Writhed hornbill
The writhed hornbill, also known as the Mindanao wrinkled hornbill, is a species of hornbill in the family Bucerotidae.
It is endemic to humid 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.
