LULU GARCIA-NAVARRO, HOST:
And now to this week's big happening in Alaska's Katmai National Park. It's Fat Bear Week, Katmai's annual celebration of bears eating as much as they can before winter hibernation. As NPR's sports correspondent Tom Goldman reports, it's become a hugely popular competition.
TOM GOLDMAN, BYLINE: Who doesn't love big, fat bears - at least from a distance? And who doesn't love filling out a bracket, where winners move on and losers go home? Combine the two, and you've got Fat Bear Week. It's ursine March Madness in October.

GOLDMAN: Katmai's estimated 2,000 bears were whittled down to a bracket with 12. Four of the heavyweights had first-round byes. Voters on the park's Facebook page choose their favorite from each matchup. The winner moves on to the next round.
NAOMI BOAK: I'm going to talk about two favorites that I would keep my eyes on.
GOLDMAN: As the competition got underway a few days ago, Katmai Conservancy media ranger Naomi Boak singled out numbers 435 and the appropriately labeled 747.
BOAK: Who, just by coincidence, is as big as a jumbo jet. He was so big he looked like he was ready to hibernate in July. He is the size of two bears.
GOLDMAN: This isn't fat shaming. It's fat glorifying. These bears prepare for hibernation by eating as much as they can.
BOAK: They lose a third of their body fat over the winter, so they need all that fat to survive.
GOLDMAN: At Katmai, the Fat Bear Week competitors are coastal brown bears along the Brooks River. They dine voraciously on one of the largest sockeye salmon runs in the world. There's a fascinating science to this annual gorging. Boak says a hormone that usually inhibits hunger switches off in the bears this time of year.
Boak and her fellow media ranger Brooklyn White chose the 2019 competitors. They wanted good before and after photos of the 12 - skinny shots from earlier in the year and recent fat ones after feasting - kind of a reverse infomercial. White says they also wanted bears that people knew after watching them on remote bear cams along the Brooks River.
BROOKLYN WHITE: And so many of those folks who, you know, would spend time watching the cams would already have a relationship with a bear that they were seeing in this contest.
GOLDMAN: The bear cams and 5-year-old Fat Bear Week contest are helping people connect with what goes on inside the park and helping extend the park's conservation mission. Last year, there were nearly 56,000 votes for Fat Bear Week. This year, the park hit that number in the first two days.
Obviously, people love fat bears. But there's a line in the park they don't like to cross. They try not to anthropomorphize wild animals in a wild place. That's why they give the bears numbers, although bear cam followers like to add names, like Lefty, Chunk and Grazer from this year's contest or last year's champ, Beadnose, No. 409. Boak says Beadnose is known worldwide but this year is not defending her title.
BOAK: She was a no-show.
GOLDMAN: Boak says they don't know why. Beadnose could have been injured or could have died or gone to another place to fish.
Well, whatever happened, you can say she went out on top, I suppose. Yeah.
BOAK: Absolutely. Yes (laughter).
BOAK: She went out in a big way.
GOLDMAN: In two days, it's Fat Bear Tuesday, when a new champion is crowned with no real top prize other than a long and successful hibernation and lots of new fans.
