The polar bear cubs that were born at Moscow’s zoo three months ago have left their lair. The little bears have spent the last few days exploring their enclosure and now play and eat in the open air.
People visiting the zoo are particularly interested in how the bears are reared. The bear cubs take walks under the watchful eyes of their mother Sima. Zoo staff say their first walks were rather short - lasting no longer than half an hour. It is warmer now and the cubs spend more time in the open air. Sima, the mother bear, entertains the audience by letting the bear cubs ride on her back and playing ball with them.
