Eastern Marsh-Harrier

The eastern marsh harrier is a bird of prey of the marsh harrier group, 48–58cm long with a wingspan of 113–137cm, the female usually larger. The male's plumage is variable: typically the head, breast, back and wing coverts are blackish with pale streaks, the rest of the wing grey with black tips and a white front edge, the tail grey, the rump white and the underparts mostly white. Young birds are dark brown with buff on the head and a pale patch on the underwing (Wikipedia, general species account).

Its wintering range includes southern China, Taiwan, Korea, southern Japan, north-east India, Bangladesh and South-east Asia as far south as the Philippines, Borneo and Sumatra. Four to seven eggs are laid and incubated for 33–48 days, and the young fledge after 35–40 days. It is usually silent but has a mewing call, most often at roost sites (Wikipedia, general species account).
