That made me wonder how bats see water surfaces. Though I suppose not seeing them is less of a problem since they're not vertical :P

- SeanDav 9y agoThis is a good point. Perhaps the sound penetrates a distance into the water and you get scattering, returning a small signal.
- maxxxxx 9y agoReal life water surfaces are probably not as smooth as glass windows. Just a guess.
- ethomson 9y agoThe post explains this: they don't. Standing water exhibits the same behavior as reflectiveless flat surfaces. When they fly over a space and "see" nothing beneath them, they interpret this emptiness as a flat, smooth body of water. Thus the only real problem here is that for flat horizontal surfaces that aren't water, the bats will try to drink from them.
