The first point of view video from a polar bear in the Arctic shows what the world looks like from the bear's perspective, according to the U.S. Geological Survey.
USGS scientists obtained the footage from cameras that were attached to the collars of four female polar bears on the Arctic sea ice north of Prudhoe Bay, Alaska.

"We deployed two video cameras in 2013, but did not get any footage because the batteries weren't able to handle the Arctic temperatures," Todd Atwood, research leader for the USGS Polar Bear Research Program, said. "We used different cameras this year, and we are thrilled to see that the new cameras worked."
The cameras recorded two polar bears that seem to be checking each other out pre-mating. They also captured a bloody seal meal, including how bears solve what must be a common problem in Polar Regions: what to do when your dinner freezes into a rock hard block. The answer to that and more is in the following:
The collars came off after 8-10 days, so the video only shows a snippet of what goes on in the bears' lives. But the researchers are still studying the footage, hoping to learn more about how often the bears hunt, eat, rest, walk and swim, and how the behaviors might be affected by sea ice conditions and other variables.

The research is part of the ongoing USGS Changing Arctic Ecosystems Initiative. It's also relevant to a Polar Bear Conservation Management Plan, now being drafted by the US Fish and Wildlife Service's Polar Bear Recovery Team (which includes the USGS).
The plan, when finalized, will guide activities for polar bear conservation. Other studies have already concluded that continued loss of sea ice habitat due to global climate change is really hurting the bears.
Why Polar Bears Are Fat, But Have Healthy Hearts
For example, The IUCN Red List of Threatened Species holds that polar bear populations have dropped by more than 30 percent within just three generations (45 years) due to the habitat decline. Some animal experts even predict that polar bears could become extinct within 100 years.
Our world is changing very quickly. Future generations might look at the recorded footage, remembering what once was. But hopefully the new plan can be finalized, take effect and be enforced soon, saving these majestic animals of the Arctic.

Mike Lockhart, a biologist with Polar Bears International, was part of a Manitoba Conservation team conducting an aerial survey of the bears of Canada’s Western Hudson Bay late last year when the crew came across an adult male and a smaller subadult feasting on the carcass of a freshly-killed seal. There was nothing unusual about that. What caught the scientists’ attention was the fact that, about 400 meters away, a female with two young cubs was heading straight for them. Polar bear mothers are often extremely cautious and nervous in the presence of large males, and for good reason. Although cannibalistic attacks are rare, they do happen. As they watched the female make a beeline for the kill, with her cubs perhaps 100 meters behind her, Lockhart and his colleagues braced themselves for the worst. “All of us in the helicopter were sure we were going to see a cub wiped out,” he told Discovery News.

Instead, the mother simply joined in the feast, and, after initially standing back hesitantly, the cubs joined in. The large male is in the top right of this picture. Adult males can frequently weigh over 1,000 pounds, several hundred pounds more than females, and are accordingly far stronger. That a female should place herself and her cubs in such apparent danger was unusual in itself. What happened next was all the more so.

“She was there feeding," recalls Lockhart. "They were all feeding. Then all of a sudden ... she just started batting the male around, pushing him back. She did that several times. He tried to get a little bit closer and she’d keep chasing him off.” Perhaps, speculates Steven Amstrup, Polar Bears International’s chief scientist, the female could sense that “the male was a bit tentative. It recently could have fed and was not strongly motivated by hunger. Or ... she could tell he was more tentative than other big males might have been when on a kill.” Or perhaps extreme hunger overtook her initial caution before her defensive instincts kicked in. But, while both men add the caveat that judging a bear’s condition from the air is a highly suspect enterprise, Amstrup notes that “although I’ve seen fatter bears, they aren’t emaciated either.”

Remarkably, the cubs even joined their mother’s pursuit of the male. “She moved the big bear quite a ways away from the kill,” Lockhart says. “The cubs initially stayed at the kill, but then they came right up behind her, and they were all hackled up and you could see their lips curled. It may have been just fear. I have no idea. They could have run the other way, but instead they came right to her.” Amid all the commotion, the subadult bear kept on feeding. “I think he’s the one who made the kill," Lockhart said. "He had a pretty big gut and I think he ate a lot of it. But he never budged. He just stayed there with all the excitement that was going on with the other bears.”

It's not unprecedented for a polar bear mother to shoo away an adult male that she feels is too close. But to actively head toward a kill where a large male is feeding, and then to chase that male away, is behavior that neither Lockhart nor Amstrup have seen before. “I think what it says is that it may be a question of the size of the fight in the bear rather than the size of the bear in the fight,” observes Amstrup. “A motivated female with cubs might be more aggressive, and males, even though they could kill a female if they wanted to, are probably going to get injured in the process. And so depending on the circumstances, it may be healthier for them to back down. It really is a good example that a female with young can be a pretty impressive fighting force.”
