Fat Bear Week 2021 Starts on September 29 in Katmai National Park

Located in a remote coastal area of southern Alaska, Katmai National Park is a haven for brown bears. It is quite possibly the most amazing place in the world to see these big bruins. In late-summer, dozens of bears gather at the falls of the Brooks River to gorge on migrating salmon, reaching its climax during Fat Bear Week.

In September and October, right before winter arrives at Katmai, the bears eat as much as they possibly can, a feeding frenzy called “hyperphagia.” Thanks to an abundance of food, especially salmon, many brown bears get very big this time of year.

As a celebration of this seasonal event, Katmai National Park hosts an annual Fat Bear Week. During this fun week, you can vote for the fattest bear of the Brooks River.

Each day, you can cast a vote for your favorite bears, which may or may not advance to the next round, ultimately ending with the crowning of the Fat Bear Week Champion.

This year, Fat Bear Week starts on September 29, the National Park Service announced in a press release.

Despite a late salmon run, there are record numbers of brown bears at the Brooks River this year, patiently awaiting the arrival of calorie-packed salmon.

“Can 747, last year’s champion, stay atop the hierarchy of rotund royalty? Will 435 ‘Holly’ or 480 ‘Otis’ reclaim the championship? Is this the year 32 ‘Chunk,’ 151 ‘Walker’ or 128 ‘Grazer’ can claim a maiden victory? Could some other blubbery bear grab the attention with their weight and steal the votes from past favorites?”

As the bears fill their bellies with salmon, you can cost your votes in head-to-head matchups of “stout sows” and “bulky boars.” Fat Bear Week 2021 in Katmai National Park runs from September 29 to October 5.

Additionally, this year, there are also two extra days when you can vote for your favorite Fat Bear Junior, the fattest bear cubs in other words. Those days are September 23 and 24.

You can find the Fat Bear Week schedule, competing bears, a Hall of Champions and tons more information on https://www.explore.org/fat-bear-week. That’s also where you can cast your votes and watch a live webcam.

I've been mesmerized by the bears on Brooks Falls. Lately I've seen two bears there day and night, one in the far pool and one skimming the whitewater below the favorite lip. I'm new at this, so can you identify who these persistent bears are? I'm rooting for them!

Yes, aren't they fascinating to watch! I'm not really an expert in bear identification, but you could leave a comment on the Fat Bear Week website (https://www.explore.org/fat-bear-week) on the bottom of the page. Someone there might be in a better position to help you.
