Ostriches are flightless birds found only in open country in Africa. The largest living birds, adult males may be 2.75 meters (about 9 feet) tall—almost half of that height being in the neck—and weigh more than 150 kilograms (330 pounds). Ostriches are seen individually, in pairs, in small flocks, or in large aggregations, depending on the season. The ostrich relies on its strong legs—uniquely two-toed, with the main toe developed almost as a hoof—to escape its enemies, chiefly humans and the larger carnivores. A frightened ostrich can achieve a speed of 72.5 kilometers (45 miles) per hour.

If cornered, it can deliver dangerous kicks capable of killing lions and other large predators. Deaths from kicks and slashes are rare, with most attacks resulting from humans provoking the birds.
