The genus was used by Linnaeus and other early taxonomists to include the emu, rhea, and cassowary, until they each were placed in their own genera. [1] The Somali ostrich (Struthio molybdophanes) has recently become recognized as a separate species by most authorities, while others are still reviewing the evidence. [6] [7]
The common ostrich (Struthio camelus), or simply ostrich, is a species of flightless bird native to certain areas of Africa. It is one of two extant species of ostriches, the only living members of the genus Struthio in the ratite order of birds.
The two extant species of ostrich are the common ostrich and Somali ostrich, both in the genus Struthio, which also contains several species known from Holocene fossils such as the Asian ostrich. The common ostrich is the more widespread of the two living species, and is the largest living bird species.

The North African ostrich, [1] red-necked ostrich, or Barbary ostrich (Struthio camelus camelus) is the nominate subspecies of the common ostrich from West and North Africa. It has the largest average size among the subspecies of ostriches, making it the largest living bird .
Most taxonomic authorities recognize two extant species: the greater or American rhea (Rhea americana), and the lesser or Darwin's rhea (Rhea pennata). The International Union for Conservation of Nature (IUCN) classifies the puna rhea as another species instead of a subspecies of the lesser rhea. The IUCN currently rates the greater and puna ...
Matteuccia is a genus of ferns with one species: Matteuccia struthiopteris (common names ostrich fern, fiddlehead fern, or shuttlecock fern). [4] The species epithet struthiopteris comes from Ancient Greek words στρουθίων ( strouthíōn ) "ostrich" and πτερίς ( pterís ) "fern".
Although P. dmanisensis is known as the giant ostrich, its relationship to the extant ostriches of the genus Struthio is not clear. [1] [4] Some authors have suggested placing the large (albeit smaller than P. dmanisensis) extinct ostrich species Struthio anderssoni from the Late Pleistocene of China in the genus. [5]
