Glaucous Macaw
The glaucous macaw is considered to be one of the world's rarest birds. It is considered Critically Endangered, and may be extinct in the wild.
Many aviculturalists have reported sightings of this bird However, the most recent sighting was in 1992. The alleged sighting was reported to be in southwest Paraguay near the city Corrientes. The bird was male.
Origin
The Glaucous Macaw is a bird native to South America. It is endangered. This magnificent bird is characterized by a blue feather pattern, and a strong beak that can break open seeds and nuts. Glaucous macaws have been known to form long-term monogamous families and both parents help raise the chicks. The chicks are fed regurgitated food during the first few weeks of life before being fed solid food as they grow. Parents also play a vital role in teaching the young macaws how to fly and forage.
The glaucous Macaw has gone extinct, but rumors about its existence continue to circulate around the world. The glaucous Macaw is believed to have gone extinct in the 1800s because of cattle grazing on yatay (Butia) palm groves from which the birds would gather their food. The glaucous Macaw is believed to have made a comeback, and is usually kept with its larger mate, Lear's macaw.
The glaucous Macaw is found in sub-tropical rainforests in South America. They are typically found in areas with abundant palm trees, and are believed to be extremely adaptable to a variety of forested habitats. These beautiful birds are known to be extremely territorial and will protect their feeding and nesting areas from trespassers.
Over the years there have been numerous reports of the glaucous macaw, but they are generally considered unreliable. The most recent wild claim was reported by an avicultural friend of Ridgely who claimed to have spotted four Glaucous Macaws in Califomia. This claim is completely unacceptable 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 in the last century. However, they have always been willing to accept a small chance of its survival. If it is able to survive it is highly unlikely to reach huge numbers.
Habitat
The macaw with the glaucous is a striking bird that is known for its huge size and striking turquoise-blue coloring. The long tail and wings accentuate its graceful and agile movements. This bird is a symbol of loyalty and love. Its beak is predominantly black, and it is distinctive in its shape. It allows it to break open seeds and nuts which comprise a large portion of its diet.
IUCN has classified the Glaucous Macaw as Critically Endangered. It notes that there is only a tiny population of this bird and it is in high-risk of extinction. This species was formerly quite widespread, but today it is found in northern Argentina, southern Paraguay, north-eastern Uruguay and Brazil from Parana state southwards where it was a nesting place in cliffs along major rivers.
While there have been no credible sightings of the species since 1830 however, the Glaucous Macaw seemed not to be a rare species in its comparatively small range; specimens were collected up to 1850 (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.
severe macaw -evaluation of the historical records suggests that this species was a more generalist in its preferences for habitat and preferred areas of savanna that were interspersed with palm "islands" and forests of riparian along rivers. It was a specific food source for palm fruits, especially those of the chatay or yatay palm (Butia yatay), but it could also consume ripe and unripe fruit as well as berries, nuts and vegetable matter. It is a nesting place on steep slopes, in cliffs and sometimes in tree cavities.
The bird was likely to be gregarious and social, like other parrots. It could live up to 14.8 years in captivity and was said to be a reliable breeder, reproducing year after year. The life expectancy of this species in the wild was 50-80 years. This species was a potent seed disperser and may 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 a strong influence on the surrounding. This huge South American bird is known for its vivid blue feathers and yellow eyes, as well as its distinctive teardrop-shaped lipped sleeve that covers the lower portion of its beak.
Up until recently, very little was known of the feeding 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" which was first published in 1863, which describes his 11-year stay in Brazil. Later in his book "As Birds of the Brazilian Forests", he wrote about the similar experience. Both of them are about the Hyacinthine Macaw Anodorhynchus Aureolarius. I have no reason to think that they could not apply to this species.
The Glaucous macaw is believed to be a specialist eater, consuming only palm nuts as well as tiny amounts of other seeds, fruits and other matter. This species' diet was likely affected by the clearing of forests for farming and cattle-ranching by early colonists, as well the felling of yatay (Butia) palms from which it derived a lot of its nutrition.
In the wild the Glaucous Macaw was often found in subtropical forests with mountains and savannahs that were surrounded by palm trees, where it nested in tree cavities, on rocky banks or the top of palm fronds. The female incubates and lays two eggs per.
The young Glaucous Macaws rely on their parents for care until they can fly and fully grown. Both males and females are extremely committed to their offspring and will constantly hunt for food and defend them from predators.
Unfortunately, the Glaucous Macaw has been eradicated from most of its former range. The disappearance of this majestic bird is likely due to the continuing trapping of pets for the pet trade as well as disturbance of habitat, especially the mass removal of yatay palms which it could have gotten its primary food source. The Glaucous macaw is classified as Critically Endangered.
Breeding
Glaucous Macaws are monogamous, long-term pairs. Both parents are involved in raising their children. They breed during the dry season, when food availability is at its highest. The female lays a clutch of two to three eggs, which are incubated for about 28 days. When the chicks are born, they are fed by their parents via regurgitation during the first few weeks of their life. The young macaws begin exploring and learning to feed themselves. They are also taught how to fly and hunt for food.
The glaucous Macaw can be described as a extremely social bird. They are active during the day and spend their nights resting. They will often seek shelter in tree cavities or other nesting spots for the night. Their calls can be heard in the forest throughout the day.
The species is expected to recover from the decline, however it faces many threats including habitat loss illegal trapping of the bird for pet trade, and deforestation. It is believed that there are only about 20 glaucous macaws in the wild. The IUCN classifies 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 measuring 70 centimeters long and has a sturdy beak that can crack open hard nuts and seeds. The beautiful bird is native to South America and can be found in a variety of habitats such as grasslands, forests, and lowland wetlands.
This majestic bird is a symbol of South American biodiversity. It has a regal look with its slim body, vibrant blue feathers and its light build. The black and curly beak allows it to break open seeds and nuts, which make up a significant part of its diet. It is a stunning bird, and is frequently featured in birds shows. It is also a favourite in captivity, where it can remain for a long time.
