As the weather gets cooler, it becomes a lot more pleasurable to be out in the fresh air, working up a sweat from movement (and not from humidity!).
All of the smaller creatures are busy. I love to watch them go about the hard work of storing up a winter’s worth of food. I once learned that they will bite a nut before tossing it down. The damage to the shell prevents the nut from being able to grow into a tree.
