Small, sprightly shorebird. Breeding plumage shows rusty tones on upperparts, often with a frosty appearance when fresh. By mid-summer, the frosty feather tips fade away and the neck can be deep, rich red—not to be confused with the much smaller Red-necked Stint! Very pale in winter. Juveniles are nearly spangled with black-and-white above. At all seasons, note larger size and somewhat thicker bill than other peeps or stints, along with bold white wing stripe in flight. Flocks are usually seen on open beaches, well known for running back-and-forth chasing waves and feeding actively in the sand. Also occurs on mudflats, especially in migration. Extensive global range, breeding on high Arctic tundra and wintering on coastlines on every continent except Antarctica.
