Orangutans are primarily fruit eaters.
Picture from San Diego Zoo
Mornings are usually spent forging through the forest for fruit. If none presents itself, the orangutan will then feast on leaves, flowers, bark, termites and other insects. While female and young orangutans are social while eating, the male orangutan tends to eat in a more solitary area.
Orangutans spend most of their lives in trees and travel by swinging from branch to branch with their long arms. They usually build a new nest every night, but may occasionally reuse one. The apes also use leafy branches to shelter themselves from rain and sun, and sometimes they drape large leaves over themselves like a poncho! - See more at: http://animals.sandiegozoo.org/animals/orangutan#sthash.dIdlQZ7N.dpuf
