Second Swarm, or 2nd-5th Swarm?

On May 11th, I saw scout bees investigating knot holes on the side of the barn. That happens when a colony either has or is about to swarm. It's a warning—go check the trees and shrubs around the bee yard. They usually cluster somewhere nearby. Here's what I found:

It looks like 4 swarms. More likely, one swarm got separated. I thought they'd eventually combine into one, but they seemed content to stay separate. I believe they parted over some disagreement over a doctrinal issue. I dumped them all into a cardboard box and left a small door open. Within an hour they settled their differences, and the stragglers climbed in the box. They weighed 6 lbs or approximately 21,000 bees. I saw the queen, a big blond.
