Modern weights and measurements on wild tigers

 sid_dtr when caught he was over 250 kg as per first hand information shared by a very reliable source i cant name 
Dudhwa, what a disaster. catching the wrong tiger and keeping him captive for this long. bs park management. they need to learn from their neighbors on the other side of the border. Also, I think the source is most likely Dr Parag Nigam. he was involved with this male tiger’s physical assessments.
@Roflcopters, Dudhwa doesn’t have a rehabilitation centre like most of the central Indian parks (the construction is ongoing). I am guessing once they realized that this wasn’t the tiger they were looking for, they thought might as well take him to Lucknow zoo and collar him and get his measurements without immobilization as those are very tricky to do in Terai habitats in the open.
So, it took nearly a week for his release. Meanwhile, they actually caught the tigress who had killed many people and as it turns out was the wrongly captured male’s mate. Apparently, she even visited him when he was in the cage. She has been brought to Lucknow zoo as well.
yeah i have been following this case since the operation began, it’s just sad that an innocent tiger was caught and held captive for so long. Dudhwa, Pilibhit and all these adjacent parks need a proper rehabilitation facility as well as trained vets that can handle these situations in the most professional and timely manner.

Having it would be very helpful for me. It's not from me, it's Siddharth Singh who I quoted. He's a guide out of Dudhwa  (07-02-2022, 02:35 AM)GuateGojira Wrote:Hi Guate,(07-01-2022, 10:14 PM)LonePredator Wrote: Hello @GuateGojira, could you tell at which locations were the top 5 heaviest Amur Tiger specimens found? Including the reliable 300kg ones and also the 254kg one. Are the tiger actually considered into two subspecies (Panthera Tigris Tigris on the mainland and Panthera Tigris Sondaica on the islands) or are they distributed into 5/6 subspecies? I'm asking because I've read many papers that had opposing views.  (07-12-2022, 02:13 PM)acutidens150 Wrote: Hi Guate, At this moment there is not a consensus. The Cat Specialist Group from the IUCN says that tigers are separated in two subspecies, however they also accepted that there is no concensus as some scientists support the view of more subspecies (Kitchener et al., 2017). Latter Liu et al. (2018) provided genetic evidence that it could be at least 5 subspecies of tigers at this moment. Please check this link: https://wildfact.com/forum/topic-modern-...rs?page=58 There, in posts 863 and 864 a made a long analisys about the issues with the clasification of the subspecies of tigers and I reached to two conclutions: * What means to have only two subspecies? It means that we can use Indian tigers to repopulate Indochina, Malaysia and South China. Also provides "value" to the mix captive tigers that populate USA and other countries. While the idea will be good, actually it will create a mess if is not correctly used. For example, most of the captive tigers are a mix between Amur and Bengal tigers, and if we remember, these two populations are the most diverged since the Pleistocene and even under the new clasification they belong to two different conservation units, so the large captive tigers of USA are STILL useless for conservation, but I highly doubth that those places that breed tigers for business are going to check and accept these details from the study. Other thing is that there is still a good and viable population of Indochina tigers in Thailand, so there is no point in trying to use Bengal tigers to populated Laos, Vietnam and Cambodia, while the efforts should be focused in increase and care the tigers from Thailand and, with time, used them to repopulate the other Indochina countries. As we can see, the idea of two tiger subspecies could be the correct one, but sadly is the most problematic based in political and economic purposes.  *This image is copyright of its original author * What means to have 5/6 subspecies? It means to continue with the effrorts to save the tigers like they are in this moment, each country manage they own populations and keep the "purity" of they specimens. Captive tigers in managed zoos still have they value and the mix tigers from private owners can't be used for breeding which is good! So, the "5/6 subspecies" scenario could not be realistic in a natural point of view, but is the most realistic in the modern days, based in the current distribution of tigers and will keep the traffic of generic tigers at minimum.  *This image is copyright of its original author Using all this information, my opinion is that 2 tiger subspecies is the real one, but for the management of the modern tiger populations and to avoid traffic and bussines of "paper" tigers, I think that the best is the usage of the 5/6 subspecies scenario. Hope this helps.  
Some large tigers of 21st century.
