Ostriches are 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, cassowaries, kiwis and the extinct elephant birds and moas.
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 ...
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.
All Crypturellus are in the family Tinamidae, thus are classed as ratites, making them relatives of the cassowary, emu, kiwi, ostrich and rhea.Unlike these larger birds, however, tinamous still have the ability to fly, albeit somewhat weakly and not for prolonged periods (typically flying up, to perch on branches, when fleeing threats).
The largest ratite is the ostrich (Struthio camelus), from the plains of Africa and Arabia. A large male ostrich can reach a height of 2.8 m (9.2 ft) and weigh over 156 kg (344 lb). [49] A mass of 200 kg (440 lb) has been cited for the ostrich but no wild ostriches of this weight have been verified. [2]
The greater rhea (Rhea americana) is a species of flightless bird native to eastern South America.Other names for the greater rhea include the grey, common, or American rhea; ema (); or ñandú (Guaraní and Spanish).
