All about Gaur (Bos gaurus)

[Shadow]

Short standoff between gaur with calves and tiger before dispersion. If these people filming could decide what they try to film and then find some way to keep camera steady :) Also keeping mobile phone in horizontal position would make it possible to film wider perspective... maybe we could have seen both animals in same time there and how they behave. Still interesting to see a glimpse from interactions of these amazing animals. These situations where two animals are measuring up each others trying to decide what to do are always fascinating to watch.

I wonder if this is from same incident, uploaded same time, but looks like a different gaur. Also guarding to different direction.... but sometimes there are footage from same incident and other one is for some reason like mirror image.

A big gaur...

Gaurs are in that way interesting, that there seems to be controversiality about weights. Or at least it is a bit unclear, that how big they are in different countries. Some sources say, that in India gaurs aren´t as heavy as in some other places. 

Like this quote:
"Gaur is the tallest living oxen and the second heaviest.  The gaur bull weighs 600-1000 kg and stands 1.6 to 1.9 m of shoulder height whereas cows are about 10 cm shorter than the bull and weigh about 450 to 800 kg."

https://www.researchgate.net/publication/265096609_Gaur-_A_wild_cattle_in_grave_peril

Also this: 
" Adult gaur bulls weigh 600-940 kg and stand 1.6 to 1.9 m at shoulder [2]. The adult cows are about 10 cm shorter in height [3] and weigh about one fourth less than the adult males [4]."

Then there is this:

" On average, males stand about 180-190 cm at the shoulder and females about 160-170 cm. Weight of males ranges from 1000-1500 kg."

https://www.researchgate.net/publication/234100426_Modelling_of_habitat_Suitability_for_Gaur_Bos_gaurus_using_multiple_logistic_regression_remote_sensing_and_GIS

I´ve seen some study saying, that in India gaurs wouldn´t be the heaviest one, but heaviest were in some other country, but I don´t now remember what study it was, have to look closer when a bit more time. But that could explain why 2 studies give for gaurs in India (males) that weight range from 600-1000 kg and then that last one talking about all gaurs give bigger numbers.

I also remember seeing one study etc. where was average weight for gaur bulls something like 830-840 kg, which is naturally a lot. Still for me it looks like, that most of gaurs we see in photos are more likely less than 1000 kg than close to 1500 kg. People tend to like see big things and of course already a bovine over 800 kg is massive. But maybe many see there almost double of that based on it, that mixing up exceptional weights to averages as it happens with many other animals too. Reply

One source, which should be quite good.

Quote: 
"The gaur is a massively built bovine with an average weight of 650 to 1,000 kg. The occasional large bull can weigh up to 1,500 kg. The tallest species of wild cattle, gaur reach 165 to 220 cm at the shoulder. Males are about one-fourth larger and heavier than females. Gaur are among the largest land animals, surpassed only by elephants, rhinos, hippopotamus, and giraffe."

So again, normal range in between 650-1000 kg and only occasionally more than that up to 1500 kg.

Indian gaurs are not really a homogeneous lot... From what can be assessed from photographs the ones  living in Central India are clearly smaller & lighter than the one from north/northeast, with the one from South India easily being the largest & bulkiest.

The gaurs from Indochina are atleast of same size as the ones living in adjoining parts of northeast India, maybe more. Reply

Yes that is of course logical, borders are where they are but environments are that relevant thing when thinking about possibilities of different populations. Reply

there is no way to tell unless there is solid findings or a very observant person has seen gaurs from various parts to make any distinction in weights, From photos it can be seen that Gaurs from southern india looks like the best specimen as far as photos go. they have the biggest dewlaps and biggest horns but there is no way to tell if they are the largest based solely on the photo. Photos sometimes give false impression. By many accounts central Indian gaurs are said to be slightly lesser in built, while those from terai -nepal and north east india is probably the least known and from photosit is quite clear that they lack colossal dewlaps but that's that. i have never seen gaur ( i could have analysed it against wild water buffalo) to make any comparison and how it would stack in mass probably those are pretty equal gaur taller thinner buffalo shorter wider. Example of this kind of geographic variation within the same subspecies can be seen also in Asian Elephants, Elephants of terai region are said to be huge, that they dwarf other Asian elephants from mainland but even then Wild elephants of Chitwan region (Central Terai) are not so humongous while those from Bardia and adjacent Indian side (Western Terai) are said to be the biggest race of wild elephant in Asia, bigger than those from Srilanka which again is one of the largest subspecies and would dwarf other Elephant except western Terai.
