Fig. 7. The inner window (i.e. duration of emitted pulse recalculated to distance;
blue line), the bat's distances to the net (green line), the mealworm (black
line), and the landmark, if present (pink line). Time 0 is when the bat
interacts with the net (fly through or crash). The red arrows indicate the
point in time where overlap between the inner window and the net echo starts
(blue and green lines cross and blue line is above the green line). (A,B) The
bat flew through the hole and in (A) experienced an overlap 200 ms before it
flew through the hole (see red arrow), but in (B) produced a high rate sound
group and overlap between the pulse and the net echo did not occur until 90 ms
before the bat flew through the hole (red arrow). (C,D) The bat crashed into
the net. In (C) the bat produced a high rate sound group and the overlap
occurred around 50 ms before the bat crashed, whereas in (D) the bat did not
produce this high rate sound group and experienced an overlap between pulse
and net echoes 190 ms before crashing into the net.
