I spotted a white Grey Squirrel down on the ground in lovely sunshine the other day.
However I had the wrong lens with me.
So I went back today, with a long lens, on a damp, gloomy day and he was staying way up high in a big Oak tree.
The other one looked even whiter than this one, and one of the regular doggie walkers said she thought that there was more than just one white one.
I will have to wait for another sunny day.
