Hotlanta Nights and the Bees are starting to Beard!

With slatted racks, screened bottom boards, and propping the hive tops, my hives are about as ventilated as I can accomplish. But as the Atlanta nights get hotter, so does the interior of the beehive. You can see the beard on Bermuda (left in first picture), Mellona (the tall hive). Even Proteus with its mixed up configuration has a beard beginning.

It entertains me to see that the small swarm nuc has its own version of a beard! Of course, that nuc doesn't have a screened bottom board, a slatted rack, nor is the top propped, so even though it is the smallest of my bee colonies, it is probably the hottest temperature-wise.
