A Day in the Life of a Foraging Ostrich: Real Wild Menus Caught on Camera
By James H. Sterling
Q1: Do ostriches eat meat regularly in the wild?
Ostriches are opportunistic feeders that consume small animals whenever available, but they are not active predators. Meat and invertebrates account for an estimated 10% to 20% of their wild diet, consisting mainly of grasshoppers, crickets, lizards, and small mice encountered while foraging for plants.
Q2: Why do ostriches swallow large rocks?
Ostriches lack teeth to chew tough plant fibers. They swallow smooth pebbles, called gastroliths, which remain in their muscular gizzard. The stones grind dense seeds, roots, and fibrous twigs into a fine paste so the gut can ferment and absorb the nutrients.
Q3: How long can an ostrich survive without drinking water?
In arid savannas and deserts, an ostrich can go for several weeks without drinking open water. They extract sufficient hydration by consuming succulent leaves, wild desert melons, morning dew, and the internal fluids of small insects.
Q4: What should you feed an ostrich in captivity?
Captive birds require a clean diet of balanced commercial ostrich pellets, chopped alfalfa hay (lucerne), leafy greens, fresh water, and free-choice granite grit. They also need calcium supplements like crushed oyster shell to prevent bone issues and egg binding.
