(PLOS) A Johns Hopkins University researcher noticed the bats he works with cocked their heads to the side, just like his pet pug. As the article publishing in open-access journal PLOS Biology details, using high-tech recording devices, Wohlgemuth determined that a bat's fetching head waggles and ear wiggles sync with the animal's sonar vocalizations to help it hunt. The finding demonstrates how movement in bats can enhance signals used by senses like sight and hearing.
