Anthropoides
''Grus'' is a genus of large birds in the crane (bird), crane family. The genus ''Grus'' erected by the French zoologist Mathurin Jacques Brisson in 1760. The name ''Grus'' is the Latin word for "crane". The German ornithologist Peter Simon Pallas was sometimes credited with erecting the genus in 1766 but the International Commission on Zoological Nomenclature ruled in 1956 that Brisson should have priority. The genus formerly included additional species. A molecular phylogenetic study published in 2010 found that the genus ''Grus'', as then defined, was polyphyletic. In the resulting rearrangement to create monophyletic genera, the sandhill crane, the white-naped crane, the sarus crane and the brolga were moved to the resurrected genus ''Antigone (genus), Antigone'' that had been erected by the German naturalist Ludwig Reichenbach in 1853. The Siberian crane was moved to the resurrected monotypic genus ''Leucogeranus''. Species The genus contains eight species: The Handbo ...

Demoiselle Crane
The demoiselle crane (''Grus virgo'') is a species of crane found in central Eurosiberia, ranging from the Black Sea to Mongolia and Northeast China. There is also a small breeding population in Turkey. These cranes are migratory birds. Birds from western Eurasia will spend the winter in Africa while the birds from Asia, Mongolia and China will spend the winter in the Indian subcontinent. The bird is symbolically significant in the culture of India, where it is known as ''koonj'' or ''kurjaa''. Taxonomy The demoiselle crane was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae''. He placed it with the herons and cranes in the genus '' Ardea'' and coined the binomial name ''Ardea virgo''. He specified the type locality as the orient but this has been restricted to India. Linnaeus cited the accounts by earlier authors. The English naturalist Eleazar Albin had described and illustrated the "Numidian crane" in 1738. ...

Crane (bird)
Cranes are a type of large bird with long legs and necks in the Family (biology), biological family Gruidae of the Order (biology), order Gruiformes. The family has 15 species placed in four genera which are ''Antigone (genus), Antigone'', ''Balearica'', ''Siberian crane, Leucogeranus'', and ''Grus (genus), Grus''. They are large birds with long necks and legs, a tapering form, and long secondary feathers on the wing that project over the tail. Most species have muted gray or white plumages, marked with black, and red bare patches on the face, but the crowned cranes of the genus ''Balearica'' have vibrantly-coloured wings and golden "crowns" of feathers. Cranes fly with their necks extended outwards instead of bent into an S-shape and their long legs outstretched. Cranes live on most continents, with the exception of Antarctica and South America. Some species and populations of cranes bird migration, migrate over long distances; others do not migrate at all. Cranes are solitary du ...

Siberian Crane
The Siberian crane (''Leucogeranus leucogeranus''), also known as the Siberian white crane or the snow crane, is a bird of the family Gruidae, the crane (bird), cranes. They are distinctive among the cranes: adults are nearly all White, snowy white, except for their black Flight feather, primary feathers that are visible in flight, and with two Population ecology, breeding populations in the Arctic tundra of western and Russian Far East, eastern Russia. The eastern populations bird migration, migrate during winter to China, while the western population winters in Iran and (formerly) in Bharatpur district, Bharatpur, India. Among the cranes, they make the longest distance Animal migration, migrations. Their populations, particularly those in the western range, have declined drastically in the 20th century due to Fowling, hunting along their migration routes and habitat destruction, habitat degradation.

Common Crane
The common crane (''Grus grus''), also known as the Eurasian crane, is a bird of the family Gruidae, the crane (bird), cranes. A medium-sized species, it is the only crane commonly found in Europe besides the demoiselle crane (''Grus virgo'') and the Siberian crane (''Leucogeranus leucogeranus'') that only are regular in the far eastern part of the continent. Along with the sandhill crane (''Antigone canadensis''), demoiselle crane and the brolga (''Antigone rubicunda''), it is one of only four crane species not currently classified as threatened with extinction or conservation dependent on the species level. Despite the species' large numbers, local extinctions and extirpations have taken place in part of its range, and an ongoing Reintroduction of a species, reintroduction project is underway in the United Kingdom. Taxonomy The first Species description, formal description of the common crane was by the Swedish naturalist Carl Linnaeus in 1758 in the 10th edition of Systema Nat ...

Ludwig Reichenbach
Heinrich Gottlieb Ludwig Reichenbach (8 January 1793 – 17 March 1879) was a German botanist, ornithologist and illustrator. It was he who first requested Leopold and Rudolf Blaschka, 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, becoming a professor and, eight years later in 1818, an instructor. 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. Together with Carl Friedrich Heinrich Schubert he started in 1822 to edit and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Siberia
Siberia ( ; , ) is an extensive geographical region comprising all of North Asia, from the Ural Mountains in the west to the Pacific Ocean in the east. It has formed a part of the sovereign territory of Russia and its predecessor states since the lengthy conquest of Siberia, which began with the fall of the Khanate of Sibir in 1582 and concluded with the annexation of Chukotka in 1778. Siberia is vast and sparsely populated, covering an area of over , but home to roughly a quarter of Russia's population. Novosibirsk, Krasnoyarsk, and Omsk are the largest cities in the area. Because Siberia is a geographic and historic concept and not a political entity, there is no single precise definition of its territorial borders. Traditionally, Siberia spans the entire expanse of land from the Ural Mountains to the Pacific Ocean, with the Ural River usually forming the southernmost portion of its western boundary, and includes most of the drainage basin of the Arctic Ocean.

Eurasia
Eurasia ( , ) is a continental area on Earth, comprising all of Europe and Asia. According to some geographers, Physical geography, physiographically, Eurasia is a single supercontinent. The concept of Europe and Asia as distinct continents dates back to classical antiquity, antiquity, but their borders have historically been subject to change. For example, the ancient Greeks originally included Africa in Asia but classified Europe as separate land. Eurasia is connected to Africa at the Suez Canal, and the two are sometimes combined to describe the largest contiguous landmass on Earth, Afro-Eurasia. History Eurasia has been the host of many ancient civilizations, including those based in Mesopotamia, Egypt, the Indus Valley and China. In the Axial Age (mid-first millennium BCE), a continuous belt of civilizations stretched through the Eurasian Subtropics, subtropical zone from the Atlantic to the Pacific. This belt became the mainstream of world history for two millennia. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
