Twisting and turning on long, angular wings, this relative of the sandpipers and plovers gives a swallowlike impression in flight. Adults are brown overall with an elegant black necklace and pale yellow throat. When in flight, note dark flight feathers, chestnut underwing coverts, bright white trailing edge to the wings, and a flashing white rump. Juveniles are a mottled gray-brown above and lack the adult's necklace. Flight call a harsh “tarrack.”
