What is the writhed hornbill?

Quoted from WikipediaCC BY-SA 4.0

The writhed hornbill (Rhabdotorrhinus leucocephalus), also known as the Mindanao wrinkled hornbill, is a species of hornbill in the family Bucerotidae.

It is endemic to primarily lowland forests on the Philippine islands of Mindanao, Dinagat and Camiguin Sur. It formerly included the Walden's hornbill as a subspecies, but unlike that species, both sexes of the writhed hornbill have orange-red throat and peri-ocular skin. The writhed hornbill is threatened by habitat loss and hunting.
