The population leaves for its winter quarters between September and October, returning to the breeding areas towards February. Pre-migratory dispersal can occur, with movements from natal colonies averaging 200 km, usually northwards, before starting the southward migration.

After breeding and before the autumn migration to Africa, there is a positive selection for stubble cereal fields, fallow and margins of cultivated land; a period poorly understood but probably of great importance to juvenile survival.
