These squirrels can be seen all around campus. I may see on average at least 10-15 squirrels per day without trying to spot them. This squirrel particularly appears to be the Fox Squirrel, one of Texas’ most common squirrels. One important aspect of the Fox Squirrel is its bushy tail that can be used to keep warm, to give itself balance when running, or to open up and act as a parachute should it fall. Personally, I am not the biggest fan of squirrels just because I am afraid it will attack me if it thinks I am trying to harm it or steal its food. But I also learned observations of the tail can determine its mood. Quick, fast jerks of the tail mean the squirrel is agitated or upset, so if you spot that tail you should probably take another path!
