As a tour guide of a Photographic tour group, I was heading with my tour group to Kandy, the hill capital of Sri Lanka from north, we stopped on the road side to capture the paddy fields. While taking the photos of paddy fields, I saw this Rat snake was chasing it's prey, a mouse and the mouse climbed on to a near by tree and disappeared. The snake also climbed the tree. I captured the snake as it was climbing the tree and I wanted to capture the snake with it's full toung out!
