Elephants Appear to Match Their Deep Rumbles When Communicating

Scientists have discovered that African savannah elephants can adjust their deep rumbling calls to sound more like those of nearby elephants, offering new clues about how the animals communicate within their families.

Researchers used machine learning to study 902 recordings of wild female elephants collected over four decades in Kenya’s Amboseli National Park.

Elephants Have Their Own Vocal Conversations

Elephants communicate through a wide range of sounds, including extremely low-frequency rumbles that can travel long distances. Some of these sounds are too low for humans to hear clearly.

Researchers examined recordings from different social situations, including elephants greeting relatives, staying in contact while separated, reassuring calves and coordinating group movements.

Their Voices Became More Similar

When elephants joined the same vocal chorus, researchers found that their rumbles sometimes became acoustically more similar as the chorus continued.

This was particularly noticeable when elephants were reconnecting after being separated, maintaining contact or coordinating what the family should do next.

Machine Learning Helped Separate the Calls

Studying individual elephants in a group chorus is difficult because several animals may be producing overlapping sounds at the same time. Researchers describe this challenge as similar to trying to identify one voice in a crowded room.

Machine learning allowed the team to examine the complex recordings and track patterns within the overlapping rumbles.

A Possible Role in Group Coordination

The findings suggest that vocal convergence may help elephants coordinate activities and maintain social connections. The researchers say the rumbles appear to contain information not only about individual animals but also about what the family group is doing.

Further research will be needed to determine exactly how elephants use these changing vocal patterns and whether similar behaviour occurs in other elephant populations.
