Polar bear

Walker (R) the polar bear meets with new male companion Arktos at the Highland Wildlife Park on April 9, 2012 in Kingussie, Scotland. Arktos arrived from Hannover Zoo in Germany on April 4 to be a companion to the Park's resident polar bear Walker. A year older than Walker and slightly larger, Arktos is four-years-old and it's hoped that the bears will establish a relationship of friendly competitiveness.
