IRBC - The Irish List
The Irish List (as on the 31st December 2015) is available to download as a PDF document by following the link in the right-hand panel. The Irish List consists of all species included in Categories A, B & C (see below for a description of the Category system). The sequence and scientific nomenclature largely follows the IOC World List version 7.1 (Gill & Donsker 2017), replacing the previously referenced BOU British List.
New species are added to the Irish List following their publication in the Irish Rare Bird Report. Species may occasionally be removed from the list when the evidence no longer supports their inclusion. In addition, new data emerges from time to time which can recommend the splitting or lumping of existing species as well as revising the list order. Details of any changes in the Irish List are included in the Announcement pages.
Please note that the list includes four records which are not specifically identified, i.e. Madeiran, Monteiro's or Cape Verde Storm-petrel - Zino's, Fea's or Desertas Petrel - a Frigatebird species - Black or White-crowned Wheatear. When known, the relevant subspecies is included in the list. Monotypic species are indicated by a dash in the 'Subspecies' column.
National List Category System
The Association of European Rarities Committees (AERC) recommend the use of categories when compiling national lists of species. Many European rare bird committees now follow this practice including the IRBC. The following is a list of the categories in use and their significance:
- Category A
Species that have been recorded in an apparently natural state in Ireland at least once since 1st January 1950.
- Category B
Species that have been recorded in an apparently natural state in Ireland at least once up to 31st December 1949, but have not been recorded subsequently.
- Category C1
Species that, although originally introduced by man, have established feral breeding populations in Ireland which apparently maintain themselves without necessary recourse to further introduction.
- Category C2
Species that have occurred, but are considered to have originated from established naturalised populations outside Ireland.
- Category D1
Species that would otherwise appear in Categories A or B except that there is a reasonable doubt that they have ever occurred in a natural state.
- Category D2
Species that have arrived through ship or other human assistance.
- Category D3
Species that have only ever been found dead on the tideline.
- Category D4
Species that would otherwise appear in Category C1 except that their feral populations may or may not be self-supporting.
- Category E
Species that have been recorded as introductions, transportees or escapes from captivity.
The category breakdown of the Irish list on the 31st December 2014 was as follows:
- Category A - 461
- Category B - 14
- Category C - 3
- Total List - 478
- Category D - 11
- At Sea - 2
Species in Category D are not included in the main Irish List. Whenever a species is assigned to more than one category, the higher category only is included in the statistics. Category A is regarded as the highest.
