Chipmunk on the Rock Wall

We are in the process of building a rock wall along the side of our house that will eventually curve around to the back of our house and become our deck floor for our patio. Right now the chipmunks, squirrels and various birds are all enjoying searching all its nooks and crannies for sunflower seeds and peanuts each day. They are a hoot to watch and we can lose hours watching them if we have nothing pressing to do.
