Above:  Flying squirrel in a condo (Eastern White Pine).  A wound started the CODIT process and carpenter ants respected boundaries and built galleries.  Thus controlling the environment inside the tree, to the disadvantage of the decay fungi.  A Pileated Wood Pecker created the cavities going after the ants.  Now a family of flying squirrels have moved in.  For more see "carpenter ants" and follow the link at the bottom on white pine and ants story.
