That problem reminded me about this video, it´s 10 years old but how much is changed really in that time....





That's interesting. Did they say his name and how old he was? Because old silverbacks are generally the largest silverbacks, and I don't think I've ever heard of an old established silverback ever being sedated for research or even medication, likely due to them normally having large groups around them at all times, though straying females or younger gorillas (including blackback males) seem fair game. Solitary silverbacks are the most likely to be sedated, they're normally the least established silverbacks of the park, with few exceptions.

And of course 199 kg is indeed a large animal in general especially compared to a normal human, but I don't think it represents anywhere near the largest of Eastern gorillas, which are normally old males. Old males are in the minority, due to how long they lived, so it's quite likely their weights have never been taken in the Virungas, Bwindi or Kahuzi Biega. They are proof of just how big an Eastern gorilla gets if it lives long enough. The most likely candidates of these measurements are males in their 20's or younger, due to how common they are and the more likely chances of them being solitary. Their late 20's is likely when they start getting really big, but that's if they live to their late 20's, let alone 48 years of age like the big Guhonda male.

So age is really important when talking about Eastern gorilla sizes. Western gorillas however seem to have a more constant size range regardless of age group and are generally smaller than Eastern gorillas.

I asked about biggest gorillas they know and I mentioned for instance Guhonda. And I asked if they have any weights and also if they have some educated guesses from professional people who are there working with these gorillas.

That first reply wasn´t surprising, because 199 kg gorilla for has to be huge, all available and reliable information after all give average weights clearly under 200 kg for males. Since estimations here have been lately much more than known biggest reliable weights, I thought that it´s good to ask from people who should know and maybe get something better than estimations from photos. Which is after all very unreliable way to make estimations, it´s like lottery. I´m sure, that if showing certain photos of for instance tigers, which weight under 200 kg and showing to people who don´t know which tiger, they would give estimations like 250-300 kg. Just because they can look from certain angles absolutely massive. 

Anyway I might get more information today, the person who replied said, that trying to find out more this morning from other people working there.
Sorry for another long comment, please be patient with me.
The thing is I'm not just using random pictures, nor am I making estimates out of thin air. My estimates were based on comparisons I made with the largest captive males on record, males that weighed 280 kg and 295 kg, so these weren't some random captive gorillas. I used to be like you, I used to doubt that gorillas could get very big and relied solely on scarce information on their size, but then I compared the biggest wild males to Samson a 295 kg captive Western gorilla, and I was shocked to see how similar those males were in body type to Samson. Though I do believe Samson was still a good amount heavier, he just wasn't significantly larger than them in bulk, and I made sure to use images of the gorillas in similar body positions so that the comparison works better. The other captive gorilla I used was M'bongo, he was actually a rare captive Eastern gorilla and he weighed over 280 kg at under 20 years of age. The image I used specifically was when he was a little bit smaller at 273 kg, and it amazed me just how close the biggest males especially Guhonda was to his body type, a lot closer than Samson. So again I made sure to use images of them in similar body positions, it wasn't like one was laying down and the other was sitting up or anything. I did two comparisons a few pages or so ago, so they're still here.

Like I said in my other comment, I understand that people make mistakes when estimating, including when using random pictures. That's why I chose to give them a size range instead of a definitive weight, because definitive weights are a lot harder to estimate and require an actual measurement. So seeing how similar their builds are to these 280 to 295 kg captive males, I was able to estimate their size range from 250 to 265 kg, probably even around 270 kg at the most. So these weights are for the absolute biggest Eastern gorillas, mainly the old males who are a minority compared to most of the males, who are still young and in their prime.

The weights given for Guhonda are most likely estimates without comparisons, so I tend to take such estimates with a grain of salt, whether it's high or low. I doubt they've ever weighed him and I doubt they would anytime soon, after all, dominant males especially dominant old males are the least likely to ever get sedated for research or medical reasons. Seeing how varied the estimations are for Guhonda, I seriously doubt you'll get anything conclusive from anyone. Now, I'm not saying my estimates are the absolute truth, but at least I had something to compare with, so that I could make sure my estimates were close to the truth rather than something from thin air.

There isn´t so much difference if estimation from photo is for instance 250 kg or 240-260 kg, it´s still unreliable way to estimate especially weight if there is nothing in the photo, which could be used in comparison so, that size of that other thing is known. With length or tallness it´s often a little bit easier, but still far from accurate.

For me things have been then quite opposite when looking what you tell. I mean, I used to estimate more (boldly) when younger and I was less skeptical. But with time I have become much more skeptic because so many mistakes by me and others. People tend to overestimate things they like. I asked now from people who should have much better overall understanding about gorillas than us, because I´m curious to know what kind of figures they give and with what kind of reasoning. They should know all these gorillas, like Guhonda and other famous ones and they know some weighed gorillas. So from these people we should be able to get some kind of understanding, because they actually have seen these gorillas in person and should know how massive for instance Guhonda is when compared to some others.

I haven´t got new message yet, but hopefully at some point today I will. It can take some time when asking from other people working there.
It's more reliable than just estimating them without a comparison. The problem is, you give them too much credit simply because they work there, what actually  makes you think they should know about each and every silverback gorilla's weight? Because dominant males are rarely if ever sedated, thus never weighed. I don't think seeing them in person is a better way to estimate than using images of actual measured specimens in comparisons, specimens who more likely than not have similar dimensions to these wild gorillas we're comparing them with. People like @GuateGojira have done great comparisons using photos, and give you a lot of perspective when you see them, which is the main goal of my comparisons, to give perspective and at least be able to put those gorillas in a specific weight range because of their similarities to those captive males.

The thing is, the people I would rather listen to are the people who actually weighed these specific gorillas, because at least they would be able to give a definitive weight for those specific males they measured. The problem is, the biggest males like Guhonda have pretty much never been weighed, and their estimates don't seem to do a lot of justice to them either, from 220 kg to 300 kg, nothing is definitive.

Like I said before, I never said my comparisons/ estimates were the absolute truth, but they're better than other baseless estimates from people who don't have anything to compare with and have never weighed the gorillas. To me, estimates are at their strongest if there's a comparison, or if someone knows the specifics which most of these people don't, after all, they've never weighed the gorillas in question. And I'm talking about big dominant males here, before you get confused, not solitary young males who are the most likely to be sedated and weighed.

Naturally I give a lot credit for people working with these animals if they tell something and give good reasoning. They can give much better estimations than people seeing gorillas only in photos and videos. Especially if/when they have seen some weighed individuals. There is room for error always even then, but for sure they have much more knowledge than us. I hope to get information from more than one person working there. Still people who have weighed gorillas give that normal range approximately 160-200 kg, not 220-300 kg.

