Berenicornis comatus is a large hornbill, reaching a length of 83–102 centimetres and a weight of 1.3–1.5 kilograms. Females are smaller than males. The plumage is black and white. The head, neck, breast and tail are white, while the remaining plumage is black.

It has a white crown feathers erected in a crest (hence the common name). Between the eye and the bill and on the throat there is bare dark blue skin. The bill is mainly black, with a yellowish base.

Diet
These birds are territorial and feed on various fruits, lizards, arthropods and larvae.

Behavior
The female lays two white eggs in a tree hole, then seals herself in by blocking the entrance to the nest with droppings, debris and mud. The male, and other adults and young forming a cooperative group, feed the breeding female and the chicks through a narrow hole. The female breaks the "wall" and leaves the nest when the chicks are able to fly.
