Great Grey Shrike sighting Scotland!

Hi to you all. I’m new to this sight and have had to set up an account purely on the grounds of my sighting! Having had a long day in the Mountains I returned to the small car park at the end of Loch Ericht yesterday and was stunned to see a Shrike sitting on a fence post. I watched him for some time darting into the rough ground and returning to the post several times. I got a poor photo of him on some barbed wire. I know there are few if no sightings of this bird in this or indeed the West of Scotland. However I am fairly confident of my identification. If anyone is visiting the area I would be very grateful if they could report if they can confirm a sighting. I’m also happy to be corrected on the identification. I’ll add the poor photograph for your thoughts please.
