Amur Tigers

[Pckts]

Notice the prey size difference. All the prey hunted in the Sikhote range is pretty much smaller than any other locations posted. That might be a tell tell sign as to why siberians could be shrinking.

If we use this info above and look at the time frames.
What do you notice that was different in the 1933-48 compared to the 1994-1999?
I see a couple of things.
Looks like bears contributed more to a tigers diet as well as Moose and musk deer. It seems that tigers where forced to almost exclusively prey on elk and wild boar. With out the presence of bears and moose these tigers are starting to shrink in body mass. Reply
