Writhe-billed Hornbill
Rhabdotorrhinus waldeni
Walden's hornbill locally called dulungan, also known as the Visayan wrinkled hornbill, rufous-headed hornbill or writhe-billed hornbill, is an endangered species of hornbill living in the rainforests on the islands of Negros and Panay in the Philippines. It is closely related to the writhed hornbill, but can be recognized by the yellow throat and ocular skin in the male, and the blue throat and ocular skin in the female. Its binomial name commemorates the Scottish ornithologist Viscount Walden.
