A different step taken by the management of a amusement park in France in the past period, in order to eliminate waste visitors from garbage, plastic bottles and cigarette butts.
The amusement park used six vans to get rid of visitors' waste in exchange for food.
These crows get a piece of food placed in a small container, each time they put garbage in a specific box.
Crows are highly intelligent birds, as research has proven their skill and intelligence.
The director of the falconry school at Bode de Vaux, sponsored by the crows and trained to collect garbage for food.And the third principal of the school: "Crows are oppressed and classified as a source of disturbance, but these birds do work for the environment."
