Another fact emerges on frigid bear poise — some are hoarders

Another fact into one of a Arctic’s tip predators is being filled in, with a new investigate on how they act after murdering their prey.  

Scientists have always suspicion of frigid bears as quick eaters, chowing down on a choicest cuts of seal, walrus and whale right after they’ve killed it. 

But that’s not always a case, as some confirm to store their kills for later, identical to a poise common among their grizzly bear cousins. 

That’s a finish from a new paper co-authored by Ian Stirling during a University of Alberta. It was published this week in Arctic Science and lists scarcely 20 opposite sightings of frigid bears hoarding their kills over a past 30 years.

That’s something Stirling hasn’t seen or listened of a bears doing in his 49 years of study them. Though it’s odd behaviour, it illustrates a evolutionary couple between frigid bears and grizzlies, he explained. 

“Polar bears usually distant from grizzly bears and became opposite animals about a half-million years ago,” he said. “In evolutionary time, that’s only a blink of an eye.” 

Stirling says it appears many frigid bears have stopped hoarding their food since they simply don’t need to as a peak predator on a sea ice. But that instinct is there when they need it to be. 

Polar bears cover their food, a purpose of it, is for a beef or weep to be cooled off, after it cools, a bear will eat it-David Iqaqrialu, Inuk elder, Clyde River

“The categorical thing they’re perplexing to do is revoke [the chance] of other bears saying it and entrance over,” Stirling said. “One of a things a bears evidence in out on a sea ice is anything that’s dim or stands out in contrariety with a snow.” 

“By putting some sleet over a body along a shoreline, they’re perplexing to keep some competitors from maybe perplexing to take it divided from them,” Stirling said. 

During Stirling’s time operative with Inuit hunters, this form of hoarding poise never came adult in discussions, that done him extraordinary about either a bears indeed did it. 

“I’m not suggesting for a impulse that hunters haven’t seen this from time to time, we only haven’t listened them speak about it,” he said.     

‘This is for survival’ 

David Iqaqrialu, a well-respected elder from Clyde River, Nunavut, says he’s not astounded a scientists celebrated this behaviour. 

He’s spent most of his life on a land with a bears and knows it’s happened before

“Polar bears cover their food, a purpose of it, is for a beef or weep to be cooled off, after it cools, a bear will eat it,” he pronounced in Inuktitut. 

“If a beef that a frigid bear ate isn’t finished, [the bear] will go behind to it, lapse to it and eat a remains,” he said. “This is for survival.” 

Iqaqrialu said polar bears play a vital purpose in Inuit life and it stays critical for humans to honour them. 

“Our ancestors used frigid bears, approach behind afterwards it was critical traditionally,” he said. “Even to this day, frigid bears are critical to Inuit.” 

But Lennie Emaghok, a hunter and elder from Tuktoyaktuk, N.W.T., says he’s never seen a hoarding before, ancillary Stirling’s commentary that this is singular behaviour. 

In his experience, frigid bears mostly pierce from place to place, frequency staying in one mark for long, Emaghok said.   

Stirling’s take on the research is that it’s another square of information — like a brush cadence in a portrayal — that might not be a vital find now, though could infer critical in a bargain of frigid bears in a future. 

“Down a road, we finish adult anticipating a conspicuous series of these kinds of things fit into a bigger nonplus and assistance we know a animals better,” he said.
