Grey-headed Lapwing

The grey-headed lapwing is 34–37 centimetres long. As the name says, it has a grey head and also a grey bill. The breast is striped dark grey and the belly white, the back is brown, the rump white and the tail black. In flight it is especially recognisable by black primaries, white under the wings and on the secondaries, and brown wing coverts. Adults of both sexes look alike, though males are generally larger. Juveniles have less pronounced breast stripes and pale fringes on the upperwing and coverts. (French Wikipedia, general species account)

It breeds mainly in Manchuria, but also on the island of Honshu and the east coast of China, and occurs occasionally in Russia, the Philippines, Indonesia and Australia. Continental populations winter in northeast India and Cambodia, while birds in Japan migrate, at least partly, to southern Honshu. It is gregarious, laying from April to July in wet meadows, rice fields or the edges of marshes, and feeds on insects, worms and molluscs caught in shallow water.
