The ostrich is the largest bird in the world, but it cannot fly. Its legs are so strong and long that it can travel faster by running. Ostriches use their wings to help them to gather speed when they start to run. They also use them as brakes when they are turning and stopping.

Ostriches have been known to run at a rate of 96 kms an hour. This is faster than horses can run and as fast as most people drive cars.

These huge birds stand as tall as a horse and sometimes weigh as much as 135 kgs. In North Africa, they are often seen with other larger animals.The zebra, which is also a fast runner, seems to be one of their favorite companions.

Each ostrich egg weighs as much as two dozen chicken eggs, or one and a half kg. Ostrich eggs are delicious and are often used for food by people in Africa. The shells also are made into cups and ornaments.

Based on the passage, what is another animal that an ostrich may be found near?
