The second of a six-part series of zoological exploration.
Introduced by Jeffery Boswall

The Khao Yai National Park is reputedly the best in all south-east Asia. The expedition is guided through the park by Thai conservationist Supradit Kanwanich, who shows off the rain forest plants and animals.
One of these, the great hornbill, is looked at in detail: its nesting, its plumage and moult and its enormous ornamental bill. From a specially built tower we watch as a fig tree with ripening fruit attracts a wide variety of feasting birds and mammals: barbets and bulbuls, gibbons and macaques, bluebirds, and, of course, our splendid great hornbill.