With all due respect, that's kind of gullible. I understand they know a lot about the gorillas there, but just because they work there doesn't mean they know pretty much every single thing about gorilla weights, especially big dominant males who have never been weighed. 220 kg, 226 kg, 250 kg and 300 kg are the estimates I saw for males like Guhonda on the internet, I never said that was considered their average range. I want to do a little comparison, since you claimed weights around 190 kg are very large even for Eastern gorillas. I'll compare with a few big Eastern gorillas from three different populations.

Here's Shabani who is said to weigh 190 kg

Guhonda.

I could bring more but that would take too much space and it's kind of unnecessary, these images are enough to give perspective. I did this because you were adamant that similar weights like 199 or 200 kg were very large even for an Eastern gorilla, but it's quite obvious the apparent 190 kg Shabani or males similar to him are far from the sizes of the biggest Eastern gorillas, and that is clear as day. I know you're relying on what is considered their size range and what has been recorded, but don't these very large Eastern gorillas at least make you question whether those weights given are even conclusive or not? Because to me it shows again just how limited and scarce information on Eastern gorilla sizes are, this is something I've mentioned repeatedly.

Now, how you take this is up to you, you might try to deny it which is fine, but my aim is to really give perspective and show people what I'm talking about.

To me, estimates are at their strongest if there's a comparison, or if someone knows the specifics which most of these people don't, after all, they've never weighed the gorillas in question. And I'm talking about big dominant males here, before you get confused, not solitary young males who are the most likely to be sedated and weighed.

Naturally I give a lot credit for people working with these animals if they tell something and give good reasoning. They can give much better estimations than people seeing gorillas only in photos and videos. Especially if/when they have seen some weighed individuals. There is room for error always even then, but for sure they have much more knowledge than us. I hope to get information from more than one person working there. Still people who have weighed gorillas give that normal range approximately 160-200 kg, not 220-300 kg.
With all due respect, that's kind of gullible. I understand they know a lot about the gorillas there, but just because they work there doesn't mean they know pretty much every single thing about gorilla weights, especially big dominant males who have never been weighed. 220 kg, 226 kg, 250 kg and 300 kg are the estimates I saw for males like Guhonda on the internet, I never said that was considered their average range. I want to do a little comparison, since you claimed weights around 190 kg are very large even for Eastern gorillas. I'll compare with a few big Eastern gorillas from three different populations.

Here's Shabani who is said to weigh 190 kg

I could bring more but that would take too much space and it's kind of unnecessary, these images are enough to give perspective. I did this because you were adamant that similar weights like 199 or 200 kg were very large even for an Eastern gorilla, but it's quite obvious the apparent 190 kg Shabani or males similar to him are far from the sizes of the biggest Eastern gorillas, and that is clear as day. I know you're relying on what is considered their size range and what has been recorded, but don't these very large Eastern gorillas at least make you question whether those weights given are even conclusive or not? Because to me it shows again just how limited and scarce information on Eastern gorilla sizes are. 

Now, how you take this is up to you, you might try to deny it which is fine, but my aim is to really give perspective and show people what I'm talking about.

To keep this short since I´m busy now. I´ve seen Shabani and all those photos you shared countless times. So I have written all before fully aware how these gorillas look in photos. As I have said before, when you don´t have two animals side by side, it´s very difficult to make very big conclusions and be sure, that correct.

That´s why I have now sent some emails and trying to find out what those people, who have better possibilities to make estimations or maybe even know some weights, say. You make now comparisons in way, which I don´t consider as too reliable or accurate. You can be in some close, but also far away. Hopefully we get some good information and then know better how close you are or are you at all. I can´t say it now, but I am curious enough to try to find out.

Here is one quote:

"About all the questions you have asked, we do not have recent research done yet but what i have seen my self as a silver back gorilla, it was weighing 199 kgs, according to the research that was recently conducted by then on the same gorilla, it was indeed huge and its height am not sure, but it was not tall, what i know it was huge huge and huge. "


I might get some more information tomorrow at some time if lucky, but when I told about it, that participating to discussions about gorillas, I was asked to share this also here:


"Since you discuss a lot about life style of gorillas, add this issue on your table for further discussion https://www.virungaparkcongo.com/information/why-are-gorillas-poached/

You can actually share the link with your friends, people living nearby the park, have remained hostile to the gorillas, i really don't know what do to these people;"


That problem reminded me about this video, it´s 10 years old but how much is changed really in that time....





That's interesting. Did they say his name and how old he was? Because old silverbacks are generally the largest silverbacks, and I don't think I've ever heard of an old established silverback ever being sedated for research or even medication, likely due to them normally having large groups around them at all times, though straying females or younger gorillas (including blackback males) seem fair game. Solitary silverbacks are the most likely to be sedated, they're normally the least established silverbacks of the park, with few exceptions.

And of course 199 kg is indeed a large animal in general especially compared to a normal human, but I don't think it represents anywhere near the largest of Eastern gorillas, which are normally old males. Old males are in the minority, due to how long they lived, so it's quite likely their weights have never been taken in the Virungas, Bwindi or Kahuzi Biega. They are proof of just how big an Eastern gorilla gets if it lives long enough. The most likely candidates of these measurements are males in their 20's or younger, due to how common they are and the more likely chances of them being solitary. Their late 20's is likely when they start getting really big, but that's if they live to their late 20's, let alone 48 years of age like the big Guhonda male.

So age is really important when talking about Eastern gorilla sizes. Western gorillas however seem to have a more constant size range regardless of age group and are generally smaller than Eastern gorillas.

I asked about biggest gorillas they know and I mentioned for instance Guhonda. And I asked if they have any weights and also if they have some educated guesses from professional people who are there working with these gorillas.

That first reply wasn´t surprising, because 199 kg gorilla for has to be huge, all available and reliable information after all give average weights clearly under 200 kg for males. Since estimations here have been lately much more than known biggest reliable weights, I thought that it´s good to ask from people who should know and maybe get something better than estimations from photos. Which is after all very unreliable way to make estimations, it´s like lottery. I´m sure, that if showing certain photos of for instance tigers, which weight under 200 kg and showing to people who don´t know which tiger, they would give estimations like 250-300 kg. Just because they can look from certain angles absolutely massive. 

Anyway I might get more information today, the person who replied said, that trying to find out more this morning from other people working there.

