The Avian Interlopes is the reason behind the United States spending approximately $1.9 billion every year in damage control and crop losses. Farmers are putting in efforts into protecting crops from damages by birds, but they cannot possibly stand like scarecrows in their fields.
Several research studies and experiments have been carried out in this field, and researchers have ultimately landed on one solution. The solution involves the use of speakers for sending out buzzing noise to protect the farm fields from damages caused by birds.
Use Of Sound For Protecting Crops
The idea of using sonic protection for protecting crops from large scale damages caused by birds has worked for many farmers. Since feathered pests vocalize to alert one another about sources of food and predators, biologists Ghazi Mahjoub and John Swaddle, along with Mark Hinders, an acoustician from the College of William & Mary conjectured that disturbing these conversations could increase the vigilance of the birds.
Protecting Crops Through Sound Is A Long-Lasting Method
It would further leave very little time for dining and loitering. Indeed, in different tests conducted at aviaries of the college, patches of food exposed to the sonic shield for eight hours showed an approximate 46% drop in the presence of the birds in comparison to control groups.
It proves that the use of sonic protection for keeping birds away from crops can serve as a safe and long-lasting method. It is way better than the other techniques and tactics used for the same thing. These include poisons and hi-tech pyrotechnics.
Several other evaluations and experiments are being carried out at Virginia airports and agricultural fields. There are even plans for testing the sonic shield on massive urban structures like skyscrapers and cell towers. These plans are in place only to prevent bird strikes.
Many researchers are playing an essential role in exploring the way sonic protection could bring about a reduction in crop losses throughout sub-Saharan Africa.
The Viable Comparison
Mark Hinders compares the effect of the device to be present at a get-together or cocktail party. Many people are talking to each other at a party, making it very difficult for one individual to pay attention to what the others are saying.
The device works by not being especially loud. The gaps in the conversations of the attendees have lots of noise. Now, if the party gets crashed, the sonic shield works towards saving the crops and the birds as well.
Room For Further Research
It would be wrong to say that further research is not being carried out in this field. Though the sonic protection has been out in place and is also being used to prevent crop damage, further research is required to come up with something more dependable.
Even if farmers can use the device in their fields, they will require proper training to do so. So, a user-friendly and convenient tool is necessary for the farmers to save their crops from large scale damage caused by flying pests.
