[TheForge] OT: Squirrels and maple sap?

[Bruce Freeman]

   squirrels in my backyard are exhibiting a behavior I hadn't previously
   observed.  I see them hanging on the sides of the trunk and the
   undersides of the branches of my red maple in my backyard.  I can't
   really see what they're doing, but they act as if they're gleaning
   something.  It occurred to me that the sap may be rising.  If they had
   the brains, they could tap the sap for the sugar.  Their teeth are
   certainly up to scoring the bark.  I wonder whether that's what
   they're doing.  I haven't gotten close enough to tell.  Anyone ever
   see behavior like this?