Sorry for another long comment, please be patient with me.
The thing is I'm not just using random pictures, nor am I making estimates out of thin air. My estimates were based on comparisons I made with the largest captive males on record, males that weighed 280 kg and 295 kg, so these weren't some random captive gorillas. I used to be like you, I used to doubt that gorillas could get very big and relied solely on scarce information on their size, but then I compared the biggest wild males to Samson a 295 kg captive Western gorilla, and I was shocked to see how similar those males were in body type to Samson. Though I do believe Samson was still a good amount heavier, he just wasn't significantly larger than them in bulk, and I made sure to use images of the gorillas in similar body positions so that the comparison works better. The other captive gorilla I used was M'bongo, he was actually a rare captive Eastern gorilla and he weighed over 280 kg at under 20 years of age. The image I used specifically was when he was a little bit smaller at 273 kg, and it amazed me just how close the biggest males especially Guhonda was to his body type, a lot closer than Samson. So again I made sure to use images of them in similar body positions, it wasn't like one was laying down and the other was sitting up or anything. I did two comparisons a few pages or so ago, so they're still here.

Like I said in my other comment, I understand that people make mistakes when estimating, including when using random pictures. That's why I chose to give them a size range instead of a definitive weight, because definitive weights are a lot harder to estimate and require an actual measurement. So seeing how similar their builds are to these 280 to 295 kg captive males, I was able to estimate their size range from 250 to 265 kg, probably even around 270 kg at the most. So these weights are for the absolute biggest Eastern gorillas, mainly the old males who are a minority compared to most of the males, who are still young and in their prime.

The weights given for Guhonda are most likely estimates without comparisons, so I tend to take such estimates with a grain of salt, whether it's high or low. I doubt they've ever weighed him and I doubt they would anytime soon, after all, dominant males especially dominant old males are the least likely to ever get sedated for research or medical reasons. Seeing how varied the estimations are for Guhonda, I seriously doubt you'll get anything conclusive from anyone. Now, I'm not saying my estimates are the absolute truth, but at least I had something to compare with, so that I could make sure my estimates were close to the truth rather than something from thin air.
[/quote]

There isn´t so much difference if estimation from photo is for instance 250 kg or 240-260 kg, it´s still unreliable way to estimate especially weight if there is nothing in the photo, which could be used in comparison so, that size of that other thing is known. With length or tallness it´s often a little bit easier, but still far from accurate.

For me things have been then quite opposite when looking what you tell. I mean, I used to estimate more (boldly) when younger and I was less skeptical. But with time I have become much more skeptic because so many mistakes by me and others. People tend to overestimate things they like. I asked now from people who should have much better overall understanding about gorillas than us, because I´m curious to know what kind of figures they give and with what kind of reasoning. They should know all these gorillas, like Guhonda and other famous ones and they know some weighed gorillas. So from these people we should be able to get some kind of understanding, because they actually have seen these gorillas in person and should know how massive for instance Guhonda is when compared to some others.

I haven´t got new message yet, but hopefully at some point today I will. It can take some time when asking from other people working there.

It's more reliable than just estimating them without a comparison. The problem is, you give them too much credit simply because they work there, what actually  makes you think they should know about each and every silverback gorilla's weight? Because dominant males are rarely if ever sedated, thus never weighed. I don't think seeing them in person is a better way to estimate than using images of actual measured specimens in comparisons, specimens who more likely than not have similar dimensions to these wild gorillas we're comparing them with. People like @GuateGojira have done great comparisons using photos, and give you a lot of perspective when you see them, which is the main goal of my comparisons, to give perspective and at least be able to put those gorillas in a specific weight range because of their similarities to those captive males.

The thing is, the people I would rather listen to are the people who actually weighed these specific gorillas, because at least they would be able to give a definitive weight for those specific males they measured. The problem is, the biggest males like Guhonda have pretty much never been weighed, and their estimates don't seem to do a lot of justice to them either, from 220 kg to 300 kg, nothing is definitive.

I understand that, but it's quite obvious they're much heavier than the 190 kg Shabani. Unless you think these Eastern gorillas are dwarfs (which I doubt you do), then there is no possible and logical way for Shabani to be anywhere near their weight. To me it's kind of denying the obvious to act like they're not much heavier than him, when it's quite clear. So again, unless you think those gorillas are dwarfs, then there's really no reason to doubt they're much heavier than Shabani.

Like I mentioned about sedating and weighing big dominant males being unlikely, here's an example.
https://www.gorilladoctors.org/three-hea...two-weeks/
"As Cantsbee is the dominant silverback, we did not want to seriously disrupt the group by sedating their leader if it was not absolutely necessary." 
Skip to the bottom to see the Cantsbee highlighted in green. This shows an example of why it's very unlikely that they'll sedate a big dominant male just to weigh him, or even for regular health checks

The most likely chance of big dominant males being weighed is after death. Like Senkwekwe who was unfortunately killed along with group members in 2007. I remember reading something that said he weighed 250 kg, which is possible because this was after death, so that means there was a good chance to potentially weigh his corpse.
https://books.google.co.uk/books?id=4WTK...kg&f=false

He did indeed look like the very big silverbacks that are alive today.

Looks like, that you quote me in some way and have links and photos. For some reason your message opens up messy and is difficult to read. Anyway that link you share and that photo are nothing new for me, I´ve seen those before and I´m also very well aware about it, that they don´t sedate gorillas often. That´s why I contacted Virunga park people and asking from them directly in hope to find out more than it´s possible to find from internet. Patience is needed as usually, but I hope that soon I can share what they tell.

Hopefully we get some good information and then know better how close you are or are you at all. I can´t say it now, but I am curious enough to try to find out.
I understand that, but it's quite obvious they're much heavier than the 190 kg Shabani. Unless you think these Eastern gorillas are dwarfs (which I doubt you do), then there is no possible and logical way for Shabani to be anywhere near their weight. To me it's kind of denying the obvious to act like they're not much heavier than him, when it's quite clear. So again, unless you think those gorillas are dwarfs, then there's really no reason to doubt they're much heavier than Shabani.

Like I mentioned about sedating and weighing big dominant males being unlikely, here's an example.
https://www.gorilladoctors.org/three-hea...two-weeks/
"As Cantsbee is the dominant silverback, we did not want to seriously disrupt the group by sedating their leader if it was not absolutely necessary." 
Skip to the bottom to see the Cantsbee highlighted in green. This shows an example of why it's very unlikely that they'll sedate a big dominant male just to weigh him, or even for regular health checks

The most likely chance of big dominant males being weighed is after death. Like Senkwekwe who was unfortunately killed along with group members in 2007. I remember reading something that said he weighed 250 kg, which is possible because this was after death, so that means there was a good chance to potentially weigh his corpse.

He did indeed look like the very big silverbacks that are alive today.

