Most of the bird sounds you hear on BirdNote come from the Macaulay Library, a vast collection of over one million bird calls and songs curated by the Cornell Lab of Ornithology. The library relies on both professional field recordists and dedicated volunteers to capture the sounds of birds all over the world.

Support for BirdNote is provided by Marjorie and Ed Ringness from Seattle, Washington — and generous listeners around the world.
