Last week, the 2nd to last to last wild born Spix's Macaw died. The 40 year old parrot, named Presley, was thought to have inspired the film Rio- about a pet parrot who is discovered and taken to join a captive breeding programme.

Most of these birds are closely related, so Presley was important because he was genetically very different. Unfortunately, although it was attempted, he never bred successfully, so his death is a huge blow for the future of Spix's Macaws. Like this podcast?