Here is one quote:

"About all the questions you have asked, we do not have recent research done yet but what i have seen my self as a silver back gorilla, it was weighing 199 kgs, according to the research that was recently conducted by then on the same gorilla, it was indeed huge and its height am not sure, but it was not tall, what i know it was huge huge and huge. "


I might get some more information tomorrow at some time if lucky, but when I told about it, that participating to discussions about gorillas, I was asked to share this also here:


"Since you discuss a lot about life style of gorillas, add this issue on your table for further discussion https://www.virungaparkcongo.com/information/why-are-gorillas-poached/

You can actually share the link with your friends, people living nearby the park, have remained hostile to the gorillas, i really don't know what do to these people;"


That problem reminded me about this video, it´s 10 years old but how much is changed really in that time....





That's interesting. Did they say his name and how old he was? Because old silverbacks are generally the largest silverbacks, and I don't think I've ever heard of an old established silverback ever being sedated for research or even medication, likely due to them normally having large groups around them at all times, though straying females or younger gorillas (including blackback males) seem fair game. Solitary silverbacks are the most likely to be sedated, they're normally the least established silverbacks of the park, with few exceptions.

And of course 199 kg is indeed a large animal in general especially compared to a normal human, but I don't think it represents anywhere near the largest of Eastern gorillas, which are normally old males. Old males are in the minority, due to how long they lived, so it's quite likely their weights have never been taken in the Virungas, Bwindi or Kahuzi Biega. They are proof of just how big an Eastern gorilla gets if it lives long enough. The most likely candidates of these measurements are males in their 20's or younger, due to how common they are and the more likely chances of them being solitary. Their late 20's is likely when they start getting really big, but that's if they live to their late 20's, let alone 48 years of age like the big Guhonda male.

So age is really important when talking about Eastern gorilla sizes. Western gorillas however seem to have a more constant size range regardless of age group and are generally smaller than Eastern gorillas.

I asked about biggest gorillas they know and I mentioned for instance Guhonda. And I asked if they have any weights and also if they have some educated guesses from professional people who are there working with these gorillas.

That first reply wasn´t surprising, because 199 kg gorilla for has to be huge, all available and reliable information after all give average weights clearly under 200 kg for males. Since estimations here have been lately much more than known biggest reliable weights, I thought that it´s good to ask from people who should know and maybe get something better than estimations from photos. Which is after all very unreliable way to make estimations, it´s like lottery. I´m sure, that if showing certain photos of for instance tigers, which weight under 200 kg and showing to people who don´t know which tiger, they would give estimations like 250-300 kg. Just because they can look from certain angles absolutely massive. 

Anyway I might get more information today, the person who replied said, that trying to find out more this morning from other people working there.
Sorry for another long comment, please be patient with me.
The thing is I'm not just using random pictures, nor am I making estimates out of thin air. My estimates were based on comparisons I made with the largest captive males on record, males that weighed 280 kg and 295 kg, so these weren't some random captive gorillas. I used to be like you, I used to doubt that gorillas could get very big and relied solely on scarce information on their size, but then I compared the biggest wild males to Samson a 295 kg captive Western gorilla, and I was shocked to see how similar those males were in body type to Samson. Though I do believe Samson was still a good amount heavier, he just wasn't significantly larger than them in bulk, and I made sure to use images of the gorillas in similar body positions so that the comparison works better. The other captive gorilla I used was M'bongo, he was actually a rare captive Eastern gorilla and he weighed over 280 kg at under 20 years of age. The image I used specifically was when he was a little bit smaller at 273 kg, and it amazed me just how close the biggest males especially Guhonda was to his body type, a lot closer than Samson. So again I made sure to use images of them in similar body positions, it wasn't like one was laying down and the other was sitting up or anything. I did two comparisons a few pages or so ago, so they're still here.

Like I said in my other comment, I understand that people make mistakes when estimating, including when using random pictures. That's why I chose to give them a size range instead of a definitive weight, because definitive weights are a lot harder to estimate and require an actual measurement. So seeing how similar their builds are to these 280 to 295 kg captive males, I was able to estimate their size range from 250 to 265 kg, probably even around 270 kg at the most. So these weights are for the absolute biggest Eastern gorillas, mainly the old males who are a minority compared to most of the males, who are still young and in their prime.

The weights given for Guhonda are most likely estimates without comparisons, so I tend to take such estimates with a grain of salt, whether it's high or low. I doubt they've ever weighed him and I doubt they would anytime soon, after all, dominant males especially dominant old males are the least likely to ever get sedated for research or medical reasons. Seeing how varied the estimations are for Guhonda, I seriously doubt you'll get anything conclusive from anyone. Now, I'm not saying my estimates are the absolute truth, but at least I had something to compare with, so that I could make sure my estimates were close to the truth rather than something from thin air.

There isn´t so much difference if estimation from photo is for instance 250 kg or 240-260 kg, it´s still unreliable way to estimate especially weight if there is nothing in the photo, which could be used in comparison so, that size of that other thing is known. With length or tallness it´s often a little bit easier, but still far from accurate.

For me things have been then quite opposite when looking what you tell. I mean, I used to estimate more (boldly) when younger and I was less skeptical. But with time I have become much more skeptic because so many mistakes by me and others. People tend to overestimate things they like. I asked now from people who should have much better overall understanding about gorillas than us, because I´m curious to know what kind of figures they give and with what kind of reasoning. They should know all these gorillas, like Guhonda and other famous ones and they know some weighed gorillas. So from these people we should be able to get some kind of understanding, because they actually have seen these gorillas in person and should know how massive for instance Guhonda is when compared to some others.

I haven´t got new message yet, but hopefully at some point today I will. It can take some time when asking from other people working there.
It's more reliable than just estimating them without a comparison. The problem is, you give them too much credit simply because they work there, what actually  makes you think they should know about each and every silverback gorilla's weight? Because dominant males are rarely if ever sedated, thus never weighed. I don't think seeing them in person is a better way to estimate than using images of actual measured specimens in comparisons, specimens who more likely than not have similar dimensions to these wild gorillas we're comparing them with. People like @GuateGojira have done great comparisons using photos, and give you a lot of perspective when you see them, which is the main goal of my comparisons, to give perspective and at least be able to put those gorillas in a specific weight range because of their similarities to those captive males.

The thing is, the people I would rather listen to are the people who actually weighed these specific gorillas, because at least they would be able to give a definitive weight for those specific males they measured. The problem is, the biggest males like Guhonda have pretty much never been weighed, and their estimates don't seem to do a lot of justice to them either, from 220 kg to 300 kg, nothing is definitive.

Like I said before, I never said my comparisons/ estimates were the absolute truth, but they're better than other baseless estimates from people who don't have anything to compare with and have never weighed the gorillas. To me, estimates are at their strongest if there's a comparison, or if someone knows the specifics which most of these people don't, after all, they've never weighed the gorillas in question. And I'm talking about big dominant males here, before you get confused, not solitary young males who are the most likely to be sedated and weighed.

