Original: Declaring a bird extinct: The median wait is 36 years after the last sighting
A new analysis finds that ornithologists wait a median of 36 years after the last confirmed sighting of a bird before officially declaring the species extinct. The long lag reflects caution in classification, since proving that no individuals remain is extremely difficult, and premature declarations can cause conservation funding and legal protections to be withdrawn too early.
Why now: The strikingly long delay in formal extinction declarations prompts debate about how conservation science classifies lost species.
