Imagine a job where being late because a bear blocked your path is a totally valid excuse. That’s life for rangers in Alaska’s stunning Katmai National Park and Preserve, home to a remarkable population of brown bears. Every year, these incredible creatures embark on a crucial mission: to get as fat as possible, a vital quest for their survival through the long Alaskan winter. This amazing natural spectacle is celebrated in a unique event known as Fat Bear Week, where the American people get to cheer on their favorite bruins as they pack on the pounds.
Far from a stuffy scientific study, Fat Bear Week is a March Madness-style competition that has captured hearts around the globe. Voters tune in to see iconic Katmai bears like Otis and 747 battle it out in a bracket, celebrating not just their impressive size but the health of Katmai’s vibrant ecosystem. It’s a powerful story of wildlife conservation and the raw resilience of nature, showing us how communities come together to appreciate our natural wonders. Join Our American Stories as we dive into this beloved tradition, proving that some of the greatest American tales are found in the wild heart of Alaska.

Speaker 1: This is Lee Habib, and this is Our American Stories. They show where America is the star and the American people. And today we’re going to hear from Leon Law in Alaska. Leon is a ranger at Brooks Camp in Katmai National Park and Preserve, and she’s here to share a story about Fat Bear Week, the March Madness-style bracket where bears compete to be the Fat Bear Champion.

Speaker 2: There aren’t many places that you can work and say, “Sorry, I’m late; there was a bear in my way,” and that be a completely valid excuse. But that does happen at Brooks Camp to rangers as well as visitors. Katmai National Park and Preserve is comprised of just over four million acres or so. It’s located in Southwest Alaska, and one of the things that we are perhaps best known for is our high concentration of brown bears. Bears are not true hibernators. They actually go through a state called torpor, but here in bears enter the den anywhere from late October to early December, and they exit in April or May. But once they enter the den, they don’t eat or drink anything, but rely solely off their fat reserves. So, essentially, they need to eat an entire year’s worth of food in six months or less. During this time in the den, they will lose perhaps about a third of their body weight, and even when they exit the den in spring, it’s still a lean time for them, so bears will continue to lose weight. So it just speaks to the importance of getting fat, essentially, during the waking hours. So Fat Bear Week began in 2014, and it started simply as Fat Bear Tuesday, a one-day competition held on our social media. And the purpose was to highlight the hard work of the bears and our healthy ecosystem here at Katmai. It became so successful that it has now expanded into Fat Bear Week. So, for bears here, fat equals survival and success. A fat bear is a healthy bear. So Fat Bear Week is Katmai’s annual celebration of success and survival. So it is essentially a competition. It is a single-elimination bracket where bears face off head-to-head in matchups, and voters get to choose the ultimate winner. The main bracket consists of twelve different bears, and voters will choose who advances to the next round and ultimately crown the Fat Bear Champion. Unfortunately, our bears aren’t really the kind who would cooperate if we tried to put them on the scale. So, what we can do is we can only estimate their weight. So, a couple of years ago, we did experiment using light oar scanning, which is typically used in civil engineering for scanning buildings or similar things. It provides a measurement of volume, and through that we can kind of get an estimate of weight. So, most adult males weigh 600 to 900 pounds in midsummer, and by October-November, large adult males can weigh well over 1,000 pounds, so you’ll see huge fluctuations. A good example, for instance, is 747, the champion of 2020, and we believe that he is our largest bear known to use Brooks River. He was estimated to weigh 1,400 pounds, so he is a big guy. One of the special things about Katmai is we actually get to see the same bears over and over, and sometimes not just throughout the season, but over the course of several years. And through that, you come to know that each of these bears are individuals: what type of fishing technique they like to use, or where a bear prefers to fish. 80 Otis was last year’s Fat Bear Champion, and actually, that was his fourth title claim. He is one of our older bears here at Brooks, and he employs a sit-and-wait kind of method—a method of patience of letting the fish come to him. And over the course, we get to see bears, not just him, but other bears at well, taken fish after fish. Sometimes we’ve seen bears eat upwards of 40 fish in a day. 128 Grazer, she is really known for being assertive, and we will often see her fishing in prime spots because of her assertiveness. So, 909 was a first-time mom, and she had a spring cub—a first-year in their life cub. And 909 had caught a fish and had brought it over the bank to eat, and we saw this little spring cub charge another bear who had gotten too close and was begging for fish. So we get to witness really incredible interactions. And sometimes food is so plentiful, right, that bears are released from some of that competition for resources. So, we also get to see bears play with bears occasionally. So, what you get to witness at Katmaia is pretty remarkable. We have seen so much positive response to Fat Bear Week. We see people incorporating it into classrooms. We see people campaigning for their favorite bear. People have bracket parties at work, and during Fat Bear Week, we also have many live broadcasts on the bear cams, and people will tune into that and have live watch parties as well. So we see how widespread it really has become, hearing from people all over the world as they participate in voting, and last year we had nearly 800,000 votes cast. So, during Fat Bear Week, we are really holding up Catmi, and specifically Brooks Camp in particular, on a pedestal that truly exemplifies the richness of Catmaia National Park and the Bristol Bay area of Alaska. Fat Bear Week is a celebration of success.

Speaker 1: And a terrific job on the production by Madison, and his special thanks to Leon Law and her work at Catmai National Park and Preserve. This great country. The federal government owns 30 percent or more of all the lands in this great country. The states own another 10 percent, but 40 percent of our country has been preserved by the Congress or state legislatures, and thank goodness for that. We love celebrating the stories of our wildlife in this country. No better story than how Fat Bear Tuesday became Fat Bear Week in Alaska. Here on Our American Stories. Here at Our American Stories, we bring you inspiring stories of history, sports, business, faith, and love. Stories from a great and beautiful country that need to be told.
