Well, bats do estimate the location of the prey targets that they are
attempting to capture, so it's not simply a rock falling. The mechanisms
of this localization seem to involve measurement of range by echo-delay,
azimuth by comparison of the signals at the two ears, and elevation by
comparison of the target spectrum with a continuum of spectral
characteristics. The bat also estimates target velocity and acceleration
from those data, and predicts the target movement over time as part of
an internal world model.
