Huge cuckoo that is black above and white below. Immature has white barring across its upperparts. Looks raptor-like in powerful, swooping flight. Uncommon bird of rainforest, gallery forest, and moist woodland, especially miombo. Call is a loud, repeated “wheet-it”, often given in a high display flight. Adult is separated from Great Spotted, Levaillant’s, and Pied cuckoos by its lack of a crest or white in the wing. Immature is similar to Great Spotted Cuckoo, but has black-and-white speckles on the head, and lacks a crest.
