A mountain lion kills a mule deer in the mountains of Montana, and at first glance it looks like a story about death. But it’s also a story about life. That deer may feed the mountain lion for days, but the lion is rarely the only beneficiary. Ravens often arrive first, their sharp eyes scanning the landscape for opportunity. Magpies join the feast. Golden eagles may drop in. Coyotes, foxes, and even bears can take their turn. Mice and voles drag away tiny scraps. Beetles, flies, and countless insects begin their work. Eventually, fungi and microbes return what remains to the soil. The death of one animal can ripple through an entire ecosystem. A single mule deer may provide nourishment to dozens of species, each playing a role in the endless cycle that keeps wild places functioning. What appears harsh to us is often one of nature's most generous acts. I've spent a lifetime following mountain lion tracks, and one of the things they continue to teach me is that predators don't just take life, they distribute it. They move energy across the landscape, feeding a web of creatures most people never see. In the wild, nothing is wasted. Every ending becomes a beginning for something else. That's one of the most beautiful lessons the mountains have to offer.

I’ve learned a lot in the tracks of a mountain lion. Not from seeing them, but from following where they’ve been. Most days, I never lay eyes on the cat itself. Instead, I walk in its footsteps. I study how it interprets the landscape. I see the places it chooses to visit, where it beds, how it moves through hunting areas, where it crosses streams, how it uses the wind, and how it handles terrain that most people never think twice about. One of the things that always amazes me is that mountain lions move across a landscape in ways that humans often can’t, or at least not easily. They’ll sidehill steep slopes, disappear through cliffs, weave through deadfall, and travel routes that can be exhausting just to follow. Keeping up with a mountain lion is often a challenge in itself. Over time, I take all of that information and log it in OnX. And something interesting starts to happen. Patterns emerge. Those patterns become tendencies. And those tendencies begin to teach you how a mountain lion thinks. Not completely, of course. A mountain lion will always keep some secrets. But little by little, you start to understand why it chose one ridge over another, why it traveled a particular drainage, or why it paused in a specific patch of timber. And when you begin to recognize those patterns, you start moving differently yourself. You begin looking at the landscape through a mountain lion’s eyes. That’s when the search changes. Because finding a mountain lion isn’t usually about spotting a cat. It’s about understanding one. And every track in the snow is a clue.

Not long after leaving the trailhead, we cut a set of fresh lion tracks and began following them deep into the mountains. Every track, every turn, and every clue told part of the story, and we knew there was a chance the cat had made a kill nearby. Following a mountain lion on foot is never easy, but these are the moments I live for—reading the landscape and piecing together the movements of an animal that spends its life avoiding detection. Along the way, I discovered a cave tucked into a rocky outcrop and couldn't resist investigating. Crawling inside, I found evidence that it had been used as a bear den in the past. As the day unfolded, the tracks led us to exactly what we were hoping for—a fresh kill. We deployed a team of remote cameras and left them to do their work.

When most people think about bears catching fish, they picture giant brown bears standing in Alaska's salmon streams. But Alaska isn't the only place where bears fish. Right here in the Greater Yellowstone Ecosystem, both grizzly bears and black bears will take advantage of spawning trout when the opportunity presents itself. It's not as common as it once was, but thanks to ongoing conservation efforts, Yellowstone cutthroat trout populations are beginning to rebound in some watersheds. This beautiful brown-phase black bear is trying her luck in a spawning stream, taking shot after shot at Yellowstone cutthroat trout. Not every attempt was successful, but that's part of the story. Wild animals are constantly balancing energy, opportunity, and instinct. It's a reminder that Yellowstone's food web is incredibly connected. Healthy trout populations don't just benefit anglers, they provide food for otters, eagles, ospreys, pelicans, bears, and countless other species that have relied on these fish for thousands of years. Have you ever seen a black bear fishing for trout?

Survival in numbers. A lone wolf could never take down a healthy adult bison. And a lone bison would struggle to defend itself against an entire wolf pack. That’s the reality of the wild, strength often comes through teamwork. In this clip, Team Bison wins. The herd bands together, stands its ground, and the wolves back off. But that’s not always how it ends. Sometimes Team Wolf wins. In recent years, wolves in the Yellowstone ecosystem have been feeding heavily on bison, in some areas making up nearly half their diet. This battle is ancient. Wolves and bison have been shaping each other for tens of thousands of years across North America. Predator and prey. Strategy and defense. Cooperation versus cooperation. And that’s what makes watching it so fascinating. Neither side is evil. Neither side is wrong. It’s survival. It’s evolution. It’s the wild doing what it has always done.

In summer, grizzly bears in the Greater Yellowstone Ecosystem eat more than 266 different species, everything from pine nuts to bison and about everything in between: fungi, berries, grasses, roots, rodents, insects, and even soil. But one of the wildest things they eat is the army cutworm moth. These moths gather by the millions in high alpine talus slopes, and grizzlies will dig through the rocks and lap them up by the tens of thousands, sometimes 40,000 to 60,000 moths in a single day. And honestly… they’re pretty dang good. I’ve tried them over the years, and they taste kind of like a honey-roasted peanut. Sometimes when I’m hiking around up there and need a little extra calorie bump, I’ll dig around for a few moths myself. Each moth is tiny, but it’s basically a little flying fat bomb, packed with calories and protein. No wonder bears climb high into the mountains every summer to find them. If you want to learn more, and see one of the most spectacular grizzly bear events I’ve ever witnessed in my life, head over to Endless Venture and check out the latest episode featuring grizzlies feeding on army cutworm moths high in the mountains. It’s one of the craziest natural spectacles in the Yellowstone ecosystem.