Naturally I give a lot credit for people working with these animals if they tell something and give good reasoning. They can give much better estimations than people seeing gorillas only in photos and videos. Especially if/when they have seen some weighed individuals. There is room for error always even then, but for sure they have much more knowledge than us. I hope to get information from more than one person working there. Still people who have weighed gorillas give that normal range approximately 160-200 kg, not 220-300 kg.
With all due respect, that's kind of gullible. I understand they know a lot about the gorillas there, but just because they work there doesn't mean they know pretty much every single thing about gorilla weights, especially big dominant males who have never been weighed. 220 kg, 226 kg, 250 kg and 300 kg are the estimates I saw for males like Guhonda on the internet, I never said that was considered their average range. I want to do a little comparison, since you claimed weights around 190 kg are very large even for Eastern gorillas. I'll compare with a few big Eastern gorillas from three different populations.

Here's Shabani who is said to weigh 190 kg

I could bring more but that would take too much space and it's kind of unnecessary, these images are enough to give perspective. I did this because you were adamant that similar weights like 199 or 200 kg were very large even for an Eastern gorilla, but it's quite obvious the apparent 190 kg Shabani or males similar to him are far from the sizes of the biggest Eastern gorillas, and that is clear as day. I know you're relying on what is considered their size range and what has been recorded, but don't these very large Eastern gorillas at least make you question whether those weights given are even conclusive or not? Because to me it shows again just how limited and scarce information on Eastern gorilla sizes are. 

Now, how you take this is up to you, you might try to deny it which is fine, but my aim is to really give perspective and show people what I'm talking about.

To keep this short since I´m busy now. I´ve seen Shabani and all those photos you shared countless times. So I have written all before fully aware how these gorillas look in photos. As I have said before, when you don´t have two animals side by side, it´s very difficult to make very big conclusions and be sure, that correct.

That´s why I have now sent some emails and trying to find out what those people, who have better possibilities to make estimations or maybe even know some weights, say. You make now comparisons in way, which I don´t consider as too reliable or accurate. You can be in some close, but also far away. Hopefully we get some good information and then know better how close you are or are you at all. I can´t say it now, but I am curious enough to try to find out.
I understand that, but it's quite obvious they're much heavier than the 190 kg Shabani. Unless you think these Eastern gorillas are dwarfs (which I doubt you do), then there is no possible and logical way for Shabani to be anywhere near their weight. To me it's kind of denying the obvious to act like they're not much heavier than him, when it's quite clear.

I know how you think, you have said it many times. I have also seen all these photos and information you shared before. Nothing new. That´s why I am now contacting people who work with these gorillas to get information and opinions from them, who actually live and work there with these gorillas, because it´s difficult to find anything new from internet anymore.

One remark what comes to poor Senkwekwe. In photos after death he looks like started to fill with gasses, which from when decomposition starts. On that photo in which he is lifted on car, his body looks swollen, I wouldn´t touch that kind of carcass with a sharp object. There is at least one video, in which a lion bites a zebra carcass in similar state and it was like a "shitplosion". I actually asked about Senkwekwe too, because I´ve been curious to know how his weight was estimated or was it really weighed. I´ve never seen information saying, that he would have been weighed, so it looks like to be estimation by someone. Hopefully we can know it one day.

Because old silverbacks are generally the largest silverbacks, and I don't think I've ever heard of an old established silverback ever being sedated for research or even medication, likely due to them normally having large groups around them at all times, though straying females or younger gorillas (including blackback males) seem fair game. Solitary silverbacks are the most likely to be sedated, they're normally the least established silverbacks of the park, with few exceptions.

And of course 199 kg is indeed a large animal in general especially compared to a normal human, but I don't think it represents anywhere near the largest of Eastern gorillas, which are normally old males. Old males are in the minority, due to how long they lived, so it's quite likely their weights have never been taken in the Virungas, Bwindi or Kahuzi Biega. They are proof of just how big an Eastern gorilla gets if it lives long enough. The most likely candidates of these measurements are males in their 20's or younger, due to how common they are and the more likely chances of them being solitary. Their late 20's is likely when they start getting really big, but that's if they live to their late 20's, let alone 48 years of age like the big Guhonda male.

So age is really important when talking about Eastern gorilla sizes. Western gorillas however seem to have a more constant size range regardless of age group and are generally smaller than Eastern gorillas.

I asked about biggest gorillas they know and I mentioned for instance Guhonda. And I asked if they have any weights and also if they have some educated guesses from professional people who are there working with these gorillas.

That first reply wasn´t surprising, because 199 kg gorilla for has to be huge, all available and reliable information after all give average weights clearly under 200 kg for males. Since estimations here have been lately much more than known biggest reliable weights, I thought that it´s good to ask from people who should know and maybe get something better than estimations from photos. Which is after all very unreliable way to make estimations, it´s like lottery. I´m sure, that if showing certain photos of for instance tigers, which weight under 200 kg and showing to people who don´t know which tiger, they would give estimations like 250-300 kg. Just because they can look from certain angles absolutely massive. 

Anyway I might get more information today, the person who replied said, that trying to find out more this morning from other people working there.
Sorry for another long comment, please be patient with me.
The thing is I'm not just using random pictures, nor am I making estimates out of thin air. My estimates were based on comparisons I made with the largest captive males on record, males that weighed 280 kg and 295 kg, so these weren't some random captive gorillas. I used to be like you, I used to doubt that gorillas could get very big and relied solely on scarce information on their size, but then I compared the biggest wild males to Samson a 295 kg captive Western gorilla, and I was shocked to see how similar those males were in body type to Samson. Though I do believe Samson was still a good amount heavier, he just wasn't significantly larger than them in bulk, and I made sure to use images of the gorillas in similar body positions so that the comparison works better. The other captive gorilla I used was M'bongo, he was actually a rare captive Eastern gorilla and he weighed over 280 kg at under 20 years of age. The image I used specifically was when he was a little bit smaller at 273 kg, and it amazed me just how close the biggest males especially Guhonda was to his body type, a lot closer than Samson. So again I made sure to use images of them in similar body positions, it wasn't like one was laying down and the other was sitting up or anything. I did two comparisons a few pages or so ago, so they're still here.

Like I said in my other comment, I understand that people make mistakes when estimating, including when using random pictures. That's why I chose to give them a size range instead of a definitive weight, because definitive weights are a lot harder to estimate and require an actual measurement. So seeing how similar their builds are to these 280 to 295 kg captive males, I was able to estimate their size range from 250 to 265 kg, probably even around 270 kg at the most. So these weights are for the absolute biggest Eastern gorillas, mainly the old males who are a minority compared to most of the males, who are still young and in their prime.

