Grizzly Bear diet overview
Grizzly Bears (Ursus arctos horribilis) are best summarised as Omnivore. Anatomy and habitat (Forests, meadows, and mountains) decide whether they hunt, graze, filter, scavenge, or mix strategies across the year.
How grizzly 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.
Grizzly Bear role in the food web
As consumers in their food web, grizzly bears move nutrients and influence prey or vegetation.
Feeding and human conflict
Never feed wild grizzly bears. Habituation raises injury risk and can lead to lethal management. Captive diets must match species needs, not generic pet food rules.
Diet and feeding
Despite their fearsome reputation, grizzlies are omnivores that eat far more plants than meat. They feast on berries, roots, nuts, insects, fish, and carrion, and famously gather at rivers to catch salmon during the run. In autumn a grizzly may eat for up to 20 hours a day, packing on fat before winter.
Hibernation
Grizzlies spend the harshest months in a den in a state of deep dormancy, living off the fat reserves they built up in autumn. Females give birth during this time, and tiny cubs nurse and grow in the den before emerging in spring. A bear's heart rate and metabolism slow dramatically while it sleeps.
