Black hornbill

The species has a selectiveness towards the environment and resources when it comes to reproduction. It is a lowland specialist. This organism will only start breeding and nesting when there is a large supply of fruits available, and in trees of larger size. When there are limited resources available, and may curtail nesting for years when there is a low availability of fruits(4). It is the major seed disperser for Durio graveolens, a species of durian. The connection is strong enough to reflect in some of the common names for the fruit: The Kenyah and Dayak peoples call it durian anggang (lit. 'hornbill durian'), and in Malay it is called durian burong/durian burung (lit. 'durian bird'). It also has a role in seed disbursement for Vitex pinnata.

It is known to fly for hours at a time.

It is threatened by hunting and habitat loss.
