Name a famous elephant . Babar , perhaps ? Or Dumbo ? Memorable though these monikers may be to humans , they sound nothing like the nameselephantsgive each other . If you ’re an elephant , your name is something more like a low , rumbling sound , scientists say .
In a newpaperpublished Aug. 23 on the preprint waiter BioRxiv , researchers found that African savannah elephant ( Loxodonta africana ) made vocalization specific to individuals in their social radical — and that the recipients responded accordingly . In short , elephants come out to have names for one another .
African elephants (Loxodonta africana) in Amboseli National Park, Kenya, appear to have names for each other.
This makes them the first non - human animals to address each other in a manner that does not imitate the pass receiver ’s own call , asdolphinsandparrotsdo . And while other animals do produce what are known as " referential calls " in orderliness to name objects just as predators or food , those call arebelieved to be instinctiveand do not require societal learning .

In the fresh bailiwick , the team memorialize 527 elephant calls in the greater Samburu ecosystem in northern Kenya and 98 calls in the Amboseli National Park in southern Kenya . The researchers then identified rumbles specific to 119 individuals by distinguish which member of group of distaff elephant and their offspring were separated from the herd at the prison term of each vocalization or approached when the call was made .
Using a computer example , the researchers correctly identified the recipient of 20.3 % of the 625 recorded calls .
This marks a step forward in understanding how these highly levelheaded animals communicate .
" There ’s a contact rumble , there ’s an anti - vulture rumble , there ’s a salutation rumble . If you front at a spectrogram , they all front almost exactly the same , or exactly the same,“Caitlin O’Connell - Rodwell , an elephant life scientist at Harvard University Medical School who was not involved in the subject , distinguish Live Science . " That ’s why AI has been exciting . It allows us to really enter out what the elephant are honing in on . "

As it turned out , the calls were not generic sound aimed at , for example , young elephants or mothers . They were distinguishable to the telephone receiver . Even calls from unlike callers to the same receiver were alike — though the formula was less obvious than it was between a single caller and pass catcher . This may be because rumbles encode multiple content simultaneously , so the reckoner mannikin may not have been able-bodied to pick out the " name " used in each call , the authors wrote in the study .
" It just highlights the complexity of what ’s go on , " O’Connell - Rodwell said . " And we ’re not skilled enough at what those measurements should be to figure out what ’s going on . "
The research worker also found that elephant react more strongly to recordings of calls to begin with addressed to them than to calls addressed to other elephant , further sustain their finding .
" The actual note value of this newspaper publisher is that it exhibit how elephant are navigating through a turgid landscape and can still keep in touch with specific mortal , " O’Connell - Rodwell said . " It allow for them to diffuse out much further and still have very close tab on person , not just the group . It ’s not just like , I ’m send out out a ping . Somebody else is sending out a Ping River . It ’s much more sophisticated than that . "
