I discovered this midden (a mammal's food cache or food debris) while on a walk on the Turtle Flambeau Flowage in Iron County. Tracks on either side revealed that a red squirrel ate breakfast on this downed red pine. Weighing in at less than a pound, it is remarkable that these creatures stay active during Wisconsin winters. Red squirrels are solitary for much of the year, but now may stay warm by huddling in tree cavities with family and friends.
