Where is the biggest bengal tigers?

[Ashutosh]

Two issues need to be cleared up first. When talking about “bigger” tiger, are we talking about in average or exceptional specimens.

Secondly, casual wildlife enthusiasts who have seen wildlife in both landscapes can only go on the handful of tigers they see, so it may not be an accurate reflection of the entire park base. But, hypothetically, if Rabin Sharma of Kaziranga was to go to Dudhwa for a year and study the tigers there, his word on their size difference would carry far more weightage. Afterall, he has probably seen most of the tigers in Kaziranga and he can generalise their average size and identify the biggest specimen much easily and more accurately than most people (even naturalists).

I mean, even with all the tourists going into these parks, we have photographic records of maybe 35% of individuals living in landscapes such as Kaziranga (and that is being generous), it would be higher for other reserves. Tourists go weeks without a tiger sighting in Kaziranga (there is a board at the park gate which tells you the number of days since the last tiger sighting, even in peak tourist season it can reach a couple of weeks). 

Other than that, you do what we do. Compare camera traps and images from different sources with different lighting, distance, angle and make educated speculations (of course without being delusional and hyperbolic). Reply
