Long distance migrant. seems to be restricted to few stopover sites along flyways; highly faithful to wintering sites. Migration largely offshore and coastal, but locally frequent inland across Africa and North America; also occurs on many small oceanic islands. birds from Greenland and Siberia (E to Taymyr) pass through British Is, some staying there, but most winter down continental coasts from Europe S to S Africa; evidently loop migration, as in spring some birds from W Africa cross Sahara to C Mediterranean. Siberian birds E of Taymyr move down E Russian coast or overland, to Indian Ocean and SW Pacific; in E Asia, common migrant through Korea, E China and Japan, and also through Vietnam and Cambodia. Birds wintering in SE Asia and Australia probably originate from New Siberian Is. Nearctic birds move along Pacific and Atlantic coasts and via prairies and Texas coast; most abundant on Pacific coast of South America, whence N migration mainly via inland and Atlantic routes; high numbers staging at Delaware Bay, probably mostly from Brazil; Pacific North American winterers migrate along Pacific coast. Many 1-year-olds apparently return to breeding grounds, but some remain S all year.   (del Hoyo J, Elliott A, Sargatal J (eds), 1996)
