Once while in my treestand I spotted a chipmunk searching for food in the leaves. He would pop his head out and look to see all is well I would just move my foot and he would pick up on the motion and would duck back under a hole between rocks for protection against Hawks I guess. After about a minute or two he would pop his head out and again I would shuffle my foot, This went on for about 20 minutes untill I finally got tired of the game. He kept me company for hours.
