The ground hornbills are the only ground dwellers among hornbills. The large bill characteristic of the Bucerotidae family may be why hornbills are the only birds with the first two neck vertebrae (axis and atlas) fused together. Hornbills are notable for their long eyelashes and rather stubby legs and toes, with broad soles and the bases of the three front toes partly fused.
- The African Ground hornbill’s throat skin is inflatable, and sometimes inflates when it makes its guttural call.
- Territory size for the African ground hornbill is up to 39 square miles.
