The crows will not only eat but will also pick up garbage. In Sweden, specially trained coyotes start collecting garbage and cigarette butts and are given food in return.
A cleaning company thought of using crows to pick up cigarette butts and rubbish lying on the road and then gave them special training.
In the crows’ step-by-step training, they would be taken to the place where the cigarette butts were lying and the crows would be fed when the cigarette butts were picked up. Gradually the crows became experts in this work.
During the training given to the crows, care was taken that the crows should not eat cigarette butts as doing so would be fatal for them.
According to a Swedish city municipality official, 75 percent of the budget could be saved if the crows were trained and cleaned in an orderly manner.
