Rufous Hummingbird
The rufous hummingbird (Selasphorus rufus) is a small hummingbird, about 8 cm (3.1 in) long with a long, straight and very slender bill. These birds are known for their incredible flight skills. Some are known to fly 2,000 mi (3,200 km) during their migratory transits.
The adult male has a white breast, rufous face, upperparts, flanks and tail and an iridescent orange-red throat patch or gorget. Some males have some green on back and/or crown. The female has green upperparts with some white, some iridescent orange feathers in the center of the throat, and a dark tail with white tips and rufous base.
The female is slightly larger than the male. Females and the rare green-backed males are extremely difficult to differentiate from Allen's hummingbird. This is a typical-sized hummingbird, being a very small bird. It weighs 2–5 g (0.071–0.176 oz), measures 7–9 cm (2.8–3.5 in) long and spans 11 cm (4.3 in) across the wings.
They feed on nectar from flowers using a long extendible tongue or catch insects on the wing. These birds require frequent feeding while active during the day and become [torpor|torpid] at night to conserve energy. Because of their small size, they are vulnerable to insect-eating birds and animals.
