Overview

The rufous hornbill (Buceros hydrocorax), also known as the Philippine hornbill and locally as kalaw (pronounced KAH-lau), is a large species of hornbill endemic to the Philippines (the largest hornbill in the country). It is called the "clock-of-the-mountains" by locals, because of its loud booming call which typically occurs every hour. Rufous hornbills inhabit moist tropical lowland forest areas, and are now regarded as a threatened species. Reasons for decline include habitat destruction, hunting and poaching for the illegal pet trade.
