Cameroon Indigobird Vidua camerunensis

A nest parasite that lays its eggs in the nests of African and Black-bellied Firefinches and Brown and Dybowski's Twinspots. Breeding males are glossy black with blue iridescence and a pale brownish panel in the wings. Females and non-breeding males are streaky and brown on the back and pale below, with a bold facial pattern. The bill is whitish and the legs very pale purplish. Found locally in lush woodland, savanna, and cultivated areas. Given current knowledge, can only be confidently identified by mimicked vocalizations. Each male parasitizes only one of the four host species and imitates its vocalizations, often mixing them into a scratchy jumble of high-pitched notes.
