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 believe the range of possibilities is very large. Of course there are some records of tigers hunting and killing some rhinos and elephants. Even if we neglect the fact that these big targeted preys were often females, or some sick and weakened individuals. When somebody such Peter tells that a wild big male boar of Amur is very difficult to hunt even for an adult tiger, I have no difficulty to believe him. Just look at the photos, big wild siberian boars are very impressive animals...
Because on the other side we can see here some videos showing the big difficulties to kill even a sambar or a chital for some adult tigers.
As Peter says the distances travelled by an Amur tiger in order to kill a prey are very long, much longer than in India for example. The felid can be tired and the only one preys it meets are the most difficult to put down (adult boars and bears in the Amur country). Thus the amur tiger are used to kill such preys, but often for killing them they are not in the best conditions (tired, weakened, starving...). In a way, it's a hunt under extreme conditions.
