Higuma Behavior and Diet in the Rausu Region

To truly appreciate the brown bears of Mount Rausu, it's important to understand their behavior and dietary habits. These powerful animals are incredibly intelligent and adaptable, with behaviors shaped by their environment and the availability of food. Their activity patterns are largely dictated by the seasons, with a distinct period of hibernation during the winter months. Understanding their seasonal behavior is key to avoiding encounters and ensuring their well-being.

Seasonal Rhythms: Hibernation and Activity Cycles

Brown bears in Hokkaido typically enter hibernation in late autumn or early winter, seeking shelter in dens dug into hillsides or under the roots of large trees. During this period, their metabolism slows dramatically, allowing them to survive for months without food or water. The length of hibernation varies depending on weather conditions and individual bear's fat reserves. They usually emerge from their dens in the spring, lean and hungry, ready to replenish their energy stores.

Upon emerging from hibernation, bears actively seek out food sources. Their diet at this time consists primarily of vegetation, such as new shoots and grasses, as well as any available carcasses from animals that did not survive the winter. As summer progresses, their diet diversifies to include berries, insects, and other small animals. The availability of berries, in particular, plays a crucial role in their overall health and reproductive success. Autumn is a critical period for brown bears as they prepare for winter. They focus on consuming high-calorie foods, especially salmon, to build up fat reserves. The Shiretoko Peninsula is renowned for its salmon runs, providing an abundant food source for the bears during this time.

Dietary Diversity: From Salmon to Berries

The diet of brown bears in Mount Rausu is remarkably diverse, reflecting the richness of the surrounding environment. Salmon is a keystone food source, especially during the autumn spawning season. Bears congregate along rivers and streams, skillfully catching salmon to fuel their bodies for the upcoming winter. This dependence on salmon highlights the importance of maintaining healthy river ecosystems and ensuring the sustainability of fish populations.

Berries are another crucial component of their diet, particularly during the summer and early autumn. Various berry species thrive in the region, providing bears with essential vitamins and energy. They also consume a variety of vegetation, including grasses, herbs, and roots. Insects, such as ants and grubs, provide an additional source of protein. Occasionally, brown bears may prey on deer or other mammals, especially if they are weak or injured. Scavenging is also an important aspect of their feeding behavior, as they readily consume carcasses of dead animals. This diverse diet underscores their adaptability and their integral role in the ecosystem.

Staying Safe in Brown Bear Country: Essential Guidelines for Visitors
