Visualising birdsong as a three-dimensional data array
A short Instagram reel by Lucio Arese visualises the song of a hemp bunting (Linaria cannabina) as a scatter plot, where pitch, amplitude, and timbre map directly to spatial position and density. The post argues that birdsong is not creativity but a tightly structured signal carrying territorial, genetic, and hormonal information: a 'biological blockchain' rather than a song.
