The Coyotes of Yellowstone National Park are nothing if not focused. Once they are on a mission, they are not deterred. Concentration on the task at hand helps them survive, especially in the harsh conditions of winter in Yellowstone. The meadow voles that are a favorite target of Coyotes there burrow in the snow. The Coyotes hear their movements as they travel through their snow tunnels by intense concentration that allows for the precise moment to pounce.
