"Despite being the largest land carnivore and a top Arctic predator that can
weigh over 600 kg, polar bears start off surprisingly small. Blind, almost
hairless, and weighing just 600g at birth, cubs are born in maternity dens
under the snow. These snow caves keep newborns warm and safe for the first few
months of their life, when they grow rapidly by nursing on their mother’s rich
milk.
After three to four months in the den, cubs will have grown to about 20 times
their birth weight and will be large enough and furry enough to follow their
mothers out into the frigid Arctic spring.
In a study published in
The Journal of Wildlife Management, we used remote
cameras to study polar bear families as they emerged from their dens in
Svalbard, Norway, gaining insight into the behaviour of mothers and cubs as
they experience the world outside the den for the first time."
