For the last 15,000 years, after we killed all mammoths and switched to a plant-grain-based diet, we've been chasing the birds from our crop fields. Now, it's time to call them back, at least in the form of recorded sound and give the plants what they like to listen to most, bird songs.

Birdsong has been a subject of fascination for centuries, captivating us with its beauty and complexity. But recent research suggests that these melodious tunes could have a profound impact on plant growth.

Research suggests that birdsong can positively influence crop yields by stimulating plant growth and increasing resilience. This occurs through various mechanisms, including the stimulation of stomatal openings for improved photosynthesis and the potential for birdsong to affect beneficial soil bacteria. 

Birdsong is a form of sound wave, and sound waves are essentially vibrations traveling through a medium. These vibrations can potentially influence the activity of these beneficial bacteria, enhancing their plant growth-promoting effects. They can also indirectly improve plant growth by inducing plant resistance to various biotic and abiotic stresses, such as pathogen attack and heavy metal contamination.

THE IDEA IS TO MAKE A CUSTOMIZED COMMERCIAL SILENT DRONE, EQUIPPED WITH A LOUD SPEAKER TO PLAY BIRDS' SONG FROM 5 AM TILL 8 AM, TO MIMIC BIRDS AND TO HELP PLANTS GROW HEALTHIER WITH MORE YIELD.

The whole process should be automated and led by AI, as the drones should fly over the fields for 2-3 hours and land back at the base.

Numerous researches support this idea, web search>"birds song plant growth".

The technical process should be described in a few words...make it simple.

1. Provide decent *.MP3 or *.WAV files of both birds' songs, they are all around...What should be avoided at any cost is the repetition of those songs, as the plants could maybe read our cheat game.
2. Order a customized AI commercial silent drone, equipped with loud loudspeaker and its own internal USB player to reproduce bird songs
3. Train own AI model for drone driving, by machine deep learning.
As this task is not complex, this would not be difficult.
4. Prepare the drone stations for keeping the drones.
5. Train local farmers to operate drones.
6. Start drone flying over the cropfields.
7. Collect the 15-25% more of the yields and biomass.

How many drones will cover which area is the topic to discuss later, but roughly speaking, it is about 1-2 drones to 2-4ha (5-10acres).

As one drone unit would cost 750-1000€, and the average electricity bill for 6 months would not exceed 100€/ per drone, we could say that the initial investment will give back just within one year, while the next years will be clear profit, assuming that one drone could last at least 10-15 years with proper maintenance.

Also, we could value not just financial profit, but also plant wealth.

They will be happier and satisfied. Just imagine yourself living with or without music, radio, TV, internet...well, same with plants. Birds are their home stereo.
