It was barely a stone&rsquos throw away from the southern boundary of Corbett. Tigers frequently crossed over from one side of the river to another, so when a cheetal called to warn its fellow jungle denizens of a tiger on the prowl, we were not surprised. Judging by the definition of the call, the deer was an estimated fifty meters away from us. Born and brought up in the jungles of Corbett, Usman, our driver and guide, felt that the big cat was too far away to pose a risk of any sort. Our work continued without much ado until the cheetal called once again. The call was louder, more distinct and came from a forested trail leading off from the other end of the bridge. This could mean only one thing, the tiger was on the move and it was headed towards the bridge.
