It\u2019s a week-long online contest between selected bears in the park, with viewers voting over the internet for the bear which appears to have gained the most weight. This year, the winner was a massive bear called \u201cChunk\u201d.<\/p>\n<p>In the winter, brown bears in Alaska hibernate, lying inactive for months. During this time, they lose up to a third of their body weight. So before their long winter sleep, it\u2019s important for the bears to put on as much weight as possible. For females who might soon be raising cubs, the extra weight is especially important.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.newsbeep.com\/uk\/wp-content\/uploads\/2025\/10\/fat-bear-week-bracket-black.jpg\" alt=\"The Fat Bear Week 2025 \" tournament=\"\" bracket=\"\" width=\"500\" height=\"387\" class=\"size-medium wp-image-26438\"  \/>A massive bear called \u201cChunk\u201d has won Katmai National Park\u2019s Fat Bear Week 2025 contest.

Brown bears eat lots of different foods, including berries and roots. <\/p>\n<p>But the bears know that at this time of year, lots of food can be found in the area\u2019s rivers. That\u2019s because in the summer, sockeye salmon are swimming upstream so they can lay eggs in the same places where they were born.<\/p>\n<p>The contest is focused on bears who spend most of the summer feeding in the Brooks River. One hot spot is Brooks Falls, where the salmon have to jump up a 6 foot (1.8 meter) waterfall to continue upstream.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.newsbeep.com\/uk\/wp-content\/uploads\/2025\/10\/brown-bears-at-brooks-falls-1200.jpg\" alt=\"Brown Bears feeding on sockeye salmon at Brooks Falls, Katmai National Park, Alaska.

But in real life, the bears are competing against each other, too. Putting on weight will help them survive. It will also help them in fights to get good fishing spots on the river.<\/p>\n<p>But this summer, there were plenty of salmon. Park rangers say as many as 200,000 salmon may have made their way up the Brooks River this year. That meant that the bears haven\u2019t had to fight much for food.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.newsbeep.com\/uk\/wp-content\/uploads\/2025\/10\/32chunk-1201.jpg\" alt=\"Before and After pictures of Chunk, the winner of Fat Bear Week 2025.\" width=\"500\" height=\"197\" class=\"size-medium wp-image-26439\"  \/>This year\u2019s big winner was a 1,200 pound (544 kilogram) bear called \u201cChunk\u201d.
