They do have a "touch of grey", but if you don't know, you might not even notice! What is noticeable is, the tail which is much thicker in winter, and those cute ear tufts, are much thinner or vanish almost completely during the summer! I do keep my camera (at least the small one) with me nowadays at work, but usually they are gone by the time I'm ready to make a photo. But I don't give up, when my short holiday is over, I'll keep on trying!That's interesting. But they change fur color anyway a bit?
Did you see, one of the articles of Looduskalender is about squirrels? I can't yet read it, it's only Estonian yet. I have to wait for Liis' translation.
