This is a monotypic species[1].


Swamps, lakes and marshes.



They feed by dabbling; the diet includes water plants and insects.


The eggs are laid in the nests of other birds. The hosts are usually Rosy-billed Pochard but the nests of many other ducks, and even gulls or birds of prey are used. The existing clutch remains unharmed. After a 21-day incubation, the ducklings fledge a few hours after hatching immediately becoming completely independent.
