Circus aeruginosus

Mainly migratory in N & E Europe and C Asia; sedentary and dispersive in S of breeding range. N breeders winter from France and N Africa through Mediterranean to Turkey, Middle East and Nile Valley, and S to sub- Saharan Africa; easternmost Asian populations winter in Indian Subcontinent and Sri Lanka; also said to winter in SE China and Greater Sundas, but considerable confusion in this zone with C. spilonotus. Migrants start to arrive on breeding grounds in Mar, or Apr in N of range; leave mainly in Sept-Oct, although juveniles start dispersal earlier.
