The friendly Chironius

One day while walking back from a transect at Refugio Amazonas I spotted the long form of this Whip-snake (Chironius sp) on the path. It was still. I only had my 300mm lens with me, the non-stabilized version at the time. So I sat down on the trail and tried to balance myself as best as possible, allowing some close up face shots of this 1.5m long snake. Eventually, it started coming towards me and made its way all the way onto my legs before realising something was wrong (it was too close to take photos by then!). It then puffed itself up and nervously made its way off the trail in the opposite direction.
