There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.
I have been waiting for a very long time before really viewing a video showing a lone tiger, Raja according to what you said, killing an adult gaur. Before it I really doubted than a lone tiger could achieve that. As you said this is much more difficult to watching and filming such a fact than the same facts as concerns lions in afican savannah. And we can add that the tigers are, in my opinion, more discreet than lions, than prides of lions.
Of course I cannot judge the health of the gaur killed by Raja. Nevertheless I was amazed to note how easily the tiger seemed to master the gaur's reaction defenses. More easily than a male lion killing a lone buffalo, for exemple in the movies posted by Lionness, without forgetting the gaur's weight being bigger than the african buffalo's one. Perhaps too, on the other hand, the african buffalos protect oneself more vigorously against the lions. But, of course, I cannot be categorical after having seen an only one or two videos showing a tiger killing an adult gaur. We cannot be categorical after so few examples.
