Bears usually eat a variety of plants, berries, and insects on a daily basis. Contrary to popular belief, they are not blood-thirsty carnivores. Bears are omnivores, meaning they eat both meat and plants. They are usually an apex predator, at the top of the food chain in their environment. Because of this, they rarely have to hunt or forage for food, and are simply able to steal food from smaller animals.
During the winter, bears don't eat anything. They spend the fall months storing up as much fat as possible for the winter months. Then during the winter, they hibernate the duration of winter. In the spring, they wake up very hungry and immediately begin foraging for food again.
