One of my hives swarmed two days ago and I managed to capture it. This afternoon it swarmed again and gathered on a branch about 75 feet away, too high to capture. About 1/2 hour after they seemed to have settled down I noticed many of the bees leaving the cluster and milling around. Then a bit later I looked at the original hive and it looked like it was swarming again, it looked like a huge orientation flight, many bees milling around and clustering on the front of the hive. When I went to look at the branch, all of the bees were gone. As I write this, (I can see the hives out of the window) nearly all of the bees have entered the hive. ???
