Big, spectacular, black-and-white hornbill. Both sexes show a pale bill, with a large casque that is larger in males and smaller in females. In flight, the wings are mostly black with a small white patch below, and there are white corners to the tail. Found from low to high elevations in 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 Black-and-white-casqued Hornbill, but has a paler bill, and much less white in the wings. Also reminiscent of Trumpeter Hornbill, but larger, with a bigger bill, and less white in the wings and on the belly.
