What sort of temperament personality did Tasmanian tigers have?

Answer 1

This isn't known with any certainty. There was very little study of the animal in life and the vast majority of what there was was undertaken with captive specimens. Naturally this gave little indication of how a wild animal might have behaved.

Also in the latter years of human contact with the species they were subject to an as yet unclassified but virulent disease, which spread through and devastated both the captive and wild populations. Which, it has been suggested, may have had a profound effect on the animal's behavior. For example leaving them weakened and less vigorous than a healthy animal might be. It has been suggested that the often repeated anecdotes about thylacines giving up or even dying almost immediately on capture, stem from encounters with affected individuals, again giving a distorted picture of their behavior.

There is of course anecdotal evidence from the bushmen and trappers who witnessed the animals in the wild, though it is contradictory. It has variously portrayed the animal as being very wary to extremely bold, and from relatively placid to highly aggressive. Amongst this though there does seem to be a fairly consistent trend suggesting that on capture the thylacine was fairly easy to handle.

Sadly with the almost certain loss of the species and of those who experienced it first hand, that's about all we're ever likely to know.
