Do you like snakes? If yes then this video is a must see for you.
I have included information throughout, but here is a brief description of events.
I always take my Canon SLR and video camera while surveying as I like to record my sightings in this way as well as by notes. On this occasion I decided to film this male adder as he was preparing to slough (shed his skin) and when they are in this state, it is easier to get close up footage. However, what I didn't anticipate is that he would actually approach me and as I was lying on the ground, supporting my camera with my elbows on the ground, I had to make a hasty retreat!
Basically his vision was impaired and he probably picked up on the heat coming from my camera and my hands.
Anyway, watch the video and let me know what you think.
