The grizzly bear, a subspecies of the brown bear, is a smaller, lighter version of the sometimes lovable and often frightening mammal.
People speculate that massive animals weighing between 700 and 1,700 pounds are walking the forest trails, waiting to kill anyone who viciously crosses their path, but this is far from the truth. Contrary to what many might assume, what grizzly bears eat is 90% vegetarian!
Who is competing with grizzly bears for food?
In North America, grizzly bears most often compete with wolves for food and prey. Although bears consume far more vegetation than wolves, they are two notable predators of Yellowstone National Park. However, humans are the real predator for both of these animals.
What do grizzly bears eat?
Grizzly bears eat a diet of 90% plants, but they are incredibly adaptable in their diet and eat everything from salmon to marine mammals, insects, berries and roots. What grizzly bears eat depends on the time of year and what is available in that particular region. For example, when grizzly bears wake up from hibernation in the spring, there may not be many options as the snow melts and the buds begin to bloom, but the grizzly always finds a way out.
Grizzlies often scavenge in trash after hibernation, finding carrion such as dried carcasses of fish and other dead animals left over from the winter.

How does the grizzly bear’s diet affect other species?
Due to climate change, the extinction of white pines has severely impacted one of the grizzly bears’ staple foods, forcing the bears to leave their shelters and seek food elsewhere.
Often grizzlies migrate through ranches and farms, resulting in the death of livestock and creating a somewhat villainous relationship between humans (livestock owners) and the grizzlies.
How much do grizzly bears eat?
Grizzly bears are grazing animals and eat more plants, berries, and insects than anything else. In the fall, when berries are plentiful, grizzly bears can eat 200,000 a day!
In the late summer months, butterflies abound at high altitudes in the Rocky Mountains, which is great for grizzly bears. These big guys can eat up to 40,000 moths a day! Regardless what kind they eat grizzly bears can eat up to 90 pounds of food a day!
Are grizzly bears dangerous to humans?

What do different types of grizzly bears eat?
All bears eat what they can find, but this can greatly depend on what is available. For example, bears by the oceans feed on dead whales and seals that are washed ashore, while bears by fresh streams, lakes and rivers wait in the water to catch fatty fish such as salmon.
Coastal grizzlies will take full advantage of any marine life this particular body of water has to offer.
How do grizzly bears hunt?
Grizzly bears are omnivorous and feed mainly on plants, fruits, and animal protein. Grizzly bears combine scavenger, carnivore, and herbivore, using their adaptable nature to combat hyperphagia as they find food to gain as much fat as possible during the long, cold winter months.
Grizzlies often eat already dead things and small rodents or insects that they dig up from the ground or rotting logs. Sometimes grizzlies look for and eat newborn animal calves.
What do grizzly bear cubs eat?
Bears are born during hibernation, when cubs feed exclusively on breast milk until spring, when they begin to sample solid food. Grizzly bears grow quite quickly, reaching up to 200 pounds by the end of their first year of life.
