This show pairs birds that make sounds on opposite extremes: the highest-pitched bird, the Black Jacobin hummingbird, duets with the Southern Cassowary, one of the lowest-pitched birds. The faint, buzzy song of the Grasshopper Sparrow joins the voice of the White Bellbird, the loudest bird in the world.

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.
