[Problems to be solved by the device]

 Sakayamako was used in the past to prevent bird damage that damages agricultural crops, and currently, glittering tape and PET bottles are put around the fields, but none of these have a decisive effect.

[0002]

[Means for Solving the Problems]

 Birds flying in the sky have a habit of reacting sensitively to moving things on the ground, and if the windmill is spinning, they will notice immediately. In addition, the crow is the most feared of all the birds, and I got the hint that if the crow stays on a power pole or a tree branch, the other birds will disappear for the most part. Birds are prevented by combining these.

[0003]

[Effect of the invention]

 This bird damage preventer was attached to the tip of a stick of about 3 m, and it was placed in a field and tested for 6 months, and the following was found. (1) Birds other than crows do not approach within a 50m radius. (2) Birds have begun to fly around the sky more than 50m away without crossing directly above the device. (3) Crows are less likely to descend within a radius of 50m.
