A local assistant puts a large bunch of bananas on the elevated wooden platform in the jungle, a ten minute walk away from the camp. He also leaves a bucket of milk and then walks away. Then the animals come. One orangutan appears high in a tree and slowly lowers itself down towards the platform, watching the surroundings as it descends. There’s a rustling sound on the ground behind me and I turn around to see another orangutan lumbering towards the bananas, right through a group of humans. More follow from all directions until there are about half a dozen.
