Rufous Hornbill

The rufous hornbill, also known as the Philippine hornbill and locally as kalaw, is a large species of hornbill endemic to the Philippines. 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.
