Description

  The present invention relates to a method and apparatus for repelling crows, wild boars, etc. in the field of wildlife prevention.

  Bird damage is widespread and diverse, including damage to crops and fruit trees by birds such as small birds, chicks, and crows, as well as damage to crops such as debris, monkeys, wild boars, etc. The main target is damage caused by crows and wild boar, which has a huge impact on the human living environment.

  Various measures and equipment to reduce the damage caused by crows have been devised, developed, manufactured, sold, and used. In general, (1) a method of making a victim surrounded by a net and making it inaccessible, (2) Method to reduce the number of attacking wings by capturing with a spear, etc., and at the same time give fear of capture and killing (including gunshot killing and drug killing), (3) Spontaneous and reflexive A method of intimidating and dissipating using the light of the light (see, for example, Patent Document 1), (4) a method of intimidating and dissipating by emitting explosion sounds, gunshot sounds, bird screams, etc. (for example, see Patent Document 2), 5) There is a method to hang a carcass or similar (such as a piece of black cloth) to give fear.

  According to the view of public institutions that have investigated and studied the effective effects of these methods and equipment, (3) the following methods, that is, the methods of repelling crows by intimidating or giving caution, are initially effective. We conclude that there is no one that can maintain or demonstrate its efficacy for a long period of time even if the crow learns harmlessness to itself by reducing or losing its efficacy.

  Compared to this, there are not so many repelling methods for wild boars, and it is summarized in a method of preventing electric intrusion with a plate wall or a fence, or by extending an electric wire and causing a current to flow through the boar (see Non-Patent Document 2). However, it is difficult to say that all of them provide effective methods for preventing the invasion of wild boar.

  As is clear from the above discussion, the problem that needs to be solved for crows is that the crows are harmless to themselves, even if the crow payout method and the effectiveness of the equipment are effective at the beginning. Learning sexuality reduces or loses its efficacy, and can solve this problem by using crows rather than devices and devices that have been used to threaten and warn crows. It can be said that it is a method and equipment based on the behavior of crows that does not establish learning.

  For wild boars, it can be said to provide a new method / equipment with a greater repelling effect.

Means to solve the problem

  With regard to crow prepayment, the crow prepayment effect is achieved by containing crow learning that diminishes or loses the efficacy of the device, and always encounters crow prepayment equipment when the crow is in an unlearned state. The object is to provide a method and a device that can be maintained and exerted permanently.

    In addition, for wild boar, it is to provide a new method that surpasses the above-mentioned known method. Preferably, it would be advantageous if the same crow pay-off method and equipment described in the previous section can be applied. The invention could achieve this.

The present invention was created based on the results of observations and research on the behavior, ecology, and prey attack of birds and beasts, especially crows, over many years. The first special mention behavior of crows is mania and observation behavior. Crows are extremely timid, and because of this behavior, they show excessive awe, startle, and vigilance against the light and sound of the above-mentioned sudden launches that are set up near the target prey.
On the other hand, according to the general theory, the degree of intelligence is high and curiosity is strong, and there is a habit of starting to observe the phenomenon from a remote place where damage to the self does not occur. And if you understand and recognize that it is just a phenomenon by observation and there seems to be no harm to self, you will approach it by walking with caution and confirm that there is no real harm and approach this prey. Start beggar. In that case, the approach to the prey is not a flight, but by foot without exception. In order to prevent or invalidate this learning, it is only necessary to stop the threatening phenomenon when observing a crow so that the recognition of the phenomenon by observation does not hold.

  What a crow is afraid, startled, or vigilant is, of course, concentrated in elements that suddenly and greatly stimulate vision and hearing, that is, light and sound. The light should be flashy, and the sound is suddenly pronounced, such as gunshots, explosions, and human anger. In other words, it does not deny methods and equipment that have been devised and developed so far, and it is possible to use and utilize them.

