Subspecies
Species has often been listed as Bucorvus cafer on grounds that original description of leadbeateri, based on a specimen now lost, is claimed to refer to a female of Northern Ground-hornbill (Bucorvus abyssinicus). However, convincing evidence now suggests that the lost specimen was a female of present species, so leadbeateri should be retained and cafer considered a junior synonym.
