The white-crowned hornbill (Berenicornis comatus), also known as the long-crested hornbill or white-crested hornbill (leading to easy confusion with the African white-crested hornbill), is a species of hornbill.
This species is found in the Malay Peninsula, Sumatra and Borneo.
This bird inhabits rainforests at low and medium altitudes, usually at an elevation below 900 meters. It may also be found on fruit, oil-palm and rubber plantations. It is threatened by habitat destruction.
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.
