Migratory and dispersive, especially in N. After breeding, many make local movements to moult on large lakes and reservoirs; others moult on breeding waters. After moult, more marked movement towards coast; concentrations of up to 20,000 on Ijsselmeer, Netherlands, and 20,000 on Turkish coast of Black Sea; in C Europe and Australia many winter on large lakes. Thought to migrate following coast and also over land, but little known. No true migration in Africa, where extensive dispersal related to rains. In New Zealand local post- breeding dispersal; occasionally performs large scale-movements. Nominate race vagrant to Senegal and Taiwan; race australis accidental to Moluccas.   (del Hoyo J, Elliott A, Sargatal J (eds), 1992)
