Adult elephants respond more strongly to calls addressed to them than others
African elephants use unique vocalizations as personal names according to a new study

Unique vocalizations are low-pitched rumbles used for individual identification and communication
In a groundbreaking discovery, a new study suggests that African elephants use unique vocalizations, similar to personal names, to communicate with each other in the wild. The research was conducted by scientists from Colorado State University and Cornell University and published in the journal Nature Ecology & Evolution.
The team analyzed hundreds of elephant calls recorded at Amboseli National Park and Samburu and Buffalo Springs National Reserves in Kenya. They used machine learning algorithms to identify distinct vocalizations that were used consistently by individual elephants. These unique sounds, which are primarily low-pitched rumbles, may function as names for the elephants.
The researchers found that adult elephants responded more strongly to playbacks of calls originally addressed to them than to calls from the same caller addressed to other elephants. This suggests that these vocalizations serve as a means of individual identification and communication among African elephant populations.
This discovery challenges our understanding of animal communication and highlights the remarkable cognitive abilities of African elephants. The researchers believe that this ability to use unique vocalizations as names may be linked to their advanced social structures, complex family relationships, and long-term memory capabilities.
The study also raises questions about how other animals communicate using individualized sounds or signals. Further research in this area could shed new light on the evolution of language and communication systems in various species.

The article discusses a study that suggests wild elephants may use distinctive, rumbling sounds as individual names. The author quotes Mickey Pardo, a biologist at Cornell University, who wonders if elephants might have names like humans do. However, the author's statements about elephants having names are editorializing and not based on facts from the study itself. The study only found that their model was able to identify the correct elephant recipient of a call 27.5% of the time, which is not strong enough evidence to conclude that elephants have names.
He wondered if elephants, which are known to be vocal mimics, might do something similar.
The idea from the outset of this project was to try to figure out if elephants have names.
African elephants may use individualized calls that resemble personal names to address each other, according to a new study.
Elephants respond more strongly to a call that is originally addressed to them than to one from the same caller addressed to someone else.
Adult females were classified more correctly than calls by juveniles, suggesting that adult females may use names more in their calls because the behavior takes years to develop.
Accuracy
Adult females are more likely to use names in their calls because the behavior takes years to develop.
