Description

Technical Field

[0001] The present invention relates to a method and device for repelling wild birds so that they dislike and avoid flying in.

Background Art

[0002] Among wild birds, there are some birds that act alone, while there are also many birds such as pigeons, crows, herons, cormorants, and crows that flock to places such as nesting sites and feeding sites and live in groups. When these birds live near human living places, they will cause various damages to humans, including fecal damage and food damage. In order to eliminate the damages caused by such wild birds, technologies related to methods and devices for preventing wild birds from flying in, such as threatening and driving away flocks of wild birds, have been provided in large numbers since ancient times.

Summary of the Invention

Problems to be Solved by the Invention

[0004] Patent Document 1 relates to a wildlife road-crossing tunnel. By providing a tunnel 20 that crosses under a road for automobiles or the like, a technique is disclosed that enables wild animals to pass through the tunnel 20 to the other side of the road without disturbing traffic. This invention enables animals to move to the other side of the road through the tunnel, but it is for a different purpose than repelling wild birds. Patent Document 2 relates to a drone using a stuffed or modeled bird of prey such as an eagle or a vulture that makes a crying sound and flaps its wings. A technique is disclosed that uses the appearance and crying sound of a stuffed or modeled bird of prey such as an eagle or a vulture to drive away pigeons, crows, etc. Patent Document 3 relates to a bird repelling device. A technique is disclosed that emits a repelling sound (ultrasonic wave) within a predetermined range to drive away birds. Patent Document 4 relates to a bird and animal repelling device and method. A technique is disclosed that generates a flash to drive away birds and animals. Patent Document 5 relates to a bird damage prevention sheet. A technique is disclosed that provides a picture 3 such as an eyeball and a warning hole 4 on a stretched air collecting sheet 1 to prevent bird damage by means of the picture and sound.

[0005] The present invention significantly changes the concept from the wild bird repelling techniques disclosed in Patent Documents 2 to 5 above. The object is to provide a novel wild bird repelling method and device that utilize real predator animals, and once set up, can continue to have good effects over a long period without the need for human intervention.

Means for Solving the Problems

[0006] To achieve the above object, the wild bird repelling method of the present invention uses an artificial underground pipe body that allows a predator animal that preys on the wild birds to be repelled or their eggs to move through it, and installs the artificial underground pipe body so as to short-circuit from the action path where the predator animal acts to the high place where the wild birds to be repelled nest. Thus, the first feature is that it enables the predator animal to enter from the action path through the artificial underground pipe body to the high place where the wild birds are located without being visible from the outside. In addition to the above first feature, the method for repelling wild birds according to the present invention is characterized in that the action path where the predatory animal moves is the ground including the roadside ditch, the high place where the wild bird inhabits is the high place of the building including the elevated structure, and the second feature is that an artificial underground conduit is installed in a short-circuit manner from the ground to the high place of the building including the elevated structure. In addition to the above first feature, the method for repelling wild birds according to the present invention is characterized in that the high place where the wild bird inhabits is on the tree, and the third feature is that an artificial underground conduit is installed in a short-circuit manner from the ground including the roadside ditch under the tree to the top of the tree. In addition to any one of the above first to third features, the method for repelling wild birds according to the present invention is characterized in that the artificial underground conduit uses an inner diameter corresponding to the predatory animal that is the natural enemy of the wild bird to be repelled as the fourth feature. On the other hand, the device for repelling wild birds according to the present invention includes an artificial underground conduit installed in a short-circuit manner from the action path where the predatory animal moves to the high place where the wild bird inhabits. The artificial underground conduit is configured by detachably connecting one or a plurality of opaque tubes, and the inner surface of the opaque tube is provided with anti-slip means for preventing the passing predatory animal from slipping and facilitating movement, which is the fifth feature. In addition to the above fifth feature, the device for repelling wild birds according to the present invention is characterized in that the anti-slip means is a sponge or glass wool made of plastics as the sixth feature. In addition to the above fifth or sixth feature, the device for repelling wild birds according to the present invention is characterized in that at the lower end of the artificial underground conduit, an entrance part from the ground and an installation part on the ground are provided, and at the upper end of the artificial underground conduit, an exit part to the high place and a hanging part are provided as the seventh feature. In addition to the above seventh feature, the device for repelling wild birds according to the present invention is characterized in that the entrance part and the exit part of the artificial underground conduit are bent so as to open at a gentle angle less than a right angle with respect to the ground and the high place respectively as the eighth feature.

