The Black-and-white-casqued Hornbill can be found in sub-Saharan Africa, where it inhabits the forests and woodlands. They prefer lowland forests, but can also be found in mountainous regions.

This bird species requires large tracts of undisturbed forest to thrive, and it is typically found in areas with a high canopy and a dense understory.

Movements and Migration

Black-and-white-casqued Hornbills are generally non-migratory birds, and they do not undertake long-distance movements or migrations. However, they may move short distances within their range in search of food or suitable nesting sites.

During the dry season when food may be scarce, they may move to areas where food is more abundant. In addition, juvenile birds may disperse from their natal areas once they reach maturity and begin breeding.

Dispersal distances can vary, with some individuals traveling long distances to establish their own territories.

Breeding and Nesting

Breeding season for the Black-and-white-casqued Hornbill varies by region, but it generally occurs between November and May. This bird species is monogamous, and pairs will stay together for several years.

Courtship behavior involves the male feeding the female and presenting her with food gifts. The nest of the Black-and-white-casqued Hornbill is typically a cavity in a tree, which is sealed off by the female using a mixture of mud, fruit pulp, and feces.

Once inside the nest, the female will lay a clutch of 1-2 eggs, which she will incubate for around 40 days. The male will provide food for the female during this time.

After hatching, both parents will feed the chicks, regurgitating food into their beaks.

Conservation Status

The Black-and-white-casqued Hornbill is currently listed as a vulnerable species by the International Union for Conservation of Nature (IUCN).

Habitat loss and fragmentation due to human activity and climate change are major threats to this bird species.

In addition, hunting for its casque and eggs is also a threat. Several conservation measures have been put in place to protect the Black-and-white-casqued Hornbill.
