My bees will occasionally collect sap from Birch trees in the spring.
     This is not usual, since it is not usually available.  I have not seen
     any problem.  After all the work boiling the syrup it would seem a
     waste to use it for bees.  But Maple Syrup is an exotic substance up
     here in the maple free state of Alaska.
