Capture season of 2013 and the first time Brutus was weighed by onçafari and other south pantanal females.
Garoa female: Caught at 21:40 on April 14 in the trap located in a cattle carcass in the Piquete da Caixa d'agua. Young female, estimated to be 15 months old, weighed 61Kg and had a very healthy appearance. Biological materials (blood, hair and ticks) were collected. It was not equipped with radio-collar in function of its tender age, still showing signs of growth and weight gain.

NOTE: Garoa was captured once again as an adult and she weighed 83kg.
Teorema female: Captured at 4:00 a.m. on April 16th in the trap located in a cattle carcass in the Bodocó wintering. Adult female with an estimated age of 07 years, weighed 95 Kg and showed physical signs of possible pregnancy (numb breasts and distended abdomen). She was equipped with radio-collar and biological materials were collected. Later pregnancy was proven. It has been monitored since then, together with its cub, which is now seven months old.

Brutus: Captured at 8:00 p.m. on October 18 in a trap located on the Corridor of Three trail. Adult male, estimated age of 08 years, weighed 115 Kg. It was equipped with radio-collar and biological materials were collected. Its collar will provide subsidies for greater knowledge about male spatial information, given this not very well known and/or disseminated in other projects. It is being monitored since then.

Troncha female: Captured at 23:00 on October 21 in a trap located in Baiazinha Isolated. Adult female with an estimated age of 09 years, weighed 110 Kg and showed physical signs of possible pregnancy (numb breasts and distended abdomen). She was equipped with radio-collar and biological materials were collected. It has been monitored since then.

So now we all can at least assume how big a pregnant pantanal jag might get (she had a cub named Mion in 2013) But regardless of pregnancy or not Troncha was always stated as a very big female.
''When the Mamirauá Institute team found this female jaguar she was pregnant (weight 39kg, size 1m 68cm). Generally jaguars take care of their young and wait two years to mate again. However a year passed and there was Fofa with a new newborn cub. "What impressed us is that Fofa has had another cub in such a short time. This fact leads to new questions and hypotheses about the behavior of jaguars," said researcher Wezddy Del Toro.

''Django is the only black jaguar on our list. This type of fur is also rare in nature: they only exist in some types of environment and, when they occur, they represent about 10 to 20% of the jaguar population. Melanism occurs due to a genetic mutation that causes a high concentration of melanin in the animal's fur, the pigment that gives it its black color. Django is a male weighs 54kg and 1 meter and 80 centimeters long.''

"The captured jaguar was a healthy adult animal, weighing 47 kilograms. The scars on his face indicate that he probably had to face other jaguars to reproduce"
*This image is copyright of its original author
The animal was in great health conditions.
*This image is copyright of its original author
He was another male captured by Instituto Mamirauá - Projeto Iauaretê
"The result of the capture came in the loop trap. The animal a young male of 60 kg with about four years was already known by the technicians and had even earned a nickname: Sancho. Two years ago he and his brother Pança male were frequently seen on the BR-469, access road to Iguaçú Falls. Sancho was sedated and soon after was weighed, measured and examined receiving a monitoring collar.''

41kg Atlantic Forest Pança male ( he is Sancho's twin brother )
''That jaguar was very health. He weighed 41kg. His belly was so full of the easy and abundant meat of the pasture that it earned him the name of Pança at the time. "He's one of the twins", concluded the biologist Apolônio Rodrigues, director of Conservation and Management of Iguaçu. He was, therefore, one of the cubs that two months ago Apolônio photographed in daylight, on a summer emollient afternoon, eight meters away from the lodge that was hosting, at that time, more than twenty students from a German university.''
Luíza Caatinga female was in terrible conditions, she was stuck/trapped in a blocked cave for 22 days without food and water and after the rescue thanks to the Programa Amigos da Onça she regained weight which I posted with her story in full details in the Jaguars of Brazil thread.
*This image is copyright of its original author
''When she was rescued on May 3rd 2019, the jaguar that is 58 centimeters in height and 1 meter long, she was very weak, dehydrated and malnourished weighing only 35kg.
After the treatment the feline returned to her natural habitat with 46kg. she was given a monitoring collar and is accompanied by the members of the project through satellite.''
*This image is copyright of its original author
Luíza caatinga female already with 46kg and ready to return back to the wild Caatinga.
*This image is copyright of its original author
''The jaguars of the Caatinga are naturally smaller than those of other biomes as a result of an evolutionary adaptation to the vegetation and climate of the region (being smaller they need less food, less water, spend less energy and regulate the body temperature more easily).'' " They are smaller but not less strong " warns Cláudia biologist of the project. "They have an incredible surprising strength."
*This image is copyright of its original author
Despite small these beasts are incredibly powerful.
I think the Caatinga females might overlap with Caatinga males in some cases, So I am not gonna count the 46kg. 11kg weight gain cause she was treated by the Amigos da Onça project to recover her conditions.
So if Luísa caatinga female when she was malnushered, weak and dehydrated weighed 35kg, I think a healthy Luíza (on natural wild conditions) can mostly overlap with caatinga males but maybe other females might be fairly smaller than Luíza (or not). without mentioning the Caatinga Pumas that a few are similar ( some are even larger ) in sizes.
Regardless of what the truth is, its an amazing story of rescue and I hope Luíza is doing good in the wilderness of Caatinga and I know she's in good hands cause Programa Amigos da Onça is monitoring her steps.

