The voting for Fat Bear Week in Katmai National Park — where bears are blessed with a copious supply of sockeye salmon that allows them to fatten up tremendously before hibernating — has opened up, and there are two matches in play on Wednesday. Read more…

In July 2014, a stranded bear cub spent the night clinging to the upper reaches of a spruce tree along the banks of the Brooks River in Katmai National Park, Alaska. 

After spending at least 24 hours curled up amid the branches, the young, largely helpless bear likely succumbed to thirst and hunger, and crawled down. Read more…

For bears, getting fat is a matter of life and death.

It’s been about six months since the brown bears of Alaska’s Katmai National Park — the bears of bear cam fame — emerged from their well-dug winter dens. 

They’ve been munching on copious amounts of 4,500-calorie salmon ever since, putting on hundreds of pounds while thousands of people watched the bears’ fishing antics on the explore.org webcams over the summer. Read more…

Alaska’s badass bears: A battle to reclaim the river’s throne

TwitterFacebook

In the deep Alaskan wilderness, an imposing brown bear has regained his lost throne.

Bear 856 — well known on the explore.org live streaming webcams — had been the dominant bear along Katmai National Park’s Brooks River for at least six years. 

But last summer, Bear 856 appeared skinny and enfeebled. Another large male, Bear 32 — nicknamed “Chunk” by the rangers — exploited 856’s condition and took control of the bear’s dynamic river hierarchy. Rangers watched from elevated bear-viewing platforms as an emboldened Chunk pushed other bears around and claimed the river’s best fishing spots. 

Yet, over the last three and a half months, Bear 856 has reestablished his dominance, even over the likes of formidable Bear 32 and the tank-like Bear 747. At times, 856 has tackled other large bears that have attempted to challenge him, but he hasn’t ceded any ground. Now, the bears are fattening up for their long winter hibernation, and it appears 856 will end the season as the river’s king, once again. Read more…
