This thread is for accounts which involve interactions between tigers that overlap their territory with sun bears.

/\ This seems to be a once in a blue moon account although this story is told by a native. Yes, it's a great story and possibly true. But, I agree with what you are hinting at. This event remains unconfirmed. We cannot claim it as FACT just because we like the ending, the way that the big cat fanboys do. |

Having said all this, i believe absolutely all accounts of bears killing or defeating tigers, wild or captive. |

SUN BEAR AND SUMATRAN TIGER KILL EACH OTHER IN A FIGHT: took place out in the jungle. There was simply no person of any authority present to confirm the incident. I believe it to be true, but I will not claim it as "confirmed". It's rather like the more recent incident of the tiger killed by a sloth bear. The evidence was pretty strong showing that the tiger was killed by a bear; but simply not enough to "stand up in court to convict the bear as the killer." The evidence there was much stronger than anything the tiger fanboys have found which they claim to be "confirmed" cases.

"...Therefore, I would postulate that the majority of the tiger’s prey consists of pigs and muntjac, 2 of the largest and most locally available prey species, supplemented by whatever else is available as needed. It may be argued that sun bear is not a typical prey for tigers and the evidence in this study merely suggests opportunistic predation. Sun bear was relatively common, second only to muntjac (Table 3-5) and it was also fairly widely distributed at an average estimated occupancy of 62% (Table 3-7), presenting ample opportunities for predation. Campell (1894), Clutterback (1894), and Lane (1904) reported that tigers killed other bear species larger than sun bears. Clearly not all sun bears are vulnerable to predation, but the same can be said for aggressive male wild boar that can weigh up to 127 kg (Khan 1992). The 3 sun bears killed by tigers were adult animals although dentition suggested that 1 was very old..."

/\ Great find bro. Just like sloth bear, brown bears and black bears, indeed sun bears, even females and young ones, are rarely hunted. Bears arn't deer or boar. Even smaller, they are still dangerous.

Sun bears are one of the most least studied bears along with the spectacled bears. Intereactions with other predators arn't well known and most of its aspects are mysteries and ecology filled with speculations.
"The Malayan sun bear Helarctos malayanus is one of the least known bear species in the world. Even basic biology such as food habits, activity and ranging pattern and reproductive biology are unknown."
onlinelibrary.wiley.com/doi/pdf/10.2981/wlb.00351
However, there are some studies working on them and revealing some data. The thing i want to discuss that do tigers effect sun bear's behaviour as are leopards heavily being effected by tigers. I am simply excluding tigers predation over sun bears since its a rare thing to happen and it has virtually no effects on them. Other than that, is noticed. Starting with the bears treeing in nest at tree tops.
"In addition, the presence of big cats that share the same habitat with sun bears in Sumatra and the Asia Mainland, such as tigers (Panthera tigris) and leopards (Pantrera pardus), may cause sun bears to seek safer ground for bedding. Although the interaction between these species has rarely been reported, these big cats pose a significant threat to the life of this small bear. Lim (1998) suggested that the only likely enemies of the sun bear are a hungry tiger or panther (leopard). Van Balen (1914) (in Meijaard 1999b) reported a fight between a Sumatran tiger (P.t. sumatrae) and a sun bear in southern Sumatra. This kind of interaction may explain why reports of nest building behavior of sun bears in the forests (except plantation and gardens) were often from Sumatra and Asian Mainland, but not Borneo where these two large cats are absent. Clouded leopards are present in Borneo but this is a smaller cat and may be less of a threat to sun bears".
Its wise for the bear to tree up since compared to those big cats, its a small bear and is no match. However, note that sun bears mostly spend time in their nests while sleeping, when they are most vulnerable. They mostly spend time eating fruits and honey; and these nest serve them as tables for eating food rather than entirely of safety ground. Instead, the nests are more oftenly used for food habits than safety reason. Young specimens are more likely use them as for safety rather than adults.
"Young bears of most species climb trees as a refuge from predators. Andean bears of South America and Sun bears of South-east asia appear to be more arboreal, but this behaviour is more related to their food than threats of predation".
www.google.com.pk/books/edition/The_Encyclopedia_of_Applied_Animal_Behav/vrueZDfPUzoC?hl=en&authuser=3
Fruits and ants their primary food is found on trees, while honey as their favourite food is also on canopies which make them to spend most of their time in trees.

Sun bears seems not to fear tiger presence since despite of predatory threats (which are commonly rare) since adults seems to fight off tigers.
"Sun Bears are fierce. They will fight off tigers, leopards and large pythons when threatened."
taronga.org.au/animals/sun-bear#:~:text=Sun%20Bears%20are%20shy%20and,and%20large%20pythons%20when%20threatened.
And for such reason, they have a very loose and elastic skin on their body especially around neck to protect them from ambush attacks.

