of the 1W male Caspian Stonechat in St Warne's Cove, St Agnes, Scilly.
This bird appears to show characteristics (mainly amount/extent of
white on inner webs of outertail feathers) associated with the north
Caspian taxon Saxicola maurus hemprichii (formerly variegatus).|
Compelling discussion on the taxonomy and nomenclature of 'Stonechats' in the Caspian region can be found in Svensson et al (2012)*.
