Who should have a say in which species are saved? The California condor offers lessons for a global biodiversity treaty

In 1987, biologists captured the last free-flying condor to transfer it to captivity, and the largest flying North American bird species was officially declared extinct in the wild. Today, after decades of coordinated efforts and millions of dollars spent on captive breeding and reintroduction efforts, more than 300 condors have been restored to their natural environment.
