So, they do measured Ustad, the problem is which are its measurements, are they going to publish them?

Hey Guate nice to meet you! I just wanted to know if the tigers from Hewett 1938 were adjusted or not. The book said the animals were measured after they gorged themselves on a kill and there is no way to guess how much weight did the kill added to the normal weight of those tigers. Still, if they were adjusted please let me know with a proof.

Rather small sized (height/length wise) male tiger translocated from Corbett to Rajaji 

Age - 6 years

Headbody length = 67 inches / 170.18 cms
Total length = 8 ft 9 inches / 266.7 cms
Shoulder height (extended paw) = 38 inches / 96.52 cms ;; (subtracting the paw length) = 81.28 cms
Weight = 215 kgs

Very heavy for his body dimensions though Reply

yea i'm thinking the same he has the dimensions of a tigress. Reply

I was also surprised for his weight for the dimensions he has. Just a guess from my side, there could be some mistake in his age. Maybe he had some more room to grow, who knows.170 cms is undoubtedly tigress category and ~7 cms less than sunderban tigers, somewhat seems impossible for a 215 kg tiger

Edit - At 3:42 the guy actually said "aur lamba hoga" meaning "he will grow more", so they probably gauged his age wrong

Another thing, perfectly shaped ridges can be seen on the canines (seen in subadults / young adults), which gets rounded off in adults.

And, I subtracted the paw pad length from the total shoulder height to get a tentative standing height.
38 inches - 6 inches = 32 inches / 81.28 cms

81.28 cms, that is too short for an adult tiger, even tigress are taller by 7 cms. Reply

172.45 kg Young Bengal male on empty stomach rescued from Abandoned Rubber Factory in Bareilly.

https://www.wti.org.in/news/wti-and-up-f...-bareilly/

Although injured, the tiger did not attack any human and was surviving on natural prey in and around the rubber factory.

The tunnel was located inside a 50×20 foot room with old power panels on the inside perimeter. Yesterday, when the tiger was finally visible during the day, the team attempted to tranquillise it, which initially proved difficult. “The tiger was wary and slightly agitated due to the presence of humans, which made the operation very challenging. Three doses of darts had to be shot to completely sedate the animal”, said WTI Veterinarian Dr Reetika Maheshwari, who successfully tranquillised the animal at around 2.00pm.

The young male had injured right forelimb.

Due to the injuries he was taken to a zoo.

Given its injuries, the tiger’s immediate release back into the wild could not be recommended, and it was decided that the animal would be moved to Kanpur zoo for further assessment. “Although injured, the tiger did not attack any human and was surviving on natural prey in and around the rubber factory. Such cases outline the behaviour of these elusive big cats who try to avoid encounters with humans as far as possible” said Dr Chatterjee.

WTI operates two Rapid Response Teams and a long-term project, the Terai Tiger Project (with support from the Uttar Pradesh Forest Department and the US Fish and Wildlife Service), to mitigate conflict between humans and big cats in the Dudhwa-Pilibhit landscape. Since 2009, the project team has rescued nine tigers from 37 human-tiger conflict situations, with four tigers successfully released back into the wild.

Hi Pckts, you remember me? I am the guy who publishes size comparisons and who sent the image of the 103 kg leopard.
I wanted to ask you a question. Many sites saybthat bengal tigers average 226 kgs while others say that males average 235 kgs and that  as example, Kaziranga Bengal tigers average around 250 kgs because of high prey presence and conservation efforts.

Which of these is true? And also, about siberian tigers, is it true that today they average only 174-203 kgs and that an amur tiger above 220 kg is rare? Are bengal tigers the biggest today? Reply

"Bengal" is a very broad term.
Depending on the location, Bengals can be different sizes but generally an average male from C/S India will be between 185kg-220kg with larger males being 225kg plus. 
Also depending on if the animal is empty or not will make a difference too.

