Hi Mike
Many thanks for your comment. I considered YLG but, was put off by the dark eyes I wondered whether it might be one of the ever increasing variants. . The black-backed/ yellow legged taxa is becoming increasingly complex with, it seems new sub-species and indeed full species appearing more and more.
Many thanks again.