I think Yapu was captured other times.
He must be way above that weight now, he's got an impressive build. Btw, do you have any more info on Matheus male? Last time he was weighed he was 134 kg, little is known about him.
Yeah Matheus is a hell of a beast, Unfortunatelly I don't know if he was captured once again and even if he was, it also takes the projects to reveal his weight to the public as well.
About Matheus life the only thing I know is that he took over the territory that used to be ruled by the deceased 130kg Sossego male in southern Pantanal around Fazenda Barranco Alto. Sossego was poached shot to death with bullets fractures into his skull ( one more beast lost to the poachers ). Thus letting his territory vacant which led Matheus male to take it over.

Not only those 2 were on the 130's I am sure Colombiano is way far above that range, Macho A like you said is propably near that range too and don't forget the brothers Oreia and Grandão which both are quite robust with Grandão being the larger one as his name already says ( the big one in portuguese ).
About Colombiano in that area yeah he was but south Pantanal is massive, these areas are huge. areas like Delta do Salobra got different males ( I know 2, Prainha and Neo males ) and also to the entrance of Pantanal Cáceres as you saw in the jaguars of brazil thread, that area is very near to urban area with only a lake separating them and is very unusual to see jaguars there. One male was surprisingly recently seen there, maybe that male got pushed all the way to Cárceres due to the tough competition in the central areas. So these males range a huge territory.
One example by the radio collar map Footages of the Cerrado jaguars shown by Leandro you can see that there's a moment when Rogério cerrado male left his area to find Ariane cerrado female, then Tiago cerrado male ventured into Rogério's territory while he was absent for a while then Tiago left.
I am sure with Pantanal jaguars is no different, sometimes one male is just checking up the others territory then leaves after picking up the scent of that lands ruler. back in the years when Sossego was alive he was seen in that area more common and sired cubs there with Jeffa large female and others.

you understand portuguese here's the sad news of Sossego's death. found floating on the black river without his collar.

