There are 7000 (at the last count, and who knows when that was?) Orangutans round this National Park and a feeding centre, provides some bland but nutritious food for those who are struggling or just a bit lazy. Walking up there the following day there is a rumble in the undergrowth, and an orange ball of fluff tumbles onto the path between us. We later watch this 7 yr old, descend vines above our heads, down on to the feeding platform.
