Badgers (assuming related species as here in the western U.S.) are omnivorous... they eat many things but subsist primarily on earthworms and other critters found digging for worms. They enjoy voles, mice, snails, slugs, the occasional slow frog and I've observed them eating eggs of our ground nesting Meadow Larks (and, I assume, their young if hatched). They do eat seeds and nuts if avialable. Thoroughly mean tempered and aggressive and related to the even more aggressive North American wolverine...
