There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future.

Thank you for showing interest in my research. The weight of Bengal tigers varied from 200 - 280 kg (adult males, however, there are exceptions) & 110 - 180 kg (adult females in general). Ranthambore tigers were one of the largest amongst the tigers my PhD supervisor caught for collaring.

This gives a really good insight about tigers captured in India. 

Here's what I make of this - 

1. Researchers consider the normal range as 200 to 280 kg
2. Tigers below 200 kg and above 280 kg are considered exceptions
3. Tigers larger than 280 kg have been captured


Pls PM me if you wish to know who was the researcher...
Some more info about this 280 kg bengal tiger. 
He was neither empty nor gorged when weighed. 

Also I was able to communicate with a researcher who had a sample of 8/9 wild amur tigers averaging 206 kg and the largest amur was larger than the largest previously recorded in zoological literature (212 kg).
Is there information specific about those Siberian tigers and their weight?

Is that a different tiger from the one mentioned in this old email?

https://wildfact.com/forum/topic-on-the-edge-of-extinction-a-the-tiger-panthera-tigris?pid=99474#pid99474
yeah, that tiger was 285 kg and gorged when weighed
Have you found the identify of this kanha tiger?

Good work, Khan! 

Can you post this info in the tiger extinction thread and in the Amur tiger thread? This in order to prevent our members and readers from time-consuming quests. Try to be as specific as possible. The more we know, the better.  

Our member 'Betty' sent me reliable information about the size (length and weight) of captive Amur tigers in a large Chinese facility (tiger park) today and I nearly finished a table with information about the size of captive Amur tigers. We're talking about very decent samples. Both tables will be posted in the tiger extinction thread soon. I might post a few copies in the captive lion and tiger thread as well.

Weights of modern tigers - Updated

Here is an updated list of the modern records of tigers. It includes only males over 3 years old (classified as adults). This table still don't include the male of 1|70 kg from Malaysia (yet to confirm) but did include the other 5 males reported to other posters here, even the male of 285 kg gorged (I put it at 250+ kg "empty" but could be heavier).

IMAGE UPDATED

IMAGE UPDATED

Save it for your records and if new information is available, I will update the tables again.

Greetings and cheers.

@GuateGojira  @peter  Thanks to @Rage2277  for first bringing this study to my notice. 


Here you can find very detailed measurements on 38 bengal tigers (11 males + 19 females) along with age - growth curve chart, collared in Panna and some other National Parks. 

https://www.pannatigerreserve.in/BOOKLET%20ON%20TIGER%20BODY%20GROWTH%20.pdf

Remarks about the biggest male 
I think that P-111  is the biggest male tiger in the study. 

- Captured 5 times in total 


Capture 3

- Age = 5yr 6 mn
- Weight = 226.7 kg
- Head Body length = 184 cm 
- Total length = 283 cm
- Shoulder height = 127 cm
- Neck girth = 70 cm
- Chest girth = 154 cm


Capture 4 

- Age = 8yr 10 mn
- Weight = N/A
- Head Body length = 211 cm
- Total length = 311 cm
- Shoulder height = 120 cm
- Neck girth = 76 cm
- Chest girth = 154 cm


Measurements were taken in straight line, I believe (first, the length of head and then the length of body). In capture 3, his head-body length was 184 cm and total length was 283 cm at the age of 5yr 6mn. On his 4th capture, his head-body length increased to 211 cm and total length increased to 311 cm. 

Since the strongest correlation of weight is with HBL/TL, he could have been heavier than 226.7 kg on his 4th capture.

Thank you very much for this document. This will chance the tables that I made. So, wait for the update.

This is a great document, maybe in the future we could get a document like this but from the tigers from Ranthambore.

Wonder why the shoulder height was off by more than 2” on the most recent capture. Plus a 14” increase for a cat that was 5.6 years old during the first capture is too much. The protocols were probably different between the two captures would be my guess.

All measurements were taken using the same protocol as mentioned by NTCA. Also taken by the same vet so I doubt if that´s the case.

They definitely were taken differently.
Shoulder height doesn’t get shorter and not to mention his body length from his most recent capture was shorter again. *19cm shorter within a year-ish* That is definitely something that will not change no matter the age. 
Most of the time these measurements are done by teams and depending on the capture crew that team will change. Just because the same vet is on site doesn’t mean they’re taking the measurements. In fact they’re usually there to monitor vitals and distribute the correct amount of anesthesia.
Lastly, even if the same protocol is “used” doesn’t mean that the member will measure in the same way.

Even if the measuring protocol was changed or the tiger was measured by different people, there is almost no way it causes a difference of 26 cm. Looking back at tiger measurements from Cooch Behar and Hewett the difference was at most 5-7 inches / 13-18 cm when measuring between perpendiculars and over the contours. Such large difference can only be caused if they suddenly decided to use some protocol like ALPRU they did with Namibian lions. Human error can cause a difference but nothing more than a few centimetres, not nearly a foot.
