Nice one Mike - so do you think it was two swarms then if there were two queens within
The only time I've heard piping before is when I've received two or more queens in the post, so to actually hear it after collecting a swarm is wonderful and a rare treat.
When I arrived about 11:30 AM Jim lead me to see the swarm on the climbing frame, on route we passed under a massive sycamore tree and there was hundreds of bees circling around one of the branches forming the second cluster which he didn't notice as they were just hanging there quietly. The climbing frame is about 40 feet away from his hives over several bushes and a fence and the cluster in the tree was another 30 or so feet further on.
Heres where I can only speculate.
I was taught the lower the swarm the better the chances of a mated queen, I'm sure some may disagree but if that saying is true then I would guess the swarm on the climbing frame is either a princess or I think the original queen and the other cluster much higher up at about 20 foot or so in the tree is definitely a virgin queen with her cast. The hive was looking pretty full when Jim last inspected it and it hasn't thrown a swarm recently. I can't give a reasonable answer why if it is mother and daughter they swarmed on the same day as this doesn't fit as the weather down here has been pretty good for the last couple of weeks, so two daughters in two casts seems more likely but then why did they combine and where is the original unclipped queen.
The cluster in the tree were just hanging there, the cluster on the climbing frame were fanning like mad when I first saw them which is a good sign the original queen is with them. All I can say for sure is the piping I heard was definitely of two very different pitches and every now and then at the same time before I got the camcorder out but I can still tell the two apart from listening to them in a video.
The other thing is I'm sure I spotted one of the queens, as you can see the markings on the bees is a very nice crisp tiger strip pattern but I saw a longer deep tan or ginger and black striped abdomen briefly when they dropped into the tray as I collected a large lump of the cluster.
I think the original queen and one of her daughters swarmed on the same day. So a prime and cast swarm and they formed the two clusters before combining in to one very good sized swarm on the climbing frame.
Hands up who tilted their head when watching the first part of the video?
