Though all the windows were fogged due to the low outdoor temperatures I was able to shoot some footage of the polar bears. The polar bear twins, born on 9 December 2013, still love to play with mum two years later as you can see. Nevertheless they are about to leave their birthplace, because competition (for food) between the siblings is expected soon. The father of the twins is living in the adjacent enclosure to make sure he doesn't hurt his offspring. A father bear presents a threat to his cubs, as he may see them as potential prey and could even eat them.
