The ostrich is the largest of all birds. It is found in the grassland areas of Africa. It eats fruits, leaves and seeds. An ostrich has wings but cannot fly. Instead, it runs very fast. It can run at a speed of eighty kilometres an hour. Ostrich feathers are soft because they are not needed for flying. Unlike other birds, the ostrich has only two toes on each leg. Struthio is a genus of birds in the order Struthioniformes, whose members are the ostriches. It is part of the infra-class Palaeognathae, a diverse group of beautiful flightless birds also known as ratites that includes the emus, rheas, and kiwis. There are two living species of ostrich, the common ostrich and the Somali ostrich. They are large flightless birds of Africa who lay the largest eggs of any animal living on land. With the ability to run at 70 km/h (43.5 mph), they are the fastest birds on land. It is farmed worldwide, particularly for its feathers as they are used as decoration and feather dusters. Its skin is also used for leather products.
