Glaucous macaw
Critically Endangered or Possibly Extinct
The glaucous macaw is a large, predominantly blue and grey South American parrot, closely related to Lear's and hyacinth macaws. Its typical coloration is described as "glaucous," and it is characterized by a long tail, large bill, and a distinctive yellow eye ring. This species is critically endangered or possibly extinct, with its decline attributed to trapping for the pet trade and the destruction of its primary food source, the yatay palm.

About Glaucous macaw
The glaucous macaw (Anodorhynchus glaucus), also known in Guarani as gua'a hovy, is a large species of South American parrot that is now critically endangered or possibly extinct. This macaw is distinguished by its predominantly pale turquoise-blue plumage, a large greyish head, and a long tail. The term "glaucous" refers to this characteristic coloration.
Description and Features
Measuring approximately 70 cm (28 inches) in length, the glaucous macaw possesses a robust build typical of macaws. Beyond its overall blue and grey coloring, notable features include a prominent yellow, bare eye ring and distinctive half-moon shaped lappets that border its mandible. Its bill is large, suited for cracking tough nuts.
Range and Decline
Historically, the glaucous macaw inhabited a wide range across South America, including north Argentina, south Paraguay, parts of Bolivia near Santa Cruz de la Sierra, northeast Uruguay, and Brazil. Its decline began in the 19th century, primarily driven by two factors: intense trapping for the lucrative wild bird trade and the widespread destruction of the yatay palm (Butia yatay), which constituted its main food source. This habitat destruction and loss of food resources led to a drastic reduction in its population.
Conservation Status and Sightings
By the 20th century, the species had become exceedingly rare. Only a few unconfirmed reports of wild birds surfaced during this period. Expeditions in the 1990s to its former range in southwestern Paraguay failed to find any evidence of its existence, and older residents recalled the species last being seen in the 1870s. Despite the existence of suitable habitat in areas like El Palmar National Park in Argentina, no credible rumors of its continued presence have emerged in recent decades. A 2018 study, considering extinction patterns and habitat destruction, recommended that the glaucous macaw be uplisted to Critically Endangered – Possibly Extinct, reflecting the extreme rarity and lack of confirmed sightings since the 1980s. While some anecdotal reports and suggestions of its continued existence in remote areas of Bolivia persist, these have not been scientifically verified.
