Glaucous Macaw
The glaucous macaw is considered to be one of the rarest birds on earth. It is considered Critically Endangered and could become extinct in the wild.
Many Aviculturalists have reported sightings of this bird However, the most recent sighting was in 1992. The reported sighting was in southwestern Paraguay close to 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 is distinguished by the blue feather pattern and a powerful beak capable of cracking open nuts and seeds. Glaucous Macaws live in monogamous pairs, and both parents raise the chicks. They feed the chicks a diet of regurgitated food for the first few weeks after birth, and then they begin to eat solid foods as they develop. Parents are also responsible for teaching young macaws to fly and hunt.
The glaucous Macaw is thought to be extinct in the wild, yet rumors of this beautiful bird's existence are still spreading throughout the world. The glaucous Macaw is believed to be extinct by the 1800s because of logging and cattle grazing on yatay (Butia) palm groves, where the birds gathered their food. It is currently believed that the glaucous macaw returned to captivity in the wild, where it is kept alongside its larger cousin Lear's macaw.
In terms of habitat The glaucous macaw is able to be found in subtropical forests of South America. They are usually found in areas that have plenty of palm trees, and they are believed to be extremely adaptable to a variety of forested habitats. These beautiful birds are also known to be extremely territorial and will protect their feeding and nesting areas from invaders.
There have been a lot of reports about the glaucous macaw through the years, but they are considered to be unreliable. The most recent wild claim was made by an avicultural friend of Ridgely who claimed to have seen four Glaucous Macaws in Califomia. This is a completely absurd claim until it can be verified with solid evidence. Many experts have concluded that the bird is likely to be extinct since there are no records from the last century. However, they have always been willing to accept a slim chance of its survival. If it survives, it will be extremely rare to observe large numbers.
Habitat
The glaucous macaw is a striking bird that is renowned for its size and stunning turquoise-blue coloring. Its long tail and wings enhance its graceful and agile movements. This bird is an emblem of love and loyalty. Its beak is predominantly black and has a distinctive shape that allows it to crack open nuts and seeds, which constitute a significant part of its diet.
IUCN has classified the Glaucous Macaw as Critically Endangered. It notes that there is a very small population of this bird, and that it is at a the risk of becoming extinct. The species was once widespread, but is now only found in northern Argentina south Paraguay and north-eastern Uruguay, as well as Brazil and Brazil from Parana state to south, where it resides in cliffs along major rivers.
The Glaucous Macaw was not rare in its small area, even though there was no proof of sightings after 1830. The specimens were taken up until the year 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 preferences for habitat with a preference for the savanna ecosystem, which was interspersed with palm "islands" and bands of riparian forest along river systems. It was a specialized feeder of palm fruit, especially those of the yatay (or chatay) palm (Butia). However it also ate ripe or unripe fruits and berries, nuts, and vegetable matter. It nests on slopes that are steep or in cliffs, and also in tree cavities.
This bird was likely to be gregarious and social, just like other parrots. It was reported that it could live to 14.4 years in captivity, and was a reliable breeder that reproduced year after year. The life expectancy of this species in the wild was about 50 to 80 years. The species was a strong disperser of seeds, and could have contributed to the success of the palm yatay species in its natural habitat.
Feeding

The Glaucous Macaw (Anodorhynchus glaucus) is among the most stunning of the species of parrots and has a a powerful impact in its surroundings. This huge South American parrot is known for its bright blue feathers, yellow eyes and the teardrop-shaped lappet on its lower beak.
Until recently macaw keycaps was known about the diet of the Glaucous Macaw. The earliest detailed references that I have come across are two works by H.W. Bates, "The Naturalist on the Amazons" first published in 1863 about his 11 year stay in Brazil and later in his work "As Birds of the Brazilian Forests". Both of these are about the Hyacinthine Macaw, Anodorhynchus Aureolarius. I have no reason to believe that they don't apply to this species.
It is likely that the Glaucous Macaw was a specialist feeder of palm nuts and also consumed other seeds, fruits, and vegetable matter in smaller amounts. The diet of this species is likely to have been affected by the clearing of forests by early colonists for agriculture and cattle ranching as well as the felling of the yatay palm (Butia yatay) from which it could have gotten its majority of its diet.
In the wild, it was common to find the Glaucous macaw in subtropical forests and savannahs where palm trees were found. It was found in tree cavities or on rocky banks or 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 take care of them until they are fully grown and able to fly. Both the males and females are very committed to their offspring and hunt for food and protect them against predators.
Unfortunately, the Glaucous macaw is no longer present in the majority of its former habitat. The disappearance of the majestic bird is likely to be due to trapping that continues for the pet industry as well as disturbance of habitat, specifically the massive removal of palm yatays that may have been its primary food source. The Glaucous Macaw is classified as Critically Endangered.
Breeding
Glaucous macaws typically form long-term monogamous pairs with both parents taking an active role in the raising of the young. They breed during the dry season when food availability is at its greatest. The female lays a clutch of two to three eggs that are incubated for a period of around 28 days. In the initial few weeks after hatching the chicks are fed by the parents through regurgitation. The young macaws then begin to explore their surroundings and begin to learn to eat themselves. They also learn how to fly and forage.
The glaucous Macaw can be described as a extremely social bird. They are active during the day, but sleep at night. They will often seek shelter in cavities in trees or other suitable nesting sites to sleep. Their calls can be heard in the forest throughout the day.
While it is believed that the species will be able to recover from its decline in the wild, the bird faces many threats, including loss of habitat, illegal trapping for the pet trade and deforestation. It is estimated that there are only about 20 glaucous macaws in the wild. The IUCN classifies the bird as "Critically Endangered--Possibly Extinct."
The glaucous Macaw is known as the Lear's macaw, or the blue-throated hummingbird. It can be distinguished by its bright blue feathers. The parrot is 70 centimeters in length and has a powerful beaks that are capable of slicing open nuts and seeds. This beautiful bird is native to South America, and it can be found in many habitats like grasslands, forests, dry lowland and wetland.
This magnificent bird is a symbol of South American biodiversity. It has a regal look with its slender body, vibrant blue feathers and its light build. Its beak is curved and black, which helps it break open the seeds and nuts which comprise a significant portion of its diet. It is a great-looking bird, and is often seen in bird shows. It is also popular in captivity, where it can live for a lifetime.
