Glaucous Macaw
The glaucous macaw is one of the rarest birds on earth. It is considered Critically Endangered and could be extinct in the wild.
The bird has been reported by aviculturists in various countries, but the latest sighting was in 1992. The alleged sighting was reported to have occurred in the southwestern region of Paraguay, near the city of Corrientes. The bird was male.
Origin
The Glaucous macaw is an endangered parrot species that is native to South America. This majestic bird is distinguished by its distinctive blue feather pattern and a strong beak that is capable of cracking open tough seeds and nuts. Glaucous Macaws are monogamous couples and both parents care for the chicks. The chicks are fed regurgitated food in the first few weeks of life and then a variety of solid foods as the chicks develop. Parents are also responsible for teaching the young macaws to fly and hunt.
The glaucous macaw is believed to be extinct in the wild, yet stories of this gorgeous bird's existence persist all over the world. The glaucous Macaw is believed to have been extinct in the 1800s because of cattle grazing on yatay (Butia) palm groves, where the birds gathered their food. The Glaucous Macaw is believed be making a comeback and is usually kept with its larger mate, Lear's macaw.
In terms of habitat, the glaucous macaw can be found in subtropical forests of South America. They are most often located in areas where there are many palm trees. They are also very adaptable to various types of forested environments. These beautiful birds are recognized as being very territorial and will defend their nesting and feeding areas from invaders.
In the past, there have been many reports of the glaucous macaw, but they are generally not considered reliable. The most recent wild claim was made by an avicultural acquaintance of Ridgely who claimed to have spotted four Glaucous Macaws in Califomia. This claim is untrue until it can backed up with evidence. Many experts have concluded that the bird is likely extinct because there are no records in the last century. However, they have always been willing to accept a slim chance of its survival. If it survives it is highly unlikely to make it to large numbers.
Habitat
The Glaucous Macaw is a stunning bird, well-known for its huge size and turquoise-blue coloration. Its long tail and wings accentuate its graceful and agile movements. This bird is also an emblem of loyalty and love. Its beak, which is mostly black, has a distinct shape that allows it to break seeds and nuts. They form a large part its diet.
The Glaucous Macaw is considered Critically Endangered by the IUCN which states that it is a small population and is at high danger of disappearing. The species was once widespread, but is now only found in northern Argentina, south Paraguay and north-eastern Uruguay, as well as Brazil from Parana state to south, where it nests in cliffs along major rivers.
Although there have been no confirmed sightings of this species since 1830, the Glaucous Macaw seemed not to be extremely rare within its comparatively small range; specimens were taken from 1830 to 1860 (in Corrientes). The last living Glaucous Macaw, believed to originate from Brazil, was exhibited in the Buenos Aires Zoo back in 1936.
A reassessment of the historical documents suggests that this species was a rather generalist in its habitat preferences and preferred savanna habitat intermingled with palm "islands" and areas of riparian forest along rivers. It was a particular in the consuming of palm fruit especially those of the yatay (or chatay) palm (Butia). However, it also ate ripe or unripe fruits, nuts, berries, 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, similar to other parrots. It was reported that it could live up to 14.4 years in captivity, and was a reliable breeder who reproduced year after year. In the wild, the lifespan was probably 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 (Anodorhynchus glaucus) is one of the most beautiful of the species of parrots and has a an enormous impact on its environment. This large South American bird is known for its vivid blue feathers and yellow eyes as well as its distinctive teardrop-shaped lappet which adorns the lower portion of its beak.
Until recently very little was known about the feeding habits of the Glaucous Macaw. The first references to the subject I have found are in two publications by H.W. Bates' "The Naturalist on Amazons" which was first published in 1863, describes his 11-year sojourn in Brazil. In his later book "As Birds of the Brazilian Forests" He wrote about the similar experience. Both of these references to the Hyacinthine Macaw (Anodorhynchus aureolarius), but I have no reason to believe that they are not applicable to this species.
The Glaucous macaw is believed to be a specialist feeder, taking only palm nuts as well as small amounts more info of other seeds, fruits and other matter. The diet of this species was likely heavily influenced by the clearing of forests for agriculture and cattle-ranching by early colonists, as well the yatay (Butia) palms from which it received much of its nutrition.
In the wild, it was common to find the Glaucous macaw in savannahs and forests that were subtropical where palm trees were found. It nestled 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 fully full fledged. Both females and males are extremely dedicated to their young and will constantly hunt for food and protect them from predators.
Unfortunately, the Glaucous macaw is no longer present in the majority of its former habitat. The disappearance of the magnificent bird is likely due to trapping that continues for the pet industry and disturbance of habitat, specifically the mass removal of palm yatays that may have been its primary food source. The Glaucous Macaw is listed as Critically Endangered.
Breeding
Glaucous macaws are typically monogamous pairs, with both parents playing a role in raising the young. They breed during the dry season, which is when food is most abundant. The female will lay 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 during the first few weeks of their life. The young macaws begin to explore and to feed themselves. They also learn to fly and hunt for food.
Like all birds, glaucous Macaws are social animals. They are active during daylight hours, and take a break at night. During the night they usually seek refuge inside tree cavities or other nesting areas that are suitable. They are very vocal and their calls can be heard throughout the forest during the day.
While it is hoped that the species will be able to recover from its decline in the wild, the bird is facing numerous threats, including the loss of habitat illegal trapping for the pet trade, and deforestation. It is estimated that there are only about 20 glaucous macaws living in the wild. The IUCN has classified 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 vivid 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 gorgeous bird is native to South America and can be found in diverse habitats, including grasslands, forests, and lowland wetlands.
This magnificent bird is an emblem of South American biodiversity. It has a regal look with its slender body, bright blue feathers, and a light build. Its black and curved beak helps it crack open nuts and seeds, which make up a significant part of its diet. It's a beautiful bird, and it is often featured in shows featuring birds. It is also a favorite in captivity, where it can be kept for a lifetime.
