Short lead events are time locked well to sonar vocal onsets. Data in A–C are from three different randomly selected sites in three different bats and comprise all of the SLE data from single sessions. The short lead event data were collected while bats used echolocation to track a real oscillating target swinging toward and away from the bat. Top panels are sonar call duration versus short lead event times showing the uniform occurrence of event times with sonar call duration. Bottom row show histograms of the number of events at each time showing the precision of short lead events. Time bins are 0.25 ms. Values shown in bottom row represent the number of sonar calls used to construct each plot. Dots at the top of the ordinate, in the bottom row, draw attention to the different range of counts.
