It is also either Extinct, Endangered, Rare, or Vulnerable in Uganda. Its status in the wild is currently listed as unknown because of inadequate information in Benin, Gabon, Ghana, Guinea, and Togo Distribution Overview West and Central Africa, from Sierra Leone to the Congo region and Angola. It is a rain forest species, though it may be found in transitional forests within its range.
