Glaucous Macaw
The glaucous Macaw is one the rarest birds in the world. It is in serious danger and could be extinct.
Various aviculturalists have reported sightings of this bird however the most recent sighting was in 1992. This alleged sighting was in the southwest of Paraguay close to the city of Corrientes. The bird was male.
Origin
The Glaucous macaw is an endangered parrot species native to South America. This majestic bird is distinguished by blue feathers, and a strong beak that is capable of breaking open nuts and seeds. Glaucous macaws form long-term monogamous couples and both parents help raise the chicks. They feed their chicks regurgitated food for the first couple of weeks after birth, and later they begin to eat solid foods as they grow. Parents are also responsible for teaching the young macaws to fly and hunt.
The glaucous Macaw is thought to be extinct in the wild, however reports of this beautiful bird's existence continue to spread across the globe. 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 would gather their food. The Glaucous Macaw is believed have made a comeback, and is often kept with its larger relative, Lear’s macaw.
The glaucous Macaw can be found in subtropical rainforests of South America. They are usually found in areas where there are numerous palm trees. Paisley hyacinth macaw for sale are also known to be extremely adaptable to different types of forest environments. These beautiful birds are also known to be very territorial and will protect their feeding and nesting areas from intruders.
Over the years there have been numerous reports of the glaucous macaw However, they are generally regarded as unreliable. 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 completely absurd claim until it can be verified with hard evidence. Many experts have concluded that this bird is likely to be extinct since there are no records from the last century. However they have been willing accept a remote chance of its survival. If it is able to survive it is highly unlikely to make it to large numbers.
Habitat
The glaucous Macaw is an impressive bird, well-known for its size and turquoise-blue coloration. The long tail and wings highlight its graceful and agile movement. The bird is also an emblem of loyalty and love. Its beak, which is primarily black, has a distinct shape that allows it crack nuts and seeds. They form a large part its diet.
IUCN has classified the Glaucous Macaw as Critically Endangered. It says that there is a very tiny population of this bird and it is in the risk of becoming extinct. This 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 is nestled in cliffs that run alongside 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 collected from 1830 to 1850 (in Corrientes). The last known living Glaucous Macaw was displayed at the Buenos Aires Zoo in 1936 and is believed to be from Brazil.
Re-evaluation of the historical records suggests that this species was a very generalist in its habitat preferences and preferred the savanna ecosystem, which was interspersed with palm "islands" and areas of riparian forest along rivers. It was a particular for the consumption of palm fruits particularly those of the yatay (or chatay) palm (Butia). However, it also ate ripe or unripe fruits as well as berries, nuts and even vegetable matter. It nests on steep slopes or in cliffs, and also in tree cavities.
This bird was likely to be gregarious and social, just like other parrots. It could live for up to 14.8 years in captivity and was believed to be a reliable breeder, reproducing year after year. Its life expectancy in the wild was between 50 and 80 years. macaw parrot cost was a powerful seed disperser, and could have contributed to the success of the yatay palm within its natural habitats.
Feeding
The Glaucous Macaw is one of the most stunning parrots. Its presence has an enormous influence on the surrounding. This huge South American parrot is known for its bright blue feathers, yellow eyes, and the teardrop-shaped lipped on the lower part its beak.
As of the time of writing, little was known about the food habits and diet of the Glaucous macaw. The earliest references to this subject that I have located are two works by H.W. Bates, "The Naturalist on the Amazons" first published in 1863 on his 11 year sojourn in Brazil and later in his work "As Birds of the Brazilian Forests". Both are about the Hyacinthine Macaw, Anodorhynchus Aureolarius. There is no reason to believe that they do not apply to this species.
The Glaucous macaw is likely to be a specialized eater, consuming only palm nuts as well as small amounts of other seeds, fruits and vegetable matter. The diet of this species is likely to be affected by the clearing 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 a lot of its diet.
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 nested in tree cavities and on rocky banks or the palm fronds' top. Females incubate and lay two eggs per.
The young Glaucous Macaws are altricial, meaning they rely on their parents to care for them until they are fully fledged and can fly. Both males and females are extremely dedicated to their offspring and constantly hunt for food and defend them from predators.
Unfortunately, the Glaucous macaw is no longer found in its former habitat. The disappearance of this magnificent bird is most likely due to the ongoing trapping for the pet trade, as well as disturbance to habitat, specifically the wholesale clearing of yatay palms from where it could have gotten its main food supply. The Glaucous Macaw is classified as Critically Endangered.
Breeding
Glaucous Macaws are monogamous, long-term pairs. Both parents are involved in the raising of their young. They breed during the dry season when the availability of food is at its highest. The female lays up to three eggs, which are incubated by the mother for around 28 days. Once the chicks hatch, they are fed by their parents through regurgitation during the first few weeks of life. Then the young macaws begin to explore their surroundings and learn to eat themselves. They also learn how to fly and forage.
The glaucous Macaw is very social bird. They are active during the day but are restful at night. At night they usually seek shelter inside tree cavities or other nesting spots that are suitable. Their calls can be heard in the forest throughout the day.
While it is hoped that the species will recover from its decline in the wild, the bird is facing numerous threats, such as the loss of habitat and illegal trapping for pet trade, and deforestation. There are only about 20 glaucous Macaws that are believed to exist in the wild. The IUCN classifies the bird as "Critically Endangered - possibly Extinct."
The glaucous Macaw is called the Lear's macaw or blue-throated hummingbird. It can be distinguished by its vivid blue feathers. The parrot is 70 centimeters in length and has a powerful beaks that are capable of breaking open nuts and seeds. This gorgeous bird is native to South America, and it can be found in many habitats like grasslands, forests, dry lowland and wetlands.
This majestic bird is a sign of South American biodiversity. Its appearance is elegant with its slender body, vibrant blue feathers and its light build. Its beak is curved and black, which aids it break open the nuts and seeds that comprise a large portion of its diet. It is a stunning bird that is often seen in bird shows. It is also popular in captivity, where it can live for a long time.
