Nature - Season 33 Episode 7 -

To truly understand the complexity of a wild orangutan society and the skills the orangutans have learned from their mothers in the wild, Ecologist Chris Morgan travels to a remote patch of forest also in Northern Sumatra, a peat swamp forest known as Suaq Balimbing. Working with a team of experienced researchers, he becomes completely immersed in this unique social band of wild orangs who use tools, share food, forage together, and create their own distinct culture.
