This squirrel is suspicious as it saw me behind the window. It has changed its grey winter fur for a brown summer fur. I saw another squirrel which still has grey trousers even if its coat was brown. It escaped my camera.
How wonderful to see the cousins of the squirrels I visit everyday in the park! I was fascinated to read that they change colors, and your description of "grey pants and a brown coat" make me think of the way Beatrix Potter painted clothes on her animal characters!
