List Of Birds Of Wales
This list of birds of Wales includes every species of bird that has been recorded in a wild state in Wales. Compared to the avifauna of Britain as a whole, Wales has fewer breeding species, but these include a number of moorland species such as red grouse and black grouse, large numbers of seabirds (particularly on offshore islands such as Skomer, Grassholm and Bardsey) and good populations of several species typical of Welsh oak woods including redstart, pied flycatcher and wood warbler.O'Shea (2000) Among the birds of prey is the red kite, which had become extinct in other parts of Britain until being reintroduced recently. In winter many wildfowl and waders are found around the coast, attracted by the mild temperatures. In spring and autumn a variety of migrant and vagrant birds can be seen, particularly on headlands and islands. Three-quarters of the UK population of the red-billed chough resides in Wales. The list is based on ''Birds in Wales'' (Lovegrove ''et al.'' 1994 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Milvus Milvus R(ThKraft)
''Milvus'' is a genus of medium-sized birds of prey. The genus was erected by the French naturalist Bernard Germain de Lacépède in 1799 with the red kite as the type species. The name is the Latin word for the red kite. Species This is an Old World group that forms part of the subfamily Milvinae. The genus contains three species. Allozyme data indicates that the genetic diversity in both black and red kites is rather low.Schreiber, Arnd; Stubbe, Michael & Stubbe, Annegret (2000): Red kite (''Milvus milvus'') and black kite (''M. migrans''): minute genetic interspecies distance of two raptors breeding in a mixed community (Falconiformes: Accipitridae). '' Biol. J. Linn. Soc.'' 69'(3): 351–365. (HTML abstract) Successful hybridization between ''Milvus'' kites is fairly commonplace, making mtDNA analyses unreliable to resolve the genus' phylogeny. Furthermore, there is no good correlation between molecular characters and biogeography and morphology in the red kite d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red Kite
The red kite (''Milvus milvus'') is a medium-large bird of prey in the family Accipitridae, which also includes many other Diurnality, diurnal Bird of prey, raptors such as eagles, buzzards, and harrier (bird), harriers. The species currently breeds in the Western Palearctic region of Europe and northwest Africa, though it formerly also occurred in northern Iran. It is resident in the milder parts of its range in western Europe and northwest Africa, but birds from northeastern and Central Europe winter further south and west, reaching south to Turkey. Vagrancy (biology), Vagrants have reached north to Finland and south to Israel, Libya and Gambia. Taxonomy The red kite was described by the Swedish naturalist Carl Linnaeus in 1758 in the 10th edition of Systema Naturae, 10th edition of his ''Systema Naturae'' under the Binomial nomenclature, binomial name ''Falco milvus''. The word ''milvus'' was the Latin name for the bird. In 1799 the French naturalist Bernard Germain de Lacép ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Introduced Species
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting. The Latin expression neobiota captures the characteristic that these species are ''new'' biota to their environment in terms of established biological network (e.g. food web) relationships. Neobiota can further be divided into neozoa (also: neozoons, sing. neozoon, i.e. animals) and n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vagrancy (biology)
Vagrancy is a phenomenon in biology whereby an individual animal (usually a bird) appears well outside its normal range; they are known as vagrants. The term accidental is sometimes also used. There are a number of poorly understood factors which might cause an animal to become a vagrant, including internal causes such as navigatory errors (endogenous vagrancy) and external causes such as severe weather (exogenous vagrancy). Vagrancy events may lead to colonisation and eventually to speciation. Birds In the Northern Hemisphere, adult birds (possibly inexperienced younger adults) of many species are known to continue past their normal breeding range during their spring migration and end up in areas further north (such birds are termed spring overshoots). In autumn, some young birds, instead of heading to their usual wintering grounds, take "incorrect" courses and migrate through areas which are not on their normal migration path. For example, Siberian passerines which normal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Ornithologists' Union
The British Ornithologists' Union (BOU) aims to encourage the study of birds (" ornithology") and around the world, in order to understand their biology and to aid their conservation. The BOU was founded in 1858 by Professor Alfred Newton, Henry Baker Tristram and other scientists. Its quarterly journal, '' Ibis'', has been published continuously since 1859. The Records Committee (BOURC) is a committee of the BOU established to maintain the British List, the official list of birds recorded in Great Britain. BOU is headquartered in Peterborough and is a registered charity in England & Wales and Scotland. Objectives and activities * Publishes '' Ibis'' as a leading international journal of ornithological science. * Organises a programme of meetings and conferences. * Awards grants and bursaries for ornithological research. * Encourages liaison between those actively engaged in ornithological research. * Provides a representative body of the scientific community able to p ...

Binomial Name
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxonomy (biology)
In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification intended to reflect the ...

Red-billed Chough
The red-billed chough, Cornish chough or simply chough ( ; ''Pyrrhocorax pyrrhocorax''), is a bird in the crow family, one of only two species in the genus '' Pyrrhocorax''. Its eight subspecies breed on mountains and coastal cliffs from the western coasts of Ireland and Britain east through southern Europe and North Africa to Central Asia, India and China. This bird has glossy black plumage, a long curved red bill, red legs, and a loud, ringing call. It has a buoyant acrobatic flight with widely spread primaries. The red-billed chough pairs for life and displays fidelity to its breeding site, which is usually a cave or crevice in a cliff face. It builds a wool-lined stick nest and lays three eggs. It feeds, often in flocks, on short grazed grassland, taking mainly invertebrate prey. Although it is subject to predation and parasitism, the main threat to this species is changes in agricultural practices, which have led to population decline, some local extirpation, and ran ...

Bird Migration
Bird migration is the regular seasonal movement, often north and south along a flyway, between breeding and wintering grounds. Many species of bird migrate. Migration carries high costs in predation and mortality, including from hunting by humans, and is driven primarily by the availability of food. It occurs mainly in the northern hemisphere, where birds are funneled onto specific routes by natural barriers such as the Mediterranean Sea or the Caribbean Sea. Migration of species such as storks, turtle doves, and swallows was recorded as many as 3,000 years ago by Ancient Greek authors, including Homer and Aristotle, and in the Book of Job. More recently, Johannes Leche began recording dates of arrivals of spring migrants in Finland in 1749, and modern scientific studies have used techniques including bird ringing and satellite tracking to trace migrants. Threats to migratory birds have grown with habitat destruction, especially of stopover and wintering sites, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
