Lincoln Park Zoo now has a female polar bear on premises, too, meaning that there are now potential breeding pairs of the vulnerable species at both the Chicago zoo and at Brookfield Zoo.

The newest female is Kobe, a 17-year-old most recently at Pittsburgh Zoo. She is currently on quarantine but has access to a portion of the exhibit space she will share with Siku, a 7-year-old male who has been in Lincoln Park Zoo’s new polar bear habitat since it opened in November.

The two have been matched by the Species Survival Program at North American zoos that manages polar bear populations in hopes of optimizing breeding and genetic diversity. Introduction of the two animals toward that end will come at a future date.
