    Bats are awesome!
    Recently read a post by some biologist, who was wondering how bats avoid crashing into each other, when they all leave or return to their narrow caves at the same time. He speculated that they must use their echolocation to evade other bats.
    But his sound recordings didn’t match his theory. So he set up a high speed camera at a bat cave entrance to film them.

    Spoiler

    They crash into each other all the time.

      You can hear bats running into each other while leaving a cave. It’s not super loud, I only noticed it after cupping my hands on my ears.
