The African ostrich is the largest living ratite. A large member of this species can be nearly 2.8 metres (9 ft 2 in) tall, weigh as much as 156 kilograms (344 lb), [18] and can outrun a horse. Of the living species, the Australian emu is next in height, reaching up to 1.9 metres (6 ft 3 in) tall and about 50 kilograms (110 lb). [18]

Ratites are a category of (mostly) large flightless birds of the order Struthioniformes. Subcategories This category has the following 10 subcategories, out of 10 total.
They are distantly related to the African ostriches and Australia's emu (the largest and second-largest living ratites, respectively), with rheas placing just behind the emu in height and overall size. Most taxonomic authorities recognize two extant species: the greater or American rhea (Rhea americana), and the lesser or Darwin's rhea (Rhea ...
Rheidae / ˈ r iː ɪ d iː / is a family of flightless ratite birds which first appeared in the Paleocene. [2] It is today represented by the sole living genus Rhea , but also contains several extinct genera.
The moas Dinornis robustus and Pachyornis elephantopus, tinamous' extinct ratite cousins from New Zealand. The tinamou family consists of 46 extant species in nine genera.The two subfamilies are the Nothurinae (also known as the Rhyncotinae), the steppe tinamous, and the Tinaminae, the forest tinamous. [5] "
The five extant species fall into the family Apterygidae (/ ˌ æ p t ə ˈ r ɪ dʒ ə d iː /) and genus Apteryx (/ ˈ æ p t ər ɪ k s /). [5] Approximately the size of a domestic chicken, kiwi are the smallest ratites (which also include ostriches, emus, rheas, cassowaries and the extinct elephant birds and moa).
The species is farmed in North America and Europe in a similar fashion to other ratites, such as the emu and ostrich. The main products are meat and eggs, but rhea oil is used for cosmetics and soaps, and rhea leather is also traded in quantity. Male greater rheas are very territorial during the breeding season.
