But their world is changing \u2013 which means they must change too. For the first time, the team film a polar bear as it ventures away from the coast and into the mountains in a rarely seen long-distance pursuit of reindeer.\u00a0\u00a0<\/p><figure class=\"wp-block-image size-full\"><figcaption class=\"wp-element-caption\">A female polar bear spots potential prey in Svalbard, Norway.

The Mammals<\/em> crew journey to Alaska\u2019s northern tundra where they observe the surprisingly caring side of these not so mythical creatures.<\/p>In northern Canada a remarkable community of bears have learnt how to fish for salmon late into winter on an unusual ice-free river \u2013\u00a0one final feast before hibernation.<\/p><figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1754\" height=\"1170\" src=\"https:\/\/c02.purpledshub.com\/uploads\/sites\/62\/2024\/04\/Arctic-fox-Mammals.jpg\" alt=\"Arctic fox in snow\" class=\"wp-image-98799\"\/><figcaption class=\"wp-element-caption\">On the shores of Canada’s Hudson Bay, an Arctic fox pauses among the grasses.

Deep underground, hibernating brown bats, with reduced body temperatures and heart rates, are fast asleep. All except one, not-so-sleepy bat, who sees an opportunity.\u00a0<\/p>Bringing new-borns into a world of snow and ice has many challenges, but mammals\u2019 ability to produce fat-rich milk allows harp seal mothers to have one of the shortest weening periods of all. In just 12 days, as the icy nursery melts around them, the mothers race to fatten their pups up before leaving them to fend for themselves.\u00a0<\/p><figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1754\" height=\"1168\" src=\"https:\/\/c02.purpledshub.com\/uploads\/sites\/62\/2024\/04\/Harp-seal-Mammals.jpg\" alt=\"Harp seal in snow\" class=\"wp-image-98801\"\/><figcaption class=\"wp-element-caption\">Portrait of a harp seal (Phoca groenlandicus) pup, Magdalen Islands, Canada.

But for snow leopards, that have evolved over millions of years to live here, it is humans that present to greatest test, not the cold. <\/p><figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1800\" height=\"1200\" src=\"https:\/\/c02.purpledshub.com\/uploads\/sites\/62\/2024\/04\/Snow-leopard-Mammals.jpg\" alt=\"Snow leopard\" class=\"wp-image-98800\"\/><figcaption class=\"wp-element-caption\">A resting snow leopard in China’s Qinghai-Tibet plateau.
