The Spix Macaw has been brought back from extinction

The Spix's Macaw, a bright, blue parrot from Brazil, was declared extinct in the wild over 20 years ago. But scientists have been breeding the birds in captivity and have finally reintroduced them back into their natural habitat. Biologist Tom White, technical advisor for the rescue project, discusses how the bird was brought back, and evolutionary biologist Tori Herridge shares the ethical questions that need to be considered for such a project.