Over the past year and a half, me as well as others have communicated with many scientists and forest officials from India and nearby countries. A large database for weights of Bengal Tigers has been compiled. Here, I am going to list and make remarks on some of these large tigers that have been documented by scientists and researchers and I have permission to talk about freely. Some of these have been confirmed twice. I will not add direct names of sources to avoid spam. *(+) sign - exceeded / more than Following is the list in ascending order: 1. M-125 aka "Madla" Weight: Exceeded 250 kg scale (adjusted minimum 220-230 kg+) Age: 8 - 8.5 Capture date: 12-01-2002 Location: Panna Tiger Reserve Region: Central India Remarks: Madla exceeded a scale of 250 kg used by Dr. Raghunandan Chundawat. This included around 10 kg weighing bed and est. 20 - 30 kg food. Minimum empty was estimated to be no less than 220 - 230 kg+ 2. T-3 aka "Betal" Weight: 240 kg Age: 10 Capture date: 13-01-2013 Location: Panna Tiger Reserve Region: Central India Remarks: This tiger was captured multiple times. The weight was confirmed by Head of Forest Department in an email. 3. M-91 aka "Old King" Weight: Exceeded 250 kg scale (adjusted 240 kg+) Age: 6 - 6.5 Capture date: 11-04-1996 Location: Panna Tiger Reserve Region: Central India Remarks: After recovering, he regurgitated the food he had eaten before being darted. To eyes, M-91 appeared fully gorged with 25 - 30 kg meat but the amount in vomit was only 19 kg thus adjusted to 240 kg+ empty 4. MT-3 Weight: 243 kg Age: 4 Capture date: March of 2020 Location: Mukundra Tiger Reserve Region: Central-Western India Remarks: Originally from Ranthambore, he was darted after a maggot infection in his face which hindered him from hunting. A few months later, he died due to illness and it was found he lost over 52 kg in this period. 5. T-04 aka "Mara" Weight: 250 kg (empty or near empty?) Age: 2 - 3 Capture date: 29-01-1990 Location: Nagarahole National Park Region: Southern India Remarks: A young tiger that was attracted to bait but captured within 10 mins of taking it. 6. Unknown Weight: 250 kg empty Age: Adult Capture date: 2008 Location: Tezpur (near Kaziranga) Region: North-Eastern India Remarks: A very large (long and tall) tiger that was rescued after being stuck in a well after annual floods in the region. 7. Unknown Weight: 250 kg empty Age: Adult Capture date: 17-06-2021 Location: Valmiki Tiger Reserve Region: Terai Arc Remarks: This problem tiger was causing chaos in a village near Valmiki Tiger Reserve. He was said to be hungry for 4-5 days 8. Unknown Weight: 250 kg+ Age: 6 - 7 Capture date: 28-06-2022 Location: Dudhwa Tiger Reserve Region: Terai Arc Remarks: This tiger was accidently captured in a trap set up for another tiger. A "highly reliable" source confirmed this tiger weighed more than 250 kg. 9. T-24 aka "Ustad" Weight: 240 kg / 258 kg empty Age: 3 / 9 Capture date: 2009 / 16-05-2015 Location: Ranthambore National Park Region: Central - Western India Remarks: Ustad was moved to zoo for alleged attacks on humans. 10. "Poochkata" Weight: 285 kg gorged (adjusted 255 kg) Age: Adult Capture date: Unknown Location: Kanha Tiger Reserve Region: Central India Remarks: Weighed by Dr. Jhala of Wildlife Institute of India. He was gorged at the time of capture so adjusted value for 30 kg meat, resulting in c. 255 kg empty. 11. Unknown Weight: 260 kg Age: Adult Capture date: Unknown Location: Unknown Region: Central India Remarks: In the paper, "Field Guide for Ageing Tigers" by Dr. Jhala, a range of adult tiger weights is given as 200 - 260 kg and Dr. Jhala's unpublished data is quoted. This leads me to believe that this 260 kg tiger is an individual tiger, although I could be wrong. 12. Unknown Weight: 280 kg (adjusted 260 kg) Age: Adult Capture date: Unknown Location: Ranthambore National Park Region: Central-Western India Remarks: Large tiger that had recently eaten before being weighed. So adjusted value for 20 kg meat, resulting in c. 260 kg empty. 13. Unknown Weight: 280 kg (adjusted 270 - 280 kg) Age: Could be a young adult or adult Capture date: Unknown Location: - Region: Central India Remarks: The source could not comment on if the tiger was empty but confirmed that it was 100% not gorged, meaning the tiger had nothing noticeable amount food in him (little to non). Hence I adjust for 10 kg or less than 10 kg food, resulting in c. 270 kg+ empty, making him one of the biggest felids. 14. M-126 Weight: Exceeded scale of 272 kg Age: Adult Capture date: 1984 Location: Chitwan National Park Region: Terai Arc Remarks: A large tiger captured by Dr. Dinerstein and his team in 1984. The tiger exceeded a weighing scale of 272 kg. 15. M-105 aka "Sauraha" Weight: Exceeded scale of 272 kg Age: 11 Capture date: 1980 Location: Chitwan National Park Region: Terai Arc Remarks: One of the largest tigers of all time, Sauraha exceeded a scale of 272 kg on his 4th capture. As the researchers who captured him described, he was a walking hunk of rippling muscle without an ounce of fat. (07-13-2022, 01:18 AM)Khan85 Wrote: Some large tigers of 21st century. Good list, I’d be curious on a few where you got the information from other than the obvious ones we know about. Also missing quite a few modern day weights, these were just the heaviest ones you know about I’m assuming? 
That's a great compilation @Khan85 . But I wish to see the source of 13th specimen mentioned over there. Is that the alleged maneater from Ghunghuti forest ?
@Jerricson
here’s the source https://wap.business-standard.com/article-amp/pti-stories/tiger-which-terrorised-people-around-ghunghuti-range-caught-116112101395_1.html @"Khan85" Ghunghuti male tiger’s capture date was either November/19/2016 or November/20/2016 based on the original article and the location was ghunghuti range.
@Pckts Thanks. You are correct, this is a list of big tigers only. You may PM me if you want information about any tiger.
@Jerricson @Roflcopters The tiger mentioned in the list is not the one from Ghunguti. I haven't added the Ghunguti tiger yet as we need more information about it. |
