Summary[edit] Description: English: Adder (Vipera berus) On The Track This small adder, which was sunning itself on the track, didn't hear us approach. It turned and faced us, giving just enough time to take the photograph. We let it slip away into the heather and continued our walk a few metres above the track - just to be sure!.
