At the heart of South East Asia, in Borneo's steaming jungles, evolutionary forces churn out the beautiful and bizarre. Taking form as condensed vapor in distant mountains, the waters of the Kinabatangan River have passed over rapids, through hilly country, and into floodplains. But this is an El Nino year, which means the rains are unusually late. From the unusual nesting practices of Hornbills, to the jungle skills of Orangutans, life rises to meet nature's challenges. On fickle floodplains the river's nourishment fuels herds of elephants, cave dwellers in their millions and miniature bears of the canopy. It's another day for life on Borneo's Secret Kingdom.
