Baikal Teal

The Baikal teal, also called the bimaculate duck or squawk duck, is a dabbling duck that breeds in eastern Russia and winters in East Asia. It is slightly larger and longer-tailed than the common teal, 39–43 cm long and averaging about 500 g. The breeding male is unmistakable, with a striking green nape, yellow and black face patches, neck and throat, a dark crown, a light brown spotted breast, and grey sides set off by white bars front and rear (Wikipedia, general species account).

In non-breeding plumage the drake looks more like the female but is a much richer rufous. It breeds within the forest zone of eastern Siberia, from the Yenisey basin east to Kamchatka. The cached account gives no detail specific to India. SoIB 2023 lists it as a winter migrant of wetlands that eats plants and seeds, and does not assign a priority category (Wikipedia, general species account; SoIB 2023).
