CCRobust, compact and dark wader, with relatively long and slightly curved bill. Mostly seen in winter at the coast where it prefers rocky surfaces as opposed to most other waders. In winter plumage the base of bill and legs are yellow, and the upperparts grey with dark markings. Breeds in high Arctic and mountains. Summer plumage darker than winter, with brown fringes/spots on back, and darker bill and legs. Similar wing and rump pattern to Dunlin, but appears overall darker. Tail extends beyond wing tips of resting birds. Flight patterns at wintering grounds straight and low.
Sound:Contact call a hoarse and hard "weet". Sometimes in chattering series. Song quite varied with series of short, nasal, vibrating sounds, interspersed with drawn out, slower calls.
