The Ostrich is the largest living species of bird and lays the largest egg of any living bird (extinct elephant birds of Madagascar and the giant moa of New Zealand laid larger eggs). It is distinctive in its appearance, with a long neck and legs and the ability to run at maximum speeds of about 70 km/h (45 mph), the top land speed of any bird. The Ostrich is farmed around the world, particularly for its feathers, which are decorative and are also used as feather dusters. Its skin is used for leather products and its meat marketed commercially.
