We probably have more black squirrels here than brown/grey ones. I like the brown ones WAAAAAAAAAAAY better. Not only are they cuter, but they seem to be more calm and far less agressive. They are more friendly too. The brown squirrels in our area are a bit larger than the black ones. The black ones have no shame. They come in our backyard and mate in front of everyone, for the whole world to see. lol I've never seen the brown ones doing this, but why so the black ones have to do it where everyone can see, and WHY did they have to choose our backyard for this? LOL LOL LOL
