African pied hornbill : ウィキペディア英語版 | African pied hornbill
The African pied hornbill, ''Tockus fasciatus'', is a bird of the hornbill family, a family of tropical near-passerine birds found in the Old World. The African pied hornbill is a common resident breeder in much of equatorial Africa, from The Gambia to western Uganda and northern Angola. This is a bird of mainly forest habitats. The female lays up to four white eggs in a tree hole, which is blocked off during incubation with a cement made of mud, droppings and fruit pulp. There is only one narrow aperture, just big enough for the male to transfer food to the mother and the chicks. ==Morphology==
This is a large bird, in length. It has mainly black plumage, with white belly and tail tip. The long, curved black and yellow bill has a medium-sized casque. The sexes are similar, but the female has a smaller casque. Immature birds are duller, have a smaller bill, and no casque. The flight is undulating.
