Black-and-white-casqued Hornbill Bycanistes subcylindricus

Big, spectacular, black-and-white hornbill. The males have a large black-and-white bill, and females a much smaller all-dark one. In flight, shows a broad white patch at the back of the wing and a black tail with white sides. Found in thick forest and adjacent areas of lush woodland and cultivation. Usually in pairs or small groups. The loud calls are honking and yapping notes that are often given in a quick series. Similar to White-thighed and Brown-cheeked Hornbills, but has a black center to the tail, and the wingtips are black. Also has a darker bill and casque than those species.
