Ostrich

The ostrich Struthio camelus is a large flightless bird native to Africa (and formerly the Middle East). It is the only living species of its family, Struthionidae, and its genus, Struthio. Ostriches share the order Struthioniformes with the Emu, kiwis, and other ratites. It is distinctive in its appearance, with a long neck and legs and the ability to run at speeds of about 74 km/h (46 mph), the top land speed of any bird. The ostrich is the largest living species of bird and lays the largest egg of any bird species.
