Race curonicus migratory, but possibly resident in S breeding areas; W European population migrates across Sahara to tropics; leaves breading areas Jun to early Jul, and migrates late Jul to early Sept, reaching tropical Africa late Aug to Sept; returns from late Feb, reaching NW Europe from mid-Mar, peaking Apr to early May, and a month later in NE; along R Yenisey, return migration peaks late may. Siberian and other Asian populations migrate to SE Asia and India, where they mix with resident jerdoni; across Japan only on northward migration. Often migrates singly or in small flock often of not more than 10 birds. Nominate race resident and locally nomadic in Guinea; jerdoni resident, but moves about locally in response to water conditions.
