Hi Joe,
welcome to WAB!
ChrisJB has just been up to Mull, so he should have some good recent info - you should get most of those birds up there, good luck with corncrake! - not sure though if Ptarmigan are on Ben More, although its a Munroe and they usually like over 2000ft, they also prefer rocky and I dont know the high tops on that side enough to recommend, but no doubt others will.
Cairngorms and Ben Lawers too far I guess!
Have a great time and let us know what you find.
Cheers
Ken
