The orangutans are free in the forest. They stop by the viewing points because of the tasty food (many were also brought here for rehabilitation so they are comfortable seeing people – though the rehabilitation is largely moved elsewhere now).
The orang utan is found in the rainforests of Malaysian Borneo (Sarawak and Sabah), Indonesian Borneo (Kalimantan) and North Sumatra. It is one of the world’s largest primates, and is almost completely arboreal (tree living). The word “orang” is Malay for “person” whilst “utan” is derived from “hutan” meaning forest. Thus, orangutan literally translates as “person of the forest”.
