4 Days, 12 Hours and 39… 38 Minutes Until the Polar Bear Migration Cam Goes Live!
Polar Bears International notes that only pregnant mothers go into den in the winters to safely birth vulnerable cubs. “Most polar bears remain active throughout the year. They have the ability to reduce their metabolic rate when food is scarce and adjust it again when food is abundant.
An example of this are the polar bears that come ashore after the ice melts in Hudson Bay each summer. These bears have no food source and enter a state scientists call walking hibernation.”
