TOLEDO, Ohio (AP): Toledo will soon have to say goodbye to its twin polar bears, now nearly 2 years old.

The Toledo Zoo says that brother and sister Sakari (suh-CAR'-ee) and Suka (SOO'-kah), will leave sometime in the fall and move to the Como Park Zoo in St. Paul, Minnesota.

The Blade of Toledo reports (http://bit.ly/1p1L9xR) that the twins' parents, Crystal and Marty, will stay behind, along with another female polar bear.

Toledo's polar bears have successfully reared eight cubs in the last six years. The other four cubs all have moved, too, to other zoos in Ohio, Missouri and Kentucky.

Cubs are moved to mimic polar bear behavior in the wild. They're mostly solitary creatures, and if left together too long, polar bear mothers and their offspring could mate.
