The bushes shook violently and the female orang utan froze. Her baby clutched her tightly before the two quickly disappeared into the Borneo undergrowth. As the bushes parted, a broad-shouldered male orang utan strutted to the feeding platform. Dominating the fruit on offer, the male great ape dared the other orang utan in the trees to challenge him for the food.
The endangered orang utan is a solitary animal and it is rare to sight these great apes in groups, but this is Camp Leakey in the Tanjung Puting National Park in Indonesia and home to around 6,000 rescued orang utans. The park in Borneo's central Kalimantan has been protecting great apes for 38 years, but its success is now a problem as the reserve does not have sufficient space and resources to sustain any more apes.
