Overview
Walden's hornbill (Rhabdotorrhinus waldeni), locally called dulungan or talarak, 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 (both throat and ocular skin are deep orange or red in both sexes of the writhed hornbill). Its binomial name commemorates the Scottish ornithologist Viscount Walden.
It is considered one of the Western Visayas Big 5, which includes the Negros bleeding-heart pigeon, Visayan spotted deer, Visayan hornbill and the Visayan warty pig.
