Summer food habits of brown bears in Kekexili Nature Reserve, Qinghai–Tibetan plateau, China:
Abstract and Figures
We documented food habits of brown bear (Ursus arctos) during summer 2005 in an important calving area for Tibetan antelope (Pantholops hodgsonii) in the Kekexili Nature Reserve, Qinghai province, China. Fecal analysis (n = 83) revealed that the plateau pika (Ochotona curzoniae) was the primary prey (78% occurrence, 46% dry weight), and that wild yak (Bos grunniens; 39%, 31%) and Tibetan antelope (35%, 17%) were important alternative prey. Vegetation also occurred in bear feces (17% occurrence). Brown bears in this region were evidently primarily carnivorous, a survival tactic adapted to the special environment of Qinghai–Tibetan plateau.

Not a wild yak but a semi-domestic adult yak, the gender is not stated in the abstract, most likely a female, nevertheless its a very good kill, about 5 times the weight of the predator:Snow leopard (Panthera uncia) predation and consumption of an adult yak in the Mongolian Altai Abstract and Figures
Snow leopards (Panthera uncia) are apex predators in Asian mountainous ecosystems, mostly hunting wild and domestic ungulates up to three times their size. Here we report on a predation event of a male snow leopard killing a semi-domestic adult yak (about five times the body weight of the predator) from the Altai mountain range in Mongolia. We used snow tracking, direct observation and camera trapping to reconstruct the hunt and monitor the consumption of the carcass. The hunt took place on a steep slope near the bottom of a high river valley and the predator was feeding on the carcass for four days, returning to the kill site once per day with an average feeding bout of 72 min. We also documented inter-specific and intra-specific kleptoparasitism, as common raven (Corvus corax), red fox (Vulpes vulpes) and another male snow leopard scavenged on the prey remains. This study confirms that even the adults of large domestic ungulates are vulnerable to snow leopard predation, and highlights the need to better understand the importance of kleptoparasitism in the ecology of this elusive predator.

The only subspecies of brown bear living up in the yak's domain is the Tibetan brown bear, also called the blue bear ( Ursus arctos pruinosus ). Thus far we have not found any source of information on this bear's size other than "small". They are very likely within the same size range as the Himalayan brown bear or red bear ( Ursus arctos isabellinus ) which places them on average within the 200-pound range. So, even though the blue bear is said to have a disposition similar to the barren ground grizzly, he is no threat to a yak.

Reply #5:
Am pretty sure that the Himalayan brown bear (Ursus arctos isabellinus) also ranges with Wild yak.

The Himalayan brown bear will not bother the yak at all. The Tibetan blue bear might kill a calf occasionally.

A prime male yak is untouchable

And as reply #1 shows, they have found wild yak remains in 39% of the feces of the Tibetan blue bear, although as we already know, this method is not reliable to prove predation as the bear could have just eat the animal, not killed it. Anyhow, if some wild yaks are killed, they are most likely calfs or subadult females.

A prime male yak is untouchable Brobear has around 5/6 historic phrases. Well, this would be your first one. Great phrase bro. Hell yeah!

This subspecies doesn't get that huge, we dont have the average weight, but i would be surprised if the largest specimens reached 450 lbs. Also, this is the most passive brown bear subspecies.

Really? Google says Himalayan brown bears can weigh 550 kg. Well these could be either unconfirmed or freak individuals

Really? Google says Himalayan brown bears can weigh 550 kg. Well these could be either unconfirmed or freak individuals You are probably going by this site here, but its a kids site:
kidadl.com/animal-facts/himalayan-brown-bear-facts
Like i said above, we have no scientific weights for this subspecies, so we have to go by what we do have:
For example, Fandom states the average is 135 kg (297 lbs)
"They have thick reddish-brown fur and males are larger than females, with an average length of 1.9m and weight of 135kg, in comparison to the female averages of 1.6m and 70kg."
planetzoo.fandom.com/wiki/Himalayan_Brown_Bear
Wiki and the Bear conservation site both state this bear reaches 7 feet long, to reach 550 kg (1212 lbs) the bear would need to be at least 8/9 feet long.
This is one of the smallest brown bear subspecies on average (along with the Syrian brown bear).

Perhaps the writers of the Jungle Book movie got their inspiration from that kids side. Since their Baloo (who is a Himalayan brown bear) is unusually large.

www.coniferousforest.com/himalayan-brown-bear.htm The Himalayan brown bear is a species of brown bear found in the Northern Himalayan mountain ranges. It is the largest carnivore in its habitat. Its population numbers have been on a constant downswing because of loss of habitat. Human persecution for their claws and fur is another important reason behind this bear’s falling numbers. Himalayan brown bears are mostly active throughout the day, but have their meals in the morning and evening, and spend the rest of the day mostly in thick vegetation. They are solitary, but the territories between two Himalayan brown bears have been seen to overlap. They are one of the most terrestrial of bears. Size: Males – 5 ft to 7 ft 3 in (1.5-2.2 m); Females – 4 ft 6 in to 6 ft (1.37m-1.83 m) Weight: Males – 298 lb (135 kg); Females – 150 lb (70 kg) Color: Reddish-brown to sandy *I have never found any weights confirmed for the Tibetan blue bear. I doubt that they are any bigger than the Himalayan red bears. These bears pose no threat to an adult yak.

I’m not sure about this. But maybe the Tibetan blue bear can kill a yak 3 times it’s size like the Arctic grizzly does to musk ox
