A Experimental setup. (a) Two feeders with landing platforms and RFID antennas. (b) A—juice pump, B—feeding tube, C—RFID antenna. The bottle on the side collected juice spillover, allowing us to quantify drinking. B The experimental procedure—phase 1: both of the feeders reward with p(reward) = 1. Phase 2: the bats were divided between a stable and a volatile environment. The rewarding feeder (p(reward) = 0.8) and the less rewarding feeder (p(reward) = 0.2) changed either every hour (volatile environment) or after 2 nights (stable environment)
