About the Macaulay Library

The Macaulay Library is the world's largest and oldest scientific archive of biodiversity audio and video recordings. Our mission is to collect and preserve recordings of each species' behavior and natural history, to facilitate the ability of others to collect and preserve such recordings, and to actively promote the use of these recordings for diverse purposes spanning scientific research, education, conservation, and the arts.

Using the Archive


Scientists worldwide use our audio and video recordings to better understand and preserve our planet. Teachers use our sounds and videos to illustrate the natural world and create exciting interactive learning opportunities. We help others depict nature accurately and bring the wonders of animal behavior to the widest possible audience. It is an invaluable resource at your fingertips.

Building the Archive


This archive grows through the efforts of dedicated recordists who share their recordings with the community. We encourage recordists around the world to contribute their recordings and data to what has become an irreplaceable resource. Once you share your recordings, we take our job seriously, ensuring that your recordings and the work of others will be preserved for generations to come.

Field Recording


We provide training, equipment, and resources to help document the diversity of life with sound and video. Through workshops and informal training sessions, we teach field techniques and share the technical knowledge required to meet the challenges of recording the behavior of birds and other animals in the wild.
