Glaucous Macaw
The glaucous Macaw is one of the rarest birds in the world. It is considered Critically Endangered, and may be extinct in the wild.
This bird has been reported by aviculturists from various countries, but the latest sighting was recorded in 1992. This alleged sighting occurred in the southwestern region of Paraguay, near the city of Corrientes. The bird was male.
Origin
The Glaucous Macaw is a parrot native to South America. It is endangered. This magnificent bird has a unique blue feather pattern and powerful beak capable of cracking open tough seeds and nuts. Glaucous macaws are known to form long-term monogamous couples and both parents assist in raising the chicks. The chicks are fed a diet of regurgitated food in the first few weeks of their lives, and then solid foods as the chicks develop. Parents play a crucial role in teaching the young macaws how to fly and forage.
The glaucous macaw is considered to be extinct in the wild, yet rumors of this beautiful bird's existence are still spreading all over the world. It is believed that the glaucous Macaw was extirpated in the 1800s due to logging and cattle grazing of yatay palm (Butia yatay) trees, where these birds primarily gathered their meals. It is currently believed that the glaucous Macaw has returned to captivity in the wild, where it is kept alongside its larger cousin Lear's macaw.
In terms of habitat, the glaucous macaw can be found in the sub-tropical forests of South America. They are typically located in areas that have numerous palm trees. They are also highly adaptable to a variety of forested environments. These beautiful birds are territorial and will protect the nesting and feeding area from intruders.
There have been a number of reports about the glaucous macaw through the years, but most are considered to be not reliable. The most recent report of a wild event is an avicultural acquaintance of Ridgely's who claimed to have witnessed four Glaucous macaws in Califomia. This is a ridiculous claim until it is substantiated with evidence. The absence of any reliable records of this bird in the past century has been a reason for many experts to conclude that it is likely extinct, yet they have always been willing to accept an extremely remote possibility of its existence (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it does survive, it will be extremely rare to see large numbers.
Habitat
The Glaucous Macaw is a magnificent bird, renowned for its huge size and turquoise-blue coloration. The tail and wings are long, enhancing its fluid and graceful movement. It is also a symbol of love and loyalty. Its beak, which is primarily black, has a distinct shape that allows it to crack nuts and seeds. These are a large part its diet.
IUCN has classified the Glaucous Macaw as Critically Endangered. It notes that there is a tiny population of this bird, and that it is at a the risk of becoming extinct. The species was once fairly widespread but now it is found in northern Argentina and southern Paraguay and north-eastern Uruguay and Brazil from Parana state southwards where it nestted in cliffs along major rivers.
The Glaucous Macaw was not rare in its limited area, even though there were no reliable sightings after 1830. The specimens were taken up until the year 1860 (in Corrientes). The last known living Glaucous Macaw was exhibited at the Buenos Aires Zoo in 1936 and is believed to have come from Brazil.
A reassessment of the historical records suggests that this species was a very generalist in its habitat preferences with a preference for areas of savanna that were interspersed with palm "islands" and areas of riparian forest along river systems. It was a specific food source for palm fruits, especially those of the yatay or chatay palm (Butia yatay) but it could also feed on ripe and unripe fruits as well as berries, nuts and vegetable matter. It nests on slopes that are steep or in cliffs, and also in tree cavities.
Like all parrots, this bird was social and probably gregarious. It was said that it could live to 14.4 years in captivity and was a reliable breeder who reproduced year after. In the wild, its lifespan was probably between 50 and 80 years. The species was a strong disperser of seeds and could be a factor in the success of the palm yatay in its natural habitats.
Feeding
The Glaucous Macaw is one of the most beautiful parrots. Its presence can have a strong impact on its environment. This huge South American bird is known for its vivid blue feathers and yellow eyes, as well as the distinctive teardrop-shaped lappet that brackets the lower portion of its beak.
Up until recently, very little was known about the feeding habits of the Glaucous Macaw. The first detailed references I have discovered are in two books by H.W. Bates' "The Naturalist on Amazons" first published in 1863, which describes his 11-year stay in Brazil. Later in his book "As Birds of the Brazilian Forests" Bates wrote about the similar experience. Both of them are about the Hyacinthine Macaw, Anodorhynchus Aureolarius. macaw purchase have no reason to believe that they don't apply to this species.
The Glaucous macaw is believed to be a specialized eater, consuming only palm nuts, but also tiny amounts of other seeds, fruits and vegetable matter. This species' diet was likely affected by the clearing of forests for farming and cattle-ranching by early colonists as well as the felling of yatay (Butia) palms from which it received much of its nutrition.
In the wild, it was common to find the Glaucous macaw in savannahs and subtropical forests in which palm trees were present. It hid in tree cavities, or on rocky banks and palm fronds. On average two eggs were laid in a clutch. eggs was laid and then incubated by the female.
The young Glaucous Macaws are altricial, meaning they depend on their parents to care for them until they become fully fledged and can fly. Both males and females are extremely dedicated to their young and will continuously hunt for food and protect them from predators.
Unfortunately unfortunately, the Glaucous Macaw has been eliminated from its entire previous range. The disappearance of this magnificent bird is likely due to the ongoing trapping for the pet trade and habitat disturbance, particularly the massive clearing of yatay palms from which it may have obtained its primary food source. The Glaucous macaw is classified as Critically Endangered.
Breeding

Glaucous macaws usually form long-term monogamous pairs with both parents taking part in raising the young. They breed in the dry season, which is when the food supply is at its highest. The female lays two to three eggs which are incubated by the mother for approximately 28 days. For the first few weeks following hatching, the chicks are fed daily by their parents through regurgitation. The young macaws then begin to explore their surroundings and learn how to eat themselves. They are also taught to fly and hunt for food.
Like all birds, glaucous Macaws are highly social creatures. They are active during daylight hours and rest during the night. They will often seek shelter in tree cavities or other suitable nesting sites for the night. They are highly vocal, and their calls can be heard throughout the forest during the day.
While it is believed that the species will be able to recover from its decline in the wild, the bird is facing many threats, including loss of habitat illegal trapping for the pet trade and deforestation. About 20 glaucous macaws are believed to be in the wild. The IUCN has classified the bird as "Critically endangered--possibly extinct."
The glaucous macaw, also known as Lear's Macaw or Blue-throated Hummingbird, is distinguished by its vivid blue feathers. The parrot measures 70 centimeters in length and has a powerful beaks that are capable of cracking open seeds and nuts. This beautiful bird is native to South America, and it can be found in many habitats such as grasslands, forests, dry lowland and wetlands.
This majestic bird is a sign of South American biodiversity. It has a regal look with its slim body, vibrant blue feathers, and a light build. The beak is curved and black, which aids it break open the seeds and nuts that make up a major portion of its diet. It is a great-looking bird, and it's often used in bird shows. It is also popular in captivity where it can live for a long time.
