Greater Rhea
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 (Portuguese); or ñandú (Guaraní and Spanish). One of two species in the genus '' Rhea'', in the family Rheidae, the greater rhea is native to Brazil, Bolivia, Argentina, Paraguay and Uruguay. It inhabits a variety of open areas, such as grasslands, savanna or grassy wetlands. Weighing , the greater rhea is the largest bird in South America and the largest native, extant bird anywhere in the Americas. In the wild, the greater rhea has a life expectancy of 10.5 years. It is also notable for its reproductive habits, and for the fact that a population has established itself in Northern Germany in recent years. The species is listed as Near Threatened by the IUCN. Taxonomy and systematics The greater rhea derives its scientific name from Rhea, a Greek goddess, and the Latinized form of America. It w ...

Ratite
A ratite () is any of a diverse group of flightless, large, long-necked, and long-legged birds of the infraclass Palaeognathae. Kiwi, the exception, are much smaller and shorter-legged and are the only nocturnal extant ratites. The systematics of and relationships within the paleognath clade have been in flux. Previously, all the flightless members had been assigned to the order Struthioniformes, which is more recently regarded as containing only the ostrich. The modern bird superorder Palaeognathae consists of ratites and the flighted Neotropic tinamous (compare to Neognathae). Unlike other flightless birds, the ratites have no keel on their sternum — hence the name, from the Latin ''ratis'' ( raft, a vessel which has no keel - in contradistinction to extant flighted birds with a keel). Without this to anchor their wing muscles, they could not have flown even if they developed suitable wings. Ratites are a paraphyletic group; tinamous fall within them, and are the sister ...

Hinasuri
''Hinasuri'' is an extinct genus of rhea from the Montehermosan. Its fossils have been found in the Monte Hermoso Formation of Buenos Aires Province, Argentina. The type species In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specim ... is ''H. nehuensis''. ''Hinasuri'' was a robust rheid bird, living at a time of increasingly extreme temperatures and decreased precipitation in the Pampean region during the Pliocene–Pleistocene.Picasso & Clelia Mosto, 2016 References Bibliography * Further reading * ''The Origin and Evolution of Birds'' by Alan Feduccia Ratites Pliocene birds of South America Montehermosan Neogene Argentina Fossils of Argentina Fossil taxa described in 1995 {{paleo-bird-stub ...

Bird Families
This article lists living orders and families of birds. The links below should then lead to family accounts and hence to individual species. The passerines (perching birds) alone account for well over 5,000 species. In total there are about 10,000 species of birds described worldwide, though one estimate of the real number places it at almost twice that. Taxonomy is very fluid in the age of DNA analysis, so comments are made where appropriate, and all numbers are approximate. In particular see Sibley-Ahlquist taxonomy for a very different classification. Phylogeny Cladogram of modern bird relationships based on Jarvis, E.D. et al. (2014) with some clade names after Yuri, T. et al. (2013). Paleognathae The Paleognathae, or "old jaws", are one of the two superorders recognized within the taxonomic class Aves and consist of the ratites and tinamous. The ratites are mostly large and long-legged, flightless birds, lacking a keeled sternum. Traditionally, all the ratites we ...

Rhea (bird)
The rheas ( ), also known as ñandus ( ) or South American ostriches, are large ratites (flightless birds without a keel on their sternum bone) in the order Rheiformes, native to South America, distantly related to the ostrich and emu. 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 rheas as near-threatened in their native ranges, while Darwin's rhea is of least concern. In addition, a feral population of the greater rhea in Germany appears to be growing, though control efforts are underway, and seem to be succeeding in controlling the birds' population growth. Etymology The name "rhea" was used in 1752 by Paul Möhring and adopted as the English common name. Möhring named ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Opisthodactylus
''Opisthodactylus'' is an extinct genus of rhea from the Early to Middle Miocene Santa Cruz and Chichinales Formations and the Late Miocene ( Montehermosan) Andalhuala Formation of Argentina. Three species are described: the type species, ''O. patagonicus'', ''O. kirchneri'' and ''O. horacioperezi''. The species ''O. kirchneri'' was described in 2017 by Noriega et al.''Opisthodactylus'' at Fossilworks

Casuariiformes
The Casuariiformes is an order of large flightless birds that has four surviving members: the three species of cassowary, and the only remaining species of emu. They are divided into either a single family, Casuariidae, or more typically two, with the emu splitting off into its own family, Dromaiidae. All four living members are native to Australia-New Guinea,Clements, J (2007) but some possible extinct taxa occurred in other landmasses. Systematics and evolution The emus form a distinct family, characterized by legs adapted for running. The total number of cassowary species described, based on minor differences in casque shape and color variations, formerly reached nine. Now, however, only three species are recognized, and most authorities only acknowledge few subspecies or none at all. The fossil record of casuariforms is interesting, but not very extensive. Regarding fossil species of '' Dromaius'' and '' Casuarius'', see their genus pages. As with all ratites, there are s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
