Every year, as the leaves turn golden and rivers grow colder, something extraordinary happens in the wilds of Alaska. Massive brown bears gather along streams to feast on salmon, preparing for their long winter hibernation. But there’s more to this seasonal ritual than just survival. This is Fat Bear Week — a unique, delightful, and surprisingly competitive celebration of nature’s most well-fed bears.
If you’ve ever wondered why people across the world get excited about watching bears gain weight, or how this quirky event grew into an online sensation, you’re in for a treat. Let’s dive deep into the story behind this bear-sized phenomenon.
The Origins of Fat Bear Week
Fat Bear Week didn’t start as a viral internet event. It began quietly in Katmai National Park and Preserve, a remote wilderness in Alaska known for its thriving brown bear population.
In 2014, park rangers came up with a simple idea: create a friendly online contest to help people connect with wildlife. They posted “before and after” photos of bears — one from early summer, when the bears were lean, and another from autumn, after months of gorging on salmon.
People voted for their favorite transformation, and just like that, the first Fat Bear Tuesday was born. By the next year, it expanded into a full Fat Bear Week, complete with brackets, matchups, and enthusiastic fans.
Why Bears Get Fat Before Winter
Before we explore the contest, it helps to understand why bears bulk up.
Brown bears rely on their fat reserves to survive months of hibernation. During this time, they don’t eat, drink, or even use the bathroom. Their bodies enter a state of slowed metabolism, living entirely off the stored fat.
Think of it like stocking up your pantry for a months-long snowstorm. Except, instead of canned beans and pasta, bears store calories in the form of fat. The bigger the fat reserves, the better their chances of surviving the long, cold Alaskan winter — and for females, ensuring their cubs survive too.
Salmon: The Superfood of the Alaskan Wilderness
So where does all this fat come from? Salmon — lots of it.
During summer, millions of salmon swim upstream to spawn. This creates a buffet for the bears. They gather near Brooks River, where salmon jump up waterfalls, practically into their jaws. It’s like an all-you-can-eat seafood restaurant — only furrier and louder.
Some bears eat tens of thousands of calories a day. To put that into perspective, that’s like a human eating hundreds of hamburgers daily. It’s a feast that fuels their survival, and their rapidly expanding bellies.
How the Competition Works
Fat Bear Week has a tournament-style bracket, similar to sports playoffs. Park staff select around a dozen bears who have shown impressive weight gain over the season.
Each day, two bears face off in an online matchup, and the public votes for their favorite. The bear with the most votes advances to the next round, and the process continues until one plump champion is crowned.
Photos and descriptions of each bear are shared to help voters choose. You might read about a young upstart making a big transformation, or an old veteran with legendary fishing skills. Every bear has a story, which makes the competition more engaging.
Meet the Famous Fat Bears
Over the years, several bears have become household names (at least among bear fans).
Otis (Bear 480)
Otis is a legend. He’s an older bear known for his patient fishing technique. Rather than chasing salmon frantically, he sits calmly in the falls, waiting for fish to come to him. Year after year, Otis has wowed fans by transforming from a scruffy, thin bear into a round, fuzzy champion.
Holly (Bear 435)
Holly has been both Fat Bear Week Champion and Mama Bear of the Year. She’s admired for her nurturing nature and her ability to put on serious weight while raising cubs.
747 (a.k.a. “Bear Force One”)
This massive bear earned his nickname because of his airplane-like size. 747 is one of the largest bears ever seen in Katmai, tipping the scales at an estimated 1,400 pounds at his peak. His victories have made him a fan favorite and a symbol of bear magnificence.
Why People Love Fat Bear Week
At first glance, Fat Bear Week might seem like a silly internet competition. But its appeal runs deeper.
-
It’s fun and wholesome. In a world full of heated online debates, this is one of the few contests where everyone can agree: the fattest bear deserves to win.

The Role of Katmai National Park
Katmai isn’t just the stage for Fat Bear Week — it’s a critical sanctuary for brown bears and salmon. The park spans over 4 million acres, preserving rivers, forests, and tundra.
Rangers and scientists work year-round to monitor bear populations, protect salmon runs, and ensure human activity doesn’t disturb the delicate balance of the ecosystem. Fat Bear Week also raises awareness about why these wild spaces matter and why they need protection for future generations.
The Power of Live Webcams
One of the most exciting ways to experience Fat Bear Week is through the live bear cams set up at Brooks Falls. These cameras stream 24/7 during the salmon run, allowing people around the world to watch bears fish, play, nap, and — of course — get plump.
It’s mesmerizing. You might find yourself watching for a few minutes and end up staying for hours, fascinated by their behavior. Some viewers even give unofficial nicknames to the bears they see regularly, creating a warm sense of community.
What Fat Bear Week Teaches Us About Conservation
Beyond the fun and fanfare, Fat Bear Week has a serious side. It highlights how healthy ecosystems are interconnected.
-
Salmon rely on clean, cold rivers to thrive.

Bears rely on salmon for food.