Kaziranga males haven't been weighed so we can only make estimates but my opinion is that they're probably the heaviest Tigers alive today with Terai Boys in the mix too. 
Amurs are smaller today but it's a very minimal data base, I have little doubt that if we'd have more weights to go off of I'm sure they'd have some larger weights. If their captive genes are anything to go off of then I'm sure wild ones can still get large too. 
In terms of weight, Bengals are the largest Tigers alive today.


Hope this helps Reply

Thank you! So I musn't trust Wikipedia that says they average from 227 to 235 kg.

Thanks for the information Reply

Thanks for the information

235 kg came from a sample in Terai, it is real and reliable data (the animals were later adjusted and bit less than 235 kg)

But discussion about adjusting is useless as a large portion of food eaten is assimilated into body, thanks to high metabolism of felines. So adjusting is okay to be done only if the animal was captured right after eating.

Looking at data from scientific sources/modern sources with age of the animals known, average was 220 kg Reply

A 3 years old male Amur tiger, was caught in the Pozharsky District, Primorsky Territory, last Sunday (07/03/2021), an extremely undersized young specimen, which weighed 110 kg, veterinarians mentioned that it can gain up to 20 kg of weight when recovering, I do not know the measurements regarding its body size.

So more than half of all lions in the world exist there, compare that to of 3,000 total tigers left in the wild and most likely less than that in india. From a scientific standpoint I get what you're saying but from a practical standpoint, the reserves are massive, they can easily sustain more tigers and we really only know about a fraction of the tigers that live there, so I certainly wouldn't say they live in small isolated reserves.

Camera traps are fantastic tools but they too aren't with out flaws, many animals have learned to avoid them and even the ones they use in Kanha are few and far between, usually in areas where tiger traffic is well known and easily accessible to humans. The forest of Kanha and Pench have many terrains and the higher you go the harder it is to trek obviously but that doesn't mean that it's hard for the tiger, tigers are as dense there as they are in other areas of the same reserve we just don't get to see them as often.

I agree that young or weak tigers are pushed to the fringes, but the area between prime habitat and the fringes are massive, at least the areas I saw. This is of course, to the naked eye. In terms of conservation, the amount of area they have left isn't satisfactory, they need more, much more. But if we were to sustain their existing territory from here on out and turn up our poaching patrol and destroy the wild animal trade, stop our intrusion into their remaining habitat, there is no reason that the remaining protected areas couldn't sustain a large and satisfactory ecosystem for the rest of time IMO.

I agree 100% with your assessment on dosage, you're the absolute expert and I differ to your expertise and enjoy your posts whenever you decide to do so.
@Dr panther

Nothing would please me more than having tigers fill all possible habitat and build up a robust population ensuring genetic enrichment and the future of the species, however your "optimism" is not shared by tiger biologists or all tiger conservation specialists, we need to consider the following:

* The Central Indian landscape is a promising habitat with several TCAs ( Tiger Conservation Areas)

* Tigers like all solitary large carnivores need massive territories a 1000 square kilometer reserve would provide space for about 100 adult tigers ( space wise)

* Tigers also need sufficient prey base ...an empty forest may have enough space but what would tigers eat? They can't live on muntjac, monkeys, and rodents. The Russian far east forests have enough undisturbed space but barely any prey ( tiger density less than 1/100 square kilometers) , In Sumatra, Malaysia, and Thailand there are massive protected areas but then again not enough prey ( tiger densities 1 to 4 tigers/100 square kilometers ) ..we need to build up the prey base and conserve it to protect tigers ( food wise).

* India has 1.2 billion people more than the population of any continent except Asia , hundreds of millions of Indians live in rural areas and are poor, their livelihoods may depend on resources in tiger habitat and the conflict seems inevitable, the lessons of Panna and Sariska were very painful ( where poachers wiped out the tigers there and we needed to re-introduce them ) active anti-poaching effort is crucially important.

hello，can you tell me how big is the biggest female tiger in history，include weight,shoulder height and total length，thank you. Reply
