Three Alaska grizzly bear cubs orphaned when their mother was killed soon will be calling the Detroit Zoo home.

The 11-month-old brothers were orphaned in October when their mother was shot. After the hungry cubs were seen numerous times looking for food in backyards and around homes, the Alaska Department of Fish and Game decided to capture them.

The first cub, named Boo, was brought to the Alaska Zoo on Halloween. The other two, Mike and Thor, joined their brother a few days later.

Alaska Zoo executive director Pat Lampi says the plan is to fly the cubs to Detroit in about two weeks. He says in the meantime the cubs are having fun at the zoo, playing in snow and digging for sticks.
