JoAnne has just returned from studying polar bears in Churchill, Manitoba, Canada. Read her previous post, Polar Bears: Living in Churchill.
In November 2001, I journeyed to Churchill for the first time to see polar bears. The freezing cold and strong winds from the north stung. I could not believe that an animal that had the same body temperature as me could live in these conditions. I soon saw how incredibly specialized polar bears are for this arctic home. They were all thick furred and very round with the warm insulating blubber from their main prey, ringed seals.
