JP7702130B2 - Method and device for repelling wild birds - Google Patents

Description

The present invention relates to a method and device for repelling wild birds, which disgusts them and makes them avoid flying in.

While some wild birds do not live in groups, many birds, such as pigeons, starlings, herons, cormorants, and crows, fly in flocks to nesting or feeding grounds, etc. When these birds live near human habitations, they cause various types of damage to people, including damage from their droppings and feeding.
In order to eliminate such damage caused by wild birds, many methods and devices for preventing wild birds from flying in, such as scaring off flocks of wild birds, have long been proposed.

The above-mentioned Patent Document 1 relates to a road crossing tunnel for wild animals, and discloses a technology in which a tunnel 20 is provided that crosses under a road for automobiles, etc., so that wild animals can pass through the tunnel 20 to reach the other side of the road without impeding traffic. This invention allows animals to pass through the tunnel to move to the other side of the road, but it has a different purpose than repelling wild birds.
The above-mentioned Patent Document 2 relates to a drone that uses a stuffed or modeled bird of prey such as a hawk or eagle that cries and flaps its wings, and discloses technology that uses the appearance and cries of the stuffed or modeled bird of prey such as a hawk or eagle to scare away pigeons, crows, and the like.
The above-mentioned Patent Document 3 relates to a bird repelling device, and discloses a technique for emitting a repelling sound (ultrasonic wave) within a predetermined range to repel birds.
The above-mentioned Patent Document 4 relates to a device and method for repelling birds and animals, and discloses a technique for emitting a flash of light to repel birds and animals.
The above-mentioned Patent Document 5 relates to a sheet for preventing bird damage, and discloses a technology in which a stretched wind-collecting sheet 1 is provided with pictures 3 of eyes or the like and alarm holes 4 to prevent bird damage by using pictures and sounds.

The present invention is a major departure from the wild bird repelling technologies disclosed in the above Patent Documents 2 to 5, and aims to provide a novel method and device for repelling wild birds that uses real predators, can be set once, and can maintain good effectiveness for a long period of time without any human assistance.

In order to achieve the above-mentioned object, the wild bird repelling method of the present invention has a first feature in that it uses an artificial darkened road pipe that allows predators that prey on the wild birds to be repelled or their eggs to move through it, and installs the artificial darkened road pipe so as to create a short circuit from the route along which the predators move to the elevated location where the wild birds to be repelled live, thereby enabling the predators to pass through the artificial darkened road pipe from their route of movement to the elevated location where the wild birds are located without being seen from the outside.
In addition to the first feature, the wild bird repelling method of the present invention has a second feature in that the route along which predators move is the ground including road gutters, and the elevated locations where wild birds live are elevated locations on buildings including overpasses, and an artificial dark road pipe is installed so as to short-circuit the route from the ground to the elevated location on buildings including overpasses.
In addition to the first feature, the wild bird repelling method of the present invention has a third feature in that the high places where wild birds hang out are the tops of trees, and an artificial dark road pipe is installed so as to short-circuit from the ground, including the road gutters below the trees, to the tops of the trees.
Furthermore, in addition to any one of the first to third features described above, the wild bird repelling method of the present invention has a fourth feature in that the artificial darkened tube has an inner diameter that corresponds to the predator that is a natural enemy of the wild bird to be repelled.
On the other hand, the wild bird repellent device of the present invention is equipped with an artificial darkened path pipe body that is installed to short-circuit the route along which predators move to an elevated location where wild birds live, and the artificial darkened path pipe body is constructed by connecting one or more opaque tubes in a manner that allows them to be freely inserted and removed, and the inner surface of the opaque tube is provided with anti-slip means to prevent passing predators from slipping and make it easier for them to move.This is a fifth feature of the artificial darkened path pipe body.
In addition to the fifth feature, the bird repellent device of the present invention has a sixth feature in that the anti-slip means is a plastic sponge or glass wool.
Furthermore, in addition to the fifth or sixth feature, the wild bird repellent device of the present invention has a seventh feature in that the lower end of the artificial darkened path pipe body is provided with an entrance part from the ground and an installation part for installation on the ground, and the upper end of the artificial darkened path pipe body is provided with an exit part to a high location and a hook part.
In addition to the seventh feature, the wild bird repellent device of the present invention has an eighth feature in that the inlet and outlet portions of the artificial darkened path tube are curved so that they open at a gentle angle less than a right angle to the ground and to a high place, respectively.

