The journal Dutch Birding maintains a list of Western Palearctic bird species. The list is carefully constructed, following certain rules and new references, and is intended to be a more progressive list than that presented by the AERC. Note that the most recent update removed "introduced species with viable breeding populations of which all individuals or their ancestors certainly originate from captivity", so such species as Black Swan, Mandarin Duck, Rose-ringed Parakeet are no longer countable.
Unlike other authorities, Dutch Birding takes as its definition of the Western Palearctic "Europe with Macaronesia and all countries bordering the Black, Dead or Mediterranean Sea." This means that in the south, boundaries of countries are followed but areas of Mauritania or Chad that contain largely Palearctic avifaunas are omitted. Additionally, the definition excludes Armenia, Azerbaidjan, Iraq, Kuwait and Saudi Arabia.
