At work, a colleague told me that he was defeated by crows. One of his friends brought him a ship syrene. Placing the syrene in a box, he buried it by 1.5 meters, stretching the wire from it into the house. It turned on before leaving. When he returned for the next weekend, his neighbor began to tell him that something strange was happening in the village. The fact that crows, mice and rats fled not only from him, but also from the nearest neighbors is half the matter. The worms dispersed and the chickens in the village stopped carrying.
