The lesser whistling duck (Dendrocygna javanica) is a species of whistling duck that can be found inhabiting wetlands and marshy fields in Asia, mostly in India and its surrounding countries. This duck can be identified due to its two-toned, whistling call and its distinct warm brown appearance which sets it apart from other whistling duck species.
They can be seen flocking in small groups during the daytime, waddling along the shallow marshes, and picking at mud in order to find worms and other creatures. They eat their fill of rice grains from paddy fields as well, making them omnivorous in nature.
They are also nocturnal feeders, feeding in the dark before retiring to their tree cavity nests or branches.
Though they are known to look very similar to their larger cousin, the fulvous whistling duck, they can be told apart by their size and the color of their rumps, with the lesser whistling duck species being smaller and having a chestnut-colored rump as opposed to the fulvous duck's cream-colored one.
