The largest living bird is the ostrich which can be as big as 8 feet tall and 330 pounds. The ostrich relies on its speed, size and strong kick rather than flight for safety. An ostrich can kill a person with one kick and can run up to 40 miles per hour.
Ostriches live in flocks in dry parts of Africa . Flocks can have as many as 600 birds in them.
Ostriches are vegetarian and spend much of their time searching out water.
