Glaucous Macaw: South America’s Turquoise Blue Mystery

Estimated reading time: 6 minutes

The glaucous macaw is a critically endangered, vividly colourful bird native to South America. Also known locally as the arara azul pequena, they boast striking pale turquoise-blue plumage. These large neotropical macaws feature a distinct yellow eye ring and half-moon lappets around their formidable beak. Historically, they formed noisy colonies on rocky cliffs and possessed a unique, loud vocalisation that earned them the Guaraní name “guaa-obi.”

However, the survival of the glaucous macaw is tragically uncertain today. Rampant palm oil agriculture, aggressive gold mining, and widespread logging completely decimated their crucial yatay palm grove habitat. Furthermore, illegal wildlife traffickers heavily targeted these beautiful birds for the exotic pet trade. Therefore, saving rare canopy species requires us to vigorously boycott destructive corporate supply chains and defend South America’s fragile forests.

Red list classification: Critically endangered

Locations: Argentina; Brazil; Paraguay; Uruguay

Appearance and behaviour

The Glaucous Macaw Anodorhynchus glaucus are known for their blue plumage and distinctive grey head, is a critically endangered bird native to South America. With a length of 70 cm (28 in), this beautiful macaw features a long tail and a yellow eye ring. Despite their large size and stunning appearance, the bird is rarely seen in the wild today due to habitat loss and illegal hunting.

Threats

The Glaucous Macaw faces have faced significant human-related threats that have driven them to the brink of extinction. This is an enormous tragedy.

• Deforestation: Widespread logging, gold mining and palm oil agriculture led to the destruction of crucial yatay palm groves.
• Poaching: The bird was heavily targeted for the illegal pet trade due to their striking appearance.
• Deforestation: Conversion of forests for palm oil growing along with gold mining and cattle/beef agriculture has destroyed many habitats for the Glaucous Macaw.

Geographic range

The Glaucous Macaw was historically found across Argentina, Paraguay, Uruguay, and Brazil, preferring river basins with yatay palms or open forests. They relied on these palm groves for nesting and feeding. Their disappearance from these areas due to logging, agriculture, and hunting is a sad reminder of the importance of habitat conservation. We cannot let them disappear!

Diet

Primarily feeding on the yatay palm nuts, when these are unavailable the Glaucous Macaw also eats alternative fruits and seeds. The loss of these critical palms directly impacted the bird’s survival and forced the remaining macaws to seek alternative, often rare food sources.

Mating and reproduction

Researchers don’t know much about the breeding behaviour of this species due to their rarity. It is thought they nested on rocky cliffs in colonies, likely laying eggs in secure nests. Their colonial nature made them especially vulnerable to hunters.

Support Glaucous Macaw by going vegan and boycotting palm oil in the supermarket, it’s the #Boycott4Wildlife
