Surfbirders may be interested in some of the new 'splits' published in the recent Dutch Birding (DB 31: 35-37, 2009).
Middendorff's Bean Goose Anser middendorffi - now treated as separate from both Tundra Bean A. fabalis (fabalis and johanseni) and Taiga Bean Goose A. serrirostris (serrirostris and rossicus)
Lilith's Owl Athene glaux - now treated as separate from Little Owl Athene noctua, and is polytypic (glaux, indigena and lilith) with a distribution running from N Africa, east to the Middle East and from southern Romania, east through Turkey to SW Siberia. The Howard and Moore checklist (Dickinson, 2003) lists indigena as running south from Albania, through Greece, Turkey and northern Levant; lilith occurs in Cyprus also.
Eastern Nightingale - the easternmost form previously treated as the subspecies hafizi, is now named golzii
Siberian Thrush - new scientific name is Geokichla sibirica
Southern Grey Shrike Lanius meridionalis - the population from Southern France, Spain and Portugal meridionalis is now treated as monotypic(better as 'Iberian Grey Shrike', perhaps?); koenigi from the Canary Islands is not conspecific with meridionalis, but is genetically linked with algeriensis in N Africa - all other subspecies are currently subsumed within Desert Grey Shrike L. elegans. According to DB, there are now four species of grey shrike in the WP, Great Grey, Southern/Iberian Grey, Desert Grey, and Steppe Grey Shrike L. pallidirostris.
Moltoni's Warbler Sylvia subalpina - now split from Subalpine Warbler S. cantillans, following studies of its geographical distribution, voice and morphology.
