Circus macrourus (SG Gmelin, 1770)
Family: Accipitriformes > Accipitridae
Similar to but paler than a Hen Harrier, with fewer black primaries, this is a very rare visitor from eastern Europe.
Most records concern juveniles seen in autumn and some remain through winter. Identification is complicated by the presence of Hen×Pallid Harrier hybrids.
Harriers are stunning, lithe and elegant birds of prey. Two species of grey harrier are regularly found in the UK, Hen and Montagu's - the males are relatively easy to separate, but the females and young birds can be more tricky.
