Cálao Silbador Occidental Bycanistes fistulator

A medium-sized forest hornbill frequently seen flying overhead or crossing road cuts. Distinctive in its stark pied appearance, with black head, back, forewings, and central tail feathers. In flight, has very distinctive bicolored wings. Similar to African Pied Hornbill, but Piping Hornbill has broad white flight feathers, and its smaller bill and neck give it a stouter appearance. Calls include a rapid series of cackling notes, “huhuhuhuhu,” and higher-pitched piping whistles.
