What do grizzly bears eat?

The diet of Grizzly Bears consists of 80 % vegetative materials but they are Omnivores. They can also have a diversified diet from eating roots to berries, insects, and mammals, to eating salmon and other fish types. 

The diet is dependent on the seasons of the year and the available foods at the time. From hibernation, Grizzly Bears cannot be limited only to vegetation, therefore, they eat marine mammals and salmon. 

Grizzly Bears can also scavenge on carcasses such as dried fish and also feed on animals that died in the winter. An exhaustive list of what  Grizzly Bears eat includes Bison, Sheep, Elk, Deer, Moose, Garbage, Nuts Tubers, Grass, Pine seeds, and Acorns.

Grizzly Bears also eat Flowers, Roots, Apples, Rodents, Carrison, Insects, and sedges.  Grizzly Bears also eat the newborn of Caribou, Moose Bison, Mountain Goats, Elk, and Sheep.

In terms of the amount of food Grizzly Bears can eat, they can consume up to 250, 000 berries in a day, especially during fall.  Grizzly Bears during summer eat moths in the Rocky Mountains at high altitude since there are plenty of Moths. They can eat for 50,000 Moths. 

When food becomes scarce  Grizzly Bears tend to migrate and find food elsewhere, therefore, conflicting with humans by invading and eating livestock. They are very dangerous to humans. 

What are  Grizzly Bears?

Grizzly Bears are brown bears mostly found in the Northern part of America. Their color varies from brown to tan.  Grizzly Bears have rounded ears and their face is dished with a hump that provides enough digging strength in their shoulder.

Grizzly Bears also have claws that are very long to dig dens or find food in rocky mountains. They have a weight of about 600 pounds for male  Grizzly Bears. Female  Grizzly Bears weigh more than male  Grizzly Bears.

Grizzly Bears communicate through smells, sounds, and movements. They make grunting, groaning, and growling sounds during mating seasons and when they search for their young ones. They also scratch their body on trees to ease irritations and also to mark territories.

How do Grizzly Bears hunt and fish?

Grizzly Bears, like polar bears, eat fish to provide them with the proteins they need. They flip and dive as a method of fishing and flipping fish from the water and using their sharp teeth to kill the fish.

Grizzly wait for fish to pass in the water then dive to catch it. Their sense of smell is great with sharp and strong teeth. All these features enable them to hunt for food. They can hunt large animals such as Caribou and Elk. 

Grizzly Bears are also opportunistic and can predate weakened, wounded, and young prey. In captivity, Grizzly Bears feed on Lard, bones, and vegetables. Zookeepers try to maintain the diet of captive Grizzly Bears similar to those in the wild.

How do  Grizzly Bears digest food?

The digestive system of Grizzly Bears is unspecialized. Their digestive duct is elongated making Grizzly Bears able to digest vegetation and meat at the same time. They lack caecum, and their digestion of plant components is poor, unlike ruminants. 

Since they poorly digest cellulose, they eat plants at their highest available nutrients and easiest to digest.  In spring,  Grizzly Bears tend to feed on pine seeds. They tend to accumulate fats in large amounts before winter for their hibernation when winter comes.

Why do Grizzly Bears Hibernate?

Grizzly Bears enter into a hibernation state as a way of conserving energy, especially in winter when there is a scarcity of food, and also to reduce their exposure to the cold during winter. 

Grizzly Bears tend to lower their heart and breathing rate. This period can go for months, especially for bears. The hibernating state for bears, unlike other animals, is light and they can easily detect danger and wake up to protect themselves. This state is called the Torpor state of light sleep.

Grizzly Bears prepare for hibernation by eating a lot of food in order to gain enough weight through the hyperphagia process where they are active in the search for food.
