I don't understand

The problem is very likely money. It takes people being interested enough to finance a scientific study in the field. I would imagine that a tiger would be more than difficult to track. But what if a big male grizzly was darted and tagged with a tracking device? Then, expert trackers could trail behind the bear at a safe distance. Of course, we are talking about a black grizzly living within an Amur tiger's hunting range. With a bit of luck, they might discover when the bear scavenges a tiger kill or possibly where the bear displaces a tiger from a carcass. Evidence of any interaction might, with a lot of luck involved, be discovered. Such a study would be difficult, but not impossible.
I would not be surprised that some day we find that Russia has made such studies.   Reply
