The ferruginous duck, also called the white-eyed pochard, is a medium-sized diving duck native to the Palearctic. The breeding male is rich dark chestnut on the head, breast and flanks, with contrasting pure white undertail coverts, and a white belly and underwing patch show in flight. Males have a yellow eye and females a dark eye, and females are duller and browner (Wikipedia, general species account).
It feeds mainly by diving or dabbling, taking aquatic plants with some molluscs, aquatic insects and small fish, often at night. Eggs are laid from the end of April or early May in a ground nest close to water, or a floating nest among emergent vegetation, and are incubated for 25 to 27 days. The sources opened say little about where it winters in South Asia.
