This puma (not involved in the study) fed on a single deer for five days. New research suggests these feedings can be interrupted by the puma’s fear of humans. Mountain Lions Are Terrified of Humans—and That’s a Problem. We typically think of large predatory animals like mountain lions as fearless beasts that’ll stop at nothing to procure a meal—even if that meal consists of human flesh. New research suggests that this view is wrong, and that big cats don’t like to bump into us any more than we like to bump into them. Problem is, this fear of humans is altering the feeding behavior of big carnivores, and that may not be a good thing. A study published led by by scientists from UC Santa Cruz and Western University in London, Ontario and published today in Proceedings of the Royal Society B, suggests that mountain lions in the Santa Cruz mountains, sometimes known as pumas or cougars, are spooked by the sound of human voices. These fearful encounters are causing the carnivores to flee their kill sites. Afterwards, some pumas—albeit very slowly and cautiously—will return to their fallen prey, resulting in a 5. To make up for these lost meals, the pumas have to kill more deer, which often requires them to encroach upon human settings. In other words, fear of humans is altering puma behavior, and subsequently, their role in the ecosystem. Big carnivores are scary, both to humans and the animals they prey upon. But as a new study. ![]() Last year, similar work by the same team of researchers confirmed a long- held notion that carnivores perform an important role in ecosystems by inducing fear in their prey. The presence of large predatory animals, the study showed, generates a “landscape of fear” that alters the feeding behavior of prey animals, which subsequently influences their impacts on other species down the food chain. To assess a potential fear response in large carnivores, the researchers placed audio equipment at puma kill sites in the Santa Cruz mountains. Whenever a puma came to feed, its movements triggered a device that broadcast recordings of people having conversations at natural volumes. The researchers used recordings of Pacific tree frog vocalizations as a control. A hidden camera captured images of the animals’ responses, revealing that pumas almost always run away from human voices, but practically never from the sounds of frogs. Across 2. 0 experiments involving 1. Revealingly, pumas took longer to return to their kills after hearing human voices, reducing their feeding on these kills by half. Previous work from these scientists revealed higher kill rates of deer in more urbanized settings, and this finding is finally offering a plausible explanation as to why. Unable to eat the entire carcass in peace, the pumas are forced to kill more deer, which ironically often leads them into contact with more humans. More dead deer may seem trivial, perhaps even potentially beneficial, but the change in hunting habits could be altering the ecosystem in unexpected ways. There are often downstream effects to consider—but future work will have to suss this out. So there is plenty of cause for pumas to fear humans.”As to how pumas learn this behavior, Suraci says that’s a much trickier question. All of the pumas in their study had some form of human habitation or development within their home range, and were likely to have experienced interactions—some of them potentially negative—with people. Suraci says it may also be the case that puma kittens, who spend up to a year with their mom, learn appropriate human avoidance behavior from her.
