The Glaucous Macaws (Anodorhynchus glaucus) are large South American parrots that are generally considered extinct or on the verge of extinction, as the last reliable sightings date back to the 1960. However, due to persistent rumors of sightings, this species is currently listed as Critically Endangered rather than being officially declared “extinct”.