  The learning prevention method based on the behavior of the above crow is as follows. In other words, if crows do not let crows observe the state in which the prepayment device emits a threat element, learning of crows will not be possible, so this is the basis of the method, and in addition, the threat of the optimal device at the unexpected time of the crow If you always perform the function and startle and repel, the crow will not be able to extinguish the startle or fear by learning, and the crow prepayment method and equipment that can always give startle and fear to the crow will be established Become. This is the first skeleton of the present invention.

  First, it is desirable that a crow be brought close to the damage control target object without warning. As mentioned above, it is a general behavior that crows descend once near the prey and walk up to the prey while walking, so it is better not to display the threat element until it approaches the prey. Intimidate elements are fired when approaching nearby, 2-5 m. The most effective is the simultaneous firing of flash and intimidating sound, and the intermittent effect of flash is great. The device developed as the device of the present invention incorporates an infrared sensor, a flashlight, and a tape recorder, and this device is installed in front of a path where a crow approaches on foot. When the crow approaches 2-5m near this device, it detects it with an infrared sensor, and fires a threatening sound from an endless cassette tape that records the flash of the flashlight and the voice of the person set on the tape recorder. Let the crows startle, awe, and suddenly dissipate. After the crow has dissipated, the infrared sensor will go into a non-detection state, so flashing and intimidating sound will stop. In this state, the threatening element is in the non-expressed state, so it is impossible for the crow to learn by observation, so there is no decline or loss of effectiveness of the prepayment method and equipment by learning the crow.

  Secondly, the crow's habits that should be noted are a little overlapped with the above, but it is confirmation of safety during an attack by watching and observing from a high place. This watch and observation plays an important role especially when attacking a prey with a small number of one or two wings and also when attacking in a flock with many wings. The pattern does not change even when a small number of one or two wings attack, so when describing the case of attacking with a large number of wings, first, one to three crows are close to the prey where the prey can be observed well Stop at a high point (high treetops, utility poles, steel towers, etc.), watch and observe the state of the prey, and if it is confirmed that it is safe enough, it will give some signal / instruction to nearby friends. (Unfortunately, at this stage, it is not possible to elucidate what kind of voice or crow language is used for this signal / instruction.) In response, the waiting crows attack the prey all at once. Therefore, it is possible to eliminate the invasion of fellow crows by dissipating the crows of the lookout / observer.

  As a countermeasure against the behavior of this crow, only threatening by light irradiation is possible. Normally, there is a distance of about several tens of meters to the point where the watch and observation crow stops, so it is difficult to adopt a startle sound due to concerns about sound pollution. A method using solar reflected light and a visible light laser pointer (regulatory product) that can be reached without dropping is effective. The sun reflected light is effective when irradiated with a hand mirror (including a concave mirror), but the existence of solar irradiation is a necessary condition, and the visible light laser pointer does not have this drawback, but the light intensity is the sun. It is not as strong as light and its power is slightly reduced. For convenience, it is also effective to use bullets with air guns or rubber guns, but this is a reference method for legal and safety reasons.

    Even in this law,

As described, it is desirable to detect the location of the guard / supervisor, and suddenly irradiate the spot to surprise and scare the crow, but at present, it exists at an unspecified point at a long distance. Since it is practically difficult to detect and identify crows with equipment, the method of the present invention is based on the principle of threatening and dissipating the crow as a supervisor by detecting and identifying by human power and manually irradiating light. . In this method, it is needless to mention that it is necessary to immediately stop the light irradiation and stop the observation and learning of the crow after the crow is threatened or dissipated by light irradiation. .

  Wild boars, like crows, are extremely vigilant and are not supposed to approach humans. In addition, learning ability and exercise ability are high, and it is said that the number can be counted according to one theory. Food is omnivorous and eats leftovers at home, which is very similar to crows. Therefore, the above-described prepayment method / equipment effective for crows can be applied to a boar as it is.

The invention's effect

In the present invention, the crow uses the basic and unchanging behavior of crows to recognize that threatening elements directed at the self that attack the bait are harmless by observation and learning over time. However, by making this observation / learning unsatisfactory, it solves the problem of decline or loss of the effectiveness of the prepayment equipment, which the conventional crow prepayment equipment could not overcome, and the effect of crow prepayment diminishes or disappears We were able to realize a crow repatriation method and equipment that could be maintained and demonstrated without any problems.
In addition, this method can be applied to a wild boar as it is.

