Chillingham Cattle
Chillingham cattle, also known as Chillingham wild cattle, are a breed of cattle that live in a large enclosed park at Chillingham Castle, Northumberland, England. In summer 2022 the cattle numbers 138 animals with approximately equal numbers of males and females The herd has remained remarkably genetically isolated for hundreds of years, surviving despite inbreeding depression due to the small population. There is also a small reserve herd of about 20 animals located on Crown Estate land near Fochabers, North East Scotland. Description of cattle The Chillingham cattle are related to White Park cattle, in the sense that the Chillingham herd has contributed to the White Park, though there has been no gene flow the other way. Chillingham cattle are small, with upright horns in both males and females. Bulls weigh around , cows about . They are white with coloured ears (they may also have some colour on feet, nose and around the eyes). In the case of Chillingham cattle, the ...

Northumberland
Northumberland () is a county in Northern England, one of two counties in England which border with Scotland. Notable landmarks in the county include Alnwick Castle, Bamburgh Castle, Hadrian's Wall and Hexham Abbey. It is bordered by land on three sides; by the Scottish Borders region to the north, County Durham and Tyne and Wear to the south, and Cumbria to the west. The fourth side is the North Sea, with a stretch of coastline to the east. A predominantly rural county with a landscape of moorland and farmland, a large area is part of Northumberland National Park. The area has been the site of a number of historic battles with Scotland. Name The name of Northumberland is recorded as ''norð hẏmbra land'' in the Anglo-Saxon Chronicle, meaning "the land north of the Humber". The name of the kingdom of ''Northumbria'' derives from the Old English meaning "the people or province north of the Humber", as opposed to the people south of the Humber Estuary. History ...

Biodiversity
Biodiversity or biological diversity is the variety and variability of life on Earth. Biodiversity is a measure of variation at the genetic (''genetic variability''), species (''species diversity''), and ecosystem (''ecosystem diversity'') level. Biodiversity is not distributed evenly on Earth; it is usually greater in the tropics as a result of the warm climate and high primary productivity in the region near the equator. Tropical forest ecosystems cover less than 10% of earth's surface and contain about 90% of the world's species. Marine biodiversity is usually higher along coasts in the Western Pacific, where sea surface temperature is highest, and in the mid-latitudinal band in all oceans. There are latitudinal gradients in species diversity. Biodiversity generally tends to cluster in hotspots, and has been increasing through time, but will be likely to slow in the future as a primary result of deforestation. It encompasses the evolutionary, ecological, and cultural ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eurasian Nuthatch
The Eurasian nuthatch or wood nuthatch (''Sitta europaea'') is a small passerine bird found throughout the Palearctic and in Europe. Like other nuthatches, it is a short-tailed bird with a long bill, blue-gray upperparts and a black eye-stripe. It is a vocal bird with a repeated loud ''dwip'' call. There are more than 20 subspecies in three main groups; birds in the west of the range have orange-buff underparts and a white throat, those in Russia have whitish underparts, and those in the east have a similar appearance to European birds, but lack the white throat. Its preferred habitat is mature deciduous or mixed woodland with large, old trees, preferably oak. Pairs hold permanent territories, and nest in tree holes, usually old woodpecker nests, but sometimes natural cavities. If the entrance to the hole is too large, the female plasters it with mud to reduce its size, and often coats the inside of the cavity too. The 6–9 red-speckled white eggs are laid on a deep base of pin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Green Woodpecker
The European green woodpecker (''Picus viridis'') is a large green woodpecker with a bright red crown and a black moustache. Males have a red centre to the moustache stripe which is absent in females. It is resident across much of Europe and the western Palearctic but in Spain and Portugal it is replaced by the similar Iberian green woodpecker (''Picus sharpei''). The European green woodpecker spends much of its time feeding on ants on the ground and does not often 'drum' on trees like other woodpecker species. Though its vivid green and red plumage is particularly striking, it is a shy bird, and is more often heard than seen, drawing attention with its loud calls. A nest hole is excavated in a tree; four to six eggs are laid which hatch after 19–20 days. Taxonomy The European green woodpecker was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under its current binomial name ''Picus viridis''.

Common Buzzard
The common buzzard (''Buteo buteo'') is a medium-to-large bird of prey which has a large range. A member of the genus ''Buteo'', it is a member of the family Accipitridae. The species lives in most of Europe and extends its breeding range across much of the Palearctic as far as northwestern China (Tian Shan), far western Siberia and northwestern Mongolia.Ferguson-Lees, J., & Christie, D. A. (2001). ''Raptors of the world''. Houghton Mifflin Harcourt. Over much of its range, it is a year-round resident. However, buzzards from the colder parts of the Northern Hemisphere as well as those that breed in the eastern part of their range typically migrate south for the northern winter, many journeying as far as South Africa.Bildstein, K. L., & Zalles, J. I. (2005). ''Old World versus New World long-distance migration in accipiters, buteos, and falcons''. Birds of two worlds: the ecology and evolution of migration.

