There's a kind of a Mrs. Robinson vibe to the story. Berlin is 23, and Nikita is 6. Despite her advanced age, Berlin has never had a cub, and Nikita has never "paired," to use the zookeeper parlance. Berlin moved to the Kansas City Zoo from the Lake Superior Zoo in Duluth, Minnesota, in December.
The coitus is promising news for zoos and polar bears. The couple has shared a habitat since February, and they were placed together in an effort to boost the number of polar bears in captivity. KCTV Channel 5 reports that there are only 68 polar bears in American zoos currently, and only 35 can breed.
Still, as with all childbearing matters, it's too soon to get excited. Randy Wisthoff, Kansas City Zoo director, told Channel 5. "We're just happy they are getting along right now." If Berlin is pregnant, she will be due in December or January.
