At first glance, brown bears may appear larger and heavier than tigers. Tigers, on the other hand, are ferocious carnivores and they often prey on larger animals such as bears, crocodiles or leopards. But have they ever encountered a brown bear? Let’s find out!
But first, let’s discuss some basic details about these two animals to get an idea of their size and weight.
What is a tiger?
Tigers are the largest cats in existence and are known for their orange fur, white underbelly and dark vertical stripes. They are considered the top predators in their habitat, preferring to feed on ungulates. Male tigers typically measure about 8.1 – 12.8 feet long and weigh up to 660 pounds, while females are smaller and lighter, measuring 6.5 – 9 feet long and weighing up to 368 pounds.
Tigers are nocturnal predators, but if they live in uninhabited areas, they will usually hunt during the day. They ambush their prey and use their power to throw them off balance. They are very fast, reaching speeds of 30-40 mph. However, they cannot run very fast, so they usually ambush their prey at close range. When they hunt large animals, they grab the prey with their forelimbs, bite the throat of the prey, and knock it to the ground.
What is a brown bear?
Brown bears are large bear species that live in North America and Eurasia. At first glance, brown bears may appear larger than tigers, mainly because of their thick fur. However, most are about 4 – 9 feet long and can weigh up to 400 pounds for males and 298 pounds for females. If we compare their size and weight with the average size and weight of a tiger, orange cats are bigger and heavier.
Brown bears are not considered active predators. They eat just about anything they stumble upon, but rely mostly on flowers, fruit, acorns, and mushrooms. Some brown bears eat salmon. When hunting other animals, brown bears tend to choose smaller prey, pin it to the ground, bite and eat it alive. If they hunt large prey (which is rare), they will strike the prey with their forearms, breaking its neck and back, and killing it.
Because they are so big and strong, brown bears can withstand the confrontation of almost any predator. However, in the encounter with the Siberian tiger, they took a step back. But let’s not get too excited; we’ll talk about that further in this article!
Where did the tiger kill the brown bear?
Most brown bears live in Russia, the United States and Canada. On the other hand, most tigers live in remote areas of South, Southeast and East Asia. So, where do their paths cross? In Russia!
Siberian tigers live in Primorsky Krai, the Russian Far East, and extend as far south as the Khabarovsk Krai. Their population further expanded to the Greater Khingan Mountains.
So it’s only natural that brown bears and Siberian tigers might have a chance encounter in eastern Russia.
Are brown bear vs Siberian tiger confrontations common?
Confrontations between brown bears and Siberian tigers are more common than you might think. In fact, Siberian tigers actively prey on brown bears. Even brown bears sometimes seek out Siberian tigers to poach prey. While both are large and strong predators, tigers are better at killing brown bears. After all, that’s what they do every day. Brown bears, on the other hand, rarely hunt large game and their hunting skills are underdeveloped. As we mentioned, they would rather follow the Siberian tiger’s trail and steal its prey than face it.
Of the 44 documented encounters between brown bears and Siberian tigers, 20 ended in fights. This shows that neither likes the other. In half of these confrontations, brown bears were killed. In 27 percent, brown bears killed tigers, and in 23 percent, no winners survived.
Dr. John Goodrich, director of the Panthera Tiger Program, recalls how he “almost” saw a tiger kill a brown bear. Decades ago, Dr. John Goodrich was tracking Dima, a 455-pound male tiger they had previously captured. They noticed the tigers were moving randomly in areas where people lived, so Dr John Goodrich tried to make sure everything was ok. He was following the tiger’s tracks through the spring snow, and as he approached the edge of the steep bank he noticed that the tracks were starting to move closer together. surprise! On the embankment lay a half-eaten big brown bear.
Over the next few years, the tiger killed a few other bears, though not as successfully as the first time, as the bears fought to survive.
Why do tigers prey on brown bears?
Tigers can easily eat almost anything they want. So why would they bother killing brown bears – a powerful creature that can fight back? In addition to brown bears, Siberian tigers also hunt Himalayan bears, according to the study.
Some scientists believe this may have occurred due to competition and revenge. Many Siberian tigers may hunt brown bears because the latter prefer Siberian prey. We’ve already mentioned that brown bears often follow tiger tracks to access their prey because it’s easier than hunting. So maybe tigers just want to protect themselves, or maybe they prefer to kill large prey that can be eaten for days.
What other animals do Siberian tigers eat?
The study of the dietary habits of Siberian tigers in Sikhote-Arinzapovinik and the Russian Far East revealed that they preyed mainly on Manchurian elk and Ussuri wild boar. They also hunt livestock, dogs, and occasionally wolves.
Since Siberian tigers were nearly extinct many years ago, with only 40 left in the wild, their relationship to other wildlife is critical to conservation. Today, thanks to conservation efforts, there are about 400 Siberian tigers. However, this comes with significant sacrifices. Their numbers have plummeted as tigers prey on native wolves. Therefore, scientists are currently trying to track the footprints and habits of Amur tigers to prevent the extinction of other species, including brown bears.
I am broadly interested in how human activities influence the ability of wildlife to persist in the modified environments that we create.
Specifically, my research investigates how the configuration and composition of landscapes influence the movement and population dynamics of forest birds. Both natural and human-derived fragmenting of habitat can influence where birds settle, how they access the resources they need to survive and reproduce, and these factors in turn affect population demographics. Most recently, I have been studying the ability of individuals to move through and utilize forested areas which have been modified through timber harvest as they seek out resources for the breeding and postfledging phases. As well I am working in collaboration with Parks Canada scientists to examine in the influence of high density moose populations on forest bird communities in Gros Morne National Park. Many of my projects are conducted in collaboration or consultation with representatives of industry and government agencies, seeking to improve the management and sustainability of natural resource extraction.
