Do you know the difference between a critter and a varmint? In my yard, I have a large population of brown squirrels. They are frequent visitors like the one pictured. These guys are really cute, and I love watching their antics as they scamper among my trees, and around my yard. But as delightful as they may be, they are truly varmints. I say that because they gnaw on things they aren't supposed to. They like to chew on the corners of my gazebo, and I've caught them red-handed gnawing on the siding near the eaves of my house, while creating a hole into the attic. The brown squirrels and I have an ongoing dialogue about their behavior, but they are a rebellious group of varmints.
On the other hand, the grey squirrels come in fewer numbers. They are wonderful critters, that make excellent friends to share my yard with.
I only wish I could turn those varmint brown squirrels into critters:-)