In addition, when a crow attacks a prey, one to three watchmen observe the prey condition at a nearby high point, and uses the habit of attacking fellow crows according to the safety confirmation instructions of this watchman. By removing the crow that serves as the watch tower and the command tower by irradiating light, it was possible to establish a method to make it impossible to attack the crow's prey.
This method does not apply to wild boar because wild boar does not have this behavior.

  The embodiment of the present invention method will be described. First, the bird and beast repelling machine according to the present invention is installed in front of the prey in the intrusion path where the birds and beasts aim at the prey. As shown in "Equipment Circuit Block Diagram" in Fig. 1, the birds and beasts repelling machine has an infrared sensor: 1, flashlight: 2, and tape recorder: 3, together with a built-in power supply: 4, which is usually connected to the power supply. In contrast, 1 is “ON” and 2 and 3 are “OFF”. The infrared detection direction of 1 is directed toward the invasion direction of the target bird and beast. When the target bird and animal approaches a distance of 2 to 5 m, the infrared rays emitted from the sensor are detected and 2 and 3 are turned “on”. Suddenly dissipate the target birds and beasts by flashing the flashing light and suddenly performing the action and pronunciation of 3. Since the infrared sensor is not detected after the target birds and animals are dissipated, 2 and 3 are in the “off” state, and the flashing flashing of the flashlight and the operation / sounding of the tape recorder are stopped. In this way, crows or wild boars cannot learn this because they cannot continue to observe and experience the launch conditions of the startle elements (light and sound) fired from the repelling aircraft. As a result of the startle and retreat, a repulse method that retains and exerts its effects is realized.

  For crows, when this machine was installed in a place where the spilled feed from the poultry farm and the feed pipe intake part of the outer wall of the poultry house was constantly attacked, several of the first attacks were surprisingly dissipated. After that, there was no attack. After the first retreat, two crows stopped on the roof of the facing chicken house and observed this machine. After a while, they flew away, and after that, they attacked the spilled food for chickens. The state that does not come to observation continues.

  For wild boars, when this machine was installed on the gently sloping surface in front of a vegetable field that occasionally invades, no traces of attack have been observed since then. Wild boar attacks are mainly in the night when there is no human figure, so we can not observe the behavior like a crow, but we can clearly confirm the fact that the attack has stopped.

  In addition, two crows that are standing on a treetop near a high tree near the pear garden and are watching normally at the time of the attack are dissipated by reflecting the sunlight with a plane mirror, and then irradiated again at a later time. I was dissipated. As a result, we were able to prevent the crow prey attack that was conducted more than once in advance. In this case, however, the supervisor crow reappears the next day, and since there was a process of immediately dissipating only with the same signs of irradiation, it is judged that the crow repelling by this method is effective to continue for a certain period of time. .

  The method and device of the present invention relate to the repelling of crows and wild boars, etc., among the animals that damage human living environments, whose characteristics are timid, highly intelligent and have a habit of scaring people. The animals that cause damage to the living environment are not limited to these two species, but there are various animals such as deer, monkeys, and bears. Since these characteristics are slightly different, they are excluded from the subject of the method of the present invention and device application. However, there is a great social need for damage control by these animals. On the other hand, even if it is difficult to apply the method and apparatus of the present invention as they are, it is considered that there is a sufficient possibility that a similar repelling effect can be realized by slight modification or addition / combination of other methods. This is an issue for the future.

  Furthermore, since the method of the present invention is basically a security method and equipment, it is expected that there is a possibility of application to human beings in a modified form. Even at present, there is a security device that combines an infrared sensor and a surveillance camera, but a device that combines with a device that performs threatening or warning by voice has not been developed, and an effective method is expected to be developed. Even though these methods and equipment are not positioned as perfect security equipment, there seems to be an expectation that demand for cheap and effective practical security equipment will be opened up.
