different flight paths of a bat and 
moths.
These 
paths were experimentally obtained from video recordings in the flight chamber, using the same bat individual and different moth individuals. The top panels represent the flight paths of a bat and 
moths in the horizontal plane of the chamber, and the middle and bottom panels represent the time series data for 
and 
. Note that the bat captured the first moth but not the second moth, during each session. In the top panels, the flight paths of the bat, the first moth, and the second moth are given by black, pink, and light blue lines, respectively. In the middle and bottom panels, dotted lines describe 
and
