A fox squirrel buries a black walnut (Juglans nigra) after removing the husk and carrying the nut 460 meters (straight line distance) from the walnut tree. In a study by Stapanian and Smith, each squirrel cached black walnuts from a single source in areas near their den tree (1978), so in this case, the pictured squirrel must have ranged almost half a kilometer from his den to find the walnut tree. Although squirrels are good at finding buried nuts, some nuts will likely remain in the ground and sprout. Like bees unintentionally pollinate plants in return for nectar, squirrels unintentionally propagate the forest in return for a winter food supply.
