From the Discovery Wildlife Park in Alberta - big cute factor, especially for a such a big bear!  :o ;D

Bear On Ice

Berkley The Bear has discovered a small stream covered in ice and decides to show off her ice skating skills. Berkley is a Kodiak brown bear cub who is currently living at Discovery Wildlife Park in Innisfail, Alberta, Canada. This video brought a smile to my face as itís always fun to see wildlife playing in the great outdoors. If you enjoyed this video and want to learn something interesting watch Counting Bears In Canada.

High-tech cameras suggest polar bears having tougher time hunting

Researchers have attached tiny cameras to polar bears for a bear's-eye view of them hunting on the sea ice, one of a suite of high-tech tools providing what could be the closest look yet at how the iconic animals are coping with a rapidly changing Arctic.

"This study was designed trying to get a much more detailed understanding of what the bears were actually doing on the ice," said researcher Anthony Pagano of the University of California in Santa Cruz.  Pagano wanted to capture hard data on how often bears catch seals and how many they need to keep healthy and strong in their demanding environment. 

He and his colleagues studied nine bears in the Beaufort Sea over the course of about a week during three successive Aprils from 2014 to 2016. They equipped the bears with GPS-enabled video cameras as well as with instruments to measure the speed and distance they travelled, how quickly they burned energy and how much time they spent in the water.  "It allowed us to actually monitor the behaviour of the animals," said Pagano. "(The camera) gave a perspective right underneath the bear's chin."

One big conclusion is that polar bears need a lot more food than previously thought. Scientists have believed that because bears hunt mostly by waiting for a seal to pop through a blowhole, they don't use much energy. Others theorized the bears were able to lower their metabolism during those waits. Wrong, said Pagano. His study concludes bear metabolism is about 60 per cent higher than previous estimates, meaning the animals need to eat that many more seals to maintain weight. "Overall, the metabolic rates of these animals are similar to other marine and terrestrial carnivores. They need to be catching more seals than would have been predicted previously." The cameras recorded footage of bears catching seals and hauling them out of the ice, as well as of bears wrestling with large seals in frigid waters. "It was quite fascinating and really exciting to watch," said Pagano.

Ominously, he found that five of his nine bears lost weight during the study, up to 10 per cent of their body mass. That's despite the study taking place during the time when bears normally have their most successful hunting.  The Beaufort Sea has seen dramatic losses in sea ice. It's population of polar bears is known to be in decline. Pagano cautions the conclusions of his study are tempered by its small sample size and limited time span.

Andrew Derocher, a polar bear biologist at the University of Alberta, warned that there is wide variability between bears and different times of year.  "You might get a very different picture on weight gain from many more individuals," he said. Still, he said, the study backs up others looking at how polar bears are coping with shrinking sea ice, their favourite hunting platform. "Pretty much every component they've found was largely confirmatory in nature," Derocher said. "The true beauty of this work is that it's all integrated at once, in one place, in the same individual bears. You get a much more holistic perspective of the ecology of the bears."

Poor little squirrel.  What horrible teeth.  I hope the trim helps and the teeth now grow properly.  If not, this wonderful person is ready to help out again.

And the fattest bear in Alaska is ... this rotund mother bear
CBC/Thomson Reuters  |  Oct 10, 2018

In an Alaska clash of tubby titans that has become a social media sensation, a shaggy, brown and possibly pregnant mother known as 409 Beadnose was crowned on Tuesday as Fattest Bear of 2018.​​  Beadnose nosed out a larger Alaska brown bear, a male called 747, and likened to a jumbo jet in online votes collected by staff at Katmai National Park and Preserve during a wildly popular event called Fat Bear Week. Male bears are bigger, but Beadnose was deemed to be more rotund.  Her radiant rolls were deemed by the voting public to be this year's most fabulous flab, the park said on its Facebook page.  "Our chubby champ has a few more weeks to chow down on lingering salmon carcasses before she heads up the mountains to dig herself a den and savour her victory." 

Katmai, which hugs the mountainous Gulf of Alaska coast, is known for its massive, salmon-chomping ursine residents.

GORGING IN PREPARATION FOR WINTER

October, the month before bears go into their dens to hibernate, is when the animals work the hardest to build the body fat they need to survive winter. And October is a perfect time for nature lovers to watch Katmai's livestream video as the park's brown bears do their pre-hibernation gorging.  Fat Bear Week may be fun and games for human spectators, but it is serious business for bears, said Andrew LaValle, a Katmai ranger who is in charge of most of the park's social media postings.

"This might be entertaining, especially with these beautiful, majestic animals, but this is a life-or-death struggle," he said.  The bears have to eat a year's worth of food in a few months but really start to chow down in June when sockeye salmon begin swimming upstream through the park to spawn. Bears can lose a third of their body weight while hibernating, LaValle said.

Fat Bear Week got its start in 2014 as a one-day educational event called Fat Bear Tuesday, LaValle said. It became a week-long event the next year.  Throughout the past week, park staffers have posted photos of individual bears and gathered input from viewers who selected ​favourites in a bracketed, tournament-style competition. This year's competition started with 12 bears before reaching ​Tuesday's Beadnose-747 faceoff.

Luckily for Katmai bears, their home holds a river teeming with fish from the world's largest natural salmon runs. The Brooks River is a spawning site for salmon based in southwestern ​Alaska's Bristol Bay.
