Bycanistes
''Bycanistes'' is a genus of medium to large, primarily frugivorous hornbills (family Bucerotidae) found in the forests and woodlands of Sub-Saharan Africa. They have often been included in the genus ''Ceratogymna'', but today most authorities consider them separate. All species in this genus have black and white plumage. The plumage of the sexes is similar, but the casque of the male is larger than that of the female. 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.Woodruff, D. S. & Srikwan, S. 2011. Molecular genetics and the conservation of hornbills in fragmented landscapes. In Poonswad, P. (ed) The Asian Hornbills: Ecology and Conservation. National Center for Genetic Engineering and Biotechnology, Bangkok, pp. 257-264. ''Bycanistes'' is thought to represent an early African lineage, while the remaining Bucerotiformes Bucerotiformes is an order of birds that ...

Black-and-white-casqued Hornbill
The black-and-white-casqued hornbill (''Bycanistes subcylindricus'') also known as the grey-cheeked hornbill, is a large black and white hornbill. It has an oversized blackish bill with a large casque on top. The female is slightly smaller than the male and has a significantly smaller casque. It is a monogamous species, and pairs nest in suitable tree cavities. The female usually lays up to two eggs. The diet consists mainly of figs, fruits, insects and small animals found in the trees. Widespread and still locally common, the black-and-white-casqued hornbill is assessed as least concern on the IUCN Red List of Threatened Species. Taxonomy ''Bycanistes subcylindricus'' is part of the ''Bycanistes'' genus of sub-Saharian hornbills which currently include a total of six known species that all share a black and white plummage and are mostly frugivores. This genus has recently been related to the '' Bucorvus'' genus, known as Ground Hornbills. Most of the species in that genus ha ...

Bucerotidae
Hornbills (Bucerotidae) are a family of bird found in tropical and subtropical Africa, Asia and Melanesia. They are characterized by a long, down-curved bill which is frequently brightly coloured and sometimes has a casque on the upper mandible. Both the common English and the scientific name of the family refer to the shape of the bill, "buceros" being "cow horn" in Greek. Hornbills have a two-lobed kidney. They are the only birds in which the first and second neck vertebrae (the atlas and axis respectively) are fused together; this probably provides a more stable platform for carrying the bill. The family is omnivorous, feeding on fruit and small animals. They are monogamous breeders nesting in natural cavities in trees and sometimes cliffs. A number of mainly insular species of hornbill with small ranges are threatened with extinction, namely in Southeast Asia. In the Neotropical realm, toucans occupy the hornbills' ecological niche, an example of convergent evolution. Des ...

Bucerotiformes
Bucerotiformes is an order of birds that contains the hornbills, ground hornbills, hoopoes and wood hoopoes. These birds were previously classified as members of Coraciiformes. The clade is distributed in Africa, Asia, Europe and Melanesia. Systematics Recent genetic data show that ground hornbills and ''Bycanistes'' form a clade outside the rest of the hornbill lineage. They are thought to represent an early African lineage, while the rest of Bucerotiformes evolved in Asia. The hoopoe subspecies Saint Helena hoopoe and the Madagascar subspecies are sometimes elevated to a full species. The two wood hoopoe genera, ''Phoeniculus'' and '' Rhinopomastus'', appear to have diverged about 10 million years ago, so some systematists treat them as separate subfamilies or even separate families. Extinct Messelirrisoridae and Laurillardiidae families were both considered to be stem groups of a previously categorized Upupiformes order prior to it being subcategorized into Bucerotifo ...

Silvery-cheeked Hornbill
The silvery-cheeked hornbill (''Bycanistes brevis'') is a large species of hornbill found in Africa. Silvery-cheeked hornbills are residents of the tall evergreen forests of East Africa from Ethiopia to South Africa. In Zimbabwe it is threatened by habitat destruction and its presence in South Africa is marginal, but it remains locally fairly common, especially in the northern and central parts of its range. Description It measures in length, and has a very large cream-colored casque on the beak. The head is silver-grey and the rest of the plumage is iridescent black, except for the white rump, lower back, thighs, vent and tip of the outer tail-feathers. The sexes are similar except the female has a smaller casque and reddish skin around the eyes. Diet It is omnivorous, feeding on fruits, insects, small birds, rodents, small reptiles and centipede Centipedes (from New Latin , "hundred", and Latin , " foot") are predatory arthropods belonging to the class Chilopoda (An ...

Brown-cheeked Hornbill
The brown-cheeked hornbill (''Bycanistes cylindricus'') is a species of hornbill in the family Bucerotidae. It is found in Ivory Coast, Ghana, Guinea, Liberia, Sierra Leone, and Togo. Its natural habitats are tropical and subtropical moist broadleaf forests, plantations, and secondary growth forests. It is threatened by habitat destruction, as timber is harvested and the forests become increasingly fragmented. Description The brown-cheeked hornbill is a large bird, measuring in length. The male has a large yellow, down-curving beak topped by a casque, a hollow structure attached to the upper mandible. The head, upper parts and underparts are black apart from the reddish-brown cheeks, and the white rump, belly and tail. The female is smaller but otherwise similar to the male apart from having a black beak and casque. Its call is a descending series of coarse croaks "rrah...rrah...rrah...rrah" or "rack kack kak-kak". Distribution and habitat The brown-cheeked hornbill is native ...

Trumpeter Hornbill
The trumpeter hornbill (''Bycanistes bucinator'') is a medium-sized hornbill, with length between , characterized by a large grey casque on the bill, smaller in females. The eyes are brown or red, with pink surrounding skin. Body mass is between .''CRC Handbook of Avian Body Masses'' by John B. Dunning Jr. (Editor). CRC Press (1992), . It is similar to silvery-cheeked hornbill. Distinguishing features include an all-black back, white belly and white underwing coverts (in flight, wings present white tips), and red facial skin. The trumpeter hornbill is a gregarious bird, usually living in groups of two to five individuals, although sometimes as many as fifty. This hornbill is a locally common resident of the tropical evergreen forests of Burundi, Mozambique, Botswana, Congo, Kenya, the Caprivi strip of Namibia and eastern South Africa, where it feeds on fruits and large insects. Like other hornbills, the females incubate four to five white eggs while sealed in the nest compartme ...

Ceratogymna
''Ceratogymna'' is a genus of large, primarily frugivorous hornbills (family Bucerotidae) found in the humid forests of Central and West Africa. They are sexually dimorphic: males are all black, while females have brown heads and a smaller casque.Kemp, A. C. (2001). Family Bucerotidae (Hornbills). Pp. 436-523 in: del Hoyo, J., Elliott, A., & Sargatal, J. eds. (2001). ''Handbook of the Birds of the World.'' Vol. 6. Mousebirds to Hornbills. Lynx Edicions, Barcelona. Unlike the members of the genus ''Bycanistes'', the two species in the genus ''Ceratogymna'' have extensive, primarily blue, bare facial skin and dewlap, and the only white in their plumage is in the tail (although the yellow-casqued wattled hornbill has slight whitish speckling on the neck).
