Red Squirrels are cone specialists and create massive debris piles, called middens, in areas where they regularly eat (typically atop a stump, fallen log, or low, broad tree branch). These middens are easy to spot and are often more than a meter in width. In Western Washington, these cone middens are usually created by the Red Squirrel’s cousin, the Douglas Squirrel (T. douglasii).
