Recent research has shown that bats change their voices to mimic the buzzing of stinging flies and butterflies in order to avoid invading birds.
According to media reports, although the art of intimidating or avoiding the enemy by changing its voice or form has so far appeared in insects, but for the first time this feature has been discovered in a mammal. Danilorioso, a scientist at the University of Naples Federico II in Italy, heard the peacock's unique buzz many years ago while doing his PhD.
After research since then, they have come to the conclusion that bats do this to protect themselves from their enemies, the owls.
