As of now, Amazon, Zipline and Flirtey continue to use drones for deliveries. However, there is also a group of ornithologists at Gettysburg College in Pennsylvania that has developed a different way to utilize unmanned aerial vehicles (or UAVs).
A New Use For Drones
By means of suspending a simple, lightweight recorder below a test DJI Phantom 2 quadcopter drone, Gettysburg College Environmental Studies professor Andrew Wilson. Along with them, two undergraduate students were able to study songbirds and later published their findings. The study was entitled “The feasibility of counting songbirds using unmanned aerial vehicles”. It found that the data on songbirds were pretty much comparable to that of a “standard count for most species.”
Why Use A Drone To Study Song Birds?
The initial reaction of the people was, why would you bother using a drone to study birds in the first place? The researchers have already provided their answer to this expected question.
This is because audio bird recordings are prior and made from ground-based recorders or recorders close to the ground. This is a traditional method that researchers claim to be limited by site accessibility and logistically constrictive. Instead of it put into the air where it is closer to the subject, the recorder was placed on the ground.
Aerial recordings, on the other hand, have greater visibility and range, as well as mobility. The new breakthrough method can be used to access sites that are normally not surveyed by terrestrial methods.
In other words, with the use of a drone, you can cover a lot more ground. You can even get microphones into hard-to-reach areas. Of course, constantly using drones to study bird songs does have an obvious drawback.
Disadvantage Of Using Drone For Studying Song Birds
As said in the study, excessive UAV noise can be a major hurdle to using UAVs for recording sounds. But the researchers are optimistic that technological innovations would be made to reduce motor and rotor noise. This will drastically solve and reduce this issue.
More Improvements On The Study
The study that the researchers conducted concludes that that UAV-based bioacoustic monitoring holds great promise. They are currently urging other researchers to consider further experimentation to refine the newly discovered techniques.