Effects of the Invention

[0007] According to the method for repelling wild birds described in claim 1, an artificial underground pipe is prepared, and an operator installs the artificial underground pipe so as to short-circuit from the movement path of a predatory animal to a high place where a wild bird to be repelled nests. The predatory animal accidentally enters the artificial underground pipe from its movement path at night or the like. By advancing through the artificial underground pipe without being discovered by humans or wild birds, the predatory animal can sneak into the high place where the wild bird nests in a very short time. Therefore, it is easy for the predatory animal to capture the wild bird as prey. On the other hand, for wild birds, since the predatory animal suddenly intrudes through the artificial underground pipe where it cannot be seen from the outside, it is difficult to escape, the damage is large, and the fear is also great. Therefore, wild birds that have been damaged once will not approach dangerous places where they cannot fully keep watch for the intrusion of predatory animals. Moreover, according to the method for repelling wild birds of claim 1, it is only necessary to install the artificial underground pipe from the movement path of the predatory animal to the high place where the wild bird nests. There is no need for an operator or the like to drive them away themselves, and no power source such as a battery is required at all. In particular, for wild birds, the predatory animals that intrude are real natural enemy animals, so they are not accustomed to it, and the repelling effect can be maintained for a long time. Furthermore, for the predatory animal, on the way from its movement path to the high place where the wild bird is, it can move through the artificial underground pipe without being discovered not only by the wild bird but also by humans or the like. Therefore, the predatory animal can carry out the capture action while ensuring its own safety. Since it frequently tries to intrude, the repelling effect on wild birds is high and lasts for a long time.

[0008] 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 paths where predatory animals move are the ground including roadside ditches, the high places where wild birds inhabit are the high places of buildings including elevated structures, and an artificial underground conduit is installed so as to short-circuit from the ground including roadside ditches to the high places of buildings including elevated structures. Therefore, a predatory animal can move quickly and invisibly from the ground including the safe roadside ditches where it usually moves to the high places of buildings including elevated structures where wild birds tend to gather, and can suddenly attack the wild birds. Therefore, it is possible to create a state that gives great fear even to wild birds that gather in high places of buildings such as elevated structures where the repelling effect has been small until now. Once attacked, the mere presence of the installed artificial underground conduit itself has a great repelling effect.

[0009] 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 inhabit are the tops of trees, and an artificial underground conduit is installed so as to short-circuit from the ground including the roadside ditches under the trees to the tops of the trees. Therefore, it becomes possible for a predatory animal to quickly and invisibly invade from the ground including the roadside ditches through the artificial underground conduit to the tops of the trees where wild birds tend to gather and attack the wild birds. Therefore, the fear for the suddenly attacked wild birds remains large, at least while the artificial underground conduit is installed, and a long-term repelling effect can be expected for the wild birds nesting in the trees.

[0010] 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 underground conduit is of an inner diameter corresponding to a predatory animal that is a natural enemy of the wild birds to be repelled. Therefore, by using an artificial underground conduit suitable for the natural enemy of the gathering birds, the predatory animal that is the natural enemy can more easily and quickly invade the high places where the wild birds are, and the repelling effect can be further enhanced.

