I suppose it's possible they or their ancestors made their own way across from Sweden or Norway in a storm, but grouse don't generally move away from where they were born according to my books.

I'm about to head out the same way so will take a camera with me just in case.

I've seen plenty of Ptarmigan and it could be one of those I guess but I've never seen one pure white before, no grey specs any where
