A French theme park has begun using six trained birds belonging to the crow family to pick up litter and cigarette butts, the BBC reports . Puy du Fou is a historical theme park in Les Epesses, France, where its estimated 2 million annual visitors can learn about the French Revolution, Vikings, the Middle Ages, and other past eras, events, and people. The real and replica ancient architecture allows attendees experience simpler times of guillotines and plagues.
