I'm off to the Cairngorms for a couple of days at the end of April and was wondering if anyone knew the good areas to see interesting species. I'm guessing capercaillie will be tricky, but cresties, parrot crossbills, ptarmigan etc should be possible I'd hope. I'm based in Braemar and will be hiking in the hills for a couple of days, but should also have time for a car-based excursion at some point. Any help would be gratefully received!
