Orphan bears released into the wild after survival training

'Survival school' for orphaned bears

taught these cubs how to live in the wild

Location: Florina, Greece

Bradley and Cooper were trained at a sanctuary

on how to find food and make a nest for winter

before being released into the forest

They were rescued at just four months old

because it was too late to

re-unite them with their mother

(SOUNDBITE) (Greek) ARCTUROS CARETAKER MELINA AVGERINOU SAYING:

"It is sad that they do not have the possibility to grow up with their mother because that is what is really important, for them to be where they belong. But on the other hand from the moment that we know this program works it is an opportunity to offer them a second chance, because otherwise they would have been condemned to die."

The cubs will be tracked in their new surroundings

to ensure they avoid populated areas

If they do not adapt in the wild

they will return to the sanctuary
