I was birding in Thailand in the Khao Yai National Park. One day I went of the main track to see what birds I could find, on this occasion I was watching a woodpecker which are my favourite birds. I was there quite a while tapping a stick on a tree trying to bring the woody I was watching closer to me as it was quite deep in the forest.
The time came to move on and as I turned I was confronted with a Dhole who was walking up the track towards me, he was completely unaware of my presence until he was within five meters of me, at which point he was startled by seeing me there, he growled and then preceded to walk around me and carry on up the track.
I felt that because I was so relaxed and in peripheral vision that when I too was startled by the Dhole's presence that my energy changed and that's when he became aware of my presence. It was an amazing experience to be so close to a wild dog.
