Nature isn't always a Disney movie. Usually, when we talk about Fat Bear Week 2024, it’s all about the "chonk"—those glorious, wobbling mounds of adipose tissue that signify a grizzly bear’s readiness for winter. But this year felt different. It was heavy.
If you followed the bracket at Katmai National Park and Preserve this past October, you know exactly what I’m talking about. We weren't just looking at calories; we were looking at survival in its most brutal, unvarnished form.
Fat Bear Week 2024 was defined by a heartbreaking incident before the voting even started. On September 30, bear 402—a legendary matriarch and one of the most prolific mothers in the Brooks River—was killed by bear 469. It happened right in front of the explore.org live cams. People were devastated. This wasn't just some data point on a wildlife spreadsheet. It was a witness to the raw, competitive pressure these animals face to secure the best fishing spots before the snow flies.
The Queen Retains Her Crown: Grazer’s Dominance
Despite the somber start, the competition moved forward because, well, the bears don't stop eating just because we’re grieving. 128 Grazer ultimately took the title. Again.
She didn't just win; she annihilated the competition. In the final round against the massive male 124 "Chunk," Grazer secured over 71,000 votes compared to his 40,000. It’s rare to see a female dominate the bracket like this, especially against a male who likely weighed several hundred pounds more than her. But Grazer isn't your average bear. She’s famously defensive, a "supermom" who has spent years terrorizing much larger bears to protect her cubs. That reputation for toughness resonates with the public.
Basically, Grazer represents the grit required to survive in the Alaskan wild. She’s not just fat; she’s formidable.

You have to understand the scale here. We are talking about bears that can gain four pounds of fat per day. By the time the 2024 competition rolled around, these animals were literal spheres. They have to be. During hibernation, they’ll lose a third of their body weight. If they don't pack on the pounds in late summer and early fall, they simply don't wake up in the spring.
Why 2024 Felt Like a Turning Point for Conservation
The drama of Fat Bear Week 2024 brought a lot of "casuals" into the fold of wildlife conservation. That’s the real win. While we laugh at the "muffin tops" and the "thunder thighs," the underlying reality is that the Bristol Bay watershed is a fragile ecosystem under constant threat.
The 2024 season saw a relatively late salmon run. This put everyone on edge. When the fish are late, the bears get desperate. Desperate bears are aggressive bears. This context explains why the fight between 402 and 469 happened in the first place. It wasn't "cruelty." It was a high-stakes resource war.
Katmai’s former resident naturalist, Mike Fitz, often points out that these bears are the ambassadors for the salmon. No salmon, no fat bears. It’s a simple equation, but one that requires massive political and environmental effort to maintain. The 2024 tournament served as a megaphone for the "Save Bristol Bay" initiatives, reminding everyone that the Pebble Mine and other industrial threats haven't just disappeared.
The Contenders Who Almost Made It
We can’t talk about 2024 without mentioning 901. She’s a younger sow who has become a fan favorite for her incredibly round shape and "floof" factor. She made a deep run, but she couldn't quite topple the established titans.

Then there’s 747. "Bear Force One." He’s a multi-year champion and arguably the largest bear on the river, potentially tipping the scales at over 1,400 pounds. In 2024, he looked like a dark, fuzzy boulder. However, the voters seemed to favor the narrative of the resilient female over the sheer bulk of the established kings this time around. It's kinda interesting how the "plot" of the river influences the voting. It’s not just a beauty pageant; it’s a story.
124 Chunk also deserves a shoutout. He’s historically been a bit of a cowardly giant—huge but hesitant to use his size to bully others. In recent years, and especially in 2024, his personality shifted. He became more assertive, taking over the "lip" of the falls, which is the prime real estate for catching jumping salmon. Seeing his growth from a shy subordinate to a top-tier dominant male is why people get addicted to these cams.
The Science of the "Fat"
So, how do they get that big? It’s a process called hyperphagia.
In this state, a bear’s biological "off" switch for hunger is completely disabled. They eat until they literally cannot fit another fish in their stomach, then they rest, then they eat again. They’re looking for the highest calorie-density possible. This is why you’ll see a bear catch a salmon, eat only the skin, brains, and eggs (the fattiest parts), and discard the rest. It’s called "high-grading."
It seems wasteful, but when you're 128 Grazer and you need to survive six months of fasting, you don't waste time on lean protein.

How to Support the Brooks River Bears Year-Round
Fat Bear Week is a blast, but the ecosystem needs eyes on it 365 days a year. The 2024 season proved that nature is unpredictable and often harsh.
If you want to move beyond just voting in a bracket, there are specific steps you can take to ensure these bears have a river to return to next year.
First, support the Katmai Conservancy. They fund the actual boots-on-the-ground work in the park, including trail maintenance and bear-human conflict prevention. When tourists flock to the Brooks Falls viewing platforms, it takes a lot of management to make sure we don't stress the bears out.
Second, get involved in Bristol Bay protection. The fight against large-scale mining in this region is ongoing. The salmon runs that fuel these bears are the most productive in the world, but they rely on pristine water quality. Even if you don't live in Alaska, your voice in federal environmental policy matters.
Third, keep watching. The explore.org cams aren't just for entertainment. They provide a massive amount of "community science" data. By watching the bears’ behavior, biologists can track health trends and population shifts that would be impossible to monitor with a small team of rangers alone.
Fat Bear Week 2024 reminded us that the "fat" is a triumph of survival against staggering odds. It’s about the resilience of Grazer, the legacy of 402, and the incredible, calorie-dense miracle of the sockeye salmon. Until next year, keep an eye on the river.
