I guess most WP listers use the boundaries as defined in Birds of the Western Palearctic (BWP), so in effect a biogeographic zone is being used as a fixed area. I guess the publication of BWP was also the reason birders start keeping WP lists in the first place. I guess (again) that at that time the WP basically contained all those countries easily accessible to European birders, hence keeping a WP list was perhaps a bit more attractive than keeping a Europe list.</blockquote>
