Badgers are opportunists, preying on ground-nesting birds and their eggs, mammals, reptiles, amphibians, and insects. Common dietary items are ground squirrels, pocket gophers, prairie dogs, and other smaller rodents. Occasionally they eat vegetable matter. Metabolism studies indicate that an average badger must eat about two ground squirrels or pocket gophers daily to maintain its weight. Badgers may occasionally kill small lambs and young domestic turkeys, parts of which they often will bury.
