25 bytes were separated from the joke, which were repeated by the bat chicks.
People in addition, a few other animal species, such as bats, are known to roam. Published on Thursday in the German Museum of Natural History in Berlin in the study the roaring of bat chicks was analyzed in more detail and compared to the roaring of human babies. A lot of similarities were found between them. This was reported by, among others, the news agency AFP.
Joking is a way in which babies mimic and practice adult speech.
Research group went through 216 recordings of the twinkling of twenty big-wave backflip chicks. Recordings were collected from two different bat communities in Costa Rica and Panama.
The researchers found that the chicks repeat “syllables,” joke rhythmically, and behave similarly to human babies. The sounds were also congruent between different communities, so they are typical of the species.
“Baby babies joke first to be in touch with their guardians, but also when they are completely alone, they seem to be happy to get to know their own voice, and so do our bats,” estimates the animal behavior researcher who conducted the study. Mirjam Knörnschild To AFP.
Bats communicate with each other with ultrasounds, which are so high frequencies that a person cannot hear them. They are also capable of producing sounds at frequencies heard by humans. The sounds sound like a loud twitter.
Joking begins with a bat about three weeks after birth and lasts from seven to ten weeks until the pup becomes independent.
During that period, the chick spends almost a third of her day on the river. Joking lasts an average of about seven minutes, but at its longest, researchers found that one bat chick roamed for up to 43 minutes.
“It’s very special and that’s not what other bat species studied so far do,” commented Krörnschild.
The soundtracks of the chicks were converted into images, and in total more than 55,000 of the “bytes” they produced were collected.
From the large number of bytes, 25 bytes were distinguished, which are clearly different in appearance to the human eye as well.
The bats of the bat did not know all the syllables as soon as they started joking, but like human babies, they learned the syllables as they grew. When they became independent, they did not yet know all the pronunciations correctly but continued to learn.
Already well at a young age, bats learn a six-byte song with which male bats mark their territory and attract females. Krörnschild says the chicks listen to the males and imitate the singing.
All bat chicks learn the song, even though female bats no longer play the song as adults. However, research suggests that learning a song can help them assess the performance of future partners.
In addition to bats and humans, there are only a few other species that know how to river. These include a few bird species, two silkworm species and possibly some dolphin species, as well as milk whales.