The weights given for Guhonda are most likely estimates without comparisons, so I tend to take such estimates with a grain of salt, whether it's high or low. I doubt they've ever weighed him and I doubt they would anytime soon, after all, dominant males especially dominant old males are the least likely to ever get sedated for research or medical reasons. Seeing how varied the estimations are for Guhonda, I seriously doubt you'll get anything conclusive from anyone. Now, I'm not saying my estimates are the absolute truth, but at least I had something to compare with, so that I could make sure my estimates were close to the truth rather than something from thin air.

There isn´t so much difference if estimation from photo is for instance 250 kg or 240-260 kg, it´s still unreliable way to estimate especially weight if there is nothing in the photo, which could be used in comparison so, that size of that other thing is known. With length or tallness it´s often a little bit easier, but still far from accurate.

For me things have been then quite opposite when looking what you tell. I mean, I used to estimate more (boldly) when younger and I was less skeptical. But with time I have become much more skeptic because so many mistakes by me and others. People tend to overestimate things they like. I asked now from people who should have much better overall understanding about gorillas than us, because I´m curious to know what kind of figures they give and with what kind of reasoning. They should know all these gorillas, like Guhonda and other famous ones and they know some weighed gorillas. So from these people we should be able to get some kind of understanding, because they actually have seen these gorillas in person and should know how massive for instance Guhonda is when compared to some others.

I haven´t got new message yet, but hopefully at some point today I will. It can take some time when asking from other people working there.
It's more reliable than just estimating them without a comparison. The problem is, you give them too much credit simply because they work there, what actually  makes you think they should know about each and every silverback gorilla's weight? Because dominant males are rarely if ever sedated, thus never weighed. I don't think seeing them in person is a better way to estimate than using images of actual measured specimens in comparisons, specimens who more likely than not have similar dimensions to these wild gorillas we're comparing them with. People like @GuateGojira have done great comparisons using photos, and give you a lot of perspective when you see them, which is the main goal of my comparisons, to give perspective and at least be able to put those gorillas in a specific weight range because of their similarities to those captive males.

The thing is, the people I would rather listen to are the people who actually weighed these specific gorillas, because at least they would be able to give a definitive weight for those specific males they measured. The problem is, the biggest males like Guhonda have pretty much never been weighed, and their estimates don't seem to do a lot of justice to them either, from 220 kg to 300 kg, nothing is definitive.

Like I said before, I never said my comparisons/ estimates were the absolute truth, but they're better than other baseless estimates from people who don't have anything to compare with and have never weighed the gorillas. To me, estimates are at their strongest if there's a comparison, or if someone knows the specifics which most of these people don't, after all, they've never weighed the gorillas in question. And I'm talking about big dominant males here, before you get confused, not solitary young males who are the most likely to be sedated and weighed.

Naturally I give a lot credit for people working with these animals if they tell something and give good reasoning. They can give much better estimations than people seeing gorillas only in photos and videos. Especially if/when they have seen some weighed individuals. There is room for error always even then, but for sure they have much more knowledge than us. I hope to get information from more than one person working there. Still people who have weighed gorillas give that normal range approximately 160-200 kg, not 220-300 kg.
With all due respect, that's kind of gullible. I understand they know a lot about the gorillas there, but just because they work there doesn't mean they know pretty much every single thing about gorilla weights, especially big dominant males who have never been weighed. 220 kg, 226 kg, 250 kg and 300 kg are the estimates I saw for males like Guhonda on the internet, I never said that was considered their average range. I want to do a little comparison, since you claimed weights around 190 kg are very large even for Eastern gorillas. I'll compare with a few big Eastern gorillas from three different populations.

Here's Shabani who is said to weigh 190 kg

I could bring more but that would take too much space and it's kind of unnecessary, these images are enough to give perspective. I did this because you were adamant that similar weights like 199 or 200 kg were very large even for an Eastern gorilla, but it's quite obvious the apparent 190 kg Shabani or males similar to him are far from the sizes of the biggest Eastern gorillas, and that is clear as day. I know you're relying on what is considered their size range and what has been recorded, but don't these very large Eastern gorillas at least make you question whether those weights given are even conclusive or not? Because to me it shows again just how limited and scarce information on Eastern gorilla sizes are. 

Now, how you take this is up to you, you might try to deny it which is fine, but my aim is to really give perspective and show people what I'm talking about.

To keep this short since I´m busy now. I´ve seen Shabani and all those photos you shared countless times. So I have written all before fully aware how these gorillas look in photos. As I have said before, when you don´t have two animals side by side, it´s very difficult to make very big conclusions and be sure, that correct.

That´s why I have now sent some emails and trying to find out what those people, who have better possibilities to make estimations or maybe even know some weights, say. You make now comparisons in way, which I don´t consider as too reliable or accurate. You can be in some close, but also far away. Hopefully we get some good information and then know better how close you are or are you at all. I can´t say it now, but I am curious enough to try to find out.
I understand that, but it's quite obvious they're much heavier than the 190 kg Shabani. Unless you think these Eastern gorillas are dwarfs (which I doubt you do), then there is no possible and logical way for Shabani to be anywhere near their weight. To me it's kind of denying the obvious to act like they're not much heavier than him, when it's quite clear. So again, unless you think those gorillas are dwarfs, then there's really no reason to doubt they're much heavier than Shabani.

Like I mentioned about sedating and weighing big dominant males being unlikely, here's an example.
https://www.gorilladoctors.org/three-hea...two-weeks/
"As Cantsbee is the dominant silverback, we did not want to seriously disrupt the group by sedating their leader if it was not absolutely necessary." 
Skip to the bottom to see the Cantsbee highlighted in green. This shows an example of why it's very unlikely that they'll sedate a big dominant male just to weigh him, or even for regular health checks

The most likely chance of big dominant males being weighed is after death. Like Senkwekwe who was unfortunately killed along with group members in 2007. I remember reading something that said he weighed 250 kg, which is possible because this was after death, so that means there was a good chance to potentially weigh his corpse.
https://books.google.co.uk/books?id=4WTK...kg&f=false

He did indeed look like the very big silverbacks that are alive today.

*This image is copyright of its original author

One remark what comes to poor Senkwekwe. In photos after death he looks like started to fill with gasses, which from when decomposition starts. On that photo in which he is lifted on car, his body looks swollen, I wouldn´t touch that kind of carcass with a sharp object. There is at least one video, in which a lion bites a zebra carcass in similar state and it was like a "shitplosion". I actually asked about Senkwekwe too, because I´ve been curious to know how his weight was estimated or was it really weighed. I´ve never seen information saying, that he would have been weighed, so it looks like to be estimation by someone. Hopefully we can know it one day.
I also never claimed he was actually weighed, I just mentioned there was more potential for that due to him being dead, which was something much less likely to happen if he was alive. So it was more believable for that reason.

