The birth of Victoria the polar bear was announced by Tierpark Hagenbeck in Hamburg, which described it as a “minor sensation” because the zoo hasn’t welcomed a new member of the species in nearly two decades.

Victoria was born on December 19 and was kept in her den for the first several months until staff determined she was “healthy, lively, and alert.”
