[3] Berenicornis comatus is a large hornbill, reaching a length of 83–102 cm (33–40 in) and a weight of 1.3–1.5 kg (2.9–3.3 lb).

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.

[4] The forest habitat that this bird depends on has been heavily declining in recent years.

Due to this, the white-crowned hornbill was uplisted from near threatened to endangered on the IUCN Red List in 2018.
