Glaucous Macaw
The glaucous macaw is considered to be one of the rarest birds on earth. It is critically endangered and could even be extinct.
Many Aviculturalists have reported sightings of this bird, but the most recent was in 1992. The alleged sighting was reported to be in the southwest region of Paraguay near the city Corrientes. The bird was a male.
Origin
The Glaucous macaw is a threatened parrot species that is native to South America. This majestic bird is distinguished by a blue feather pattern, and a powerful beak capable of cracking open nuts and seeds. Glaucous Macaws are monogamous pair and both parents tend the chicks. The chicks are fed regular food for the first couple of weeks of life and then a variety of solid foods as the chicks develop. Parents are also responsible for teaching young macaws to fly and hunt.
The glaucous macaw is believed to be extinct in the wild, but rumors of this beautiful bird's existence continue to spread across the globe. The Glaucous Macaw is believed have gone extinct in the 1800s due to cattle grazing on yatay (Butia) palm groves from which the birds gathered their food. The Glaucous Macaw is believed have returned, and is often kept with its larger relative, Lear’s macaw.
The glaucous Macaw can be found in sub-tropical rainforests of South America. They are usually located in areas that have many palm trees. They are also very adaptable to various types of forest habitats. These beautiful birds are also known to be extremely territorial and will protect their nesting and feeding areas from invaders.
In the past, there have been numerous reports about the glaucous Macaw, but they are generally regarded as unreliable. The most recent report of a wild occurrence involves an friend of Ridgely's who claimed to have witnessed four Glaucous macaws in Califomia. This is a ridiculous claim until it is supported with evidence. The lack of any acceptable records of this bird in the last century has caused many experts to think that it's likely extinct, however they have always been willing to accept the possibility of existence (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it survives, it is extremely unlikely to make it to huge numbers.
Habitat
The Glaucous Macaw is a stunning bird, well-known for its huge size and turquoise-blue coloring. The tail and wings are long, which aids in its graceful and agile movements. This bird is an emblem of love and loyalty. Its beak, which is primarily black, is distinctive in its shape that allows it to break seeds and nuts. They are a significant part its diet.
IUCN has classified the Glaucous Macaw as Critically Endangered. It states that there is a small population of the bird and it is at risk of extinction. The species was previously relatively widespread, but it is found only 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 reliable sightings of this species since 1830 The Glaucous Macaw seemed not to be very rare in its relatively limited range; specimens were collected up to 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.
Re-evaluation of the historical documents suggests that this species was very generalist in its preferences for habitat and preferred areas of savanna that were interspersed with palm "islands" and forests of riparian along river systems. It was a specialist in the consuming of palm fruit, especially those of the yatay (or chatay) palm (Butia). However, it also ate ripe and unripe fruits and berries, nuts, and even vegetable matter. It is a nesting place on steep slopes or in cliffs, and also in tree cavities.
Like other parrots, this bird was social and was likely to be sociable. It was believed that it could live up to 14.4 years in captivity and was a reliable breeder who reproduced year after. In the wild, its life expectancy was likely to be between 50 and 80 years. This species was a powerful disperser of seeds and could have contributed towards the success of the palm yatay species in its natural habitat.
Feeding
The Glaucous Macaw (Anodorhynchus glaucus) is one of the most stunning of the parrot species, and its presence commands an immense impact in its environment. This large South American bird is known for its vivid blue feathers and eyes that are yellow, as well as its distinctive teardrop-shaped lappet that brackets the lower portion of its beak.
Until recently very little was known about diet of the Glaucous Macaw. The earliest references to this subject that I have found are two works by H.W. Bates' "The Naturalist on Amazons" which was first published in 1863, describes his 11-year sojourn 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 think that they are not applicable to this species.
The Glaucous macaw is likely be a specialist eater, consuming only palm nuts as well as small amounts of other seeds, fruits and other matter. This species' diet was likely influenced by the clearing of forests for agriculture and cattle-ranching by early colonists, and the removal of yatay (Butia) palms from which it derived a lot of its nutrition.
In the wild it was commonplace to see the Glaucous macaw in savannahs and forests that were subtropical where palm trees were found. It hid in tree cavities, or on rocky banks and palm fronds. On average, a clutch of two eggs was laid and then incubated by the female.
The young Glaucous Macaws rely on their parents for care until they are able to fly and are 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 the magnificent bird is likely to be due to trapping that continues for the pet industry, as well as disturbance to habitat, particularly the mass removal of palm yatays, which may have been its primary food source. The Glaucous macaw is listed as Critically Endangered.
Breeding
Glaucous macaws usually form long-term monogamous pairs, with both parents playing a role in raising the young. They breed during the dry season, when the availability of food is at its greatest. The female lays an egg clutch of between two and three eggs, which are incubated for about 28 days. After hatching, they are fed by their parents through regurgitation for the first few weeks of their life. Macaws are then able exploring and learning to feed themselves. They are also taught to fly and forage.
The glaucous Macaw is extremely social bird. They are active during daylight hours and rest at night. They often seek refuge in cavities in trees or other nesting spots to sleep. They are very vocal and their calls can be heard throughout the forest during the day.
The species is expected to recover from its decline, however it faces many threats including habitat loss, illegal trapping of the bird for the pet market, and deforestation. It is believed that there are less than 20 glaucous macaws living in the wild. The IUCN classifies the bird as "Critically Endangered, possibly extinct."
The glaucous macaw, also known as Lear's Macaw, or the blue-throated Hummingbird is distinguished by its vibrantly blue feathers. Sinatra Macaws for Sale is 70 centimeters long and has a powerful beak capable of breaking open nuts and seeds. This beautiful bird is native to South America, and it can be found in many habitats like forests, dry lowland grasslands, and wetlands.
This magnificent bird is a symbol of South American biodiversity. Its appearance is elegant with its slender body, bright 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 great-looking bird, and it's often used in shows featuring birds. It is also popular in captivity where it can live for a long time.
