On the tiger-vs-bear issue, I think you have hit the nail several times here. I still think that normally, males will avoid each other, but like the accounts of Jankoskii and Kaplanov stated, sometimes they do fight and tigers are able to win.

However, it also suggest that tigers need to have some "parity" on the size issue. The large bear killed was probably no less than 300 kg, and we know that they reach up to 320 kg in the Ussuri region. However, the tiger was possibly also no less than 300 kg, according with Jankovski, so the close the weight, more advantage to the tiger.

I also have another case of a tigress killing two bears, here is the table:

The document is a thesis of Dr Clayton Miller (see the attached file) and he has published other two documents born from this thesis. The tigress that killed those two bears (Pt99) was a 6-8 years old female of 130 kg. Again, it seems that size parity seems to support tiger victory.
 

 

Many thanks for the correction on Schleyer, Guate. These long posts require a lot of time. I guess I was tired. My post has been edited already. 

The document you attached is very interesting. It definitely is the end of the assumption only male Amur tigers hunt bears, as many have stated. Tigresses could be just as active.  

I've 4 questions:

1 - The weights at the top of the table you posted. My guess is they are average weights for the animals mentioned. If not, is anything known on the actual weight of the male wild boars and the female brown bear the tigress killed? Are they sure the animals were adults? 

2 - Isn't 'Christina' the tigress who attacked a hunter after she'd been shot and wounded? If so, she made a splendid recovery.

3 - Is 'Christina' the heaviest tigress on record? I thought there was only one other tigress of 130 kg. ('Maria Ivanova').

4 - A few years ago, Miquelle said they were working on a new document on Amur tigers. That document would have new information on (the size of) the Amur tigers captured in recent years. So far, I didn't see anything. Did I miss something? If nothing, as I suspect, was published, would you be so kind as to contact Miquelle? Reply
