Even from Terrai or Nepal one Tiger was 400 lbs and was claimed as NORMAL SIZE FOR A MALE. (Probably he mean the dimensions). About the weight of male Bengal tigers: I have the book of Mazák, the reprint of 2013 of the edition of 1983, and also we have the document of 1981 for the American Society of Mammalogists. In page 144 Mazák says that the weight of the male Bengal tiger range between 200 to 220 kg and reach a maximum of 258 kg based in Hewett. In page 188 and 189 he mention that Brander says that the average weight was of 190 kg, so Mazák do not presented that average, he just quote it with its source. In the document of 1981 he presents a range between 180 to 258 kg for adult Bengals. This is the information from Mazák, based in captive specimens and hunting records. Since 1973 tiger were captured by scientists in Nepal and the range for the adult males is from 200 to 272 kg+, while the subadults males weight between 125 to 216 kg. Only 3 adult males were captured between 1970 to 1980 and the smallest one was of 200 kg (M-102). The male of 180 kg reported by Mishra is not an adult tiger as it was captured in 1980 and was included in the table of the document of Smith et al. (1983) and as you already know, no adult male captured in Nepal weighed less than 200 kg. Certainly when he says "normal size" was regarding the body size and not the weight. It is known that subadult males already reach the length and in some exceptional cases even the weight of the smallest adults, the male M-123 is a good example as it even had a territory until it was killed by the giant male M-126. The male M-104 was a subadult of 159 kg but that already had a length of 289 cm. Dr Karanth (2003 and 2013) stablished a weight between 175 to 260 kg, but that range is for tigers in the Southeast of Asia (he included all Indochina) and not only India/Nepal region. Dr Sunquist (2010) stablish a range between 200 - 260 kg for adult males from India and Nepal. Finally Dr Jhala presented an excelent study about how to age a tiger and he establish that males of over 3 years, which are young adults to 5 years weight between 200 to 260 kg. That do not means that smaller males do not happen, but it seems that the norm is that range. Now, we need to take in count that some males were baited, like the 200 kg male M-102, so if we adjust it for stomach content, this male could had weighed as low as 181 kg. However from 16 adult males captured by scientists, only 4 males weighed less than 200 kg, two were young adults (183 kg and 185 kg), other was an old one (197 kg) and a last one was a young male that was injured (197 kg). So, while the overall average of the Bengal tiger in mainland, using both scientific and huting records, provide a figure of 210 kg (n=160; range: 150 - 272 kg), IF we use only scientific records the average weight will be of 220 kg (n=16; range: 183 - 261 kg). Take in count that the figure from scientific records is fully adjusted for stomach content and include only specimens of over 3 years old (not fully adult but already sexually mature), which suggest that all the males between 150 - 180 included in the hunting records were not adults at all and that the figure of 210 kg is an underestimation. Check these images for more details and take in count that many posters had provided more weights in this topic of male tigers that I did not included yet as I want to corroborate them, and if we include them probably the average of 220 kg will increase:  *This image is copyright of its original author  *This image is copyright of its original author

I am wasting to much time with you and your crazy conclutions. If you try to prove that lions are bigger or if you try to create problems trying to drag the "vs" debate to this forum, you are wasting your time. 
Just FYI any comparison posts here will be deleted. There's seperate thread for that.

Other datas are only reports and datas with small sampe sizes. M8 personal opinions are not facts. WII may not released the data in public, but their sample size is in thousands... You'd know that if you were familiar with their extent of fieldwork. It dwarfs any personal venture of any independent scientist. Guys like Yadavendra Jhala or Wasif Jamshed who represent them & speaks based on that data. If you take my advice & check old posts, you'll see here alone we have more than hundred animal's data (mostly dead, captured or translocated) from just news in past few year. And for majority cases we only have photos of the animals being weighed but couldn't find which WII representative had the data. (09-25-2020, 10:38 AM)GuateGojira Wrote: Why are you challenge me? What is your porpuse here? Who send you? He seems to be claiming something like equal weight individuals of both species don't have of equal size & dimensions... Also that you're overestimating by taking into account newer sources instead of only 50-year-old ones.

I don´t think, that at this point guate has any need to prove something, when you haven´t been able to explain what would be really wrong in his charts. 
I am sure a lot of things will change if some expert from WII publishes data regarding tigers, like YV Jhala's data (from which he concludes adult males are 200-260kgs). No one possesses more extensive database than the National Institution.
I joined SCI and now have access to their Record Books.

Weight 400-575 pounds (181-261 kg). The female is about one foot shorter and weighs 220-350 pounds (100-159 kg). A large, long-bodied, long-legged tiger. Except for the cheek ruff, the coat is uniformly short and glossy. General color is rich orange or rufous-fawn, typically with 18-20 black stripes-often doubled-from shoulder to root of tail. DISTRIBUTION Formerly from the Indus River valley in Pakistan to the Irrawaddy River valley in western Myanmar (Burma). Extinct in Pakistan by 1906, but still found in most of the rest of its geographical range; however, its actual distribution within this range is substantially lessened. STATUS The 1993 census estimates a total of 4,500 Bengal tigers, with about 3,750 in India, 250 in Nepal, and the rest in Bhutan, Bangladesh, and western Myanmar (Burma). Sumatran Tiger Only 4 Available 1. 09/1970 Indonesia, Padang Betua Alam Shah R 22 4/16" 1 1 2. 07/1992 Indonesia U 22" 3. 11/1993 Indonesia U 20" 4. 04/1968 Indonesia, Palambang Barat Dollah R 19 3/16" 2 2 DESCRIPTION The smallest surviving tiger. (male) Length, including tail, up to about 7'10" (2.4 m). Weight 220-310 pounds (100-140 kg). Females are shorter and weigh 165-240 pounds (75-109 kg). Much smaller than the Bengal tiger, with the stripes closer together, sometimes degenerating into rows of small spots. The cheek hair is long, and there is usually a short neck mane. The white of the belly is limited to a narrow striped area, and the light color encircling the eyes is smaller than in mainland races. The forelegs have striking black markings on their inner and hind parts. The skull is said to be typically flatter. DISTRIBUTION Only on the island of Sumatra in Indonesia, where it is found mainly in the north and in the mountains of the southwest. TAXONOMIC NOTES DNA studies in 1998 indicate that the Sumatran tiger may be a separate species from other tigers. Joel Cracraft, of the American Museum of Natural History, believes it probably became isolated from other tigers between 6,000 and 12,000 years ago, allowing it to evolve differently. STATUS Until recently, openly hunted as vermin by local residents, with skins marketed in Singapore. Wild populations have declined from about 1,000 in the 1970s to 500-600 at present, with another 235 in captive breeding programs. 
According to the Photographer of this tiger, he told me this tiger weighs over 230 kgs...
