Yellowstone Cougars Are Adapting to Wolves in Real Time

There have been mountain lions preying on animals in Yellowstone long before wolves were reintroduced. But now, the rules of the game have changed. Cougars have even shifted their behavior and diet to stay clear of wolves, according to the Montana Outdoor Radio Show. Studies show it's because wolves are not just competition, they’re a downright threat.

Wolves steal kills. Wolves chase cougars off carcasses. Sometimes they kill cougars outright. It is a tough lesson to take, and it seems the cougars got it.

Smaller Prey, Faster Meals

And one of the most striking changes is what the cougars are eating. Cougars, rather than killing as many elk as possible, have begun picking off more deer. It may not be exactly a dramatic conclusion, but it absolutely does make sense. An antlered elk is a long-term investment. It is slow to finish, and it makes a large scent trail around your outdoor space that basically says, “Free buffet over here.”

Deer are smaller. Easier to move. Easier to eat quickly. The less time spent on a body, the lower the risk that it will attract a pack of wolves, acting like it owns the place. Because they do.

Hunting Smarter, Not Harder

Cougars were also found to be moving where they hunt and travel. They avoid areas where wolves hang out. They avoid wolf kills. They shadow closer to rocky landscapes and fleeing cover, where wolves are less effective.

That is evolutionary hunting in real time. Not the slow kind. The survival kind.

This isn’t cougars “beating” wolves. That’s cougars learning to blend in so they can continue hunting without constantly being jumped. In Yellowstone, the hunters are out there stalking more than prey. They are stalking eachother.
