A variety of aviculturalists have reported sightings of this bird, but the most recent was in 1992. The reported sighting was in the southwest region of Paraguay close to the city of Corrientes. The bird was a male.
Origin
The Glaucous Macaw is a parrot native to South America. It is endangered. This magnificent bird has a distinctive blue feather pattern as well as a powerful beak that is capable of breaking open hard nuts and seeds. Glaucous macaws form long-term monogamous families and both parents assist in raising the chicks. The chicks are fed regurgitated food for the first couple of weeks of life before being fed solid food as they grow. Parents are also responsible for teaching the young macaws to fly and hunt.
The glaucous Macaw is extinct, but rumors about its existence continue to spread all over the world. It is believed that the glaucous macaw was extinct in the 1800s because of the logging industry and cattle grazing in yatay palm (Butia yatay) groves, where these birds typically gathered their food. The Glaucous Macaw is believed have returned, and is often kept with its larger relative, Lear’s macaw.
The glaucous Macaw is found in sub-tropical rainforests in South America. They are most often found in areas with abundant palm trees, and they are known to be highly adaptable to various types of forested habitats. These beautiful birds are territorial and will defend the nesting and feeding areas from intruders.
In the past, there have been many reports about the glaucous Macaw, but they are generally considered 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 completely untrue until it is confirmed by hard evidence. The absence of any credible records of this bird in the last century has been a reason for many experts to conclude that it is likely extinct, but they have always been open to the possibility of survival (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it is able to survive, it is extremely unlikely to make it to huge numbers.
Habitat
The glaucous Macaw is an impressive bird, known for its large size and turquoise-blue coloration. The long tail and wings enhance its graceful and agile moves. This bird is also an emblem of loyalty and love. Its beak is mostly black, and it is distinctive in its shape. It allows it to break open seeds and nuts, which comprise a large part of its diet.
The Glaucous Macaw is considered Critically Endangered by the IUCN which states that it is a small population and is at buy a macaw parrot significant danger of disappearing. This species was formerly relatively widespread, but it is found only in northern Argentina and southern Paraguay, north-eastern Uruguay and Brazil from Parana state southwards. It nestted in cliffs along major rivers.
The Glaucous Macaw was not rare in its limited range, despite the fact that there was no proof of sightings since 1830. Specimens were taken up until the year 1850 (in Corrientes). The last living Glaucous Macaw believed to be from Brazil was displayed in the Buenos Aires Zoo back in 1936.
A reassessment of the historical documents suggests that this species was a very generalist in its preferences for habitat, with a preference for savanna habitat intermingled with palm "islands" and areas of riparian forest along river systems. It was a specialized for the consumption of palm fruits, especially those of the yatay (or chatay) palm (Butia). However, it also ate ripe and unripe fruits as well as berries, nuts and other vegetable matter. It nestled on slopes and in cliffs sometimes in tree cavities and laid an average clutch of two eggs.
Like all parrots, this bird was social and likely to be sociable. It was said that it could live for up to 14.4 years in captivity and was a reliable breeder who reproduced year after. Its life expectancy in the wild was about 50 to 80 years. This species was a powerful seed disperser and could have contributed to the success of the yatay palm within its natural habitats.
Feeding
The Glaucous Macaw (Anodorhynchus glaucus) is one of the most stunning of the species of parrots, and its presence commands an enormous impact on its environment. This large South American bird is known for its vibrant blue feathers and yellow eyes, as well as its distinctive teardrop-shaped lappet that brackets the lower portion of its beak.
Up until recently, very little was known about eating habits and diet of the Glaucous macaw. The first references to the subject I have discovered are in two books by H.W. Bates' "The Naturalist on the amazons", first published in 1863, and describes his 11-year stay in Brazil. Later in his book "As Birds of the Brazilian Forests", he wrote about the same experience. Both of these are about the Hyacinthine Macaw (Anodorhynchus aureolarius), but I have no reason to believe that they are not applicable to this species.
It is probable that the Glaucous Macaw was a particular feeder of palm nuts and also ate other seeds, fruits and vegetable matter in small amounts. The diet of this species was likely affected by the clearing of forests for farming and cattle-ranching by early colonists, as well the removal of yatay (Butia) palms from which it received much of its nutrition.

Unfortunately, the Glaucous macaw has been found in most of its former habitat. The disappearance of this magnificent bird is likely to be due to the continued trapping of birds for the pet industry, as well as habitat disruption, especially the wholesale clearing of palm yatays which may have been its primary food source. The Glaucous macaw is listed under Critically Endangered.
Breeding
Glaucous macaws usually form long-term monogamous couples and both parents play a role in raising the young. They breed during the dry season when the availability of food is at its greatest. The female lays two to three eggs that are incubated by the mother for around 28 days. Once the chicks hatch they are fed by their parents via regurgitation for the first couple of weeks of life. The young macaws then begin to explore their surroundings and begin to learn to eat themselves. They also learn how to fly and hunt for food.
Like all species of birds, glaucous macaws are extremely social creatures. They are active during daylight hours, and rest during the night. During the night, they will often seek refuge in tree cavities or other nesting spots that are suitable. They are extremely vocal and their calls can macaws be pets be heard throughout the forest during the day.
Although it is hoped 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. About 20 glaucous macaws are estimated to be living in the wild. The IUCN has classified the bird as "Critically endangered, possibly extinct."
