Wikipedia Abstract

The black-and-white-casqued hornbill (Bycanistes subcylindricus) also known as the grey-cheeked hornbill, is a large—approximately 70 cm (28 in) long—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. Widespread and still locally common, the black-and-white-casqued hornbill is assessed as least concern on the IUCN Red List of Threatened Species.
