WHAT IS A BIRD OF PREY?
No Comments
Birds of prey are not the only birds that hunt for their food, have hooked beaks or eat meat but they are the only birds that do all of the…
Both audible and silent electronic bird deterrents have become a very popular alternative to traditional forms of repellents such as bird spikes and netting.
The reason for writing this blog is that we have daily enquiries about audible and ultrasonic devices and how they differ.
Our sonic devices are audible. This means that they can be heard by humans. Audible/sonic devices are extremely effective and cover larger areas than ultrasonic(silent) devices.
Some of our audible devices give up to 30 acres of coverage! They are not ideal for built up, residential areas but can still be an option if using a dual sonic/ultrasonic device by adjusting the volume to blend in with the surrounding environment which is often the sound of loud bird cries anyway.
Examples of situations where sonic devices are effectively used are on farms, large open areas and marinas. Most of the sonic devices have recordings of bird distress and bird predator calls such as eagles. You can have these turned up very loud or at a lower volume setting but it is best to have it at a volume that sounds natural and similar to that of the surrounding birds. You can also have the device set to day, night or 24 hours. These recordings give birds the impression that the area is dangerous and a “no go” zone .
Silent (ultrasonic) devices are not heard by 96% of humans but are very irritating to birds.
Our devices operate at a frequency of 15-25 khz and some of our commercial products as much as 30 khz. This is outside the range of normal human hearing.
These ultrasonic waves make the birds very uncomfortable and consistent exposure results in the birds moving on to find another home. Ultrasonic sound waves work best in line of site so at times it may be necessary to reposition the device.
Ultrasonics are extremely effective on swallows and pigeons.
At times you may need to be persistent as sonic and ultrasonic bird repellers do not harm birds but just makes them feel very uncomfortable, it may take anywhere from 1 day to 3 weeks to break their habit. It all depends on how stubborn and persistent they are. Please visit our blog on “How to use electronic bird repellers effectively” to learn more about how to get the most out of your device.
