A French park has found a new way to maintain the grounds: free labor from crows. Rooks, a member of the crow family considered to be “particularly intelligent” are being trained to pick up cigarette butts and trash and will start working at the historical theme park in France.
The six rooks are encouraged to spruce up the park with the use of a small box that delivers a nugget of bird food every time the bird drops a small piece of garbage.
“The goal is not just to clear up, because the visitors are generally careful to keep things clean,” explains Nicholas de Villiers, with the park, but also to show that “nature itself can teach us to take care of the environment.”
