Researchers studied the relationship between wolves and cougars in Yellowstone National Park. They found that wolves often take over prey that cougars have already killed, leading cougars to adjust their hunting habits.

A new study reveals the complex dynamics between wolves and cougars in Yellowstone National Park. The research shows that many encounters between these two apex predators start when wolves take over prey that cougars have already killed. To avoid these risky run-ins, cougars have adjusted their hunting habits by targeting smaller animals. This change helps them spend less time at a carcass, reducing the chance of wolves showing up.

The study also found that cougars tend to steer clear of areas where wolves have recently made kills. They prefer to stay near escape terrain, such as trees they can quickly climb if threatened. As elk numbers declined in Yellowstone, cougars shifted their focus towards deer, which are smaller and can be eaten more quickly.

The research draws on nine years of GPS tracking data from collared wolves and cougars. The findings suggest that peaceful coexistence between these two predators depends less on the total amount of prey available and more on having a variety of prey species and access to safe escape terrain.
