This is the adorable moment two bear cubs learn to climb a tree as their proud mother watches just days after they emerged from hibernation. The footage shows the young bears playing with each other and learning to climb a tree in the Bieszczady Mountains, near the village of Baligrod in south-eastern Poland's Subcarpathian Voivodeship region on March 31. They were filmed by forest ranger Kazimierz Nozka from Nadlesnictwo Baligrod in the Bieszczady Mountains. Mr Nozka said the warmer weather was now bringing the bears out of their winter shelters after hibernation. This was the first time Mr Nozka had seen bear cubs playing out in the open this spring. He said: ''This was a very special moment. I feel very priveleged to have seen it.''
