A large forest coucal with a black throat and chest and a white belly. Western populations in the Democratic Republic of the Congo and extreme western Uganda are sometimes separated as Neumann’s Coucal based on their smaller size, but look very similar to eastern Black-throated Coucal populations. The similar Gabon Coucal, which has a rufous belly, replaces Black-throated in Central African forests. Black-throated typically gives a deep, bubbling, booming call series of up to 20 notes that fall and then rise in pitch. This call can be heard day or night.
