Northern Rufous Hornbill

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.
It is illegal to hunt, capture or possess rufous hornbills under Philippine Law RA 9147.
