Glaucous macaw

The glaucous macaw (Anodorhynchus glaucus) is a critically endangered or possibly extinct species of large, blue and grey South American parrot, a member of a large group of neotropical parrots known as macaws. This macaw is closely related to Lear's macaw (A. leari) and the hyacinth macaw (A. hyacinthinus). In Guarani, it is called gua'a hovy after its vocalizations.
