This is the tiniest squirrel I have seen here.....there are now four who routinely show up, but this is not one of them.  This may be the one I photographed a while back and it looked like it had mange.  He looks really scrawny compared to the others, but doesn't appear to have mange any longer.  
He showed up while I was exercising on Zoom with our group and was watching me!  He looked like he was saying, "What on earth is she doing?".....Mondays I feel like that too......what on earth am I doing?  BUT, some exercise is better than none at all, right?
Had to come back and add a photo from later in the day....big storm front came through bringing rain, but the clouds were terrific!
