Glaucous Macaw
The glaucous Macaw is among the rarest birds in the world. It is in danger of disappearing and could be extinct.
Many birdwatchers have reported sightings this bird However, the most recent sighting was in 1992. The reported sighting was in the southwestern region of Paraguay, near the city of Corrientes. The bird was male.
Origin
The Glaucous macaw is an endangered parrot species native to South America. This magnificent bird features a distinctive blue feather pattern as well as a powerful beak that is capable of cracking open tough nuts and seeds. Glaucous macaws are known to form long-term monogamous pairs and both parents are involved in the raising of the chicks. They feed the chicks regurgitated food for the first couple of weeks after birth, and later they begin to eat solid foods as they grow. The parents also play a crucial role in teaching young macaws to fly and forage.
The glaucous Macaw has gone extinct, yet rumors of its existence persist all over the world. The glaucous Macaw is believed to have gone extinct in the 1800s because of logging and cattle grazing on yatay (Butia) palm groves, where the birds gathered their food. The Glaucous Macaw is believed have returned, and is usually kept with its larger mate, Lear's macaw.
In terms of habitat, the glaucous macaw can be found in sub-tropical forests of South America. They are most often found in areas that have plenty of palm trees, and they are thought to be extremely adaptable to a variety of forested habitats. These beautiful birds are also recognized as being very territorial and will protect their nesting and feeding areas from invaders.
Over the years there have been many reports on the glaucous Macaw However, they are generally regarded as unreliable. The most recent wild claim was made by an avicultural acquaintance of Ridgely who claimed to have spotted four Glaucous Macaws in Califomia. This is completely untrue until it can be verified with hard 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 slim chance of its survival. If it is able to survive, it is extremely unlikely to reach huge numbers.
Habitat
The Glaucous Macaw is a stunning bird, known for its size and turquoise-blue coloring. The long tail and wings highlight its graceful and agile moves. This bird is an emblem of love and loyalty. Its beak is mostly black and has a distinctive shape that allows it to break open nuts and seeds, which comprise a large portion of its diet.
IUCN has classified the Glaucous Macaw as Critically Endangered. It says that there is a small population of this bird and it is at high-risk of extinction. The species was previously quite widespread, but today it is found in northern Argentina as well as southern Paraguay and north-eastern Uruguay and Brazil from Parana state southwards. It nestted in cliffs along major rivers.
While there have been no confirmed sightings of this species since 1830 The Glaucous Macaw seemed not to be a rare species in its comparatively small range; specimens were taken up to 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.
The reassessment suggests that the species is a generalist, preferring areas of savanna that are interspersed with palm "islands" and riparian forest bands along river systems. It was a specialist for the consumption of palm fruits particularly those of the yatay (or chatay) palm (Butia). However, it also ate ripe or unripe fruits, nuts, berries, and other vegetable matter. It is a nesting place on steep slopes or in cliffs, and also in tree cavities.
The bird was likely to be gregarious and social, just like other parrots. It was believed that it could live to 14.4 years in captivity and was a reliable breeder that reproduced year after. The lifespan of the species in the wild was between 50 and 80 years. This species was a formidable 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. Its presence can have a strong impact on the environment. This massive South American bird is known for its vibrant blue feathers and eyes that are yellow, as well as its distinctive teardrop-shaped lappet that brackets the lower part of its beak.
Until recently very little was known about the feeding habits of the Glaucous Macaw. The earliest detailed references that I have located are two works by H.W. Bates' "The Naturalist on Amazons", first published in 1863, 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 these are about the Hyacinthine Macaw (Anodorhynchus aureolarius) however I see no reason to think that they're not applicable to this species.
It is probable that the Glaucous Macaw was a specialist for the consumption of palm nuts. It also consumed other seeds, fruits and vegetable matter in smaller amounts. The diet of this species is likely to be influenced by the clearance of forests by the early colonists to cultivate and cattle ranching and the removal of the yatay palm (Butia yatay) from which it could have gotten its majority of its nutrition.
In the wild, it was common to see the Glaucous macaw in subtropical forests and savannahs 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 are altricial, meaning they depend on their parents to care for them until they are fully fledged and can fly. Both the males and females are dedicated to their offspring, and hunt for food and protect them against predators.
Unfortunately unfortunately, the Glaucous macaw isn't found in most of its former habitat. The disappearance of this magnificent bird is probably due to the ongoing trapping of pets for the pet trade, as well as habitat disturbance, particularly the wholesale removal of yatay palms where it could have gotten its primary food source. The Glaucous macaw is listed under Critically Endangered.
Breeding
Glaucous macaws are typically monogamous pairs and both parents play a role in raising the young. Melody blue spix macaw breed during the dry season, when food is plentiful. Females lay an egg clutch of between two and three eggs, which are incubated for a period of around 28 days. For the first few weeks after hatching the chicks are fed by the parents through regurgitation. The young macaws begin to explore and to feed themselves. They also learn to fly and forage.
The glaucous Macaw is a highly social bird. They are active during the day and are restful at night. They often seek refuge in tree cavities or other nesting spots to sleep. They are extremely 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 to sell on the pet market and deforestation. About 20 glaucous macaws are believed to be in the wild. The IUCN classifies the bird as "Critically Endangered--Possibly Extinct."
The glaucous Macaw is sometimes referred to as Lear's Macaw, or the blue-throated Hummingbird, is distinguished by its vibrantly blue feathers. It is a large parrot with a length of 70 centimeters and features a robust beak that is able to break open hard nuts and seeds. This beautiful bird is native to South America, and it can be found in many habitats, including grasslands, forests, dry lowland and wetland.
This magnificent bird is a symbol of South American biodiversity. Its elegant appearance is reflected with its slim body, vibrant blue feathers, and a light build. The black and curly beak allows it to break open seeds and nuts, which comprise a significant portion of its diet. It is a stunning bird, and is frequently featured in bird shows. It is also popular in captivity where it can live for a lifetime.
