Fly Away Birdies Humming Line produces a sonic net. This does not have to be loud
because it is a combination of waveforms. These waveforms are called colored noise. This forms both a non-constructive and constructive interference with how birds talk to each other. This sonic net technology discourages birds from flying into or spending time in the targeted area.
The impact to the birds is like talking in a crowded room. And since they cannot understand each other they go somewhere else.
Initially our objective was to displace problematic birds from agricultural loss due to pest bird foraging and displace nuisance birds that cause extensive repair and chronic clean-up costs. Early tests at our 50 farms around the country indicate that our technology is effective and that birds do not become accustom to the sound.

For Agriculture Bird Control - The Fly Away Birdies line is a humane and easy to use bird repellent. It is an effective bird deterrent, that emits an ever varying sound and vibration that birds won't go near.
The sound it makes changes so birds can not get used to it. It is safe, simple, durable and easy to install. You install Fly Away Birdies line between upright stakes. The line will emit humming sounds when you have a slight gentle breeze and will get louder as the wind picks up. Fly Away Birdies line is harmless to crops, birds and animals.  When to install: Install at fruit set. Remove from field and re-spool after harvest.  How to install: Install humming line between in row uprights 15' to 30' apart. Pull line to remove slack. Avoid twisting line.
Low crop use: For shorter crops, place lines on 10' to 12' row centers with in row uprights 15' to 30' apart. Humming line should be 24" over canopy.
Brambles,  vines and trees: Place the lines above crop or between rows 8' to 10' above ground level. Uprights should be 15' to 30' apart.  Removal: after harvest, take the humming line down and either throw it away or recycle it. Note: The higher the humming line, the farther the harmonic sound will travel. You can hear sound up to several hundred feet away. Want to buy the Fly Away Birdies Humming Line? ClickHere.

Precision Agriculture (precision Ag - precision farming) is said to be everything that makes the practice of farming more accurate and controlled when it comes to the growing of crops and raising livestock. Precision agronomics is another important term related to the combining of methodology with technology. It provides more accurate farming techniques for planting and growing crops. Precision agronomics can involve Biodynamic farming, including using Structured Water or what we sometimes call Grow Water and Flyaway Birdies which create a sonic net over the specific crop that you want to eliminate bird damage.
