Human voices cause considerably more fear in wild mammals than the sound of lions, a study in South Africa has found.
Researchers concealed speakers near water holes in Kruger National Park and broadcast human conversations at a normal volume. Surprisingly, approximately 95% of the animals reacted with extreme fear, fleeing the area rapidly. In contrast, the sounds of snarling and growling lions prompted notably less alarm.
The selected human speech in the experiment included commonly spoken local languages. Notably, during the study, some elephants, upon hearing the calls of big cats, exhibited confrontational behavior toward the source of the sounds.
These findings indicate that various animals, encompassing species like antelopes, elephants, giraffes, leopards, and warthogs, have learned to associate human presence with extreme danger. This has stemmed from hunting, firearms, and the use of dogs in capturing them.
The fear observed extends beyond Kruger National Park, reflecting a global pattern. Wildlife tend to fear humans more than any other predator, as outlined in the study.
This presents a significant challenge for areas reliant on wildlife tourism. As the very human visitors they aim to attract unintentionally deter the animals they wish to showcase.
Dr. Liana Zanette, one of the authors, explained to the BBC that their study delves into the “ecology of fear,” a concept that explores how interactions between predators and prey influence their surrounding ecosystems.

The Underlying Message
The underlying message of this article is that the presence of humans and the sounds of human voices evoke more fear in wild mammals than the natural sounds of lions. Lions being a top-tier predator in the animal kingdom. This fear has developed due to the historical association of human presence with hunting, firearms, and other threats to these animals. The study reveals that this phenomenon extends beyond a specific location (Kruger National Park) and is a global pattern. This creates challenges for wildlife tourism by unintentionally deterring the very animals tourists come to see. The concept of the “ecology of fear” is introduced to highlight the complex interactions between predators and prey in their natural environments.
In conclusion, the results of the study have shed light on a fascinating and concerning aspect of the natural world. The discovery that human voices elicit considerably more fear in wild mammals than the iconic sounds of lions underscores the profound impact of human presence on wildlife and the environment. These findings reveal a stark reality: many animals have learned to associate humans with danger. This is due to historical threats like hunting, firearms, and the use of dogs.
