FILE - This Thursday, March 10, 2016 file photo provided by the U.S. Fish and Wildlife Service shows an orphaned bear cub that was rescued after the death of its mother held by Principle Deputy Undersecretary of the Interior Michael Bean, in Tallulah, La. The orphaned bear cub now has a feisty and loving foster mother. Maria Davidson, the head of Louisiana's large carnivore program, says she was able to leave the cub with a new bear family Saturday, Feb. 19, 2016, in the Tensas River National Wildlife Refuge. The orphaned cub's mother was ailing when Davidson checked her May 8, and died May 9.

An orphaned bear cub now has a feisty and loving foster mother.

The head of Louisiana's large carnivore program says she was able to leave the cub with a new family Saturday in the Tensas (TEN-saw) River National Wildlife Refuge.

Maria Davidson says most Louisiana black bear females will move off when people approach. But she says that when she and another biologist tried to microchip this female's cubs, the bear made several "bluff charges" to run them off.

They left the orphaned cub in the den, then watched from a safe distance.

Davidson says that within 30 minutes, the female had moved all three cubs to a new den.

The orphaned cub's mother was ailing when Davidson checked her May 8, and died May 9.
