英语听力：自然百科 北极熊 冰上间谍 Spy_Bear—6

 But again, a bear helps with the filming. Sealed with a kiss, the couple’s whirlwind romance will last three weeks.

 

Out on the frozen sea, a young male has killed a seal. He caught it when it surfaced through a breathing hole in the ice. To film from a different angle, blizzard-cam deploys¹ snowball-cam. This technical miracle rolls with no visible moving parts. Its lens even boast a self-righting mechanism², a close-up reveals that he's eating the blubber. This provides the most nutrition and is always eaten first. Seals make up 95% of a polar bear's diet and are only found near the sea ice.

 

The two cub³ family are attracted to the frozen sea to hunt seals as well. She hunts the pups of ringed seals that hide in snowy dens⁵ on the ice. She finds them by smell, even a meter down. She pile-drives the snow with a force of two tons, but the roof of the den⁴ holds.

 

Back at the carcass, the spy-cams stay on to film bears attracted to the leftovers⁶. The mother and a single cub--she could smell their remains⁷ from 20 miles away. In the den, she spent six months without eating while the males fattened⁸ up on seals.
