Hornbills (Bucerotidae) are a family of bird found in tropical and subtropical Africa, Asia and Melanesia. They are characterized by a long, down-curved bill which is frequently brightly coloured and sometimes has a casque on the upper mandible. Both the common English and the scientific name of the family refer to the shape of the bill, "buceros" being "cow horn" in Greek. Hornbills have a two-lobed kidney. They are the only birds in which the first and second neck vertebrae are fused together; this probably provides a more stable platform for carrying the bill. The family is omnivorous, feeding on fruit and small animals. They are monogamous breeders nesting in natural cavities in trees and sometimes cliffs. A number of mainly insular species of hornbill with small ranges are threatened with extinction, namely in Southeast Asia.

It is threatened by habitat destruction, as timber is harvested and the forests become increasingly fragmented.
The Mindoro hornbill is a species of hornbill in the family Bucerotidae. It is endemic to forests on Mindoro in the Philippines found in tropical moist lowland forests. As is the case with all Philippine tarictic hornbills, it was once considered a subspecies of P. panini. It is the only tarictic hornbill where both sexes are creamy-white and black. The sexes are very similar, differing primarily in the colour of the ocular ring. It is threatened by habitat loss, and is consequently considered endangered by the IUCN.
