The sounds in this composition will never again be heard in the wild. All of the species audible in this piece—ten birds and two frogs—are now extinct. You are able to hear these sounds because the creatures that made them went extinct during the era of recorded sound; this is a unique moment in the history of human-driven extinction.

This sound installation was presented at the IMRC Center at the University of Maine in Orono, Maine, United States on May 3, 2018; this recorded excerpt of the same installation in the same space was made the following week on May 9.

The value of the existence of these recordings cannot be overstated. The recordings heard in this piece were generously provided by the following research institutions:

The Macaulay Library of the Cornell Laboratory of Ornithology, http://www.birds.cornell.edu/.

The Amphibian Foundation, Atlanta GA, http://www.amphibianfoundation.org/.

Data on these species was drawn extensively from the International Union of the Conservation of Nature’s Red List of Threatened Species. Version 2017-3. HTTP://www.iucnredlist.org. Accessed on 29 April 2018.
