I opened one of the hives today to replace a feeder, and heard a strange sound. Not the usual buzzing, but something more like clicking. Someone described it as a crisp dollar bill being crumpled, but I’d describe it as a geiger counter on the other side of the room (OK, maybe you haven’t heard one of those). A bit of googling showed I shouldn’t be alarmed, and it was probably bees chewing the wood, or building out wax. Since I’ve had my head in a lot of bee hives and never heard this before, I’m puzzled, but I’d go with the chewing wood theory.
Play the video and tell me what you think it is in the comments. And pardon the blurry video – it’s the sound you should be paying attention to.
