Notes on Black-headed Ducks, Painted Snipe and Spotted Tinamous.

One aberrant species, the Black-headed Duck, is an obligate brood parasite, laying its eggs in the nests of gulls and coots.

The only member of the genus Nomonyx, it is intermediate between the rather primitive Black-headed Duck (Heteronetta) and the very apomorphic true stifftails.

The Black-headed Duck of Heteronetta is indisputably quite basal, looking more like a typical ducklike Anatidae with a short tail and normal bill.

PDF One hundred bird species, including honeyguides, icterids, estrildid finches and Black-headed Duck, are obligate parasites, though the most famous are the cuckoos.

The Black-headed Duck (Heteronetta atricapilla) is a South American duck allied to the stiff-tailed ducks in the subfamily Oxyurinae of the family Anatidae.

The remainder include the African whydahs and indigo birds, the cowbirds of North and South America, the honeyguides and even a duck - the black-headed duck of South America.

The Black-headed Duck is of interest as an obligate brood parasite because the females never nest and lay their eggs in the nests of other birds instead, earning it the nickname Cuckoo Duck.

Interspecific brood-parasites include the Old World cuckoos in Eurasia and Australia, American Coots, Cowbirds and Black-headed Ducks in the Americas, and indigobirds, whydahs, and the honeyguides in Africa.

The Black-headed Duck has a brood parasite relationship with the Brown-hooded Gull in which a female will lay an egg in the nest of a Brown-hooded Gull with the intent of having the host gull incubate the egg instead of herself.

The Black-headed Duck (Heteronetta atricapilla) is a South American duck allied to the stiff-tailed ducks in the subfamily Oxyurinae of the family Anatidae.
