A French theme park has trained six birds to pick up the cigarette butts and other debris that visitors leave in exchange for food.
Christophe Gaborit, the head of falconry in the Puy de Fou park in western France, raised by hand the six towers and trained them to collect garbage by offering a gift for each piece collected.
"The towers are unjustly slandered, classified as a nuisance, but these birds will perform an ecological act and restore their image," said Gaborit in the internal blog of the theme park.
The towers, which belong to the family of crow birds, will receive a nugget of food from a small box each time they deposit the garbage in a designated container.
While it & # 39; birdbrain & # 39; It has long been a pejorative term used to insult someone's intelligence, the towers are considered particularly intelligent.
Research has shown that hand-raised towers are experts in the use of tools in captivity to obtain food.
Gaborit said his birds had already tried to trick him by picking up wood chips instead of garbage.
The birds will embark on their cleaning tasks in the coming days.
