ñandú
The rheas ( ), also known as ñandus ( ) or South American ostriches, are large ratites (flightless birds without a keel (bird anatomy), keel on their sternum bone) in the order Rheiformes, native to South America, distantly related to the Common ostrich, ostrich and emu. Most taxonomic authorities recognize two extant species: the Greater rhea, greater or American rhea (''Rhea americana''), and the Darwin's rhea, 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 Mö ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lesser Rhea
Darwin's rhea or the lesser rhea (''Rhea pennata'') is a large flightless bird, the smaller of the two extant species of rheas. It is found in the Altiplano and Patagonia in South America. Description The lesser rhea stands at tall. Length is and weight is . Like most ratites, it has a small head and a small bill, the latter measuring , but has long legs and a long neck. It has relatively larger wings than other ratites, enabling it to run particularly well. It can reach speeds of 60 km/h (37 mph), enabling it to outrun predators. The sharp claws on the toes are effective weapons. Their feathers are similar to those of ostriches, in that they have no aftershaft.Perrins, C. (1987) Their plumage is spotted brown and white, and the upper part of their tarsus is feathered. The tarsus is long and has 18 horizontal plates on the front. Etymology It is known as ''ñandú petiso'', or ''ñandú del norte'', in Argentina, where the majority live. Other names are ''s ...

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 (Guaranà 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 was ...

Paul Möhring
Paul Heinrich Gerhard Möhring (also Paul Mohr; 21 July 1710 in Jever – 28 October 1792) was a German physician, botanist and zoologist. He studied medicine in Danzig and Wittenberg, and following graduation (1733), he settled as a general practitioner in his hometown of Jever. Möhring was a physician to the Prince of Anhalt. In 1752 he published '' Avium Genera'', an early attempt to classify bird species, which divided birds into four classes and shows the beginnings of the modern groupings. During his long career, he maintained correspondence with Albrecht von Haller, Lorenz Heister, Carl Linnaeus, Hans Sloane and Paul Gottlieb Werlhof. The plant genus ''Moehringia'' (family Caryophyllaceae Caryophyllaceae, commonly called the pink family or carnation family, is a family of flowering plants. It is included in the dicotyledon order Caryophyllales in the APG III system, alongside 33 other families, including Amaranthaceae, Cactacea ...) was named in his honor by Carl L ...

Common Ostrich
The common ostrich (''Struthio camelus''), or simply ostrich, is a species of flightless bird native to certain large areas of Africa and is the largest living bird species. It is one of two extant species of ostriches, the only living members of the genus ''Struthio'' in the ratite order of birds. The other is the Somali ostrich (''Struthio molybdophanes''), which was recognized as a distinct species by BirdLife International in 2014 having been previously considered a distinctive subspecies of ostrich. The common ostrich belongs to the order (biology), order Struthioniformes. Struthioniformes previously contained all the ratites, such as the Kiwi (bird), kiwis, emus, Rhea (bird), rheas, and Cassowary, cassowaries. However, recent genetic analysis has found that the group is not monophyletic, as it is paraphyletic with respect to the tinamous, so the ostriches are now classified as the only members of the order. Phylogenetic studies have shown that it is the sister group to all ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
