East Siberian Wagtail
Motacilla alba ocularis Swinhoe, 1860 (0, 1)
STATUS
Northern Siberia to north-west Alaska.
OVERVIEW
This first for Britain was found on the most northerly inhabited island of the British Isles.
A very fine dark eye-stripe that did not broaden at its rear end and a wholly grey rump and uppertail-coverts are starting points to identification.
