The brand new bird bath might serve as a skating rink this morning.  That is a solid brick of ice!!  A low of twenty-one degrees last night!!  I speculate the Mealworms I delivered quickly became icicles.  However, at 9:05 the Bluebirds were at their dinner table!!

Postscript, Tues. Nov. 27, 2012, 9:30 AM: The Bluebirds were at their feeder seconds after I provided mealworms.
