While they have been observed to occasionally eat insects and small animals, their primary food source is plants. Their diet consists mainly of:
* Fruits: Their favorite food, especially ripe ones like figs.
* Leaves: They consume a wide variety of leaves, both young and mature.
* Stems: They eat the stems of plants, particularly those with high water content.
* Bark: They strip the bark off of trees, often to reach the inner bark for its nutrients.
* Roots: They dig up roots and tubers for their carbohydrates.
Their strong jaws, flat molar teeth, and digestive system are all adapted to processing plant matter, making them primarily herbivores.