According to the method for repelling wild birds described in claim 1, an artificial dark path pipe is prepared, and an operator installs this artificial dark path pipe so as to short-circuit the predator's route to the high place where the repelled wild bird lives. The predator enters the artificial dark path pipe from the route where it moves at night, even by chance. Then, by moving through the artificial dark path pipe without being detected by people or wild birds, the predator can sneak into the high place where the wild bird lives in a very short time. Therefore, it is easy for the predator to capture the wild bird as prey. On the other hand, for the wild bird, the predator suddenly invades through the artificial dark path pipe that cannot be seen from the outside, so it is difficult to escape, the damage is great, and the fear is great. Therefore, once a wild bird has been victimized, it will not approach a dangerous place where it is not possible to adequately watch for the intrusion of a predator.
According to the method for repelling wild birds in claim 1, it is only necessary to install the artificial dark path pipe at a high place where wild birds live, away from the predator's movement route, and there is no need for workers to scare them away, and no power source such as batteries is required. In particular, since the predators that invade are real natural enemies of wild birds, they do not get used to them, and the repelling effect can be maintained for a long time.
Furthermore, for predators, on the way from their own route to higher places where wild birds are, they can move through the artificial dark passage pipe without being found by wild birds or humans, etc. Therefore, predators can carry out capture actions while ensuring their own safety, and since they frequently attempt to invade, the repellent effect on wild birds is high and lasts for a long time.

According to the method for repelling wild birds described in claim 2, in addition to the effects of the configuration described in claim 1, the route along which predators move is the ground, including road gutters, and the high places where wild birds live are the high places of buildings, including overpasses, and the artificial dark road pipe is short-circuited and installed from the ground to the high places of buildings, including overpasses. Therefore, predators can move quickly and unseen from the ground, including safe road gutters, where they move on a daily basis, to the high places of buildings, including overpasses, where wild birds tend to gather, and suddenly attack wild birds. Therefore, it is possible to cause great fear even in wild birds that gather at the high places of buildings such as overpasses, which have had little repelling effect until now, and once an attack has occurred, the installation of the artificial dark road pipe itself has a great repelling effect.

According to the method for repelling wild birds described in claim 3, in addition to the effects of the configuration described in claim 1, the high places where wild birds live are the tops of trees, and the artificial darkened pipes are installed in a short circuit from the ground, including the drains under the trees, to the tops of the trees. This allows predators to quickly invade the trees, where wild birds tend to gather, through the artificial darkened pipes without being seen, and attack the wild birds. Therefore, the fear of the wild birds that are suddenly attacked remains strong at least while the artificial darkened pipes are installed, and a long-term repelling effect can be expected against wild birds that nest in trees.

According to the method for repelling wild birds described in claim 4, in addition to the effects of the configuration described in any one of claims 1 to 3, the artificial darkened pipe has an inner diameter that corresponds to the predator that is the natural enemy of the wild birds to be repelled. Therefore, by using an artificial darkened pipe that is suitable for the natural enemies of the birds that gather, the predator can more easily and quickly enter the high places where the wild birds are, further enhancing the repelling effect.

According to the wild bird repellent device described in claim 5, an artificial darkened path pipe is provided which is installed to short-circuit the route along which predators move to an elevated location where wild birds live, and the artificial darkened path pipe is constructed by connecting one or more opaque tubes in a manner that allows them to be freely inserted and removed, and the inner surface of the opaque tube is provided with anti-slip means to prevent passing predators from slipping and make it easier for them to move.
By installing the artificial darkened pipe, predators can quickly invade from their own routes to the high places where wild birds live through the artificial darkened pipe without being seen by anyone and suddenly attack. Therefore, since real predators invade suddenly, the effect of fearing and repelling wild birds by installing the artificial darkened pipe is large and long-lasting.
The artificial dark path tube is constructed by connecting one or more opaque tubes in a freely insertable and removable manner, so that it can be adjusted according to the required installation height.
In particular, since the artificial dark pipe body is composed of opaque pipes, the inside cannot be seen from the outside, and for predators passing through it, they can quickly move to the desired high place and achieve their goal without being found by the wild birds they are trying to catch, and therefore cannot escape, and also without being found by humans.
Furthermore, the artificial dark passage pipe is provided on its inner surface with anti-slip means for preventing passing predators from slipping and making it easier for them to move, so that even if the predators are moving up and down steep slopes, they can move quickly and reliably without slipping, capture prey, and carry the captured prey.

According to the wild bird repellent device described in claim 6, in addition to the advantageous effects of the configuration described in claim 5, the anti-slip means is a plastic sponge or glass wool, so it can be reliably attached by gluing or the like whether the opaque tube is made of plastic or metal. Moreover, the surfaces of plastic sponge and glass wool are usually finely roughened, so that it is possible to make it sufficiently difficult for predators to pass through without slipping.

According to the wild bird repellent device described in claim 7, in addition to the advantageous effects of the configuration described in claim 5 or 6, the lower end of the artificial darkened path pipe is provided with an entrance portion from the ground and an installation portion on the ground, and the upper end of the artificial darkened path pipe is provided with an exit portion to a high location and a hook portion. Therefore, by installing the artificial darkened path pipe on the ground using the installation portion at the lower end and hooking it to the desired high location using the hook portion at the upper end, the artificial darkened path pipe can be stably installed from the ground to the desired high location.
In addition, predators on the ground can be easily received through an entrance provided at the lower end of the artificial darkened passage pipe, and predators can be sent to a higher location through an exit provided at the upper end of the artificial darkened passage pipe.

