This makes me love bats even more, which is good, because a friend and I recently took a trip to Salem, and I now own a pair of black leather hightops with both orange bat wings and spiderwebs on them.

Basically, this tweet was posted by a bat biologist who says high-speed film shows that bats crash into each other *all the time*.
