The rufous hummingbird (Selasphorus rufus) is a small hummingbird of the Trochilidae family. It is about 8 cm (3.1 in) long with a long, straight and slender bill. These birds are known for their extraordinary flight skills, flying 2,000 mi (3,200 km) during their migratory transits.
Their primary breeding habitats are open areas, mountainsides and forest edges in western North America from southern Alaska through British Columbia and the Pacific Northwest to California, nesting further north (Alaska) than any other hummingbird.
They feed on nectar from flowers using a long extendable tongue or catch insects on the wing. These birds require frequent feeding while active during the day and become torpid at night to conserve energy. Because of their small size, they are vulnerable to insect-eating birds and animals.
