Glaucous Macaw
The glaucous Macaw is one of the rarest birds in the world. It is Critically Endangered, and may be extinct in the wild.
Many Aviculturalists have reported sightings of this bird, but the most recent was in 1992. The alleged sighting was reported to have occurred in southwestern Paraguay close to the city of Corrientes. The bird was male.
Origin
The Glaucous Macaw is a bird native to South America. It is threatened. This magnificent bird features a distinctive blue feather pattern as well as a powerful beak capable of breaking open tough seeds and nuts. Glaucous macaws form long-term monogamous families and both parents assist in raising the chicks. The chicks are fed regurgitated food during the first few weeks of life before being fed solid food as the chicks develop. Parents are a key part of teaching young macaws to fly and hunt.
The glaucous Macaw is extinct, but rumors about its existence continue to circulate across the globe. 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 would gather their food. The glaucous Macaw is believed to be making a comeback and is usually kept with its larger relative, Lear’s macaw.
In terms of habitat the glaucous macaw can be found in subtropical forests of South America. They are usually located in areas with a lot of palm trees, and they are believed to be extremely adaptable to different types of forested habitats. These beautiful birds are territorial and will defend the nesting and feeding area from intruders.
There have been a number of reports on the glaucous macaw over the years, but they are considered to be not reliable. The most recent wild claim was made by an avicultural friend of Ridgely who claimed to have spotted four Glaucous Macaws in Califomia. This is a ridiculous claim until it is supported by solid evidence. Many experts have concluded that the bird is likely extinct as there are no evidence of it in the last century. However they have always been willing accept a remote chance of its survival. If it does survive, it is extremely unlikely to reach large numbers.
Habitat
The macaw glaucous is an impressive bird, renowned for its huge size and stunning turquoise-blue coloration. Its wings and tail feathers are long, which enhances its fluid and graceful movement. This bird is an emblem of loyalty and love. Its beak, which is primarily black, has a distinctive shape that allows it to crack seeds and nuts. They are a significant portion of its diet.
IUCN has classified the Glaucous Macaw as Critically Endangered. It states that there is only a small population of this bird, and that it is at a the risk of becoming extinct. This species was formerly fairly widespread but now it is found only in northern Argentina as well as 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 small range, even though there was no proof of sightings since 1830. There were specimens collected up until the year 1860 (in Corrientes). The last known living Glaucous Macaw was displayed at the Buenos Aires Zoo in 1936 and is believed to have come from Brazil.
A re-examination of the historical documents 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 forests of riparian along rivers. It was a particular feeder of palm fruits, especially those of the chatay palm (Butia yatay) however, it was also likely to feed on ripe and unripe fruit such as berries, nuts, and vegetable matter. It nestled on slopes and in cliffs, occasionally in tree cavities and laid an average clutch of two eggs.
As with other parrots this bird was social and was likely to be gregarious. It was able to live up to 14.8 years in captivity. It was said to be a reliable breeder that reproduced year after year. Its life expectancy in the wild was 50-80 years. This species was a powerful seed disperser, and could have contributed to the success of the yatay palm in its native habitats.
Feeding
The Glaucous Macaw is one of the most stunning parrots. The presence of this parrot has an influence on the surrounding. This large South American bird is known for its vibrant blue feathers and yellow eyes, and also for its distinctive teardrop-shaped lipped sleeve that covers the lower portion of its beak.
As of the time of writing, little was known of the eating habits and diet of the Glaucous macaw. The first references to the subject I have found are in two works by H.W. Bates' "The Naturalist on the amazons" first published in 1863, and describes his 11-year stay in Brazil. In his later book "As Birds of exotic bird purchase the Brazilian Forests" Bates wrote about the similar experience. Both of these refer to the Hyacinthine Macaw (Anodorhynchus aureolarius), but I have no reason to think that they're not applicable to this species.
It is likely that the Glaucous Macaw was a specialist in the consumption of palm nuts, and also consumed other seeds, fruits and vegetable matter in smaller amounts. The diet of this species is likely to be affected by the clearing of forests by the early colonists for agriculture and cattle ranching as well as the removal of the yatay palm (Butia yatay) from which it may have gotten a lot of its diet.
In the wild in the wild, the Glaucous Macaw was commonly found in subtropical forests that had mountains and savannahs that were surrounded by palm trees, where it nestled in tree cavities and on rocky banks, or in the top of palm fronds. On average two clutches of eggs was laid and incubated by the female.
The young Glaucous Macaws rely on their parents for their care until they fly and fully fledged. Both males and females are extremely committed to their offspring and will constantly hunt for food and protect them from predators.
Unfortunately, the Glaucous macaw is no longer found in its former habitat. The disappearance of this magnificent bird is likely due to trapping that continues for the pet industry and habitat disruption, especially the mass removal of palm yatays, which may have been its primary food source. The Glaucous macaw is classified as Critically Endangered.
Breeding
Glaucous Macaws form monogamous couples. Both parents are involved in raising their young. They breed in the dry season, which is when food is most abundant. Females lay two to three eggs that are incubated by the mother for around 28 days. For the first few weeks following hatching, the chicks are fed by the parents through regurgitation. The young macaws begin to explore and learn to feed themselves. They also learn to fly and hunt for food.
Like all birds, glaucous macaws are highly social creatures. They are active during the day and sleep at night. They often seek refuge in tree cavities or other nesting spots for the night. They are highly vocal, and their calls can be heard throughout the forest during the day.
The species is expected to rebound from the decline, but it is facing numerous threats, including habitat loss and illegal trapping of the bird to sell on the pet market and deforestation. It is believed that there are just 20 glaucous macaws living in the wild. The IUCN has classified the bird as "Critically endangered--possibly extinct."
The glaucous Macaw, sometimes referred to as Lear's Macaw or blue-throated Hummingbird, is distinguished by its vivid blue feathers. It is a large parrot with a length of 70 centimeters, and has a strong beak that is able to break open hard nuts and seeds. This gorgeous bird is native to South America and can be found in a variety of habitats that include grasslands, lowland forests and wetlands.
This magnificent bird is a symbol of South American biodiversity. It has a regal appearance, with its slender body, light weight and vivid blue feathers. Its black and curved beak helps it crack open nuts and seeds, which make up a significant part of its diet. It is a great-looking bird, and it is often used in bird shows. It is also popular in captivity where it can live for a lifetime.
