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.