According to the wild bird repelling device described in claim 8, in addition to the effect of the configuration described in claim 7, the entrance and exit of the artificial dark path pipe are bent so that they open at a gentle angle less than a right angle to the ground and the high place, respectively. Therefore, it is easy for predators to enter and exit from the ground through the entrance that opens at a gentle angle, and easy for them to enter and exit the high place through the exit that opens at a gentle angle. And they can easily carry the captured prey through the artificial dark path pipe.

FIG. 1 is a perspective view of the vicinity of the upper end of a wild bird repellent device according to an embodiment of the present invention. FIG. FIG. 2 is a diagram illustrating a method for repelling wild birds according to an embodiment of the present invention. 11A to 11C are diagrams illustrating a method for repelling wild birds according to another embodiment of the present invention.

The following describes the bird repelling method and device according to an embodiment of the present invention with reference to the drawings to aid in understanding the invention. However, the following description does not limit the invention described in the claims.

First, referring to Figures 1 to 4, a wild bird repelling device according to an embodiment of the present invention includes an artificial darkened path pipe 10. This artificial darkened path pipe 10 can be installed so as to short-circuit the route from the route where predators move to the high places where wild birds live, allowing it to function as a wild bird repelling device.

The artificial darkened pipe 10 is a pipe through which predators can pass. This artificial darkened pipe 10 is constructed using an opaque pipe 11. The inner surface of the opaque pipe 11 is provided with anti-slip means 12 to prevent predators from slipping when passing through and to make it easier for them to move.

The artificial darkened pipe 10 is constructed of an opaque pipe 11 in order to prevent wild birds and people from seeing predators passing through the artificial darkened pipe 10 from outside the artificial darkened pipe 10.
The inner diameter of the artificial darkened pipe 10 is set to a diameter that allows the predators expected to pass through to move smoothly with the anti-slip means 12 applied to its inner surface. However, a larger diameter is not necessarily better, and the artificial darkened pipe 10 should be selected taking into consideration the portability, ease of installation, strength, etc. of the artificial darkened pipe 10.
The opaque tube 11 can be constructed as a straight artificial dark path tube 10 by connecting one or more straight opaque tubes 11a alone. However, if necessary, it can also be constructed by combining a curved opaque tube 11b with the straight opaque tube 11a.
In this embodiment, the artificial dark path tube 10 is formed by connecting two straight opaque tubes 11a and two curved opaque tubes 11b.
The curved opaque tube 11b can be used mainly at the upper end and the lower end of the artificial dark path tube 10. The curved opaque tube 11b can be, for example, a short tube for connection with an angle, called an elbow.
The opaque tubes 11 can be freely connected and disconnected, so that the height (length) of the artificial darkened pipe body 10 can be adjusted according to the height from the ground to the high place.
The opaque tube 11 may be an opaque plastic tube such as polyvinyl chloride, or may be a metal tube. A waterproof paper tube may also be used, which is light and suitable for short-term use.

The anti-slip means 12 is applied to the inner surface of the opaque tube 11 to prevent predators moving through the artificial darkened tube 10 from slipping and to facilitate their movement. As the anti-slip means 12, a sponge or glass wool made of plastic or the like can be preferably used. The surface of the sponge or glass wool can provide a sufficiently rough surface, so that the predators can be sufficiently prevented from slipping. However, a fine-meshed sponge or glass wool is preferred so that the feet of the predators do not get excessively caught in the sponge or glass wool, making it difficult for them to move.
Of course, the anti-slip means 12 is not limited to the sponge or glass wool, but may be a roughened surface of the inner surface of the opaque tube 11 itself.

An entrance 13 from the ground can be provided at the lower end of the artificial darkened pipe 10. Also, an exit 14 to a high place can be provided at the upper end of the artificial darkened pipe 10.
The entrance 13 can be designed so that a predator can smoothly enter the artificial darkened pipe 10 from the ground (or smoothly exit from the artificial darkened pipe 10 to the ground). For example, the entrance 13 can be designed to open at a gentle angle less than a right angle to the ground. This can be achieved by connecting a short curved opaque pipe 11b called an elbow to the lower end of the straight opaque pipe 11a.
The exit section 14 can be designed so that a predator can smoothly exit from the artificial darkened pipe body 10 to a high place (or smoothly enter from a high place into the artificial darkened pipe body 10). As in the case of the entrance section 13, this can be achieved by connecting a short curved opaque pipe 11b called an elbow to the upper end of a straight opaque pipe 11a located near the upper end of the artificial darkened pipe body 10.

