I was reading in a bee book about drone congregation areas, and found the subject very facinating. Drone congregation areas are areas where the local drones fly about and await the arrival of new queens to mate with. Somehow new queens know just where to go.
One story I read is about a fella who puts queen phermone on the end of a tall pole, and wanders about until he somehow finds mess of drones. He takes note of the sight. I guess it's kind of hobby of his.
I'd be interested in hearing if anyone has located such congregation areas in their greater bee yard neighborhoods, and what they saw.
