Researchers argue that bat caves are noisy for a reason. They have revealed that these nocturnal creatures have plenty of reasons to argue about, using a particular way of communication through noises. Based on the data unveiled in the new research, scientists have discovered that bats use a unique method of communicating.
A team of researchers has analyzed 15,000 sounds emitted by 22 Egyptian bats. Scientists believe that these noises transmit information, carrying a particular meaning including the context of the chatter, the identity of the listener and the identity of the talker. Yossi Yovel, who is a neuroecologist at Tel Aviv University, noted that the sounds emitted by bats are no longer believed to be void of meaning. They have finally unveiled that bats use sounds like a way of communicating.
Apparently, bats fight over food, sleeping positions, or mating. Yovel also argued that they have found out that a bat which overhears the quarrel between other two bats it can establish the identity of the two bats, which one is shouted at and even what the context of screaming is. They can understand whether the other two bats are fighting about mating, food, or sleeping positions.
The team of scientists could identify some sounds which were thought to indicate ways of greeting each other, and they had even distinguished between greetings when it comes to an enemy and greetings used among friends. This is indeed spectacular. Who would have ever thought that we will decode the language of bats?
As far as we know, we are not the only social species in the world. Bats are social animals too. They can live up to 20 or even 30 years. They usually settle in large colonies. Bats use screams or vocalizations to communicate with each other. Probably, their language may be similar to the one used by monkeys or dolphins. This study proved that complex vocal communication might gradually develop.
Yovel together with the members of his team have developed a bat cave in their laboratory, and they have monitored them for 75 days, 24/24, using microphones and video cameras. This was the first study used such an extended amount of data demonstrating that bats’ vocalizations contain several meaningful messages for their peers.