[0011] According to the wild bird repellent device described in claim 5, it is provided with an artificial dark path pipe body that is short-circuited from the action path of the predatory animal to the high place where the wild bird lives. The artificial dark path pipe body is composed of connecting one to a plurality of opaque pipes detachably, and on the inner surface of the opaque pipe, anti-slip means is provided to prevent the passing predatory animal from slipping and make it easier to move. By installing the artificial dark path pipe body, the predatory animal can penetrate through the artificial dark path pipe body from its own action path to the high place where the wild bird lives, without being discovered by anyone, and quickly invade and make a surprise attack. Therefore, due to the sudden intrusion of the real predatory animal, the effect of fear and repellence on the wild bird by installing the artificial dark path pipe body is great and long-lasting. Since the artificial dark path pipe body is composed of connecting one to a plurality of opaque pipes detachably, it can be adjusted according to the required installation height. In particular, since the artificial dark path pipe body is composed of opaque pipes, the inside cannot be seen from the outside. For the predatory animal passing through it, it cannot be discovered by the wild bird targeted for capture, so it cannot escape, and it cannot be discovered by humans either. It can quickly move to the target high place and achieve the goal. Furthermore, since the artificial dark path pipe body is provided with anti-slip means on its inner surface to prevent the passing predatory animal from slipping and make it easier to move, even for the predatory animal in a sudden up-and-down movement, it can move back and forth quickly and surely without slipping, capture the prey, and carry the captured prey.

[0012] According to the wild bird repellent device described in claim 6, in addition to the action effects of the configuration described in claim 5 above, since the anti-slip means is a sponge or glass wool made of plastics, it can be reliably adhered etc. whether the opaque pipe is made of plastic or metal. Moreover, since the sponge and glass wool made of plastics are usually in a state where the surface is finely roughened, it can be made into a state where it is sufficiently difficult for the predatory animal to slip when moving back and forth.

[0013] According to the wild bird repellent device described in claim 7, in addition to the operational effects of the configuration described in claim 5 or 6 above, at the lower end of the artificial culvert tube, an entrance from the ground and an installation part on the ground are provided, and at the upper end of the artificial culvert tube, an exit to a high place and a hanging part are provided. Therefore, it is installed on the ground at the installation part provided at the lower end of the artificial culvert tube, and by hanging it at the desired high place with the hanging part at the upper end, the artificial culvert tube can be stably installed from the ground to the target high place. In addition, it can easily accept predatory animals on the ground from the entrance provided at the lower end of the artificial culvert tube, and can send predatory animals to a high place from the exit at the upper end of the artificial culvert tube.

[0014] According to the wild bird repellent device described in claim 8, in addition to the operational effects of the configuration described in claim 7 above, the entrance and exit of the artificial culvert tube are bent so as to open at a gentle angle less than a right angle with respect to the ground and the high place, respectively. Therefore, for predatory animals, it is easy to enter and exit from the ground through the entrance that opens at a gentle angle, and it is also easy to enter and exit to a high place through the exit that opens at a gentle angle. And the captured prey can be easily carried through the artificial culvert tube.

Embodiments for Carrying Out the Invention

[0016] Hereinafter, with reference to each drawing, a method and apparatus for wild bird repulsion according to an embodiment of the present invention will be described to facilitate understanding of the present invention. However, the following description does not limit the present invention described in the claims.

[0017] First, referring to FIGS. 1 to 4, a wild bird repulsion apparatus according to an embodiment of the present invention includes an artificial dark path tube 10. By installing this artificial dark path tube 10 so as to short-circuit from the action path where a predatory animal moves to a high place where a wild bird lives, it can function as a wild bird repulsion apparatus.

[0018] The artificial dark path tube 10 is a tube that allows a predatory animal to come and go inside. This artificial dark path tube 10 is configured using an opaque tube 11. On the inner surface of the opaque tube 11, anti-slip means 12 is provided to prevent the predatory animal from slipping when moving back and forth and make it easier to move.

