The Louisville Zoo is getting another polar bear cub for its Glacier Run exhibit. Zoo director John Walczak says Siku, a 22 month old male cub, will arrive in Louisville early this fall from the Toledo, Ohio Zoo. "Our hope is that in the not too distant future that Siku will become best friends with Qannik, our female cub that we helped rescue from the North Slope in Alaska. She was the female abandoned by her mom back in April. This is just creating a great future for Glazier Run and polar bears here in Louisville," he said. Walczak says it’s hoped that the two young polar bears can eventually be bred. Glacier Run is also home to an adult female polar bear and three grizzly bears.
