What sound does a queen make that resembles a duck to attract another queen?

The correct answer is the sound known as piping. This sound is made by a queen bee and is characterized by a soft, high-pitched tone that can resemble the sound a duck makes. Piping is particularly important during a situation where multiple queens are present, such as when a new queen is emerging in a colony. The sound serves as a signal to alert other queens of her presence and can potentially deter competition. Understanding this behavior is essential in beekeeping as it indicates moments of transition in the hive, such as swarming or the establishment of a new queen. Other options do not accurately reflect the specific sound made by a queen bee, thus reinforcing the significance of piping in the communication and social structure of bee colonies.
