The Black-and-white-casqued Hornbill, Bycanistes subcylindricus, also known as Grey-cheeked Hornbill, is a large, approximately 70 cm long, black and white hornbill. It has an over-sized blackish bill with large casque on top. The female is slightly smaller than the male.
The Black-and-white-casqued Hornbill is distributed to evergreen forests and savanna across equatorial Africa, in central and western Africa. A monogamous species, 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 common throughout its large habitat range, the Black-and-white-casqued Hornbill is evaluated as Least Concern on the IUCN Red List of Threatened Species.
