A nest parasite that lays its eggs in the nests of Black-cheeked and Black-faced Waxbills. As with other whydahs, breeding males are distinctive, whereas non-breeding males and females are drab and inconspicuous. Breeding males are glossy blue-black with elongated central tail feathers. Non-breeding males and females have a brownish back, a heavily striped face, and a whitish bill and legs. Generally uncommon in rather dry savanna and woodland. Non-breeding male and female can be cautiously separated from other whydahs and indigobirds by their pale bill and legs. Not very vocal, but does imitate the waxbills that it parasitizes.
