Ostrich
These animals are more dangerous than you may think. The Ostrich is one or two species of large flightless birds native to Africa, the only living member(s) of the genus Struthio. Some analyses indicate that the Somali Ostrich may be better considered a full species apart from the Common Ostrich, but most taxonomists consider it to be a subspecies.
Ostriches share the order Struthioniformes with the kiwis, emus, and other ratites. It is distinctive in its appearance, with a long neck and legs and the ability to run at maximum speeds of about 70 kilometres per hour (43 mph)[3], the top land speed of any bird.[4][5] 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 did lay larger eggs) .

The ostrich or common ostrich is either one or two species of large flightless birds native to Africa, the only living member of the genus ''Struthio'', which is in the ratite family.
