The squirrels in our backyard are so well-fed that they get easily bored. Yesterday I saw a squirrel sleeping on my deck railing. I watched him for a few minutes before he got up and hung down off the rail to take a drink from the bird bath (AKA wildlife watering trough). Then, he jumped down to the ground and attacked a stick, rolling around the ground playing with it for a few minutes before coming to the sliding glass door and looking in at me, begging for a peanut. I obliged and he ran up the tree.
Today the same squirrel and the rabbit who lives in our shade garden were out back playing together. The rabbit would hop up high, and the squirrel would do the same, then they did this little dance of hopping around, taking turns chasing each other. After a few minutes the squirrel got bored and went back to the deck rail for a nap.
I had never seen this kind of animal behavior before in my life. It was damn cute.
