A Maine wildlife biologist said one of three bear cubs that nearly froze to death is doing well after being placed with a surrogate den.

The Bangor Daily News documented Randy Cross as he checked on the cub Wednesday. He easily recognized the young bruin because of signs of frostbite on the tips of its ears.

Then the cub was placed back in the den.

The three cubs were abandoned after a piece of logging machinery passed close to their ground den in January. Their mother fled the ruckus, and didn't immediately return, and the logger contacted the Maine Warden Service for help.

The cub that was checked on Wednesday was placed in Edinburg. The other two were placed with a mother bear in Orneville.
