Grizzly bears are omnivores, meaning they eat both plants and animals. Their diet varies depending on the season and what is available in their habitat. Here are some of the foods that grizzly bears eat:

Plants:

• Insects
• Grass
• Broad-leaved herbs
• Tubers
• Sedges
• Berries
• Roots
• Fungi
• Green herbaceous plants
• Shoots, leaves, and stems of plants
• Fruits
• Nuts
• Ferns

Animals:

• Fish, especially salmon
• Rodents, such as ground squirrels
• Carrion, including winter-killed and wolf-killed ungulates
• Hoofed animals, such as moose, elk, caribou, and deer
• Invertebrates, such as army cutworm moths and ants

Grizzly bears are also known to scavenge for food from plants or household garbage depending on what is convenient. They can gain up to six pounds in a day as they are big eaters.
