Pyrrhula Erythaca
The grey-headed bullfinch (''Pyrrhula erythaca'') is a species of finch in the family Fringillidae. It is sometimes known as Beavan's bullfinch. It is found in Bhutan, China, India, Myanmar, and Nepal. Its natural habitats are boreal forest and temperate forest. Taxonomy Molecular phylogeny indicates that species of the genus '' Pyrrhula'' have a common ancestor with the pine grosbeak (''Pinicola enucleator'').

Edward Blyth
Edward Blyth (23 December 1810 – 27 December 1873) was an English zoologist who worked for most of his life in India as a curator of zoology at the museum of the Asiatic Society of India in Calcutta. Blyth was born in London in 1810. In 1841 he travelled to India to become the curator of the museum of the Asiatic Society, Royal Asiatic Society of Bengal. He set about updating the museum's catalogues, publishing a ''Catalogue of the Birds of the Asiatic Society'' in 1849. He was prevented from doing much fieldwork himself, but received and described bird specimens from Allan Octavian Hume, A.O. Hume, Samuel Tickell, Robert Swinhoe and others. He remained as curator until 1862, when ill-health forced his return to England. His ''Natural History of the Cranes'' was published posthumously in 1881. Avian species bearing his name include Blyth's hornbill, Blyth's leaf warbler, Blyth's hawk-eagle, Blyth's olive bulbul, Blyth's parakeet, Blyth's frogmouth, Blyth's reed warbler, Blyth ...

Pyrrhula Erythaca Erythaca 1863
Pyrrhula is a small genus of passerine birds, commonly called bullfinches, belonging to the finch family (Fringillidae). The genus has a Palearctic distribution; almost all species occur in Asia, with two species exclusively in the Himalayas and one species, ''P. pyrrhula'', also occurring in Europe. The Azores bullfinch (''P. murina'') is a critically endangered species (about 120 pairs remaining), occurring only in the east of the island of São Miguel in the Azores archipelago. Analysis of the mtDNA cytochrome ''b'' sequence indicates that the Holarctic pine grosbeak (''Pinicola enucleator'') is the closest living relative of this genus. Arguably, it could be included in ''Pyrrhula'', but more probably is a distinct offshoot of a common ancestor, with the pine grosbeak as the sister group to the ancestor of the bullfinches. The evolution of the bullfinch species started soon after the pine grosbeak's ancestors diverged from them (at the end of the Middle Miocene, about 12 ...

Birds Described In 1862
Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the Common ostrich, ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Birds Of China
This is a list of the bird species recorded in China. The avifauna of China include a total of 1425 species, of which 57 are endemic, and 3 have been introduced by humans. Of these, 108 species are globally threatened. This list's taxonomic treatment (designation and sequence of orders, families and species) and nomenclature (common and scientific names) follow the conventions of '' The Clements Checklist of Birds of the World'', 2022 edition. The family accounts at the beginning of each heading reflect this taxonomy, as do the species counts found in each family account. Introduced and accidental species are included in the total counts for China. The following tags have been used to highlight several categories. The commonly occurring native species do not fall into any of these categories. * (A) Accidental - a species that rarely or accidentally occurs in China * (E) Endemic - a species native or restricted to China * (I) Introduced - a species introduced to China as a c ...

Pine Grosbeak
The pine grosbeak (''Pinicola enucleator'') is a large member of the true finch family, Fringillidae. It is the only species in the genus ''Pinicola''. It is found in coniferous woods across Alaska, the western mountains of the United States, Canada, and in subarctic Fennoscandia and across the Palearctic to Siberia. The species is a frugivore, especially in winter, favoring small fruits, such as rowans (mountain-ashes in the New World). With fruit-crop abundance varying from year to year, pine grosbeak is one of many subarctic-resident bird species that exhibit irruptive behavior. In irruption years, individuals can move long distances in search of suitable food supplies, bringing them farther south and/or downslope than is typical of years with large fruit crops. Taxonomy The pine grosbeak was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae'' under the binomial name ''Loxia enucleator''. The type locality is S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bouvreuil Tête Grise – Pyrrhula Erythaca – Eure 26- 222
Rouen Castle (''Château Bouvreuil'') was a fortified ducal and royal residence in the city of Rouen, capital of the duchy of Normandy, now in France. With the exception of the tower wrongly associated with Joan of Arc, which was restored by Viollet-le-Duc, the castle was destroyed at the end of the 16th century, its stones quarried for other construction. History The castle was built by Philip II of France from 1204 to 1210 following his capture of the duchy from John, Duke of Normandy and King of England. Located outside the medieval town to its north, in a dominant position, it played a military role in the Hundred Years' War and the Wars of Religion. It was the main seat of power, administration and politics in the duchy of Normandy for nearly 400 years, symbolically replacing the ducal palace of Rouen in these roles – of the bailliage and vicomté of the king of France, of the English government of the area (1418–1449), of the échiquier de Normandie (which became the ...

Temperate
In geography, the temperate climates of Earth occur in the middle latitudes (23.5° to 66.5° N/S of Equator), which span between the tropics and the polar regions of Earth. These zones generally have wider temperature ranges throughout the year and more distinct seasonal changes compared to tropical climates, where such variations are often small and usually only have precipitation changes. In temperate climates, not only do latitudinal positions influence temperature changes, but sea currents, prevailing wind direction, continentality (how large a landmass is) and altitude also shape temperate climates. The Köppen climate classification defines a climate as "temperate" C, when the mean temperature is above but below in the coldest month to account for the persistency of frost. However, other climate classifications set the minimum at . Zones and climates The north temperate zone extends from the Tropic of Cancer (approximately 23.5° north latitude) to the Arctic ...

Species
In biology, a species is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
