The common ostrich (Struthio camelus), or simply ostrich, is a species of flightless bird native to certain large areas of Africa and is the largest living bird species.
The common ostrich is the largest living species of bird and largest living dinosaur. It lays the largest eggs of any living bird.
The common ostrich's diet consists mainly of plant matter, though it also eats invertebrates and small reptiles. It lives in nomadic groups of 5 to 50 birds. When threatened, the ostrich will either hide itself by lying flat against the ground or run away.
They mainly feed on seeds, shrubs, grass, fruit, and flowers; occasionally they also eat insects such as locusts, small reptiles such as lizards, and occasionally animal remains left by carnivorous predators.
Lacking teeth, they swallow pebbles that act as gastroliths to grind food in the gizzard. When eating, they will fill their gullet with food, which is in turn passed down their esophagus in the form of a ball called a bolus.
