Abstract

Studies of bat echolocation and flight typically involve microphone array recordings from the ground, sometimes synchronized with video recordings. When multiple bats interact, it is often a challenge to assign a given call to the vocalizing bat. We have designed a lightweight, inexpensive device to display bat-tagged echolocation events using a head-mounted light-emitting diode (LED) that flashes when an onboard microphone detects a high-amplitude ultrasonic pulse. We describe the circuit and demonstrate its functionality in flight on the head of a big brown bat.
