TOLEDO, Ohio (AP) — Two orphaned cubs of a grizzly bear that killed a hiker in Yellowstone National Park have arrived at an Ohio zoo.

The cubs arrived Tuesday night and will be in quarantine for 30 to 60 days. Officials at the Toledo Zoo say the bears are in good health, but are too young to survive on their own in the wild. The mother of the twin females was killed on Aug. 13 by the U.S. National Park Service after the bear ate part of the Montana hiker's body and hid the rest.

Officials say that wasn't normal behavior for a female bear defending its young. The cubs are less than a year old. Each weighs 60 to 70 pounds. It's been three decades since a brown bear lived at the zoo.
