Most populations (except on the Atlantic islands) are short-distance migrants, wintering south to the Sahel region of Africa from Senegal east to Sudan, and southwest Asia east from Saudi Arabia to northwestern India.

A vagrant north of the breeding range to northwestern Europe, with e.g. 45 records in Britain, eight records in Germany, four records in Denmark, and one record in Ireland.
