I had a walk up there yesterday afternoon in the hope of perhaps Snow Bunting ! No success on that score but some very good habitat for them. Just lots of Red Grouse, 1 adult Herring Gull flyover>W and 9 Common Gulls >E.
It was good for walking on the top with soft snow on the surface and the ground underneath frozen so there were no bogs! Fantastic views all round. Not sure if I can get any photos on, though might try later.
It's worth a try up there in May for Dotterel !!
