| [Note Guidelines] Photographer's Note |
I was fascinated to see this large bird, with its large eyes slowly walking across the savannah.
Unlike all other hornbills, ground-hornbills do not seal the female inside a nest cavity, they walk instead of hop, they lack a carotid artery (unique among all birds), and they have 15 instead of 14 neck vertebrae. Other hornbills prefer to rest in trees, ground hornbills prefer the ground.
They were evident as a mid-Miocene fossil from Morocco some 15 million years ago.
