The western red-billed hornbill (Tockus kempi) is a species of hornbill in the family Bucerotidae. It is found from Senegal and Gambia to southern Mauritania and western Mali. There are five species of red-billed hornbills generally recognized now, but all five were once considered conspecific. Some authorities still categorize the group as Tockus erythrorhynchus with the remaining four as its subspecies^[1]
