I am posting this for a friend with a LARGE feral hive in a tree in his front yard. He has called me for two days saying the bees in this tree are trying (and failing) to swarm. He said yesterday approximately 200 bees swarmed out of the tree and "tornadoed" (his word) around in the air, but never landed anywhere. Then proceeded to go back in. this was 2:00pm. He just called me and told me that they are doing the same thing again today, right now. I put a bait hive out in his yard about a week ago. Any idea what may be going on? He says it isn't orientation flights, but I haven't seen the activity for myself so I don't know.
