Fat Bear Week Returns Early With Playful Bears

Fat Bear Week is a fun online event where people vote for their favorite brown bears from Katmai National Park in Alaska. These bears get really big and fat as they eat a lot to prepare for winter sleep. The event helps teach everyone about bears and nature. It started in 2014 and has grown popular worldwide. 

Fans watch live cameras of the bears fishing and playing in the Brooks River. This year, it’s starting earlier than usual on September 23, 2025. Normally, Fat Bear Week begins in early October. But in 2025, it’s kicking off on September 23 because the bears are already super fat.

The salmon run, which is when lots of fish swim up the river, was huge this year. More salmon than in recent years means the bears have plenty to eat. They don’t have to fight as much for food. Instead, they play more and look healthy. Park officials say this abundance makes the bears ready for the contest sooner.

The Amazing Bears of Katmai National Park

Katmai National Park and Preserve is home to about 2,200 brown bears. It’s in southern Alaska near Bristol Bay. The park is famous for its rivers full of salmon, which attract the bears. At the Brooks River, around 80 to 100 bears show up each year.

Many learned to fish there as cubs with their moms. These bears start skinny in spring after waking from hibernation. By fall, they can weigh over 1,000 pounds, especially the big males. The park uses webcams so people everywhere can watch them live.

Famous Bears and Their Stories

Some bears have become stars in Fat Bear Week. Take 128 Grazer, who won in 2023. She’s a mom bear known for protecting her cubs fiercely. Last year, she beat 32 Chunk in a big rematch after he killed one of her cubs. Chunk is a massive bear who showed up this summer with a broken jaw from a fight.

But he healed and kept fishing. He even played gently with the younger bears. Then there’s 480 Otis, an older bear famous for his smart fishing tricks. And 747, nicknamed Bear Force One, might weigh 1,400 pounds. He’s like a jumbo jet on four legs. Each year, new bears join the fun. The 2025 bracket will show 12 bears competing. 

It gets revealed on September 22. Fans look forward to seeing if past winners like Grazer or Otis face fresh faces. There’s also Fat Bear Junior for the cubs, which started on September 19. Cubs are playful and learn from their moms. They eat a lot, too, but they’re smaller. The tournament is single-elimination, meaning losers are out after one round. Voting happens online, and last year, over a million votes came from 100 countries.

How the Voting Works

Voting is easy and open to everyone. You go to the explore.org website or the park’s page. Each day, you pick between two bears in a matchup. The one with more votes moves on. It runs from September 23 to 30, ending with a champion. People vote based on how fat and healthy the bears look in photos. 

Before and after pictures show their transformation. It’s like a sports bracket, but for bears. The event brings people together to celebrate nature. Salmon are key to the bears’ success. Sockeye salmon swim from the ocean to rivers like Brooks to spawn. Bears catch them at falls, using their paws and mouths.

A good salmon run means bears eat thousands of fish. Each bear might eat 30 salmon a day in peak season. This helps them gain hundreds of pounds. Without enough salmon, bears struggle. But this year, the run was record-breaking. It led to less fighting among bears. They share spots better when food is plentiful.

Bear Behavior During Hyperphagia

In late summer, bears enter hyperphagia. That’s a fancy word for super hunger. They eat nonstop to build fat for hibernation. A bear might eat for 20 hours a day. They focus on high-calorie foods like salmon. This fat keeps them alive through winter when they sleep in dens. Without it, they could starve.

In Katmai, bears are experts at this. They fish in different ways: some dive, others wait patiently. This year, with full bellies, bears play more. They wrestle and chase each other for fun. Usually, bears at Brooks Falls crowd and fight for the best fishing spots. But in 2025, things are calmer. Less congregating means more space. 

Park rangers saw fewer scraps. Instead, bears interact playfully. Even big ones like Chunk play with youngsters. This shows how food abundance changes behavior. In 2024, a fight delayed the event when one bear killed another. Grazer’s win was emotional for fans. This year’s peace makes the event more joyful.

Hibernation is how bears survive winter. They dig dens in hills or under trees. Inside, their heart rate slows, and they sleep deeply. But it’s not true sleep; they can wake if needed. Females give birth in dens to tiny cubs. The fat from fall feeds them all winter. In spring, they emerge thin and hungry. They eat plants first, then salmon later. This cycle repeats yearly.
