List of birds of Ireland

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, 6th 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.
