Say hello Mr. New Squirrel

So after another new face appeared in my window I started thinking whether squirrels see color? And if so do you think squirrels dislike other squirrels based on their color? Do you think squirrels are raceist? I only wonder because it has been battle royal with Mr. Black squirrel and Mr. Grey Squirrel.......Maybe it is because Mr. Grey Squirrel thinks it is unfair that all the opportunities have been passed out to Mr. Black Squirrel and now he is trying to get his share in this unfair world. Sounds like these squirrels are taking on affirmative action........
