The annual Fat Bear Week is underway, which means that now is your chance to celebrate the creatures as they prepare for the winter. The week-long celebration, which began on Wednesday, asks folks to vote for their favorite bear at Brooks River in Alaska’s Katmai National Park. They get to choose who has most successfully gotten in hibernation shape before the winter.

Fans of the colossal creatures can vote until Tuesday in this single-elimination bracket competition. It’s like March Madness, but for bears that eat everything in sight. The chart contains the bears’ names, numbers and pictures. Over the next five days, you can vote for these burly creatures, such as Chunk, Holly and Grazer.

Despite the pandemic canceling and postponing countless events, Fat Bear Week is still able to take place. To participate, simply vote online for the chunky champion you think is fattest in each face-off (snout-off?), and the bear with the most votes advances. Voting is open online daily from 12 p.m. to 10 p.m. EST, until “Fat Bear Tuesday,” October 6.

The tournament began in 2014, and Holly, known as the Queen of Corpulence, has been the reigning champion. Whether or not she will be dethroned this time around by Otis, another hefty competitor, remains to be seen.

As per Explore.org, “Their winter survival depends on accumulating ample fat reserves before entering the den. Katmai’s brown bears are at their fattest in late summer and early fall after a summer spent trying to satisfy their profound hunger.”

In Brooks River, the bears feast on salmon from late June until mid-October in order to bulk up for the winter.

“A fat bear is a healthy bear, and it’s something to celebrate,” former Katmai National Park ranger Andrew Lavalle told CBS in 2018. He added that bears must consume a year’s worth of food in the six months.

The bears in this national park are some of the largest in the world, weighing 600 to 900 pounds, The Guardian reported. Additionally, they can weigh over 1,000 pounds before hibernation begins.

Whether the bears make it through the winter months, where they lose roughly one-third of their body weight, depends on if they accumulate enough body fat before entering their den.

Folks can check up on the bears with a live camera set up in the Katmai National Park and Preserve.
