I received an email last night from Kelly at Fountain Rock Park informing me that the observation hive had thrown a small swarm and that it was now on the ground next to a walkway by the Nature Center. She had marked the spot to keep pedestrians away. I went there early this morning to remove it.
See this award-winning video of the undertaking complete with video of bees marching into the box: http://youtu.be/OAGIpN2O-c0
Swarms really are ready to draw comb. Notice in the video of photo of the comb they started drawing in the dirt and on the blacktop!
Not sure if the queen is in there, though. Will put some foundation in and start feeding 1:1.
