A music and science lover has revealed that some birds can store and retrieve digital data. Specifically, he converted a PNG sketch of a bird into an audio waveform, then tried to embed it in the song memory of a young starling, ready for later retrieval as an image. Benn Jordan made a video of this feat, sharing it on YouTube, and according to his calculations, the bird-based data transfer system could be capable of around 2 MB/s data speeds.
But this isn’t true. Just because a signal is modulated doesn’t mean it can’t be distorted.
A spectrogram is just showing that arbitrary data can be sent though this channel. It’s literally a form of modulation.
