Ostrich

The ostrich or common ostrich (Struthio camelus) is either one or two species of large flightless birds native to Africa, the only living member(s) of the genus Struthio, which is in the ratite family. Some analyses indicate that the Somali ostrich may be better considered a full species separate from the Common Ostrich, but most taxonomists consider it to be a subspecies. The ostrich shares the order Struthioniformes with the kiwis, emus, rheas and cassowaries. However, phylogenetic studies have shown that it is the basal extant member of Palaeognathae and is thus equally closely related to flighted tinamous.[3][4] It is distinctive in its appearance, with a long neck and legs, and can run at up to about 70 km/h (20 m/s; 40 mph),[5] the fastest
