Does anyone know where the name "East Siberian" Wagtail came from for Motacilla alba ocularis? The earliest we can find is from Dutch Birding around 1998, such as https://crbpo.mnhn.fr/IMG/pdf/Sangster_et_al_1999_CSNA_1977-98_ARDEA.pdf , so does it originate there? No mention of it in Alstrom & Mild's Pipits and Wagtails, and its not called this in IOC or eBird. Quite rightly in my view, as its an awful name and not particularly correct. Why not simply "Siberian", or even better "Swinhoe's"?
