Ruddy shelduck (Tadorna ferruginea) swimming happily in a lake at Jurong Bird Park, Singapore
The Ruddy Shelduck is a member of the duck, goose and swan family Anatidae. In Bangladesh it is known as Chokha. Distinct categorization is not easy as this bird falls somewhere between ducks and geese in size. They are found across central Asia to southeast China. These birds are mostly migratory, wintering in southern Asia. This lovely waterfowl has cinnamon body plumage and a paler head. The wings are white with black flight feathers. It swims well, and in flight looks heavy, more like a goose than a duck. The male has a black ring at the bottom of the neck in breeding season, and the female often has a white face patch. The call is a loud wild honking. Feeds mostly on plant material and also invertebrates. Found both in small and big flocks on the landmasses in partly dried up rivers during winter in Bangladesh albeit, far away from human habitats.
