They’re often migratory, especially S populations.
Feed by dabbling on water surface, upending in shallow water. Also graze on land.
Courtship displays involve exaggerated drinking/mock preening/head bobbing/neck extending.
Females lay 8-14 eggs per clutch & often lay eggs in other bird’s nests if available, including those of other females. Broods of different females sometimes merge w/ females raising ducklings collectively. Males sometimes play parental role but often abandon females after mating.
Nests often parasitized by Black-Headed Ducks, meaning female Rosybills often raise Black-Headed ducklings as well as own ducklings.
Ducklings leave mom at 3 months old & become sexually mature at 10 months old.
Nests often built over water at water’s edge.
Usually breed in October & November.
Fun Fact(s):
Sometimes hybridize w/ other pochard species in captivity.
They can be quite tame.
In areas where hunted, they’re prone to swallowing lead bullets due to mistaking them for stones required for mechanical breakdown of food within gizzard.
Commonly used by people for consumption, pets, display animals, & in horticulture.
Sometimes persecuted due to being pests in rice fields.
Scientific name means “showy-winged duck.”
