Today over in Yorkshire I spent what will likely be my last day in the field in 2013 before going back to university. The day started quite cool, foggy and damp. However, despite this a male Adder (Vipera berus) was out basking, probably because he was shedding his skin. Soon afterwards I started turning some stones looking for amphibians, but instead under one large rock I was treated to a male and female adder huddled together. After a few seconds the female started to wake and she made her way off before I had chance to replace the rock back over them. Then the male started flickering his tongue so I gently put the rock back over him before he realized what was going on. After a while it got a little warmer and I saw two different female adders out basking and later on I also saw the female that was under the stone out basking. The male was still under the large stone almost six hours later when I checked out of curiosity.
