The Garden's Buzzing!

Interestingly two colonies have stopped taking syrup
and two are still sipping and storing.  Now the interesting part
is that the two which have stopped feeding have mouse nests
in the top of their hives but the two which are still feeding have no mice.
QB assumes that mice only dare enter if the colony is clustering.  Then
the mice can sneak in because there will be no guards at the entrance. 
Last night we had the heaviest frost of the season.
Almost all the flowers died overnight except for a few cosmos, nasturtiums
and rudbeckia.  And yet the garden is buzzing today.  The sun is bright and
still has some warmth in it.
I think these black northern bees (Apis mellifera mellifera) are the toughest of all
the species.
