Imprinting and the origin of parasite-host species associations in brood-parasitic indigobirds, Vidua chalybeata
Article Abstract:
Female brood-parasitic village indigobirds, Vidua chalybeata, are attracted to songs that mimic their own foster species more than to songs of other species, according to research on indigobirds bred in captivity and foster-reared by the red-billed firefinch, Lagonosticta senegala, their usual host species, or by the Bengalese finch, Lonchura striata. It was found that the birds sought out and layed in the nests of the species that reared them. They also imprinted on songs of their foster species and are sexually attracted to songs of male indigobirds that mimic the same foster species.

Parental care in estrildid finches: experimental tests of a model of Vidua brood parasitism
Article Abstract:
Research into whether three species of African estrildid finches give foster parental care only to young with normal conspecific appearance and behaviour or to other young in their nests as well is presented. It was found that all three finches raised the young of other estrildid finch species.

Song learning in brood-parasitic indigobirds Vidua chalybeata: song mimicry of the host species
Article Abstract:
Song learning among parasitic indigobirds was investigated using birds reared by conventional and novel hosts, red-billed fire finch and Bengalese finch, respectively. Male indigobirds learned the songs of their foster fathers only if they stayed with the foster father long after independence or about 45 days after fledging. Males separated at the normal age of independence copied the songs of other birds.