Bird
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the 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 loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. B ...

Fallow Deer
''Dama'' is a genus of deer in the subfamily Cervinae, commonly referred to as fallow deer. Name The name fallow is derived from the deer's pale brown colour. The Latin word ''dāma'' or ''damma'', used for roe deer, gazelles, and antelopes, lies at the root of the modern scientific name, as well as the German ''Damhirsch'', French ''daim'', Dutch ''damhert'', and Italian ''daino''. In Croatian and Serbian, the name for the fallow deer is ''jelen lopatar'' ("shovel deer"), due to the form of its antlers. The Modern Hebrew name of the fallow deer is ''yachmur'' (יחמור). Taxonomy and evolution The genus includes two extant species: Extant species Some taxonomists include the Persian fallow deer as a subspecies In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed.

Roe Deer
The roe deer (''Capreolus capreolus''), also known as the roe, western roe deer, or European roe, is a species of deer. The male of the species is sometimes referred to as a roebuck. The roe is a small deer, reddish and grey-brown, and well-adapted to cold environments. The species is widespread in Europe, from the Mediterranean to Scandinavia, from Scotland to the Caucasus, and east to northern Iran and Iraq. Etymology English ''roe'' is from Old English ''rā'' or ''rāha'', from Proto-Germanic ''*raihô'', cognate with Old Norse ''rá'', Old Saxon ''rēho'', Middle Dutch and Dutch ''ree'', Old High German ''rēh'', ''rēho'', ''rēia'', German ''Reh''. It is perhaps ultimately derived from a PIE root ''*rei-'', meaning "streaked, spotted or striped". The word is attested on the 5th-century Caistor-by-Norwich astragalus -a roe deer talus bone, written in Elder Futhark as , transliterated as ''raïhan''. In the English language, this deer was originally simply called a 'roe', b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Badger
Badgers are short-legged omnivores in the family Mustelidae (which also includes the otters, wolverines, martens, minks, polecats, weasels, and ferrets). Badgers are a polyphyletic rather than a natural taxonomic grouping, being united by their squat bodies and adaptions for fossorial activity. All belong to the caniform suborder of carnivoran mammals. The fifteen species of mustelid badgers are grouped in four subfamilies: four species of Melinae (genera ''Meles'' and ''Arctonyx'') including the European badger, five species of Helictidinae (genus ''Melogale'') or ferret-badger, the honey badger or ratel Mellivorinae (genus ''Mellivora''), and the American badger Taxideinae (genus ''Taxidae''). Badgers include the most basal mustelids; the American badger is the most basal of all, followed successively by the ratel and the Melinae; the estimated split dates are about 17.8, 15.5 and 14.8 million years ago, respectively. The two species of Asiatic stink badgers of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red Squirrel
The red squirrel (''Sciurus vulgaris'') is a species of tree squirrel in the genus ''Sciurus'' common throughout Europe and Asia. The red squirrel is an arboreal, primarily herbivorous rodent. In Great Britain, Ireland, and in Italy numbers have decreased drastically in recent years. This decline is associated with the introduction by humans of the eastern grey squirrel (''Sciurus carolinensis'') from North America. However, the population in Scotland is stabilising due to conservation efforts, awareness and the increasing population of the pine marten, a European predator that selectively controls grey squirrels. Description The red squirrel has a typical head-and-body length of , a tail length of , and a mass of . Males and females are the same size. The red squirrel is somewhat smaller than the eastern grey squirrel which has a head-and-body length of and weighs between . The long tail helps the squirrel to balance and steer when jumping from tree to tree and running ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of 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 produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, 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 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 specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Britain
Great Britain is an island in the North Atlantic Ocean off the northwest coast of continental Europe. With an area of , it is the largest of the British Isles, the largest European island and the ninth-largest island in the world. It is dominated by a maritime climate with narrow temperature differences between seasons. The 60% smaller island of Ireland is to the west—these islands, along with over 1,000 smaller surrounding islands and named substantial rocks, form the British Isles archipelago. Connected to mainland Europe until 9,000 years ago by a landbridge now known as Doggerland, Great Britain has been inhabited by modern humans for around 30,000 years. In 2011, it had a population of about , making it the world's third-most-populous island after Java in Indonesia and Honshu in Japan. The term "Great Britain" is often used to refer to England, Scotland and Wales, including their component adjoining islands. Great Britain and Northern Ireland now constitute the ...