His body doesn't look too bad compared to living big males, he was not that far into decomposition. Here's what Guhonda looks like laying down.

*This image is copyright of its original author

So Senkwekwe's body doesn't look too different from living big males, but I understand what you're saying. I agree, hopefully one day there will be full answers, and I hope we're not old and grey when that happens.

For me Senkwekwe looks like to be bloated by gasses, in that photo where he is on the car it´s looks more more obvious to my eyes. He wasn´t found right after shooting so it´s a bit difficult to know. I remembered one old article about him and managed to find it. There are some more details. Also in that is told, that they had some burial place for gorillas and they were carrying gorillas there, so it looks like, that he wasn´t weighed. After all they knew how he died and if decomposition had started, they most probably buried gorillas asap.

I hope, that sometime during next week something from Virunga park. Here that article telling what happened, when Senkwekwe and many other gorillas were killed:

The image I used specifically was when he was a little bit smaller at 273 kg, and it amazed me just how close the biggest males especially Guhonda was to his body type, a lot closer than Samson. So again I made sure to use images of them in similar body positions, it wasn't like one was laying down and the other was sitting up or anything. I did two comparisons a few pages or so ago, so they're still here.

Like I said in my other comment, I understand that people make mistakes when estimating, including when using random pictures. That's why I chose to give them a size range instead of a definitive weight, because definitive weights are a lot harder to estimate and require an actual measurement. So seeing how similar their builds are to these 280 to 295 kg captive males, I was able to estimate their size range from 250 to 265 kg, probably even around 270 kg at the most. So these weights are for the absolute biggest Eastern gorillas, mainly the old males who are a minority compared to most of the males, who are still young and in their prime.

The weights given for Guhonda are most likely estimates without comparisons, so I tend to take such estimates with a grain of salt, whether it's high or low. I doubt they've ever weighed him and I doubt they would anytime soon, after all, dominant males especially dominant old males are the least likely to ever get sedated for research or medical reasons. Seeing how varied the estimations are for Guhonda, I seriously doubt you'll get anything conclusive from anyone. Now, I'm not saying my estimates are the absolute truth, but at least I had something to compare with, so that I could make sure my estimates were close to the truth rather than something from thin air.

There isn´t so much difference if estimation from photo is for instance 250 kg or 240-260 kg, it´s still unreliable way to estimate especially weight if there is nothing in the photo, which could be used in comparison so, that size of that other thing is known. With length or tallness it´s often a little bit easier, but still far from accurate.

For me things have been then quite opposite when looking what you tell. I mean, I used to estimate more (boldly) when younger and I was less skeptical. But with time I have become much more skeptic because so many mistakes by me and others. People tend to overestimate things they like. I asked now from people who should have much better overall understanding about gorillas than us, because I´m curious to know what kind of figures they give and with what kind of reasoning. They should know all these gorillas, like Guhonda and other famous ones and they know some weighed gorillas. So from these people we should be able to get some kind of understanding, because they actually have seen these gorillas in person and should know how massive for instance Guhonda is when compared to some others.

I haven´t got new message yet, but hopefully at some point today I will. It can take some time when asking from other people working there.
It's more reliable than just estimating them without a comparison. The problem is, you give them too much credit simply because they work there, what actually  makes you think they should know about each and every silverback gorilla's weight? Because dominant males are rarely if ever sedated, thus never weighed. I don't think seeing them in person is a better way to estimate than using images of actual measured specimens in comparisons, specimens who more likely than not have similar dimensions to these wild gorillas we're comparing them with. People like @GuateGojira have done great comparisons using photos, and give you a lot of perspective when you see them, which is the main goal of my comparisons, to give perspective and at least be able to put those gorillas in a specific weight range because of their similarities to those captive males.

The thing is, the people I would rather listen to are the people who actually weighed these specific gorillas, because at least they would be able to give a definitive weight for those specific males they measured. The problem is, the biggest males like Guhonda have pretty much never been weighed, and their estimates don't seem to do a lot of justice to them either, from 220 kg to 300 kg, nothing is definitive.

Like I said before, I never said my comparisons/ estimates were the absolute truth, but they're better than other baseless estimates from people who don't have anything to compare with and have never weighed the gorillas. To me, estimates are at their strongest if there's a comparison, or if someone knows the specifics which most of these people don't, after all, they've never weighed the gorillas in question. And I'm talking about big dominant males here, before you get confused, not solitary young males who are the most likely to be sedated and weighed.

Naturally I give a lot credit for people working with these animals if they tell something and give good reasoning. They can give much better estimations than people seeing gorillas only in photos and videos. Especially if/when they have seen some weighed individuals. There is room for error always even then, but for sure they have much more knowledge than us. I hope to get information from more than one person working there. Still people who have weighed gorillas give that normal range approximately 160-200 kg, not 220-300 kg.
With all due respect, that's kind of gullible. I understand they know a lot about the gorillas there, but just because they work there doesn't mean they know pretty much every single thing about gorilla weights, especially big dominant males who have never been weighed. 220 kg, 226 kg, 250 kg and 300 kg are the estimates I saw for males like Guhonda on the internet, I never said that was considered their average range. I want to do a little comparison, since you claimed weights around 190 kg are very large even for Eastern gorillas. I'll compare with a few big Eastern gorillas from three different populations.

Here's Shabani who is said to weigh 190 kg

I could bring more but that would take too much space and it's kind of unnecessary, these images are enough to give perspective. I did this because you were adamant that similar weights like 199 or 200 kg were very large even for an Eastern gorilla, but it's quite obvious the apparent 190 kg Shabani or males similar to him are far from the sizes of the biggest Eastern gorillas, and that is clear as day. I know you're relying on what is considered their size range and what has been recorded, but don't these very large Eastern gorillas at least make you question whether those weights given are even conclusive or not? Because to me it shows again just how limited and scarce information on Eastern gorilla sizes are. 

Now, how you take this is up to you, you might try to deny it which is fine, but my aim is to really give perspective and show people what I'm talking about.

To keep this short since I´m busy now. I´ve seen Shabani and all those photos you shared countless times. So I have written all before fully aware how these gorillas look in photos. As I have said before, when you don´t have two animals side by side, it´s very difficult to make very big conclusions and be sure, that correct.

