Bats change sounds to scare away hungry owls

Rome, Italy: For the first time, we have learned that bats mimic the sting of flies or butterflies by changing their voice to avoid invading birds.

Although the art of intimidating or avoiding the enemy by changing its voice or form has so far been found only in insects, but for the first time this feature has been discovered in a case.

Danilo Reuso, a scientist at the University of Naples Federico II in Italy, heard the strange buzzing of a bat several years ago while doing his PhD. Whenever she came out she would make a noise like a fly. Now they have taken a closer look at this phenomenon.
They listened to recordings of a famous rat-eared beetle (Mayotis myotis) that resembled bees and butterflies. When the sound of bats hitting a potato came back, the sound got closer to the bees.

In the next stage, they made two different sounds to two types of owls, numbering about 16. Half of these animals were in direct contact with the environment and the other eight were kept in the laboratory. Bringing the speaker closer, four different sounds were heard to each owl. First, the original sound of a bat, second, in which it was mimicking bees, third, the sound of a European hornet, and fourth, the sound of a bee.

Hearing the three kinds of buzzing, all the owls backed away at once and as soon as they heard the real sound of bats, they approached the speaker.

The reaction of some of the owls was also different and they were very scared to hear the buzzing. In the past they may have been bitten by a fly or a stinging insect or some such incident may be fresh in their memory.

This research raises the question of why, while one type of bat has learned this tactic to protect itself, other species of bats have not adopted it. Now experts are searching for the.
