Grey-winged Blackbird

The Grey-winged Blackbird male has black plumage on head, neck, back and top of underparts. The lower underparts are black with weak greyish scaled effect.
The upperwing shows conspicuous greyish-white panel. The wing-coverts have whitish tips. The tail is black. The bill is orange-yellow. The eyes are dark brown surrounded by narrow whitish eye-ring. Legs and feet are yellowish-brown.
The female is very different with pale olive-brown plumage. The wing-coverts are brown with broad buffy-white tips. The back is slightly darker with buff-tipped feathers, involving weak scaled effect.
The Grey-winged Blackbird breeds at high elevation, between 1800 and 2700 metres in the Himalayas. It breeds in humid evergreen forest including diverse tree species.
It winters in dry scrubs, bush jungle, open forest, clearings and forest edges, and can be seen near habitations around villages. It is visible up to 2600 metres of elevation.
But it usually reaches lower elevation in winter according to the region.The Grey-winged Blackbird occurs in the Himalayas, S China and N Indochina. Non-breeding birds are occasionally seen in Myanmar and NW Thailand.
The Grey-winged Blackbird feeds mainly in trees, searching for preys in moss on the branches. But it also forages on the ground, performing rapid hops alternated with pauses, as most Turdidae species do. It feeds on insects and larvae, and caterpillars. It also takes snails, earthworms and slugs. Fruits and berries from Cotoneaster and Berberis are also consumed and taken in fruiting trees. During the winter, they often forage in small flocks.
