Northern Wheatears

A walk from Yesnaby north along cliffs to Bay of Skaill and Skara Brae. Always good for migrating wheatears, I eventually counted 12. All pretty distant, though, there's no cover to sneak up on them. One male was particularly vivid and long-legged, so maybe a Greenland race bird. Also seen- short-eared owl, guillemots, razorbills etc.