A ground installation part 15 can be provided at the lower end of the artificial dark path pipe 10. A hook part 16 for hanging at a high place can be provided at the upper end of the artificial dark path pipe 10.
The installation section 15 can be composed of a base 15a that is fixed by fitting, for example, to the opaque tube 11 (mainly the curved opaque tube 11b) near the lower end of the artificial dark path tube 10, and a pair of legs 15b, 15b provided on both sides of the base 15a. The pair of legs 15b of the installation section 15 are grounded on the ground, so that the artificial dark path tube 10 is stably installed on the ground.
On the other hand, the hook portion 16 can be composed of a base portion 16a that is fixed by fitting the vicinity of the upper end portion of the artificial dark path pipe body 10 to the opaque pipe 11 (mainly the curved opaque pipe 11b) and a pair of claw portions 16b, 16b that extend from the base portion 16a. The pair of claw portions 16b of the hook portion 16 are hooked on a high place, so that the artificial dark path pipe body 10 can be stably installed at a high place.

5 and 6, the bird repelling device and the bird repelling method will be further described.
5 shows an artificial dark road pipe 10 installed in a short circuit from the ground G of the route along which the predator E moves to a high place H on a building, including an elevated road, where the wild bird B lives. Here, the ground G includes the ground surface made of soil and other artificial materials, and further includes the roadside gutters where the predator E can easily move as a living area.
In FIG. 5, the artificial dark path pipe 10 is shown in cross section.
The artificial dark path pipe 10 uses one or more straight opaque pipes 11a connected to both ends of short curved opaque pipes 11b to form an inlet 13 and an outlet 14. Although the installation part 15 and the hook part 16 are not used, they can be used together.
On the other hand, pigeons, starlings, herons, cormorants, crows, and other birds correspond to the wild birds B. Also, weasels, cats, raccoons, palm civets, raccoon dogs, martens, and other birds correspond to the predators E.

Now, if the elevated area is the elevated place H, the wild birds B that gather there are pigeons, and the predator E that is convenient for pigeons to avoid is the weasel, then an artificial darkened pipe 10 with an inner diameter large enough for the weasel to move around easily inside it is used. This artificial darkened pipe 10 is installed so that it is short-circuited from the ground G to the elevated place H on the elevated area.
If it is set up as described above, at night several hours or days later, or during the activity period of the predator E, not only the weasel but also smaller predators E and other predators E that can pass through the artificial dark road pipe body 10 will have the opportunity to enter the artificial dark road pipe body 10 from the ground G of the activity route, and will be able to move smoothly without being detected from the outside due to the opaque pipe 11, and will be able to run up to the high place H in a short time and invade without slipping on the slope inside the pipe due to the non-slip means 12.
On the other hand, the pigeons B at the high place H cannot find the weasel E invading through the artificial dark road pipe body 10, and so they are captured, have their eggs stolen, or are injured by the weasel E that suddenly invades right in front of them, causing them great damage and fear.
Therefore, pigeon B, which has been attacked once, and the pigeons B around it, become very frightened and will no longer approach the high place H.
Of course, even if Weasel E does not come afterwards, the fear of not knowing when Weasel E will come is great for Pigeon B, having been attacked once, and the strong repellent effect will continue for a long time.

FIG. 6 shows a case where the artificial darkened pipe 10 is used to repel wild birds B that gather on trees.
Now, assuming that the top of a tree is an elevated place H, the wild birds B that gather there are starlings, and the predator E that is convenient for repelling starlings is a cat, an artificial darkened passage pipe 10 having an inner diameter large enough for a cat to suitably move through it is installed from the ground G to the elevated place H on the tree.
The artificial dark path tube 10 is made by connecting one or more straight opaque tubes 11a to both ends of which are short curved opaque tubes 11b, forming a gentle inlet section 13 and an outlet section 14. The artificial dark path tube 10 is provided with an installation section 15 at the lower end and a hook section 16 at the upper end.
The artificial dark path pipe 10 is firmly installed on the ground G by the installation part 15 at its lower end, and is stabilized by firmly hooking the hook part 16 at its upper end to a high place H on a tree. At this time, the entrance part 13 and the exit part 14 are arranged gently at a low angle or parallel to the ground G and the high place H, respectively, which is less than a right angle.

When the artificial dark road pipe body 10 is set up as described above, a cat E or other predator E that can pass through the artificial dark road pipe body 10 can quickly run up the artificial dark road pipe body 10 from the ground B of the route of movement without being detected, and enter a high place H on a tree where starlings B and other wild birds B gather.
Starlings B and other wild birds B gathering on the tree are suddenly attacked by a real predator E, which is their natural enemy, and are left feeling a great deal of fear, so they never go near that tree again.

The present invention can be used industrially as a method and device for repelling wild birds.
