Writhed Hornbill

Rhabdotorrhinus leucocephalus (Vieillot, LJP 1816)

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. Source: Wikipedia