That´s why I have now sent some emails and trying to find out what those people, who have better possibilities to make estimations or maybe even know some weights, say. You make now comparisons in way, which I don´t consider as too reliable or accurate. You can be in some close, but also far away. Hopefully we get some good information and then know better how close you are or are you at all. I can´t say it now, but I am curious enough to try to find out.
I understand that, but it's quite obvious they're much heavier than the 190 kg Shabani. Unless you think these Eastern gorillas are dwarfs (which I doubt you do), then there is no possible and logical way for Shabani to be anywhere near their weight. To me it's kind of denying the obvious to act like they're not much heavier than him, when it's quite clear. So again, unless you think those gorillas are dwarfs, then there's really no reason to doubt they're much heavier than Shabani.

Like I mentioned about sedating and weighing big dominant males being unlikely, here's an example.
https://www.gorilladoctors.org/three-hea...two-weeks/
"As Cantsbee is the dominant silverback, we did not want to seriously disrupt the group by sedating their leader if it was not absolutely necessary." 
Skip to the bottom to see the Cantsbee highlighted in green. This shows an example of why it's very unlikely that they'll sedate a big dominant male just to weigh him, or even for regular health checks

The most likely chance of big dominant males being weighed is after death. Like Senkwekwe who was unfortunately killed along with group members in 2007. I remember reading something that said he weighed 250 kg, which is possible because this was after death, so that means there was a good chance to potentially weigh his corpse.
https://books.google.co.uk/books?id=4WTK...kg&f=false

He did indeed look like the very big silverbacks that are alive today.

*This image is copyright of its original author

One remark what comes to poor Senkwekwe. In photos after death he looks like started to fill with gasses, which from when decomposition starts. On that photo in which he is lifted on car, his body looks swollen, I wouldn´t touch that kind of carcass with a sharp object. There is at least one video, in which a lion bites a zebra carcass in similar state and it was like a "shitplosion". I actually asked about Senkwekwe too, because I´ve been curious to know how his weight was estimated or was it really weighed. I´ve never seen information saying, that he would have been weighed, so it looks like to be estimation by someone. Hopefully we can know it one day.
I also never claimed he was actually weighed, I just mentioned there was more potential for that due to him being dead, which was something much less likely to happen if he was alive. So it was more believable for that reason.

His body doesn't look too bad compared to living big males, he was not that far into decomposition. Here's what Guhonda looks like laying down.


*This image is copyright of its original author


*This image is copyright of its original author

So Senkwekwe's body doesn't look too different from living big males, but I understand what you're saying. I agree, hopefully one day there will be full answers, and I hope we're not old and grey when that happens.
For me Senkwekwe looks like to be bloated by gasses, in that photo where he is on the car it´s looks more more obvious to my eyes. He wasn´t found right after shooting so it´s a bit difficult to know. I remembered one old article about him and managed to find it. There are some more details. Also in that is told, that they had some burial place for gorillas and they were carrying gorillas there, so it looks like, that he wasn´t weighed. After all they knew how he died and if decomposition had started, they most probably buried gorillas asap.

I hope, that sometime during next week something from Virunga park. Here that article telling what happened, when Senkwekwe and many other gorillas were killed:
https://www.theguardian.com/artanddesign/2015/oct/22/brent-stirton-best-photograph-dead-silverback-gorilla-congo-virunga
That's fine, even though to me he doesn't look too different from living males, which is my point, but OK. Yes, I know about the burial and even seen the grave site back in 2011 which was very nice of them, but I already explained why them weighing him was more believable than them weighing living big males. So my point was to highlight the possibility, hence why I used words like "potential" in that comment instead of acting like they definitively weighed him, which I understand was unlikely but not impossible. Anyway, we've had a pretty good conversation on this, which is great, hopefully full confirmed information comes out about this subject eventually but I won't hold my breath for it. I still strongly believe that the biggest Eastern gorillas are significantly bigger than the 190 kg Shabani or males similar to that, it's just that obvious, unless you think they're dwarfs, which is impossible. So until next time whenever that is, good day to you.

So until next time whenever that is, good day to you.

One of the main things in these conversations, imo, is to notice and understand, that different people can look at same photos and videos and see things differently. And that it´s nothing personal. In past and of course nowadays too that is one major problem and challenge to overcome. 

For instance when looking at Shabani and some wild gorillas, I can´t say if wild gorillas are really bigger in some way, what comes to robustness and overall size, when we count out older males with big bellies. Shabani was and is a big gorilla, 180 cm tall, for sure there are some as tall and taller gorillas, but when looking at average gorilla, Shabani is a big one. Nowadays he is told to be 190 kg, earlier 170 kg, I don´t know when those photos which you shared have been taken, actually it would be interesting to see photos of him, when he was 12-15 years old and then some recent ones and see how much difference, it looks like they pay attention to food in that zoo where he is and don´t let him become obese easily.

What comes to information from Virunga (and other places), sometimes it happens quick, sometimes it takes time, but it´s worth to try. It´s always interesting when getting in contact with people, who have first hand experiences. When they are biologists or rangers working with animals and not in the offices etc. so much, patience is naturally needed.

Here one photo with Guhonda side by side with a tourist. Giving some idea about his size even though he isn´t standing on hind legs. Still in this camera angle it is good, that not giving any "benefits" to the man or the gorilla. Photo is from 2015.

That is a good comparative image. The gorilla is big but in this form I don't think that this specimen weighed more than 250 kg, probably even less. Gorillas are masive but those big bellies are full of gas and I remember years ago a gorilla expert saying that if the gorilla stop eating, or if eat less, the belly just dissapear.


It remaind me the record specimen:

That is true, that they usually do have a lot of intestinal gas and people visiting them have to be prepared to it, that their... "rear engines" are running constantly Wink I have no idea how much their bellies can have gas inside, of course those can protrude when a lot of gas. I guess, that extremely big looking can be combination of obesity and gas.

I've not found proof that their bellies are full of gas like you say, but they do get a lot of intestinal gas like Shadow mentioned, I just don't think it inflates them that much. As far as I'm concerned the biggest Eastern gorillas like Guhonda are still significantly heavier than 190 kg captive male Shabani.
190 kg Shabani

Guhonda

*This image is copyright of its original author

So unless there's proof that these males are so full of gas to the point it inflates them this much, then there really is no denying the obvious size difference here, and we shouldn't discard potential weights beyond 250kg either. It makes a lot of sense for an old mountain gorilla to be built like this, after all, silverback mountain gorillas can live relatively sedentary lives for 20 to 30 years and only travel short distances when they eventually move. They also consume huge quantities of vegetation daily within that time, which should mean they would gain considerable amounts of weight by the time they reach their twilight years. So we just don't know to what extent extra gas adds to their size, but if it adds anything noticeable, then Shadow's version of it makes the most sense when you include obesity.
