The king of the forest: What is a brown bear?
The basics: Who is the brown bear?
The brown bear(Ursus arctos) belongs to the bear family(Ursidae) and is one of the best-known representatives of this animal group. With a length of up to three meters (when standing) and a weight that can reach up to 600 kilograms in males, it is a real heavyweight in the animal world. Despite its massive appearance, the brown bear is a true all-rounder: it is a skillful hunter, a fast runner and an excellent swimmer.
There are several subspecies of brown bear, including the European brown bear, the grizzly bear in North America and the Kamchatka bear in Russia. Each of these subspecies has adapted to the specific conditions of its habitat.
Habitat: From the Alps to Alaska
The brown bear is an extremely adaptable species that can be found in a variety of habitats. It can be found in the boreal forests of Scandinavia, the mountainous regions of the Alps, the tundras of Alaska and even in the steppes of Central Asia.
Europe: The returnee
The brown bear was once widespread in Europe before it was decimated by human activity. Today, there are stable populations again in countries such as Romania, Slovenia and Sweden, while in Germany only isolated animals from neighboring countries are immigrating.
North America: the home of the grizzly
In North America, the brown bear is known as the grizzly. Here it mainly inhabits the mountainous and remote regions of Canada and Alaska. Its ability to survive even in barren landscapes such as the Arctic tundra is particularly impressive.
Asia: A continent of giants
Russia is home to the Kamchatka bear, one of the largest subspecies of brown bear. These bears have ideal conditions thanks to the fish-rich rivers and untouched landscapes on the Kamchatka Peninsula.
The omnivore: diet and hunting behavior
The brown bear is an opportunist when it comes to its diet. This means that it eats whatever is available - and in large quantities. In spring, it feeds mainly on young plants, grasses and roots. In summer and fall, berries, nuts and honey are on the menu. But the brown bear is also a skillful hunter, preying on small mammals, birds and even fish.
One of the most famous scenes showing brown bears foraging for food is the salmon migration in Alaska. Here, the bears position themselves at the waterfalls of the rivers and catch the jumping fish with impressive precision from the air.
Hibernation: resting during the cold season
One of the most fascinating characteristics of the brown bear is its hibernation. In the fall, the bear eats a thick layer of fat to get it through the cold months. It spends the winter in a protected den - often a self-dug burrow - in a state of reduced metabolism.
What happens during hibernation?
- Reduced heart rate: The heart rate drops from around 40 to just 8 beats per minute.
- No food or water: The bear does not eat or drink during hibernation. It draws its energy exclusively from its fat reserves.
- Birth during sleep: Female brown bears often give birth to their cubs during hibernation. The cubs suck milk and grow while the mother continues to sleep.
Behavior: Hermits and family people at the same time
Brown bears are usually solitary animals, but they also display astonishingly social behavior. Mothers with cubs in particular form close bonds and are extremely protective. During the mating season, males and females can stay together for several weeks.
The behavior of the cubs is also interesting. Bear cubs stay with their mother for about two years and learn everything they need to survive during this time: Foraging, climbing and interacting with other bears.
The brown bear and humans: a changing relationship
The relationship between humans and brown bears is characterized by respect, fear and admiration. While the bear is revered in many cultures as a symbol of strength and wisdom, conflicts caused by hunting and habitat loss have greatly reduced populations in many places.
Conservation measures and success stories
Thanks to conservation projects, there are many success stories today. In countries such as Romania and Slovenia, brown bears are protected and counted, which has led to an increase in populations. At the same time, measures are being taken to minimize conflicts with humans, for example through special bear fences or educational campaigns.
Exciting facts about the brown bear

An animal that inspires
The brown bear is far more than just a large, imposing predator. It is a symbol of the wilderness and an important part of our ecosystems. Its adaptability, its behavior and its role in the myths and legends of mankind make it one of the most fascinating animals of all.
