Ground hornbill
Large, ground-dwelling, carnivorous hornbills of African savannas.
Ground hornbills are large, terrestrial birds belonging to the genus *Bucorvus* within the hornbill family, Bucerotidae. They are endemic to the open savanna regions of sub-Saharan Africa. Two species are recognized: the Abyssinian ground hornbill, whose range extends in a belt from Senegal eastward to Ethiopia, and the southern ground hornbill, found in southern and East Africa. These birds are notably large, with adults reaching approximately one meter in height. Unlike most other hornbills, which are arboreal, ground hornbills are primarily ground-dwelling. Their diet is carnivorous, consisting of insects, snakes, other birds, amphibians, and even tortoises. The genus *Bucorvus* was first introduced in 1830 by the French naturalist René Lesson, originally as a subgenus, to accommodate a single species, *Buceros abyssinicus* (the Abyssinian ground hornbill), which serves as the type species. The generic name is a portmanteau combining *Buceros*, the genus established by Carl Linnaeus in 1758 for Asian hornbills, with *corvus*, the Latin word for raven. A molecular phylogenetic study from 2013 determined that the genus *Bucorvus* is sister to all other hornbills, with the lineage estimated to have diverged in the early Miocene, around 22 million years ago. Due to their distinct characteristics, ground hornbills have sometimes been placed in their own separate family, Bucorvidae.

Lore & Background
Ground hornbills are large birds, with adults standing approximately one meter tall. They are endemic to the open savanna regions of sub-Saharan Africa. The Abyssinian ground hornbill is found in a belt stretching from Senegal eastward to Ethiopia, while the southern ground hornbill inhabits southern and East Africa. Unlike other hornbills, both species are primarily ground-dwelling. They are carnivorous, feeding on a diet that includes insects, snakes, other birds, amphibians, and even tortoises. The genus *Bucorvus* was introduced in 1830 by the French naturalist René Lesson, originally as a subgenus, to accommodate a single species, the Abyssinian ground hornbill. The generic name is a portmanteau of *Buceros* (the genus for Asian hornbills) and *corvus*, the Latin word for raven. A 2013 molecular phylogenetic study revealed that the genus *Bucorvus* is sister to all other hornbills, and the lineage is estimated to have diverged from them in the early Miocene, approximately 22 million years ago. Ground hornbills have sometimes been placed in their own separate family, Bucorvidae. The genus contains two species.
Reader's Guide
Ground hornbills are significant as a distinct lineage within the hornbill family, representing an early divergence estimated at 22 million years ago. Their ground-dwelling and carnivorous habits set them apart from all other hornbills, which are typically arboreal and omnivorous. The two species—the Abyssinian ground hornbill, ranging from Senegal to Ethiopia, and the southern ground hornbill in southern and East Africa—are endemic to open savanna regions. The taxonomic placement of the genus has been disputed, with some authorities placing Bucorvus in a separate family, Bucorvidae, reflecting its unique evolutionary history. Their large size (around a metre tall) and diet including snakes, other birds, amphibians, and tortoises underscore their role as apex avian predators in their ecosystems.

Frequently Asked Questions
What is a ground hornbill?
Ground hornbills are two large, meat-eating hornbill species in the genus Bucorvus, found exclusively in the open grasslands of sub-Saharan Africa. They stand roughly a metre tall and are among the most visually striking residents of the African savanna.
How do ground hornbills differ from other hornbills?
Where most hornbills are tree-dwelling fruit eaters, ground hornbills live on the ground and actively hunt animal prey. Their carnivorous, terrestrial habits are so unusual that some taxonomists have argued they deserve a separate family, Bucorvidae.
What does a ground hornbill eat?
Their diet is almost entirely animal-based, stretching from insects and amphibians up to snakes, small birds, and even tortoises. This makes them true predators rather than the frugivores most other hornbill species are.
Where can you find ground hornbills in the wild?
They are restricted to open savanna habitats across sub-Saharan Africa. The Abyssinian ground hornbill ranges from Senegal eastward to Ethiopia, while the southern ground hornbill occupies grasslands in southern and East Africa.
How many species of ground hornbill are there?
There are exactly two recognized species: the Abyssinian ground hornbill and the southern ground hornbill. Both sit within the genus Bucorvus of the hornbill family Bucerotidae.
