Antigone (genus)
''Antigone'' is a genus of large birds in the crane family. The species in this genus were formerly placed in the genus '' Grus''. Taxonomy A molecular phylogenetic study published in 2010 found that the genus '' Grus'' was polyphyletic. In the subsequent rearrangement, four species were placed in the resurrected genus ''Antigone''. The genus had initially been erected in 1853 by German naturalist Ludwig Reichenbach. 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 specime ... is the sarus crane (''Antigone antigone'').

1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Brolga
The brolga (''Antigone rubicunda''), formerly known as the native companion, is a bird in the crane family. It has also been given the name Australian crane, a term coined in 1865 by well-known ornithologist John Gould in his ''Birds of Australia''. The brolga is a common, gregarious wetland bird species of tropical and south-eastern Australia and New Guinea. It is a tall, upright bird with a small head, long beak, slender neck, and long legs. Its plumage is mainly grey, with black wing tips, and it has an orange-red band on its head. The brolga's courting dance is similar to that of other cranes. The nest is built of wetland vegetation, either on an elevated piece of land or floating on shallow water in marshland, and usually two eggs are laid. Incubation takes 32 days, and the newly hatched young are precocial. The adult diet is omnivorous and includes plant matter, invertebrates, and small vertebrates. Although the bird is not considered endangered over the majority of its r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sarus Crane (Grus Antigone)
The sarus crane (''Antigone antigone'') is a large nonmigratory crane found in parts of the Indian subcontinent The Indian subcontinent is a list of the physiographic regions of the world, physiographical region in United Nations geoscheme for Asia#Southern Asia, Southern Asia. It is situated on the Indian Plate, projecting southwards into the Indian O ..., Southeast Asia, and Australia. The tallest of the flying birds, standing at a height of up to , they are a conspicuous species of open wetlands in South Asia, seasonally flooded ''Dipterocarpus'' forests in Southeast Asia, and ''Eucalyptus''-dominated woodlands and grasslands in Australia. The sarus crane is easily distinguished from other cranes in the region by its overall grey colour and the contrasting red head and upper neck. They forage on marshes and shallow wetlands for roots, tubers, insects, crustaceans, and small vertebrate prey. Like other cranes, they form long-lasting pair bonds and maintain territories ...

White-naped Crane
The white-naped crane (''Antigone vipio'') is a bird of the crane family. It is a large bird, long, about tall, and weighing about , with pinkish legs, a grey-and-white-striped neck, and a red face patch. Distribution The white-naped crane breeds in northeastern Mongolia, northeastern China, and adjacent areas of southeastern Russia, where a program at Khingan Nature Reserve raises eggs provided from U.S. zoos to bolster the species. Different groups of the birds migrate to winter near the Yangtze River, the Korean Demilitarized Zone, and on Kyūshū in Japan. They are the only cranes found in South Korea. They also reach Kazakhstan and Taiwan. Only about 4,900 to 5,400 individuals remain in the wild. Its diet consists mainly of insects, seeds, roots, plants, and small animals. Due to ongoing habitat loss and overhunting in some areas, the white-naped crane is evaluated as vulnerable on the IUCN Red List of Threatened Species. It is listed on Appendix I and II of CITES.

Sandhill Crane
The sandhill crane (''Antigone canadensis'') is a species of large crane of North America and extreme northeastern Siberia. The common name of this bird refers to habitat like that at the Platte River, on the edge of Nebraska's Sandhills on the American Great Plains. Sandhill Cranes are known to hangout at the edges of bodies of water especially in the Central Florida region. This is the most important stopover area for the nominotypical subspecies, the lesser sandhill crane (''A. c. canadensis''), with up to 450,000 of these birds migrating through annually. Taxonomy In 1750, English naturalist George Edwards included an illustration and a description of the sandhill crane in the third volume of his ''A Natural History of Uncommon Birds''. He used the English name "The Brown and Ash-colour'd Crane". Edwards based his hand-coloured etching on a preserved specimen that had been brought to London from the Hudson Bay area of Canada by James Isham. When in 1758 the Swedish natu ...

Ludwig Reichenbach
Heinrich Gottlieb Ludwig Reichenbach (8 January 1793 – 17 March 1879) was a German botanist and ornithologist. It was he who first requested Leopold Blaschka to make a set of glass marine invertebrate models for scientific education and museum showcasing, the successful commission giving rise to the creation of the Blaschkas' Glass sea creatures and, subsequently and indirectly, the more famous Glass Flowers. Early life Born in Leipzig and the son of Johann Friedrich Jakob Reichenbach (the author in 1818 of the first Greek-German dictionary) Reichenbach studied medicine and natural science at the University of Leipzig in 1810 and, eight years later in 1818, he the now Professor became an instructor before, in 1820, he was appointed the director of the Dresden natural history museum and a professor at the Surgical-Medical Academy in Dresden, where he remained for many years. Glass sea creatures Director of the natural history museum in Dresden, Professor Reichenbach was fac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.
