Ambling through the woodland and shuffle across the tundra , browned bears do n’t exactly give off the image of an active predator like a wolf or cougar . Butnew datacaptured on tv camera hang around their necks has revealed them to be sanguinary sura - killing political machine . Sometimes
Traditionally it is very difficult to fully observe bear over a foresightful period of time , and often only gives results on a population level . For the most part this means that researchers only get a snapshot view of what they endure is doing at any one full point in clip . couple with the fact that comparatively speaking , they spend only a very poor amount of time really track down , it gives a modified picture of what it is they are consuming .
Attaching GPS leash to wild fauna is not common practice among wildlife biologists , but can give some really fascinating insight into what creatures in the natural state get up to aside from the nosiness heart of researchers . The Alaska Department of Fish and Game decide to essay and step this up a level . Over a menses of three age , during the caribou and moose calving season , they outfit 17 barbarian bears with not only GPS trackers but also television camera collar , and published their results in theWildlife Society Bulletin .
film short 10 - second clip every 5 to 15 mo , the cameras pay the researchers an astonishingly intimate opinion into what the bear were grow up to in the wild of the Alaska Dubyuh , from swim in river to union . But what they really wanted to know was what , incisively , they were feeding on . And it become out that the bears are far more marauding than they ever imagined .
While the ursine creatures still spentthe vast majority of their timeresting ( 60.5 pct ) or traveling ( 21.3 percent ) , they spent 6.2 percent of their time give . By retrospect over 100 hr of camera footage , the researchers were mostly able-bodied to deduce what the bears were eat , and whether or not they had kill the prey in the first place , by identifying how fresh it was . And it seems that they are truly fertile hunter .
Over the period canvass , they found that the bears were eating a spacious range of foods from ptarmigans to swans , and even other bears . But most of their diet was coming from moose and Greenland caribou calf , which imposingly accounted for over half of what they were eating ( 52.2 percent ) . Over a period 45 days , they estimate that the bear were defeat on ordinary 34.4 calves . This is far higher than anyone had previously imagined .
