Lesser Whistling Duck

The lesser whistling duck is a long-necked chestnut-brown duck about 38–42 cm long. Both sexes look alike, with a dark crown, yellow to orange eye-ring, broad rounded wings and chestnut upper-tail coverts; the last feature separates it from the larger fulvous whistling duck's pale rump. Flocks give loud, wheezy two-note whistles in flight and often circle with rapid wingbeats before settling (Wikipedia, general species account).

A widespread resident of lowland South and Southeast Asia, it gathers on lakes, marshes, flooded fields and rice paddies. Birds rest communally by day, sometimes perching in trees, and feed mainly after dusk on aquatic plants, seeds, grain, molluscs and small aquatic animals. Nests may be placed in tree hollows or dense vegetation near water. Clutches usually contain seven to twelve eggs, incubated for around 22–24 days (Wikipedia, general species account).
