I used to see them regularly on the Hornbeam at Abernyte Farmhouse, but haven't seen them there for a couple of years. The Forewood above Whitehills still has a good number and the recent efforts there to reduce the number of greys has helped that.
Not strictly in the correct place, but yesterday I spotted a Squirrel running across the road, into our garden. It was not a Red, but a Grey! It is a long time since I have seen a Grey actually in the village. Probably a young one that has been pushed out by its parents and is looking for a new place to call home.
