In the frame of this project, we aim to compare caloric intakes and nutrient compositions of the diets of different age-sex classes. For this, we collect and analyze the fruits and other food items in the diet of the orangutans at Suaq. We further want to investigate how these factors develop in immatures as a function of their age and skill levels. Furthermore, we want to find out if mothers adapt their diets to facilitate the learning process of their offspring.
