1. To study sensorimotor behaviour in wild animals, it is necessary to
synchronously record the sensory inputs available to the animal, and its
movements. To do this, we have developed a biologging device that can
record the primary sensory information and the associated movements during
foraging and navigating in echolocating bats. 2. This 2.6 -gram tag
records the sonar calls and echoes from an ultrasonic microphone, while
simultaneously sampling fine-scale movement in three dimensions from
wideband accelerometers and magnetometers. In this study, we tested the
tag on an European noctula (Nyctalus noctula) during target approaches and
on four big brown bats (Eptesicus fuscus) during prey interception in a
flight room. 3. We show that the tag records both the outgoing calls and
echoes returning from objects at biologically relevant distances. Inertial
sensor data enables the detection of behavioural events such as flying,
turning, and resting. In addition, individual wing-beats can be tracked
and synchronized to the bat’s sound emissions to study the coordination of
different motor events. 4. By recording the primary acoustic flow of bats
concomitant with associated behaviours on a very fine time-scale, this
type of biologging method will foster a deeper understanding of how
sensory inputs guide feeding behaviours in the wild.
Eptesicus_fuscus_prey_capturing_flight_room_experiment_2Data collected on
Eptesicus fuscus in a large flight room at the Johns Hopkins University.
The bat were trained to fly across a flight room and catch tethered
mealworms. The echolocation signals and the echoes were recorded from an
on-board acoustic tag. The tag recorded with a sampling rate of 187.5
