For much of the winter, when the weather isn't absolutely intolerable, little red squirrels run back and forth along an obstacle course from our backyard to our neighbors. They begin their trek in a large tree on the far side of our neighbor's yard. After scrambling down the huge tree, they bound in and out of the snow on the ground, run up into our neighbor's tree closest to our house, then tumble down onto our fence with acrobatic ease and hop over little snow hills they create along the top of our fence. From our fence they precariously climb onto a branch barely hanging low enough for them to do so, scramble around the tree in our yard, then run along another branch to hop onto a different part of the fence. Eventually they disappear into the backyard of the neighbor across from the alley way to harvest pine cones from an evergreen tree. Either that or pilfering easily obtained bird food from the neighbor's hanging feeders. The squirrels then bravely retrace their steps back to their drey with goodies in tow.
