Some sets are hundreds of years old.
Badgers are nocturnal animals, foraging for food at night along hedges and wooded banks.
Their favorite foods are mice, slugs, insects, and earthworms. Although they can live to age 14, badgers often die or are killed at a younger age. Urbanization and agriculture can threaten the long-term survival of the species, since badgers adapt poorly to change once their sets are disturbed and they are forced to move. When they ventured away from their sets to hunt for food, they often had to cross roads, where they were usually killed. This badger tunnel under A73 near the town of Heumen was the first to be built in the Netherlands.
