We experience the evolution of technology first-hand every day, including through our own smartphonesand also thanks to various apps that animate them. By now we know apps that perform practically any task, but today we discover one that perhaps you have never seen it yet.
We are talking about BirdNeta very particular app that is capable of identify birds based on their singing or chirping. We tried it in the last few days and we’ll tell you why we liked it.
BirdNet is an app developed by Cornell Lab of Ornithology, a specialized ornithology laboratory at Cornell University, located in Ithaca, New York. Let’s say it straight away so that we can understand it straight away reliability and accuracy of the app.
BirdNet aims to recognize bird species based on I sing that they emit. The app achieves this through ad hoc developed algorithms, which allow it to recognize birds by analyzing them spectrogram relating to their singing. The spectrogram is essentially the representation of the frequency components of sound.
Clearly each bird emits a song with a different spectrogram, and this allows its recognition.
The operation is quite simple: the app record all sounds that arrive from the environment, for a time decided by the user; subsequently the user must to select the part of the recording in which the song of the bird to be recognized was present, then just select the option Analyze And that’s it.
We tested the app in different conditions and recognition always occurred correctly impeccable. BirdNet also shows the level of recognition accuracy. We also tried to record a human whistleand the app correctly categorized the sound as coming from a human.
The app includes a section that collects all the awards carried out, with accompanying audio recording. For each known species, a quick link to the relevant one is then proposed Wikipedia page to find out more about the identified species. The section of the app that allows you to consult all the information is also very interesting common bird species in your own area of residence.
In short, BirdNet is an app really valid and we recommend it not only to those who are passionate about ornithology. Interaction with nature is obviously a fundamental aspect of our lives and apps like BirdNet do nothing but improve it, also in terms of awareness of what surrounds us.
The BirdNet app is available at free download for Android devices. There are no advertisements, and there is no subscription to continue using it without limitations. In short, all you have to do is try it.
