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 (language), Portuguese); or ñandú (Guaraní language, Guaraní and Spanish language, Spanish). One of two species in the genus ''Rhea (bird), Rhea'', in the Family (biology), family Rheidae, it inhabits a variety of open areas, such as grasslands, savanna or grassy wetlands. Weighing , the greater rhea is the largest native bird 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 The greater rhea was Species description, formally described in 1758 by the Swedish naturalist Carl Linnaeus in the 10th edition of Systema Naturae, tenth edition of his ''Syst ...

Hinasuri
''Hinasuri'' is an extinct genus of rheid from the Montehermosan. Its fossils have been found in the Monte Hermoso Formation of Buenos Aires Province, Argentina. The type species In International_Code_of_Zoological_Nomenclature, 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 spe ... 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 {{Rheiformes-stub ...

Ratites
Ratites () are a polyphyletic group consisting of all birds within the infraclass Palaeognathae that lack keel (bird anatomy), keels and flightless bird, cannot fly. They are mostly large, long-necked, and long-legged, the exception being the Kiwi (bird), kiwi, which is also the only nocturnal extant ratite. The understanding of relationships within the paleognath clade has 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 Flying and gliding animals, flighted Neotropic tinamous (compare to Neognathae). Unlike other flightless birds, the ratites have no keel (bird), keel on their sternum—hence the name, from the Latin ('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 ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 occasionally two, with the emu splitting off into its own family, Dromaiidae. The IOC World Bird List and Cornell Lab of Ornithology's Birds of the World both do not recognize Dromaiidae, placing the emu in the family Casuariidae. 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 branch, 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 ...

Bird Families
This article lists living orders and families of birds. In total there are about 11,000 species of birds described as of 2024, though one estimate of the real number places it at almost 20,000. The order passerines (perching birds) alone accounts for well over 5,000 species. 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 Stiller ''et al'' (2024)., showing the 44 orders recognised by the IOC. Subclass Palaeognathae The Palaeognathae or "old jaws" is 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 were place in the order Struthioniformes. However, recent genetic analysis has found ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhea (bird)
The rhea ( ), also known as the ñandu ( ) or South American ostrich, is a South American ratite (flightless bird without a keel on the sternum bone) of the order Rheiformes. They are distantly related to the two African ostriches and Australia's emu (the largest, second-largest and third-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 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, having recovered from past threats to its survival. In addition, the feral population of the greater rhea in Germany appears to be growing. However, co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Opisthodactylus
''Opisthodactylus'' is an extinct genus of rheiform bird 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
Fossilworks was a portal which provides query, download, and analysis tools to facilitate access to the Paleobiology Database, a large relational database assembled by hundreds of paleontologists from around the world.
