It supports both aground and in water. Aground, it contacts and takes natural frightening little creatures. In shallow water, it swims, delays and swims, supporting on plant matter, for instance, seeds of grasses, sedges and maritime plants. It in like manner gets land and water proficient gutless animals.
In the midst of the dry season, they amass in greater groups at enduring waters. A short time later, the sets outline toward the beginning of the stormy season.

The particular folks routinely perch in trees from where they watch the gatherings, and they swoop down to mate with a female.
The Knob-charged Duck is fundamentally stationary in its range. Customary improvements and scatterings happen, as showed by the water openness.
FLIGHT:
The Knob-charged Duck is a conventional flier. It performs direct, anyway tireless and clamorous wingbeats.
When they move to find water, they fly in capricious advancement, or in single-record lines, or in V-game plan.
Multiplication:
The raising season generally occurs in the midst of and after the stormy season.
The Knob-charged Duck consistently breeds in openings in dead trees, in the region of 6 and 9 meters over the ground and once in a while, decently far from water. They in like manner settle now and again on the ground in tall grass or among stones close water, or in pit in bank or divider. As a general rule, a comparable home site is used an apparently interminable measure of time.

Protection/THREATS/STATUS:
The Knob-charged Duck is still comprehensively passed on, and has broad people in Africa. In any case, this species is in all probability declining in Asia;
The race "sylvicola" is surveyed as "close undermined".
The two races are undermined by deforestation, use of lethal substance in ricefields in S America where it is seen as a bothering, and overhunting in Madagascar.
In any case, this species isn't right presently thoroughly undermined
