National Geographic Travelさんのインスタグラム写真 - (National Geographic TravelInstagram)「Photo by @DaisyGilardini | Polar bears lead solitary lives for the most part. Every year, though, in October and November, they congregate around Hudson’s Bay in Manitoba, and wait for bay to freeze before heading out to hunt seals on the pack ice. Play fighting between sub-adults is common during the long wait for the ice to freeze. This behaviour is good practice for the more serious competition during mating season.
