Résumé :	Although it had raised little interest at the time of publication [in 1883], the most recent British Ornithologists' Union checklist of British birds enumerated just 376 species. It included as full species Red-spotted and Whitespotted Bluethroat,White-throated and Black-bellied Dipper, British and White-headed Long-tailed Tit, British and Continental Coal Tit,White and Pied Wagtail,Yellow, Blue-headed and Grey-headed Wagtail,Two-barred and White-winged Crossbill, Northern and American Goshawk, and Gyr, Greenland and Iceland Falcon. Since then, both Siberian Stonechat and Siberian Chiffchaff have also been added to the list as full species. The next BOU checklist, due in a few years' time [it was published in 19 15], will have increased to 423 species and will see most of these pairs or groups lumped as single species. However,White and Pied Wagtail will remain as separate species, as will Yellow, Blue-headed and Black-headed Wagtail, Siberian Chiffchaff, Red Grouse and Yellow-legged Gull.
