Montagu's Harrier

Montagu's harrier breeds in large open areas across the Palearctic and is migratory, wintering in Africa, the Indian subcontinent and parts of the Arabian Peninsula. The sexes differ strongly. Adult males are pale grey with black wingtips, black bands along the secondaries above and below the wing and rusty streaks on the belly and flanks. Females are mostly pale yellow-brown below with a dark brown back and a white rump (Wikipedia, general species account).

The name commemorates the British naturalist George Montagu.
