The Black-headed Duck is a small, teal-sized duck found in temperate South America. This species is unique among ducks in that it is an obligate brood parasite. In its interactions with its host species, Black-headed Ducks procure the services of incubation from the host; as a precocial species, parental care provided newly-hatched ducklings is minimal since Black-headed Duck young soon leave host broods.
