First-Ever Footage Captures Polar Bear Cubs Emerging From Arctic Dens

A decade-long study using remote cameras and GPS collars reveals new insights into polar bear denning behavior in Svalbard, Norway.

  • Researchers combined satellite tracking collars and remote cameras to document polar bear cubs leaving their dens for the first time in Svalbard, Norway.
  • The study highlights the critical role of maternal dens in cub survival, with fewer than 50% of cubs typically surviving to adulthood.
  • Findings indicate polar bear families are leaving their dens earlier in the spring than previously recorded, potentially due to climate change, though further monitoring is needed.
  • Cubs rely heavily on their mothers during this vulnerable period, rarely venturing outside the den alone and staying close for up to 2.5 years.
  • The research underscores the need to protect denning habitats as industrial activity and climate-driven changes increasingly threaten Arctic ecosystems.