I was thinking of doing a comprehensive list of jaguar weights provided by Oncafari and Oncas do Rio Negro (my keyboard is in English don't mind the c), to update the weights from Almeida that people always go back to get information on the average Pantanal jaguar, your knowledge and help o this would be greatly appreciated. Here are the following weights from Oncafari based on 9 males captured:
107 - Apache
120 - Brutus
138 - Felino
106,3 - Pirata
131,06 - Shaka
120 - Sombra
110 - Ziko
120 - Juru
130 - Adriano (not sure if he is tracked by Oncafari though)
Not sure if I'm missing more captured males that you can add to the list.
Based on those initial 9 males the average is 120,26 kg. Way above the supposedly 99 kg by Almeida, although his sample comprised of 24 individuals so we'll need more data to properly challenge the Almeida average. In this list I didn't include the Oncas do Rio Negro data because I'm not the most update with it.
Juru and Adriano are males from northern Pantanal though.
Sombra male on his last capture in December last year weighed 122kg. Check the link bellow.
That 120kg of Sombra male was on his prior capture in 2017. They didn't update their webpage. So let's stick with the 122kg for Sombra.
Add on your list Brazuca male 112kg and Nati male 110kg both southern pantanal males whom were collared by Onçafari project but both males didn't habituated for that long in the Caiman Ecological Refuge being monitored just out of the border probably because of the arrival of Xavier male which gave tough times to the males of the area. Xavier was no joke during his prime and its a shame he wasn't weighed.
Four more males to be added on your list are the misterious pantanal males we discussed in the jaguars of Brazil thread confirmed to be one of 130kg and the other 135kg. And also Mancha-Preta male 102kg and M&M male I saw he weights 121kg and he is monitored by Onças do Rio Negro.
About the average size due to the lack of enough infos and datas published for the public unfortunately. I still think the average Pantanal male is 105kg because for each small pantanal male of 100kg or slightly bellow, there are 3 larger ones. The Almeida's average was 90kg more than 40 years ago with jaguars on an enviornment and conditions I don't even wanna talk about, Peter Crawshaw himself knows what I am talking about cause he saw it all in person back then. They don't average 90kg anymore, NO WAY. People should bury that outdated claim nowadays once and for all.
Pantanal jaguars got the size they deserve TODAY.
you should also add Matheus 134kg and Sossego 130kg males. Onças do Rio Negro monitores both ( not Sossego anymore sadly ).
And from northern pantanal besides Juru and Adriano there's also that 148kg empty male. I think just the nowadays northern Pantanal males would be enough to TANK these outdated Almeida's weight datas, and if you add up the Southern Pantanal males it will be overkill
Too bad there are very few northern pantanal males verified, the much larger ones you'll find there.
There are more jaguars to be add up to your list but it will take some time to gather them ALL.
And remember Cerrado jaguars average 87.5kg confirmed by IOP in a study probably prior to that of the comparison with the Cerrado Puma with not just 2 males because when they compare the cats sizes and habits on that study both cat's average sizes are already settled. So there was definitely a prior separated study on just their average sizes in depth otherwise they wouldn't make that ''an average sized cerrado jaguar of 87.5kg'' claim on their comparison study. And these studies about Cerrado jaguars were part of the requirements of obtaining PHD in animal biology in the university of Brasília so they should be taken completely serious.

Okay perfect! Once I have some free time I will sit down and do a compilation for both Northern and Southern Pantanal jaguars. This should be interesting :)

Add on your list Brazuca male 112kg and Nati male 110kg both southern pantanal males whom were collared by Onçafari project but both males didn't habituated for that long in the Caiman Ecological Refuge being monitored just out of the border probably because of the arrival of Xavier male which gave tough times to the males of the area. Xavier was no joke during his prime and its a shame he wasn't weighed.
Four more males to be added on your list are the misterious pantanal males we discussed in the jaguars of Brazil thread confirmed to be one of 130kg and the other 135kg. And also Mancha-Preta male 102kg and M&M male I saw he weights 121kg and he is monitored by Onças do Rio Negro.
About the average size due to the lack of enough infos and datas published for the public unfortunately. I still think the average Pantanal male is 105kg because for each small pantanal male of 100kg or slightly bellow, there are 3 larger ones. The Almeida's average was 90kg more than 40 years ago with jaguars on an enviornment and conditions I don't even wanna talk about, Peter Crawshaw himself knows what I am talking about cause he saw it all in person back then. They don't average 90kg anymore, NO WAY. People should bury that outdated claim nowadays once and for all.
Pantanal jaguars got the size they deserve TODAY.
you should also add Matheus 134kg and Sossego 130kg males. Onças do Rio Negro monitores both ( not Sossego anymore sadly ).
And from northern pantanal besides Juru and Adriano there's also that 148kg empty male. I think just the nowadays northern Pantanal males would be enough to TANK these outdated Almeida's weight datas, and if you add up the Southern Pantanal males it will be overkill
Too bad there are very few northern pantanal males verified, the much larger ones you'll find there.
There are more jaguars to be add up to your list but it will take some time to gather them ALL.
And remember Cerrado jaguars average 87.5kg confirmed by IOP in a study probably prior to that of the comparison with the Cerrado Puma with not just 2 males because when they compare the cats sizes and habits on that study both cat's average sizes are already settled. So there was definitely a prior separated study on just their average sizes in depth otherwise they wouldn't make that ''an average sized cerrado jaguar of 87.5kg'' claim on their comparison study. And these studies about Cerrado jaguars were part of the requirements of obtaining PHD in animal biology in the university of Brasília so they should be taken completely serious.
I wish I could get my hands on those files. :)
Okay perfect! Once I have some free time I will sit down and do a compilation for both Northern and Southern Pantanal jaguars. This should be interesting :)
Great and also big Cerrado males overlap with a few Pantanal males, large cerrado ones go from 105kg to 110kg with one confirmed to be 118kg as well as the misterious massive Tiago cerrado male who unfortunately nobody knows his size except Leandro and IOP.