[0019] The reason for configuring the artificial dark path tube 10 with the opaque tube 11 is to prevent wild birds and humans from seeing the predatory animals moving back and forth inside the artificial dark path tube 10 from outside the artificial dark path tube 10. The inner diameter of the artificial dark path tube 10 is set to a diameter that allows the predatory animal expected to come and go to move smoothly with the anti-slip means 12 provided on its inner surface. However, it is not just a matter of being large, and it will be selected in consideration of the portability, ease of installation, strength, etc. of the artificial dark path tube 10. The opaque tube 11 can be configured as a straight tubular artificial dark path tube 10 by using only a straight tubular opaque tube 11a and connecting one or more of them. However, if necessary, a curved tubular opaque tube 11b can also be combined with the straight tubular opaque tube 11a for configuration. In this embodiment, two straight tubular opaque tubes 11a and two curved tubular opaque tubes 11b are connected to form the artificial dark path tube 10. The curved tubular opaque tube 11b can mainly be used for the upper and lower ends of the artificial dark path tube 10. The curved tubular opaque tube 11b can use, for example, a short tube for connection with an angle called an elbow. The connection of each of the opaque pipes 11 is made detachable so that the height (length) of the artificial buried conduit 10 can be adjusted according to the height from the ground to a high place. As the opaque pipe 11, an opaque plastic pipe such as vinyl chloride can be used, but a metal pipe may also be used. Also, a paper pipe with waterproof treatment is light and possible for a short term.

[0020] The anti-slip means 12 is provided on the inner surface of the opaque pipe 11 in order to prevent a predatory animal moving back and forth inside the artificial buried conduit 10 from slipping and make it easier to move. As this anti-slip means 12, a sponge or glass wool made of plastic or the like can be preferably used. Since the surfaces of the sponge and glass wool can provide a sufficient rough surface, it is possible to sufficiently prevent a predatory animal from slipping. However, in order to prevent the feet of the predatory animal from being excessively caught by the sponge or glass wool and making it difficult to move, a sponge or glass wool with fine pores is preferable. Of course, the anti-slip means 12 is not limited to the sponge or glass wool, and it may be a rough surface treatment for the inner surface of the opaque pipe 11 itself.

[0021] An entrance portion 13 from the ground can be provided at the lower end of the artificial buried conduit 10. Also, an exit portion 14 to a high place can be provided at the upper end of the artificial buried conduit 10. The entrance portion 13 can be devised so that a predatory animal can smoothly enter the artificial buried conduit 10 from the ground (or can smoothly exit from the artificial buried conduit 10 to the ground). For example, the entrance portion 13 can be configured to open at a gentle angle less than a right angle with respect to the ground. This can be obtained by connecting a short curved tubular opaque pipe 11b called an elbow to the lower end of a straight tubular opaque pipe 11a. The exit part 14 can be designed so that the predatory animal can smoothly exit from the inside of the artificial culvert tube 10 to a high place (or smoothly enter from a high place into the artificial culvert tube 10). Similar to the case of the entrance part 13, this can be achieved, for example, by connecting a short curved tubular opaque tube 11b, called an elbow, to the upper end of a straight tubular opaque tube 11a located near the upper end of the artificial culvert tube 10.

[0022] An installation part 15 for the ground can be provided at the lower end of the artificial culvert tube 10. Also, a hanging part 16 for a high place can be provided at the upper end of the artificial culvert tube 10. The installation part 15 can be composed of, for example, a base part 15a fixed by fitting it to an opaque tube 11 (mainly a curved tubular opaque tube 11b) near the lower end of the artificial culvert tube 10, and a pair of leg parts 15b, 15b provided on both sides of the base part 15a. When the pair of leg parts 15b of the installation part 15 contact the ground, the installation of the artificial culvert tube 10 on the ground becomes stable. On the other hand, the hanging part 16 can be composed of, for example, a base part 16a fixed by fitting the vicinity of the upper end of the artificial culvert tube 10 to an opaque tube 11 (mainly a curved tubular opaque tube 11b), and a pair of claw parts 16b, 16b extending from the base part 16a. When the pair of claw parts 16b of the hanging part 16 catch on a high place, the installation of the artificial culvert tube 10 at a high place becomes stable.

