The bird repeller can be called an indispensable device for both agricultural enterprises and ordinary owners of summer cottages. Nevertheless, there are still people who are not aware of the existence of such a technique that impedes the finding of pigeons, crows, sparrows, swallows and other birds in the territory used to grow vegetables, fruits, berries or flowers. Today we will talk about how the repellent device works and how to make the right choice at the time of purchase, given the wide range of equipment provided by modern manufacturers.

About product
The need to drive the birds away throughout the entire existence of agriculture. Previously, due to the lack of proper technical capabilities, people coped with improvised means: they created dolls - a scarecrow in the form of human figures, launched kites, representing a painted bird of prey, planted a dog near the “protected” territory or placed stuffed animals of “dead” birds, signaling relatives about danger. The effectiveness of the methods described was extremely doubtful, so modern engineers thought about designing another "miracle of technology."
Bird repellers today are automated devices of various types that can drive away “flying guests” from the territory where they are undesirable or unacceptable, in particular airfields, large fields of agricultural enterprises with crops grown on them, and so on. In addition to immediate immediate deterrence, such devices can prevent the construction of nests within the radius of their "effective" coverage. It is worth noting that this kind of equipment is absolutely safe for birds and people who are not far from a functioning device.
By type of action, repellers are usually classified into:
- ultrasound guarding a given area with ultrasound (maximum silent devices, but traditionally having a small area of "effective" coverage);
- bio-acoustic, the principle of which is based on imitation of the alarming screams of birds scaring off their relatives (a high degree of effectiveness in scaring birds off is combined with an undesirable excessive volume of direct operation of the device even at a minimum level);
- gas installations that scare away unwanted "guests" with sound "shots" (a large radius of the "effective" coating is the main advantage of this type of device, it is not able to make up for the disadvantage associated with the lack of a motion sensor that responds to birds approaching).
How to choose
In choosing a repeller for birds, a potential user must adhere to the basic criteria that are considered to determine the quality of equipment of the segment in question:
- Type of device. In this case, it would be advisable for the buyer to choose a universal device that is effective in combating various types of birds. These are ultrasonic and gas installations. Bioacoustic devices should be acquired if it is necessary to scare away a specific type of bird (pigeons, ravens, sparrows, etc.), because of their imitation of the cries of specific "relatives".
- Radius of action. The larger the radius of the “effective” coating, the more high-quality repeller will be considered. However, in this matter it is also worth considering its type. So, for ultrasonic devices, the optimal indicator would be 80 - 200 m2, and for sound guns - 10,000 - 20,000 m2.
- Type of power repeller.Most of the technology in this segment is powered by a 110 - 220 V power supply, however, there are models that can function correctly both from a power outlet and from a powerful battery. The choice in favor of the latter type of devices will be optimal, due to their versatility, which increases the degree of comfort for the user.
Having an idea of the principle of operation and the key parameters for choosing a repeller for birds, it is advisable for the buyer to pay attention to the following list of top models of the considered gadgets, considered the most high-quality representatives of their class.
