trumpetarnäshornsfågel Bycanistes bucinator

A large, mostly black-and-white hornbill that occurs in thickets, dense woodland, and riverine and coastal forest. It can be surprisingly inconspicuous while eating large fruit in forest trees, but in flight it has noisy wingbeats and a far-carrying baby-like wailing “whaaaaaa waa waa” call. In flight note narrow white hind edges to the mostly dark wings; the similar Black-and-white-casqued Hornbill has a very broad white hind edge, and the Silvery-cheeked Hornbill has no white hind edge.
