Plant Matter:
* Grasses, sedges, and other herbaceous plants: This makes up a large portion of their diet, especially in the spring and summer.
* Berries: Berries like blueberries, raspberries, and huckleberries are a favorite food source and provide a lot of energy.
* Roots and bulbs: They dig for roots and bulbs, especially in the fall.
* Nuts and seeds: They eat nuts like acorns and pine nuts, and seeds from plants like dandelions and clover.
Animal Matter:
* Fish: Salmon, trout, and other fish are a key food source in areas where they are available, especially during the summer months.
* Mammals: They will prey on elk, deer, moose, caribou, and other large mammals, as well as smaller animals like squirrels, marmots, and even rodents.
* Carrion: They are scavengers and will eat carcasses of animals they didn't kill themselves.
* Insects: They eat ants, beetles, and other insects, especially in the spring and fall.
Other:
* Honey: They will raid beehives to get honey.
* Bird eggs: They will eat bird eggs, particularly those found in nests on the ground.
* Garbage: Unfortunately, grizzly bears can become accustomed to human food sources like garbage, which can lead to conflict with humans.
Grizzly bears are very adaptable and their diet changes depending on the season and availability of food. They can survive on a diet of mostly plants in the summer, but they need to eat a lot of fat and protein in the fall to build up reserves for hibernation.