sunbears.wildlifedirect.org/2012/03/13/look-violent-but-completely-harmless-the-integration-of-debbie-with-mary-and-fulung/
And, tigers due to this bear's fearsome attributes, are very recultant to attack them face on as in this video.
Not even this, even the largest of the tigers, the Bengal tiger, avoids them!
"Tigers will avoid sun bears, and would sneak and ambush sloth bears". (Bear biologist, Gary Brown)
books.google.com.pk/books?id=L0ggAQAAIAAJ&q=sun+bears+avoid+tiger&dq=sun+bears+avoid+tiger&hl=en&newbks=1&newbks_redir=0&source=gb_mobile_search&authuser=2&sa=X&ved=2ahUKEwibltasofz9AhVRU6QEHQ0cCP4Q6AF6BAgIEAM
So as, seen from overall data, both sun bears and tigers try to avoid eack other, as sun bear's avoidence from being preyed and tiger's avoidence by being injuried (injuries can be fatal for hunters). Sun bears don't fear tiger presence and would mostly tree up due to their basic food rather not predation fear though young bears might tree a bit more for avoidence than adults. However, thats not all. Is there any more proof that they arn't subordinate to tigers? Yes, there is! And that proof come from the evidence of daily activity patterns. What is that excatly? First we need to understand it.
Diurnal and nocturnal are two term which applies to animal activity as the former means "active mostly during daytime" while the latter means "active mostly during night and dark hours". In animal world, dominant predators are diurnal and nocturnal (mostly nocturnal) whilst the subordinate predator to them shapes his activity by becoming more diurnal in order to avoid conflict.
"In the carnivore community, dominant carnivores are mainly nocturnal and twilight, while secondary competitors perform diurnal activities to avoid disturbing suppression from the dominant species. For example, leopards (Panthera pardus) are more active diurnally than tigers (Panthera tigris) in the Changbai Mountains, China."
www.mdpi.com/2076-2615/12/10/1262#B78-animals-12-01262
Ussuri black bears also avoid conflict with Ussuri Brown Bears by being more dirunal than the latter. A perfect example is to see that in South asia and South east asia, areas where tigers were formally absent, leopards had a diurnal and nocturanl activity, however when nocturnal tigers were introduced, the submissive leopards managed their daily pattern as more diurnal than before to avoid tigers.
"Before the introduction of tigers or in areas where tigers are not present, leopards are nocturnal and morning and evening, while after the reintroduction of tigers or in areas where tigers are already present, leopards become diurnal to reduce overlap with tiger activity (Mondal et al, 2012; Steinmetz et al, 2013)."
www.google.com/url?sa=t&source=web&rct=j&url=https://www.biodiversity-science.net/EN/10.17520/biods.2020359&ved=2ahUKEwjPoo3Kqfz9AhW0hv0HHWikArAQFnoECAsQAQ&authuser=1&usg=AOvVaw0ZVffZoUzFimtQwkl8EQ3C
Now lets compare this tiger-leopard to tiger-sun bear activity pattern in malaysia. As generally, like all tigers, Malayan tigers are nocturnal.
"Tigers are mostly nocturnal".
www.google.com/url?sa=t&source=web&rct=j&url=https://tulsazoo.org/wp-content/uploads/2015/08/MALAYAN-TIGER.pdf&ved=2ahUKEwjFy7K9qvz9AhUdgf0HHfgBBcYQFnoECAoQBg&authuser=1&usg=AOvVaw0TVCRUbVEq2a1KlYlLsAVV
"Tigers are nocturnal cats that spend most of the day sleeping and moving around their territory before searching for prey at night,"
www.savethemalayantiger.com/get-to-know-our-malayan-tiger-habitat/
While tigers are nocturnal, and so are malayan sun bears who show most activity not only daytime but also at night for finding food.
From National Geography:
"Ironically, sun bears are nocturnal. They lumber through the forests by night, snacking on fruits, berries, roots, insects, small birds, lizards, and rodents."
www.nationalgeographic.com/animals/mammals/facts/sun-bear#:~:text=Ironically%2C%20sun%20bears%20are%20nocturnal,birds%2C%20lizards%2C%20and%20rodents.
"Sun bears are nocturnal, using their keen sense of smell to forage for termites, beetles, earthworms, and bees and ripping open trees and insect nests with their sharp claws."
www.nathab.com/know-before-you-go/asia-the-pacific/borneo/wildlife-guide/sun-bear/
"Sun bears are primarily nocturnal, but daytime activity has been observed in this species."
malaysianwildlife.org/malayan-sun-bear-helarctos-malayanus/
Sun bears basically show both diurnal and nocturnal acitivity in finding food. Its nocturnal behaviour in tiger's territory means that, unlike leopard which becomes more diurnal in tiger presence, the sun bear does fears tigers and move normally at the time when tigers are most active. If sun bears were subordinate to tigers, so they would be more diurnal than before, but its not the case.
So overall, in sun bear and tiger intereact, both respect and avoid each other.

Sun bear and tiger intereactions conclusion:
1#. Tigers, even the Bengal tiger, would avoid sun bears. (Gary Brown)
2#. Sun bears would fiercely fight off againat tiger. (Taronga Conservation Society)
3#. Sun bears have a very loose skin as a defense against tiger ambushes. (Sunbears.wildlife.org)
4#. Sun bears would sometimes scavenge on tiger kills. (Champion)
5#. It may be argued that sun bear is not a typical prey for tigers and the evidence in this study merely suggests opportunistic predation. (Burnham, David W. Macdonald)
6#. Sun bears tree up most in those regions where tigers are present. (Lim) However, mostly young bears climb trees to avoid predators as Sun bear aboreal habit is due to food rather than predatory reasons. (The Encyclopedia of Applied Animal Behaviour by D. S. Mills, Jeremy N. Marchant-Forde)
7#. Unlike leopards, which become more diurnal in tiger areas ¹ to avoid tigers which are nocturnally active ², the malayan sun bears shows a lot of noctural activity ³ meaning they don't fear malayan tiger presence and freely search for food. (Mondal and Steinmetz ¹, Savemalayantiger. org ², National geographic and MalayanSunBearPDF ³)
