African wild elephants address each other through sounds, and they make distinct rumbling noises to address another elephant, and the latter knows exactly when its companion is referring to it.
African Wild Elephants Make Rumbling Sounds Akin to Name
According to Mickey Pardo, a biologist at Cornell University, dolphins will mimic someone else's distinctive whistle to draw attention, essentially addressing them by name. Given that elephants are known to mimic vocalizations, he wondered whether they may act similarly.
In a new study, Pardo and colleagues tried to figure out whether elephants have names. The team examined 469 recordings of rumbling calls that African wild elephants had exchanged with one another in Kenya's Samburu and Buffalo Springs National Reserves, as well as in Amboseli National Park, between 1986 and 2022. For each call that was recorded, the researchers were able to identify the elephant that was making the call and, depending on the situation, the elephant that was being addressed.
Just as people don't call each other by name every time they speak to one another, it would not be anticipated that elephants have names for each other.
To determine whether the rumbles had any identifying information, or more precisely, a "name," that their computer model might learn to utilize to forecast the recipient of a call, they also employed machine learning.
What they discovered is that, in comparison to a control analysis where it was fed random data, their model performed far better, correctly identifying the correct elephant recipient of the call 27.5% of the time.
It was discovered that the elephants typically appeared to be able to discern when a rumbling message was intended for them, implying that it might have carried a name. They moved closer to the speakers after hearing those calls. They also made more answer calls and responded vocally faster.
According to Pardo, the elephants had a significantly stronger average response to call replays that were directed at them, as opposed to call replays from the same caller that were intended for another individual.
Karl Berg, a biologist at the University of Texas Rio Grande Valley, said the results were "very convincing." He believes that elephants have some labels on each other but is unsure if they are nicknames or names or where they come from.
Elephants Communicate With Gestures And Sounds
Elephants are like humans when it comes to communication. In another study by Vesta Eleuteri of the University of Vienna in Austria, they observed how elephants interact and noticed that they make certain sounds and gestures.
Elephants possess "multi-component" or "multimodal" communication. Frequently, they would flap their ears forward and rumble. She saw a consistent pattern: the elephants would rumble before fluttering their ears. Another variation involved shouting and rubbing their tail against the receiver or rumbling and extending their ears forward. She claimed that there were various combinations.
Eleuteri also affirmed that certain elephants are more gregarious than others. According to her, Doma, a savannah elephant named Doma, is his kind's favorite.
Doma was well-regarded by all, and when the other elephants got into difficulties, they supposedly went to him for assistance. When they brought Doma back together with the other male and female elephants, both responded in kind. They display affection and submission to Doma.
