Here's a quick question for some beekeeping experts: I caught a swarm today from a tree in someone's front yard. The swarm was quite small and I suspect that it is a secondary swarm with an unmated queen. When I first approached the swarm, I observed them for a minute or two. I swear that I heard "piping" coming from the swarm. I've never heard a queen pipe before, but I've watched several videos. Is it possible that this was a virgin queen piping from somewhere within the swarm, or was I just imagining it?
