Some people would argue that bats are anything but cute. But that is simply because they have never met a bat. Some bats are very adorable. A study in 2016 analyzed a strange and cute mannerism observed in many bats: head waggling. A waggle is when the bat turns its head side to side while looking at something.
“It’s an adorable behavior, and I was curious about the purpose,” said Melville J. Wohlgemuth, a postdoctoral fellow in the Krieger School of Arts and Sciences’ Department of Psychological and Brain Sciences. “I wanted to know when bats were doing this and why. It seemed to occur as bats were targeting prey, and that turns out to be the case.”
