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. The black-and-white-casqued hornbill is found in wooded habitats in central and western Africa, ranging from western Kenya to Côte d'Ivoire with an isolated population in north Angola. 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.[1] GalleryReferences1. ^1 {{IUCN|id=22682577 |title=Bycanistes subcylindricus |assessor=BirdLife International |assessor-link=BirdLife International |version=2013.2 |year=2012 |accessdate=26 November 2013}} External links
