Lions, renowned as the apex group-hunting predators, ostensibly inspire the most fear in the animal kingdom.
Despite the formidable nature of lions—including their power, impressive speed, and collaborative hunting tactics—a groundbreaking study has revealed that the various species roaming the African savanna exhibit a greater fear of humans than of these majestic big cats. This intriguing revelation was highlighted by conservation biologist Michael Clinchy from Western University in Canada, who posits that lions, as the largest terrestrial predators that effectively hunt in packs, should naturally evoke the most trepidation among other animals.
“Normally, if you’re a mammal, you’re not going to die of disease or hunger. The thing that actually ends your life is going to be a predator, and the bigger you are, the bigger the predator that finishes you off,” says co-author Michael Clinchy, emphasizing the stark reality that larger prey face higher mortality risks from formidable predators. “Lions are the biggest group-hunting land predator on the planet and thus ought to be the scariest, and so we’re comparing the fear of humans versus lions to find out if humans are scarier than the scariest non-human predator.”
However, in a study involving over 10,000 observations of wildlife reactions, researchers unearthed a striking statistic: an astounding 95% of the animals exhibited a heightened fear response to human-generated sounds compared to the roars of lions. This significant finding contradicts the notion that wildlife would become desensitized to humans in the absence of threats, underscoring a pervasive and instinctual fear of human presence that spans the African landscape.
The dedicated research team from Western University conducted their experiments by playing various sound recordings for animals gathered at waterholes in South Africa’s Greater Kruger National Park. Notably, even in a protected zone renowned for its substantial lion population, animals demonstrated a more pronounced nervous reaction to human sounds, firmly establishing humans as an imminent danger in their eyes.
“We put the camera in a bear box, not because there are bears out in South Africa, but because of the hyenas and leopards that like to chew on them,” explains first author Liana Y Zanette, another conservation biologist affiliated with Western University in Canada. “One night, the lion recording made this elephant so angry that it charged and just smashed the whole thing.”
“I think the pervasiveness of the fear throughout the Savannah mammal community is a real testament to the environmental impact that humans have,” remarks Zanette, emphasizing the far-reaching consequences of human activity. “Not just through habitat loss and climate change and species extinction, which is all important stuff. But just having us out there on that landscape is enough of a danger signal that they respond really strongly. They are scared to death of humans, way more than any other predator.”

**Interview with Conservation Biologist Michael Clinchy on the Study of Wildlife Fear Responses**
**Editor:** Today, we’re fortunate to have with us Michael Clinchy, a conservation biologist from Western University in Canada, who co-authored a fascinating study revealing that wild animals fear humans even more than they fear lions. Welcome, Michael!
**Michael Clinchy:** Thank you for having me!
**Editor:** Your study has quite intriguing findings. Can you summarize the main takeaway regarding the fear that wildlife has towards humans compared to lions?
**Michael Clinchy:** Absolutely. Our research shows that across various species in the African savanna, the fear of humans significantly exceeds that of lions. This was a surprising conclusion given that lions are apex predators and traditionally considered the scariest animals in the ecosystem.
**Editor:** What motivated you to explore this comparison between human-induced fear and fear of predators like lions?
**Michael Clinchy:** We wanted to understand the dynamics of fear in wildlife and how human presence influences animal behavior. It’s crucial for conservation efforts to comprehend what animals fear most, as it can inform how we manage our interactions with wildlife, especially in regions heavily impacted by human activities.
**Editor:** Could you elaborate on the methodology you used for this study?
**Michael Clinchy:** We conducted over 10,000 observations of various species reacting to the presence of humans versus lions. By systematically documenting these reactions, we were able to quantify the levels of fear expressed by the animals in different scenarios.
**Editor:** That’s an impressive dataset! What implications do your findings have for conservation strategies?
**Michael Clinchy:** The results suggest that wildlife conservation efforts need to prioritize reducing human disturbance in natural habitats. Understanding that animals may alter their behaviors due to fear of humans can inform protective measures, like creating safe zones where wildlife can thrive without the looming threat of human interference.
**Editor:** Do you think the fear of humans could lead to significant changes in animal behavior or even their populations?
**Michael Clinchy:** Absolutely. Fear can influence feeding patterns, breeding, and habitat use. If animals are more fearful of humans, they may avoid certain areas, affecting their access to resources and possibly leading to declines in local populations. The insights from our study could help mitigate these impacts.
**Editor:** It certainly shines a light on the complex relationship between humans and wildlife. Thank you, Michael, for sharing your insights on this important research!
**Michael Clinchy:** Thank you for having me! It’s been a pleasure.
