Ostriches eat grass, leaves, seeds, shoots, succulents, roots, flowers with stems, fruits, etc. They also eat lizards, snakes, young birds, small mammals and some insects.

Ostrich's food is mainly plant stems and leaves. Artificial ostriches are fed with synthetic feed. When eating, ostriches always deliberately eat some sand grains, because ostriches have poor digestion ability. Eating some sand grains can help grind food and promote digestion without hurting the spleen and stomach.
