Bear kleptoparasitism over cats

[Montezuma]

In this thread we are going to see scientific data showing that bears are kleptoparastises of big cats. This thread is going to cover bear kill taking from cats including

1. Brown bear over tiger
2. Sloth bear and black bear over leopard
3. Black bear and grizzly bear over cougar
4. Black bear and sloth bear over tiger

We will first start from,

"Brown bear kleptoparasite of the Siberian tiger".





From Ivan Seryodkin, the Siberian tiger project leader.


“Despite the fact that his diet is dominated by food of plant origin, brown bear is the largest ground-based predator before the Far East. This beast is capable to obtain practically all form of the mammals: from the mouse-like rodent to the tiger myshevidnyh.”

“In the far of east are known the cases of the selection of victim by brown bearsin Amur tiger and leopard. In of the Sikhote-Alin preserve before 35% of cases of the victim of tiger they were obtained by the brown bear as a result of selection from owners. In this case the tigers departed bases on their victim entirely, or alternately divided them with the bear.”

([Seryodkin] and other, 2005). (Seryodkin at el, 2005)

Now this one is from Dale Miquelle, director of WCS.


“It is clear that brown bears reap greater benefit from the presence of tigers because tigers killed animals - a source of protein food for bears. Therefore, not surprisingly, bears commonly use this source, even if it requiresa direct clash with the tigers. Tigers, it seems to unable to prevent adult male brown away from their food”.

Wow, a Huge brown bear displaced a male amur tiger from its boar kill, the tiger ran away without a fight. Interview from a hunter.

“In November that year I witnessed following event. Around the river started coming a brown bears, they didn't go to hibernation. One of them found a way how to eat tasty pork without making any hunting efforts. He got a tiger's traces. And so the tiger kills a boar than the bear comes, chase away the stripe and appropriate the carcass. And the traces of that bear were gigantic. Me and my friend both have choose size No 45 and we together placing our feet on the bear trace couldn't cover all the trace. Tiger without any fight gave up and go away."

"Adult male brown bears are stronger and force aways tigers to give up their prey. Interesting."


tigers are pure predators, as long as the bears' ration concists of meat only by 15%. Bute male bears, being stronger, sometimes can force tigers to give up their pray. Only once in 5 years during monitoring in the reserve Juravliny a case was fixed when tiger named Boris attacked a bear.




Эти два гиганта Уссурийской тайги редко взаимодействуют друг с другом, но все же, иногда встречаются... Они не являются прямыми конкурентами, поэтому редко переходят дорогу друг другу - тигр специализируется на мясе, а у медведя в годовом рационе лишь 15% животной пищи.

Но медведь может пойти отнимать добычу у тигра, особенно, если бурый- крупный самец. Он не против полакомиться лосем, кабаном, изюбрем... А если ,вдруг, медведь завалил добычу, то тигр вряд ли пойдет её отнимать, так как медведь будет яростно защищать ее. За 5 лет мониторинга, который мы проводим в заказнике "Журавлиный", мы зафиксировали единственную охоту тигра на медведя, отличился тигр Борис. Но все же, бурый медведь не является излюбленной добычей тигра, уж очень он силен, проворен и быстр! Помочь Центру-

"These two giants of the Ussuri taiga rarely interact with each other, but nevertheless, sometimes they meet ... They are not direct competitors, therefore they rarely cross the road to each other - the tiger specializes in meat, and the bear has only 15% of animal food in the annual diet. But a bear can go to take away prey from a tiger, especially if the brown is a large male. He is not against eating elk, wild boar, wapiti ... And if, suddenly, the bear has filled up the prey, then the tiger is unlikely to go to take it away, since the bear will fiercely defend it. For 5 years of monitoring, which we have been conducting in the Zhuravliny reserve, we have recorded the only tiger hunt for a bear, the tiger Boris distinguished himself. But nevertheless, the brown bear is not the favorite prey of the tiger, he is very strong, agile and fast! Help the Center-"

From other biologists saying that brown bbears also track tigers for kill.

"2006 Relationship of Bears and Tigers in the Russian Far East Ivan Seryodkin1, Yuri Petrunenko1, Dale Miquelle2, 1Pacific Geographical Institute, FEB RAS, Vladivostok, Russian Federation; 2Wildlife Conservation Society, New York, NY, Contact: [e-mail] In the southern Russian Far East, brown bears (Ursus arctos) and Asiatic black bears (U. thibetanus) co-exist with Amur tigers (Panthera tigris altaica). In the Sikhote-Alin Reserve the relationships between these three species were studied in 1992-2013 during extensive telemetry and snow-tracking efforts. Bears often fed on Amur tiger kills. Of the 353 tiger kills we found during the non-denning period for bears (April-November) 62 kills (17.6%) were used by bears including 37 (60%) brown bear, 9 (14%) by Asiatic black beer and 16 (26%) of uncertain bear species. The proportion of tiger prey scavenged by bears is likely higher than what our data indicate, since utilization by scavengers was not always complete when we visited kills. Often bears fed on kills after tigers abandoned them. However, in at least in 8 cases (12.9%) bears displaced tigers from a kill, and in 7 cases (11.3%) both tigers and bears utilized a kill during the same period. Analysis of prey items revealed that bears represent 3.4% in the diet of tigers in the non-denning period (1.7% for each species of bears). In 44 recorded encounters between tigers and bears, the tiger initiated contact in 12 cases while the bear initiated contact in 8 cases, while in all other cases the individual initiating contact could not be determined."

“Adult brown bears can match wolf packs and large felines, often driving them off their kills. A seed disperse and predator, it plays an important role in the ecosystem”.

"Some bears have been known to seek out tigers for kills emerging from hibernation. (Matthesien and Hornocker, et al 2001)."

From the same source above:

kleptoparasitism is the most frequently reported interaction between brown bears and felids.

Large felids mainly hunt ungulates, which may take them several days to consume. Extended handling time increases the potential for carcasses to be usurped by the scavenging bears.

It has also been suggested that scavenging by bears may have been an important factor in shaping felid patterns of prey selection toward smaller prey and results in consequent morphological and behavioral adaptations of predators during the evolution of some felids, like the genus lynx.

Have you any proof about the tiger being male (or adult at least)? Also this should also be included in bear killing or defeating tigers thread anyway.
