A wild Sumatran orangutan in Gunung Leuser National Park, in Northern Sumatra. This species is critically endangered according to the IUCN red list, due to habitat loss, as a consequence of palm oil exploitation and logging. Less than 3,500 orangutans still survive in the wild. We found this big male while hiking into the primary forest, and after initial mistrust, it became confident allowing me to take some wide-angle shots.
