The list is based on Birds in Wales (Lovegrove et al. 1994), Birds in Wales 1992-2000 (Green 2002) and the list of the Welsh Ornithological Society (Prater & Thorpe 2006) with updates from the Welsh Records Panel's annual reports. The taxonomy and scientific names follow the official list of the British Ornithologists' Union (BOU). The English names are the vernacular names used in the 7th edition of the BOU list with the standardized names from that list given in brackets where they differ. The family introductions are based on The New Encyclopedia of Birds (Perrins 2004) except where otherwise stated. The number of species in each family is approximate due to differing opinions on classification; the numbers given in the list are based on The Clements Checklist of Birds of the World (Clements 2007).
Certain categories of birds are noted with the following tags:
The total number of species on the list is 435 including 133 British rarities, 65 Welsh rarities and 10 introduced species. About 150 species breed annually.