[0023] Referring also to FIGS. 5 and 6, further explanation of the wild bird repellent device and the wild bird repellent method will be advanced. FIG. 5 shows a state in which the artificial culvert tube 10 is short-circuited and installed from the ground G of the action path where the predatory animal E moves to a high place H above a building including an elevated structure where the wild bird B nests, using the artificial culvert tube 10. Here, the ground G includes the ground surface composed of soil and other artificial objects, and further includes the roadside ditch of the road where the predatory animal E easily moves as its living area in the ground G. In addition, in FIG. 5, the artificial culvert tube 10 is shown in cross-section. The artificial dark path pipe body 10 uses a structure where one or more straight tubular opaque pipes 11a are connected to curved tubular opaque pipes 11b made of short pipes at both ends thereof to form an inlet portion 13 and an outlet portion 14. Also, although the installation portion 15 and the hooking portion 16 are not used, they can be used together. On the other hand, as the above wild bird B, pigeons, cuckoos, herons, cormorants, crows, and other birds are applicable. Also, as the predatory animal E, weasels, cats, raccoons, martens, raccoon dogs, badgers, and others are applicable.

[0024] Now, taking the upper part of the elevated structure as the high place H, the wild bird B gathering there as pigeons, and the predatory animal E convenient for repelling pigeons as weasels, an artificial dark path pipe body 10 with an inner diameter of a size that allows a weasel to move through it suitably will be used. This artificial dark path pipe body 10 is installed so as to short-circuit from the ground G to the high place H on the elevated structure. If installed as described above, at night after several hours or several days, or during the activity time zone of the predatory animal E, not only weasels, but also smaller predatory animals E or other predatory animals E that can pass through the artificial dark path pipe body 10 will get the opportunity to enter from the ground G of the movement path into the artificial dark path pipe body 10. Without being discovered from the outside by the opaque pipe 11, and without slipping on the slope inside the pipe by the anti-slip means 12, they can move smoothly, rush up to the high place H in a short time, and complete the intrusion. On the other hand, the pigeons B at the high place H cannot discover the weasels E that intrude through the artificial dark path pipe body 10. So, they will be captured by the suddenly intruding weasels E in front of their eyes, have their eggs taken, or be injured, suffering great damage and fear. Therefore, the fear of the pigeons B that have been attacked once and the pigeons B around them is great, and they will not approach the high place H hereafter. Of course, after that, even if the weasels E do not come, for the pigeons B that have been attacked once, the fear of when the weasels E will come is great, and a strong repelling effect will continue for a long time.

[0025] Figure 6 shows a case where the artificial dark path pipe body 10 is used to repel wild birds B from gathering on a tree. Now, taking the high place H on the tree as the high place, the wild birds B gathering there as the long-tailed tits, and the predatory animal E convenient for repelling the long-tailed tits as the cat, an artificial dark path tube body 10 with an inner diameter large enough for the cat to move through it comfortably is used and installed from the ground G to the high place H on the tree. As the artificial dark path tube body 10, one or more straight tubular opaque tubes 11a are each connected to curved tubular opaque tubes 11b of short tubes at both ends thereof to form a gentle entrance portion 13 and an exit portion 14. Also, one provided with an installation portion 15 at the lower end portion and a hanging portion 16 at the upper end portion is used. The artificial dark path tube body 10 is firmly installed on the ground G at the installation portion 15 at its lower end portion, and the hanging portion 16 at the upper end portion is firmly hooked and stabilized at the high place H on the tree. At this time, the entrance portion 13 and the exit portion 14 are gently arranged at an angle less than right angles and parallel or low with respect to the ground G and the high place H, respectively.

[0026] When installed as described above, the cat E and other predatory animals E that can pass through the artificial dark path tube body 10 can quickly rush up through the inside of the artificial dark path tube body 10 from the ground B of the action path without being found and enter the high place H on the tree where the long-tailed tits B and other wild birds B gather. The long-tailed tits B and other wild birds B gathering on the tree will be suddenly attacked by the real natural enemy, the predatory animal E, so a great fear will remain and they will not approach that tree thereafter.
