セグロコサイチョウ Tockus deckeni

A medium-sized black-and-white hornbill. Males have a mostly red bill with a yellow or white tip; females have an all-black bill. Both sexes show a mostly black wing. Generally common in dry savanna, usually in pairs or small groups. Similar to Jackson’s and Northern Red-billed Hornbills, but separated from the former by the unspotted black wing and from the latter by the yellow-tipped (male) or all-black (female) bill. The call is a series of raspy clucks, often given as a duet by a pair.
