Being the largest land carnivore in the world, there's not a lot that can scare a polar bear, with the exception of a sow with first time cubs.
The polar bears in Hudson Bay seem pretty relaxed as they await the build up of pack ice in Hudson Bay and spend most of their time sleeping or resting. Once the ice arrives these majestic animals will be on the move and hunting vigorously, but during October and November when the bears congregate on the shores of Hudson Bay they are mostly relaxed and conserving their energy.
