Chacma baboons are known to eat fruits, including Kigelia pinnata fruit and figs from both Ficus sycomorus and Ficus burki. They also eat leaves, including the crowns of Cypress trees, tree gums, insects, eggs, seeds, including the green seeds of Acacia nigrens, flowers, water lilies (Nymphaea caerulea), grass, rhizomes, corms, roots, tubers, and small vertebrates.
One feeding adaptation thought to be shared by all baboons is the ability to subsist on a relatively low quality diet. Baboons can subsist on grasses for extended periods of time. This allows them to exploit dry terrestrial habitats, like deserts, semideserts, steppes, and grasslands.
