Lesser Whistling Duck
The lesser whistling duck (Dendrocygna javanica), also known as Indian whistling duck or lesser whistling teal, is a species of whistling duck that breeds in the Indian subcontinent and Southeast Asia. The species also occur on islands in the region including the Andamans, Nicobars and Maldives.
They are nocturnal feeders and during the day they can be found in flocks around lakes and wet paddy fields. They can perch on trees and sometimes build their nest within their hollows. This brown and long-necked duck has broad wings that are visible in flight and produces a loud two-note wheezy call. It has a chestnut rump, differentiating it from its larger relative, the fulvous whistling duck, which has a creamy white rump.
