1 Corvids （鴉類） are known to be remarkably intelligentanimals. These birds are good at usingtools， can plan ahead， solve puzzles and evenhold grudges （怨恨）. Some corvids＇ brains havereally high neuronal densities and a brain regioncalled the nidopallium caudolaterale， or NCLwhich is believed to act like our prefrontalcortex—the problem?solving part of the human brain.

2 Rooks are members of the crow family. Six rooks—Boubou， Bamboo， Bill， Black， Bricoleand Baco—were trained to pick up litter after people. They are employees of thePuy du Fou park， a history?themed park located in Les Epesses， a four?hour drive fromParis， France.

3 The idea to train rooks originally came from the parks falconry （鷹獵） show， duringwhich trained corvids would pick up roses and bring them to a“ princess” in a castle.This got Christophe Gaborit， project manager at the park， thinking whether he＇d be ableto teach rooks to perform a similar task—like picking up cigarette butts and othersmall pieces of trash and putting them in a box.

4 When the birds placed a piece of trash in a box， their trainer would pull a board to reveala delicious snack for them. At last， the rooks started to associate tidying up withfood， and were happy to pick up small pieces of trash in order to get rewards. The birdswould sometimes try to trick Gaborit and instead of disposing of garbage， would insteaddrop pieces of wood into the box.

5 “We don＇t want to make them machines，” the president of the Puy du Fou park， Nicolasde Villiers， said“. They don＇t play the game if they work too much.”

6 The birds“ work” under supervision of a falconer， who makes sure that people dontthrow garbage around just to watch the rooks pick it up. Instead， Boubou， Bamboo， Bill，Black， Bricole and Baco are there to educate the park visitors about littering.“ Natureitself can teach us to take care of the environment，” Villiers said.
