Indian Spot-billed Duck
Anas poecilorhyncha
This duck is around the same size as a mallard and has a scaly patterned body with a green speculum bordered by white. At rest the white stripe stands out and the long neck and the bill with yellow tip and orange red spots at the base are distinctive in the nominate subspecies. In flight it is distinguished by the green speculum with a broad white band at the base. The red spots at the base of the bills are absent in haringtoni. It measures 55–63 cm (22–25 in) in length and 83–95 cm (33–37 in) across the wings, with a body mass of 790–1,500 g (1.74–3.31 lb).
