Wings have a brown, black and white pattern visible in flight. Tail is white with black terminal band. Legs are orange. Sexes are similar.

Range and Habitat

Ruddy Turnstone: This species breeds on the coastal tundra habitats of northwestern Alaska, on the islands of Canadian Arctic, and northern coastal Greenland. Spends winters on coasts from Connecticut and Oregon southward to the Gulf Coast and also coastal areas of the West Indies; also found in Eurasia.

Breeding and Nesting

Ruddy Turnstone: Two to four olive to olive buff eggs marked with brown and black are laid in a ground hollow lined with bits of grass and dead leaves, often built under a low bush. Incubation ranges from 21 to 23 days and is carried out by both parents.

Foraging and Feeding

Ruddy Turnstone: They mainly feed on insects, particularly midges, and some plant material in the summer. They also eat mollusks, crustaceans and carrion in the winter. They probe and dig using their bill, overturning objects such as stones, mollusk shells and seaweed with rapid jerks of the head to reveal prey, which are then quickly jabbed or pecked and eaten.
