Breeding in Eurasia, wintering to India, Middle East and Africa.

A very patchy range across Europe, widespread in Spain but found in scattered pockets from France east to the Baltic States and Poland, and south to Romania. More continuous in Belarus and Ukraine and east across Russia. Isolated outposts in southern Britain, central Sweden and southern Finland, Turkey and North-West Africa.

Extremely rare breeder in Britain with very small numbers present in summer and few successful nests. To the east range extends to northern Iran, Turkestan and Kazakstan, possibly into China in western Sinkiang.
