Migratory. Departure from breeding grounds from early Aug onwards, and wintering on flooded grasslands in African regions just after rainy season. Migrates across Turkey and down R Nile to Ethiopian plateau, arriving Aug-Sept; only rare passage visitor in Egypt, late Aug to late Oct and early Mar to mid-Apr. In Ethiopia, large numbers stay until grasslands dry up in Oct, whereafter they move S & SW, following the rains; recorded in Kenya, SW Tanzania, Malawi, Zambia, Zaire, Zimbabwe, Namibia and South Africa from mid-Oct; 5000- 10,000 birds have been counted in Mali, in Nov. High numbers probably migrate to wetlands along Gulf of Guinea where thy stay Aug-Dec; as wetlands dry up, theses birds migrate to other, undetermined areas in Africa; moult data suggests that these birds constitute separate population. Northward migration occurs in broad front over Africa Mar-Apr, and probably oriented more to W, crossing Mediterranean, but northward migration passes largely unnoticed; males arrive in Ukraine before females; arrives on R Yenisey in early Jun. Irregularly, some birds winter in NW Europe and S Scandinavia.   (del Hoyo J, Elliott A, Sargatal J (eds), 1996)
