About the Search for Lost Birds
We strive to understand and promote species of birds that are currently ‘lost’, meaning that at least 10 years have passed since they were last confirmed by photographs, sound recordings, or physical documentation. The Search for Lost Birds is a global partnership between American Bird Conservancy, Re:wild, and BirdLife International.
