By slowing down the songs of the Crested Oropendola (seen here) and the Tui, all the notes and harmonies stand out. While these details normally rush past the human ear faster than our brains can process, birds are alert to the subtleties of other birds’ songs.

This show was produced by World According to Sound. BirdNote and World According to Sound are teaming up for an immersive, 70-minute, virtual event about the sounds of birds. Learn more at BirdNote.org.
