Event Abstract Back to Event The role of wing airflow sensors in bat flight control under wind gust conditions Ben Falk1*, Delphia Varadarajan1 and Cynthia F. Moss1 1 University of Maryland, College Park, United States Insectivorous bats rely on echolocation and other sensory modalities to perform complex flight behaviors as they track flying prey and maneuver around obstacles. Microscopic hairs on the bat’s wing contribute sensory information to adaptive flight behaviors. The wing hairs are hypothesized to provide the flying bat with sensory information about air currents across the wing membrane. Neurophysiological studies have shown that bat wing hairs are directionally sensitive to airflow, and behavioral studies have shown that wing hair removal results in a decrease in the bat’s flight maneuverability (Sterbing-D’Angelo et al., PNAS, 2011). Here we report data from a behavioral study in which bats encountered gusts of wind as they performed an obstacle avoidance and prey-capture task. Echolocation signals, flight trajectories and wing kinematic data in baseline trials were compared with data in experimental trials, in which hairs were removed from the trailing and leading edges of the bat wing. Wind gusts were introduced randomly from different directions as the bat maneuvered through a narrow opening in a net to gain access to a tethered insect one meter beyond the opening. The effects of air turbulence on the bat’s flight maneuverability and echolocation behavior were quantified with high-speed video and sound recordings. By studying the effects of air turbulence on wingbeat kinematics, flight path, and echolocation behavior in bats with and without wing hairs, we hope to learn more about the mechanisms by which mammals and other organisms process sensory information to adapt their behaviors.
