Some Hudson Bay polar bears nearing starvation due to climate change: experts - Winnipeg Free Press

WINNIPEG - Experts say the slow formation of winter ice on Hudson Bay this year has pushed some polar bears to the brink of starvation.

The bears weren't able to get onto the ice to hunt until late November this year and some had to resort to eating from old garbage dumps around Churchill, Man.

...Peter Ewins with the World Wildlife Fund says he saw starving polar bears during a visit in mid-November, signalling the population is in deep trouble.

On Nov. 17, Manitoba Conservation, along with the WWF, Polar Bears International, and York Factory First Nation Resource Management Board, conducted an aerial survey of 333 polar bears along Hudson Bay's western coast. The bears had been off the ice since July 15.

The results were "surprisingly pleasant," said Darryll Hedman, a regional wildlife manager for the provincial agency.

Many of the mostly single, adult males were relatively fat, with "wide rear ends" and a belly "with a dish to it," Hedman said. Cubs were also considered to be doing well, based on how their fat rippled when they ran.

"As far as I'm concerned, the condition of the bears that we've seen in the last couple of days, they're doing OK," he said. "The condition of them was good."
