Identification
A nest parasite that lays its eggs in the nests of Zebra Waxbills. Breeding males are glossy black with green or 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. A scarce and poorly known species. Found in wetlands, moist grasslands, and cultivation. Given current knowledge, can only be confidently identified by vocalizations. Imitates the “svet” calls of its host, Zebra Waxbill, and often mixes them into a scratchy jumble of high-pitched notes.
