Polar bears in Canada's Western Hudson Bay — on the southern edge of the Arctic — are continuing to die in high numbers, a new government survey of the land carnivore has found. Females and bear cubs are having an especially hard time.

Researchers surveyed Western Hudson Bay — home to Churchill, the town called "the Polar Bear Capital of the World," — by air in 2021 and estimated there were 618 bears, compared to the 842 in 2016, when they were last surveyed.
