When running, ostriches primarily rely on their strong and long legs, which can take strides of up to 15 feet (4.6 meters). They have two toes, with the larger and more robust toe functioning as a hoof-like structure that provides better traction and support.
In terms of speed, ostriches can reach impressive velocities. Their average running speed is usually between 31 miles per hour (50 km/h) to 43 miles per hour (70 km/h). However, ostriches have been recorded to achieve even faster speeds of up to 50 miles per hour (80 km/h) over shorter distances.
It's worth mentioning that ostriches primarily use their exceptional speed for escaping from predators or reaching new sources of food and water. They are opportunistic omnivores and feed on various plants, insects, and small animals.
