A recent study suggests that wild elephants might use unique sounds, similar to names, to address each other. The study, published in Nature Ecology & Evolution, was inspired by previous research on bottlenose dolphins, which use signature whistles to call each other by name.
Dr. Mickey Pardo, a biologist at Cornell University, led the research. Pardo wondered if elephants, known for their vocal mimicry, also used specific sounds to address individuals. The study aimed to determine if elephants have names they call each other, not the names given by researchers.
Elephants make a variety of low-frequency rumbling noises in different situations, from greeting family members to staying in touch over long distances. Pardo and his team analysed recordings of 469 rumbling calls made by wild African elephants in Kenya’s Amboseli National Park and Samburu and Buffalo Springs National Reserves, spanning from 1986 to 2022. They used machine learning to identify patterns in the rumbles that might indicate a name.
Their model successfully identified the intended recipient of a call 27.5% of the time, much better than chance, suggesting that the calls contained identifying information. Further field experiments involved playing recordings of calls to individual elephants. The elephants reacted more quickly and strongly to calls directed at them, implying recognition of their “names.”
The study’s findings imply that elephants, like humans, dolphins, and parrots, use unique sounds to address each other, reflecting their high intelligence and complex social structures. Understanding these communication patterns could improve conservation efforts, as recognising individual elephants’ needs and social connections can inform better protection strategies.
There are several public health implications of this discovery about elephant communication:
Conservation and Ecosystem Health: Understanding elephant social structures and communication can enhance conservation efforts, which in turn supports the health of ecosystems. Elephants play a critical role in maintaining the balance of their habitats. Healthy ecosystems contribute to human well-being by supporting biodiversity, providing clean air and water, and offering resources for medicine and food.
Human-Elephant Conflict: Improved knowledge of elephant behaviour and social networks can help mitigate human-elephant conflicts. By better understanding elephant movements and social dynamics, strategies can be developed to reduce conflicts, protecting both human communities and elephant populations. This can prevent injuries and deaths on both sides and reduce stress and economic loss for local communities.
Mental Health and Well-being: Elephants are keystone species, meaning their health reflects the health of the ecosystem. Protecting and understanding elephants can contribute to the mental well-being of people who live in close proximity to these animals, as well as those involved in conservation work. The stress and trauma from witnessing elephant decline or conflict can be significant.
Cultural and Educational Impact: Elephants are integral to the cultural heritage of many regions. Understanding their complex social behaviours can foster a deeper connection between local populations and wildlife, promoting mental health through a strengthened sense of cultural identity and pride. Educational programs that include these findings can enhance community engagement in conservation efforts.
Overall, the study’s findings underline the importance of conserving elephant populations, which supports broader public health goals related to environmental health, community safety, and mental well-being.
