The ground hornbills (Bucorvidae) are a family of the order Bucerotiformes, with a single genus Bucorvus and two extant species. The family is endemic to sub-Saharan Africa : the Abyssinian ground hornbill occurs in a belt from Senegal east to Ethiopia , and the southern ground hornbill occurs in southern and East Africa .
Southern ground hornbills can be found from northern Namibia and Angola to northern South Africa and southern Zimbabwe to Burundi and Kenya. They require a savanna habitat with large trees for nesting and dense but short grass for foraging. [15] The southern ground hornbill is a vulnerable species, mainly confined to national reserves and ...

The smallest species is the black dwarf hornbill (Tockus hartlaubi), at 99.1 g (3.50 oz) and 32 cm (1 ft 1 in) in length. [ 3 ] [ 4 ] The largest and most massive species appears to be the southern ground hornbill which has an average weight of 3.77 kg (8.3 lb), and can weigh up to 6.3 kg (14 lb) and span about 180 cm (5 ft 11 in) across the wings.
The Abyssinian ground hornbill was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in 1780 in his Histoire Naturelle des Oiseaux.

Recent genetic data shows that Bycanistes is the sister taxon to ground hornbills, this clade having diverged from the rest of the hornbill lineage early on. [2] Bycanistes is thought to represent an early African lineage, while the remaining Bucerotiformes evolved in Asia.
