Israeli scientists conducted a study, during which they found out that bats talk to each other, emitting up to 15,000 types of signals.
Experts from Tel Aviv decided to find out what the bats communicate about. After all, a person, seeing these animals, hears only a squeak and squeal, and they probably report a danger or try to drive him away.
The experiment proceeded as follows: the animals were placed in an acoustic chamber and placed in a cave. The study lasted 75 days. All this time, scientists have been recording and trying to distinguish the sounds they hear.
The results surprised scientists - it turned out that bats do more than just inform others about danger or food. They even have different intonations for "friends" and "enemies." Animals can argue for no reason, or over a comfortable overnight stay.
It should be noted that in Voronezh, volunteers collect money for a refrigerator for bats. The problem is global warming, due to which there are sudden changes in the weather, as a result of which animals cannot hibernate and get food. It is important that not the food will be placed in the refrigerator, but the bats themselves, in special sleeping bags.
