• Where in the world: Across much of North America, from Canada and Alaska south into the United States and Mexico.

What it eats

• Diet: An omnivore that eats mostly plants but also insects and small animals, and drinks from streams and ponds.
• Favorite foods: Berries, nuts, roots, grasses, honey, insects, and fish, feasting heavily in autumn to store fat.
• How it hunts: It mostly forages, sniffing out berries and insects, tearing open logs for grubs, and scooping fish from streams.
