I live in Atlanta, Georgia (USA), and have noticed some rather bizarre behavior recently from my bees. I have a couple of hives in the back yard, about 30 feet from the back-of-house sliding glass door, and for a number of mornings off and on I've noticed several hundred bees spread out over the sliding glass door about an hour before dawn. When I turn on the outside light, they become irritated and fly at the light, buzzing loudly. As it gets light, they disperse and either return to the hives or leave to forage. We've had 100+ degree Fahrenheit days here off and on over the course of the last couple of weeks, with very little rain and temperatures only cooling into the low eighties at night. Humidity levels are fairly high, despite the lack of rain. I've provided lots of water to the hives, but am wondering if this behavior indicates that the bees are seeking additional moisture from condensate on the glass door...? This is definitely not swarm behavior, but I've never seen it before. Both colonies have stores, and although both are new package colonies (started in April), populations are good and they've both drawn comb in 1+ full brood chambers. Any ideas? Jeef
