Bird-Brains are Smarter than Litterbugs
A theme park in France is using birds to help clean up trash. The Puy du Fou historical park trained 6 rooks, named Boubou, Bamboo, Bill, Black, Bricole, and Baco, tp pick up rubbish. When they put it into special containers, they get a treat. They hope to teach people not to litter.
