There is a very cool thing that happens in this video (aside from all the muzzlepuff licking) that I'm thrilled to have captured. I've noticed that when bats decide to change location, they literally turn on their radar. You can hear Mirabel do this when she raises her head and looks around at 1:35 in the video. Turn up the sound on your computer and listen for a low thrumming sound--that's Mirabel. I don't know if she's echolocating, but she's definitely sending out pulses, and it is most likely to help her orient as she crawls under the towel. Bats. What we don't know about them fills volumes.
Soon, there would be another! Bats seem to come in twos. At least for me!
