The Ostrich is a of large flightless birds native to Africa, the only living member of the genus Struthio.
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 60.6 mph, the top land speed of any bird. The Ostrich is the largest living species of bird and lays the largest egg of any living bird .
The diet of Ostriches mainly consists of plant matter, though it also eats invertebrates. It lives in nomadic groups which contain between five and fifty birds. When threatened, the Ostrich will either hide itself by lying flat against the ground, or will run away. If cornered, it can attack with a kick from its powerful legs. Mating patterns differ by geographical region, but territorial males fight for a harem of two to seven females. These fights usually last just minutes, but they can easily cause death through slamming their heads into opponents.
