Great Hornbills rule the roost
The Khao Yai National Park, a UNESCO World Heritage Site, is Thailand's oldest and best-known national park. It is an ecological wonderland and boasts some 390 bird species. I am told it is larger than Singapore.
As for the bird life there, the king of them all for me is the Great Hornbill (Buceros bicornis)
