As a sacred bird, traditional healers believe that killing a Ground Hornbill is a bad omen and seeing a live Ground Hornbill is a symbol of prosperity and good luck. Why then are Ground Hornbills under severe threat with the only stronghold for the species being within formal conservation areas? The Ground Hornbill is distributed as far north in Africa as Rwanda, Burundi and Kenya, down the east coast as far south as the Eastern Cape in South Africa
