Kill them with cute: The adorable behavior that helps bats catch prey

A Johns Hopkins University (JHU) researcher noticed the bats he works with cocked their heads to the side, just like his pet pug. "It's an adorable behavior, and I was curious about the purpose," said Melville J. Wohlgemuth, a postdoctoral fellow in JHU's 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." Using high-tech recording devices, Wohlgemuth determined that a bat's head waggles and ear wiggles sync with the animal's sonar vocalizations to help it hunt.
