a–e Sequential scanning (using the sonar beam axis) of S− and S+ in five trials in which the bat first inspects S− and then subsequently hits S+ with vocalizations indicated by squares. The beam axis was manually assigned to either S+ or S− or no target (NT) for each vocalization by examining the relative tracking direction, duration and pulse interval. Time zero corresponds to the last vocalization directed at S− before the bat shifted its beam axis away from or beyond S−
