Migratory and sometimes partially migratory, but movements in various low Arctic and N temperate regions unclear. Non-breeding range extends further N than in other Calidris, to just below ice, e.g. SW Greenland, Finnmark and Murmansk, and S to Maryland (USA) and W France. Northernmost breeders fully migratory. Easternmost breeders migrate W to Murmansk or beyond. Unclear whether breeders at S of range are replaced by N breeders or N breeders show leap-frog migration, wintering S of S breeders. E Greenland breeders believed to winter in Iceland. Birds breeding in W Greenland winter in W & S Greenland. Ringing recoveries indicate migration between W Europe and Iceland, Greenland, Newfoundland and Baffin I, and between Norway and Britain. Post breeding migration later than in other Calidris species; females depart breeding grounds in advance of males and young, from Iceland in late Jun; males in Iceland until late Aug, and on Arctic islands from late Aug to mid-Sept. Arrival in North Sea and Iceland Oct-Nov. N movement Apr-May, and arrival in N breeding grounds mid-May to mid-Jun.   (del Hoyo J, Elliott A, Sargatal J (eds), 1996)
