cm (3 in) long with a long, straight and slender bill. These birds are known for their extraordinary flight skills, flying 3,200 kilometres (2,000 miles) during their migratory transits. It is one of nine species in the genus Selasphorus.

The adult male has a white breast, rufous face, flanks and tail, and an iridescent orange-red throat patch or gorget. Some males have some green on their back and/or crown. The female has green, white, and some iridescent orange feathers in the center of the throat, and a dark tail with white tips and a rufous base.

The female is slightly larger than the male. Females and the rare green-backed males are difficult to differentiate from Allen's hummingbird. The typical "notched" shape of the second rectrix (R2) is considered an important field mark to distinguish the adult male rufous hummingbird from the adult male Allen's hummingbird. This is a typical-sized hummingbird, being a small bird. It weighs 2–5 g (1⁄16–3⁄16 oz), measures 7–9 cm (3–3+1⁄2 in) long and spans 11 cm (4+1⁄2 in) across the wings.
