I have been fortunate to hear this quite frequently. We keep our queen cages in very close proximity just before shipping and we hear them piping almost every time we harvest queens. You're right, close proximity seems to be the trigger, when we seperate them by about 5-6 feet it stops. We have tried isolating the 'piper' but it is impossible, as you get close and disturb them the piping stops. ***************************************** The Bee Works, 5 Edith Drive, R R # 2.
