The World According to Sound: Antiphonal Duets
Some birds, especially those in the tropics, sing what are known as “antiphonal duets.” These are duets where there is a rapid alternation of notes sung by each bird. Sometimes there is just a gap of a few milliseconds between the part sung by each bird. The tight-knit duets help mating birds locate each other.
The World of Sound team took the duets of several pairs of wrens recorded by Dr. Nigel Mann and separated the parts of the two birds. By separating the vocalizations of each bird, you can hear how perfectly the two parts fit together.
At the end of the piece you hear a bird whose mating call never gets answered. It’s a Kaua‘i ‘ō ‘ō bird that was recorded in 1984 by James Jacobi. It was one of the last recordings made of an ō ‘ō bird. The species is now extinct.
We encourage you to listen with headphones on!
The World According to Sound is a live audio show, online listening series, and miniature podcast that focuses on sound, not story. Producers Chris Hoff and Sam Harnett create intentional, communal listening experiences as a way to “reclaim autonomy in a visually dominated world that is increasingly fracturing our attention.”
These recordings and more are a part of their listening series, an immersive listening party where audiences from all over the globe experience a world of sound together, beginning. The next event is titled “Solitude” and takes place on Thursday, March 10.

IRA FLATOW: Before we head out the door this hour, how about a treat? A soundscape from The World According To Sound podcast. And for this one, I highly encourage you to wear your headphones.
CHRIS HOFF: Dr. Nigel Mann recorded these two bay wrens doing the little call and response. Here’s the female.
And here’s the male.
Now they’re going to sing together. This is called an antiphonal duet, except now we’ve separated their songs.
These are actually two distinct birds. In 1984, James Jacoby recorded this kaua’i’ o’o bird. It’s a male calling for a female. But he never gets a response. This bird was the last one of its kind.
IRA FLATOW: These sounds are part of a communal listening series The World According To Sound is hosting this winter. For tickets to their 90 minute binaural events, visit theworldaccordingtosound.org.
