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.
Here is my opinion. I realize it was not requested.
Tigers aren't all that interested on fighting.... unless of course it is for mating rights with another tiger etc.
Like Peter said, if an interaction (attempt at predation or usurping a food source) goes bad... the tiger might just take off and look for something easier.
If that is losing, then I would imagine the tiger often times loses.
With that being said, I also suspect that with the proper element of surprise... a tiger can predate a pretty good sized bear.
