This is a list of the bird species recorded in Ireland. The avifauna of Ireland include a total of 466 species, of which two have been introduced by humans, 255 are rare or accidental and one occurs as both an introduced species and an accidental. Thirteen species are globally threatened. One is extinct. Ireland has a relatively low diversity of breeding birds due to its isolation. Several species such as the tawny owl, Eurasian nuthatch and willow tit which breed in Great Britain have not been recorded. However, there are large colonies of seabirds including important populations of European storm petrels, northern gannets and roseate terns. Other notable breeding birds include corn crakes and red-billed choughs. There are no endemic species but there are endemic subspecies of white-throated dipper, coal tit and Eurasian jay. Large numbers of wildfowl and waders winter in Ireland, attracted by its mild climate. About half the world population of Greenland white-fronted geese spend the winter there. During autumn, many migrating seabirds can be seen off the coasts including several species of skuas, shearwaters and petrels. Ireland's westerly position means that North American birds are regularly recorded in autumn. This list's taxonomic treatment (designation and sequence of orders, families and species) and nomenclature (common and scientific names) largely follow the conventions of ''The Clements Checklist of Birds of the World'', 5th edition although some names more commonly used by Irish birdwatchers are taken from the Irish Rare Birds Committee (IRBC) list. The family accounts at the beginning of each heading reflect the Clements taxonomy, as do the species counts found in each family account. Introduced and accidental species are included in the total counts for Ireland. The total includes three examples of birds that have been accepted onto the official list without being identified to species: frigatebird species, Fea's or Zino's petrel and black or white-tailed wheatear. The total does not include species placed in Category D of the Irish list. These are species where there is doubt as to whether they have occurred in a wild state (Category D1), they have arrived by human assistance such as on board a ship (D2), they have only been recorded dead on the tideline (D3) or they are feral species whose populations may not be self-sustaining (D4). The following tags have been used to highlight several categories, but not all species fall into one of these categories. Those that do not, are commonly occurring native species. *(A) Accidental - a species that rarely or accidentally occurs in Ireland *(I) Introduced - a species introduced to Ireland as a consequence, direct or indirect, of human actions *(E) Extirpated - a species which no longer exists in Ireland, but which exists elsewhere __NOTOC__ ==Divers== Order: GaviiformesFamily: Gaviidae Divers, also known as loons, are a group of aquatic birds found in many parts of North America and northern Europe. They are the size of a large duck or small goose, which they somewhat resemble in shape when swimming, but to which they are completely unrelated. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「List of birds of Ireland」の詳細全文を読む スポンサード リンク
