The black coucal (Centropus grillii) is a species of cuckoo in the Cuculidae family. It is found in Angola, Benin, Botswana, Burkina Faso, Burundi, Cameroon, Central African Republic, Chad, Republic of the Congo, Democratic Republic of the Congo, Ivory Coast, Ethiopia, Gabon, Gambia, Ghana, Guinea, Guinea-Bissau, Kenya, Liberia, Malawi, Mali, Mozambique, Namibia, Niger, Nigeria, Rwanda, Senegal, Sierra Leone, South Africa, Sudan, Swaziland, Tanzania, Togo, Uganda, Zambia, and Zimbabwe.

The species has the role of sexes reversed with the males tending the nest while females are polyandrous and maintain territories. Studies on the hormonal system show that progesterone is responsible for controlling the aggressiveness of females.[2]
