Quick answer
Brown Bears feed on berries, fish, roots, insects, and carrion, adjusting with season, age, and what is abundant in Forests, mountains, and tundra across the Northern Hemisphere. That label is a preferred pattern, not every item an individual might sample.

Brown Bear diet overview
Brown Bears (Ursus arctos) are best summarised as Omnivore — berries, fish, roots, insects, and carrion. Anatomy and habitat (Forests, mountains, and tundra across the Northern Hemisphere) decide whether they hunt, graze, filter, scavenge, or mix strategies across the year.
How brown bears find food
Energy-rich foods are prioritised when available; lean seasons force broader diets or longer travel. Young animals may eat different items or receive food from parents.
Brown Bear role in the food web
As consumers in their food web, brown bears move nutrients and influence prey or vegetation.
Feeding and human conflict
Never feed wild brown bears. Habituation raises injury risk and can lead to lethal management. Captive diets must match species needs, not generic pet food rules.
Diet and seasonal feeding
Brown bears are omnivores whose diet shifts with the seasons. In spring they graze on sedges and roots; summer brings berries and insects; autumn is dominated by hyperphagia as bears pack on fat before winter. Coastal bears gather at salmon runs, while inland populations rely more on plants and small mammals.
Hibernation and reproduction
Pregnant females enter dens in late autumn and give birth during hibernation, usually to one to three cubs that nurse and grow inside the den until spring. Hibernation slows heart rate and metabolism dramatically, allowing bears to survive months without eating, drinking, or passing waste.
