DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a bird dispelling device for removing a bird that damages crops, fruits and the like, which is installed in a field, an orchard or the like.

[0002]

2. Description of the Related Art Conventionally, balloons designed with eyes of birds of prey,
Bird of prey wings, three-dimensional model of birds of prey, corpse of crow, model of cat,
Threatening by a three-dimensional object such as a scarecrow and the dead body of the bird,
Scarecrows repelled harmful birds that hurt crops in the fields and fruits in the orchard in a threatening manner due to the sudden appearance of Scarecrows.

[0003] Also, as is often seen in fields and orchards, etc., loud noises are emitted from speakers, compressed gas and explosives are exploded to intimidate, and fishing rods and mirrors are used to dispel birds by intimidation due to irregular reflection of light. I was

[0004] In addition, the harmful birds are exterminated and repelled by means of extermination by spraying chemicals and extermination by shotguns.

[0005]

However, since the harmful birds are surprisingly smart and have a high learning ability, the dolls are almost stationary, such as animal models, bird corpses, and scarecrows that imitate humans, which are natural enemies of the harmful birds. I do not look at the threats in.

[0006] In addition, sudden threats such as the sudden movement or appearance of these models, and explosive sounds such as bombers, occur in a timely manner. Because it is performed at a point far away from, it is not very effective for harmful birds who have weak vision and good sense of time, so you will notice that you need not be alert after a short time, so immediately Get used to it. Even if you make a loud noise, the problem of noise pollution will always occur.

[0007] Although one is wary of the threat of light, he is alert and cautious, but the damage to vegetables and fruits growing in the fields has not actually been reduced. Although the spraying of chemicals and the use of shotguns have the effect of reducing harmful birds, they do not extinguish them, so crops continue to be damaged.

Means of exterminating harmful birds are no longer permitted in the current era of nature conservation. In some cases, forced extermination may be performed suddenly by taking into account the amount of damage, the degree of inconvenience, and the number of birds inhabited, but this is no longer the usual method.

Therefore, the present invention does not cause damage such as loud noises or chemicals that may cause noises, does not kill or injure birds, and reliably protects crops from birds.
It is an object of the present invention to provide a harmful bird repelling device that can repel harmful birds.
