Seeing Muna, the tiger with CAT written on his forehead, come out of the bush at Kanha, and wander along the road beside us, mark his territory, walk on a bit further then cross the road. All this whilst about 12 jeeps were jostling to get close to him. He didn't pay us the slightestbit of attention.
Seeing how the wardens reacted at Bandhavgahr when we reported seeing the tiger with the porcupine quill up its nose on our last day. Within hours they had got a vet to the tiger, darted her, and removed the quill, which was so far up her nose it was life-threatening. She was in agony and it was very heartening that they intervened so quickly.
Seeing two wild dogs bring down an 8-pointer spotted deer stag. They had obviously been attacking it for some time and the stag had much of its rump eaten away. Every time they brought it down it got back up to fight again even though it was deeply in shock. Finally they left to get the rest of the pack, and even then it tried to get away, but was far too badly mauled to survive. It was a very brave animal.
