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 includes the emus, rheas, and kiwis. There are two living species of ostrich: the common ostrich, native to large areas of sub-Saharan Africa and the Somali ostrich, native to the Horn of Africa. The common ostrich was also historically native to the Arabian Peninsula, and ostriches were present across Asia as far east as Mongolia during the Late Pleistocene and possibly into the Holocene. They lay the largest eggs of any living land animal. With the ability to run at 70 km/h (43.5 mph), they are the fastest birds on land. They are farmed worldwide, particularly for their feathers as they are used as decoration and feather dusters. Their skin is also used for leather products. They are the heaviest living birds.

Common Ostrich
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. It is one of two extant species of ostriches, the only living members of the genus ''Struthio'' in the ratite order of birds. The other is the Somali ostrich (''Struthio molybdophanes''), which was recognized as a distinct species by BirdLife International in 2014 having been previously considered a distinctive subspecies of ostrich. The common ostrich belongs to the order (biology), order Struthioniformes. Struthioniformes previously contained all the ratites, such as the Kiwi (bird), kiwis, emus, Rhea (bird), rheas, and Cassowary, cassowaries. However, recent genetic analysis has found that the group is not monophyletic, as it is paraphyletic with respect to the tinamous, so the ostriches are now classified as the only members of the order. Phylogenetic studies have shown that it is the sister group to all ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
