Bird Songs Visualized

Bird songs take on a whole new dimension when you see them visualized in a spectrogram. Time moves from left to right; higher pitches are higher up on the chart.

The syrinx, or vocal chords, of many birds can make at least two tones at once. 

The following video has a sliding spectrogram matched to a song. (Link to YouTube)

 The best spectrograms are the free Merlin Bird ID app produced by the Cornell Bird Academy
