Distribution / Range

It is largely resident, apart from dispersion in the wet season, but Chinese birds winter further south. It nests in tree holes, laying 8-15 eggs.

This is an abundant species in Asia, although the slightly larger Australian race appears to be declining in numbers.

Found on all still freshwater lakes (jheels), rain-filled ditches, inundated paddy fields, irrigation tanks, etc. Becomes very tame on village tanks wherever it is unmolested and has become inured to human proximity.

Swift on the wing, and can dive creditably on occasion.
