Ostrich

Ostriches are large flightless birds of the genus Struthio in the order Struthioniformes, part of the infra-class Palaeognathae, a diverse group of flightless birds also known as ratites that include the emus, rheas, and kiwis. The common ostrich and the Somali ostrich are the only two species of ostrich that exist today.

They are indigenous to Africa and are the only living land animals to lay the largest eggs. They can run at a speed of 70 km/h (43.5 mph), making them the quickest birds on land. Today, ostriches are only found natively in the wild in Africa, where they occur in a range of open arid and semi-arid habitats such as savannas and the Sahel, both north and south of the equatorial forest zone. The fact that ostriches are the heaviest living birds is noteworthy.
