Abstract:
We present initial results of the study where we used microphones, placed in front of nest boxes, to monitor daily
foraging activity of bumblebees. Sound recordings were analyzed using a custom-made computer algorithm which detects
flight buzzing sounds coming from arrivals or departures of individual bees. In addition, the algorithm distinguishes between
arrivals and departures. We show examples of daily activities for three species (B. pascuorum, B. humilis and B. hypnorum),
each was monitored over the course of one day. This paper presents initial results of a longer study where we plan to
systematically investigate the activities of bumblebees in various circumstances.
