Hawk and Mouse
The leader takes on the role of the hawk. All of the girls become mice. Hawks hunt their prey by sight; if they can see something moving, they will pounce!
While leading the girls on a hike, and with your back to the girls/mice, the hawk flaps their wings and walks quickly along the path, as if you are simply flying from one place to another. At any point the hawk can suddenly stop flapping and turn around. At this point all the mice must freeze. If the hawk catches a mouse moving, that mouse has been "eaten" and that player goes to the back of the group. When the hawk resumes flying, the mice can move again. Their goal is to be as close to the hawk as possible without getting caught moving when the hawk turns around!
