Fig. 2. Diagram of the flight room (6.4 mx7.3 mx2.5 m) and the experimental arrangement for the bat attack experiments. The gray box represents the calibration space for the high-speed video cameras (2.2 mx1.9 mx1.6 m). The dashed lines illustrate the two typical flight path types for the bat attacks (direct approach, blue line; indirect approach, red line).
