Scientists Observe Polar Bear Cubs Emerging From Dens For First Time Ever

Researchers have revealed astonishing new insights into the lives of polar bear cubs by studying them as they emerge from their dens. The scientists' study includes the first detailed footage of polar bear cubs emerging from their dens in Svalbard, Norway, following nearly a decade of remote camera monitoring. The study was published on 27 February 2025 in the Journal of Wildlife Management to coincide with International Polar Bear Day. It combines satellite tracking collars with remote cameras to uncover new insights into polar bear denning – a period crucial to cub survival. The research found that polar bear families in Svalbard typically emerged from their dens around 9 March – earlier than previously recorded. On average, polar bear families stayed near their dens for 12 days before departing, though this varied from 2 to 31 days. Some mothers were observed leaving their original dens and relocating their cubs to new sites. The Cubs were highly dependent on their mothers, venturing outside alone only 5% of the time. In Svalbard, cubs typically remain with their mothers for up to 2.5 years. The scientists hope that their research can help the bears survive climate change and reduce human conflict as humans increasingly utilise the Arctic.
