Grizzly Bears - Seasonal Survival

As winter nears, bears prepare for hibernation, a long sleep to survive scarce food conditions. Grizzlies' diets change with the seasons: they eat roots and grass in spring, red meat in May, and salmon in midsummer. In autumn, they consume clams and berries to gain weight for hibernation. During hibernation, bears burn calories and can lose a third of their body weight. In spring, they emerge focused on finding food until the next hibernation cycle.
