[edit] Breeding

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.
