Occurs across Europe, Asia and North America, widespread and fairly common over much of the Western Palearctic.

Breeds in Britain and Ireland, and from Iberia east to the Urals and Caspian, north to central Norway coast and head of the Gulf of Bothnia. Found south to the north Mediterranean coast from southern Spain to Greece and breeds on Balearics and at a few scattered sites in Turkey. Also breeds in the Azores and Canary Islands and rarely in North-West Africa. First breeding record for Egypt in 1987 and may breed at scattered sites in the Middle East.

Northern birds are mainly migratory, leaving breeding areas in October-November to winter in western and southern Europe, and returning in March-May, those further south are resident with some dispersal of young birds.

Vagrants recorded on Svalbard, Bear Island, Iceland and the Faroes to the north, and to the south in Kuwait and Iraq.
