* Bark: They will strip the bark off trees and eat the cambium layer, which is rich in nutrients but also fibrous.
* Leaves: They will eat more leaves, even the tough, less palatable ones.
* Shoots and buds: These provide some nutrition, but they are less abundant than fruits.
* Insects: They may consume more insects, especially termites, ants, and caterpillars.
* Soil: Chimpanzees have been observed eating soil, which may help with nutrient absorption or provide essential minerals.
* Other non-preferred fruits: They will eat fruits that are overripe, bruised, or less palatable.
The specific food choices will depend on the local environment and what is available.
Importantly: Chimpanzees rely on strong social bonds to navigate food scarcity. They may travel greater distances, share food, and even engage in food-related conflict.
