Thanks for the comments . You are correct Woddie that ear tufts are absent in Greys but Red Squirrels moult twice a year and in the summer the ear tufts are either small or absent hope that helps.
We have a squirrel in a nearby tree and that's very ginger though. Many people think it's a red, but it is a grey. So it wasn't a joke I poking at your picture, which is very nice of course.
Similarly, about 10 years ago, we had a white blackbird, other than its tail, on the local playing fields. Weird or what?
Thanks for the coments Simon. Yes Woody there can be quite a bit of colour variarions in both species - I have not spotted any of the black variation yet - dont know what areas of the country that are in. Probably never get as far north as here as the greys have never got here yet.
