Glaucous Macaw
The glaucous Macaw can be described as one of the rarest birds in the world. It is critically endangered and may even be extinct.
Many birdwatchers have reported sightings this bird, but the most recent was in 1992. The alleged sighting was reported to have occurred in southwestern Paraguay close to the city of Corrientes. The bird was male.
Origin
The Glaucous Macaw is a species of parrot native to South America. It is endangered. This magnificent bird has a distinctive blue feather pattern and a powerful beak capable of cracking open tough seeds and nuts. Glaucous macaws form long-term monogamous families and both parents are involved in the raising of the chicks. The chicks are fed a diet of regurgitated food for the first couple of weeks of their lives before being fed solid food as the chicks develop. 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 rumors of this beautiful bird's existence continue to spread throughout the world. The Glaucous Macaw is believed have been extinct in the 1800s due to logging and cattle grazing on yatay (Butia) palm groves from which the birds would gather their food. It is currently believed that the glaucous macaw has made a comeback in captivity, where it is often raised alongside its larger relative Lear's macaw.
In terms of habitat, the glaucous macaw can be found in sub-tropical forests of South America. They are usually found in areas that have plenty of palm trees, and they are believed to be extremely adaptable to a variety of forested habitats. These beautiful birds are also known to be very territorial and will protect their feeding and nesting areas from intruders.
There have been a lot of reports about the glaucous macaw through the years, but many are considered to be not reliable. The most recent wild claim was reported by an avicultural friend of Ridgely who claimed to have seen four Glaucous Macaws in Califomia. This is a ridiculous claim until it is substantiated with hard evidence. The lack of any acceptable records of this bird in the past century has caused many experts to believe that it is extinct, however they have always been willing to accept an extremely remote possibility of its existence (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it is able to survive, it will be extremely rare to see large numbers.
Habitat
The glaucous macaw is a striking bird that is renowned for its huge size and striking turquoise-blue coloration. Its wings and tail feathers are long, enhancing its graceful and agile movement. The bird is a symbol of loyalty and love. Its beak is predominantly black and has a unique shape that allows it to crack open nuts and seeds, which make up a large portion of 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. This species was formerly fairly widespread but now it is found only in northern Argentina and southern Paraguay, north-eastern Uruguay and Brazil from Parana state southwards. It was a nesting place in cliffs along major rivers.
The Glaucous Macaw was not rare in its limited range, even though there were no reliable sightings since 1830. There were specimens collected until the year 1860 (in Corrientes). The last living Glaucous Macaw believed to be from Brazil was displayed in the Buenos Aires Zoo back in 1936.
A reassessment of the historical records suggests that this species was more generalist in its habitat preferences, with a preference for savanna habitat intermingled with palm "islands" and areas of riparian forest along rivers. It was a particular in the consuming of palm fruit 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 is a nesting place on steep slopes, in cliffs and sometimes in tree cavities.
Like all parrots, this bird was social and likely to be sociable. It could live up to 14.8 years in captivity and was said to be a reliable breeder that reproduced year after year. Its life expectancy in the wild was between 50 and 80 years. This species was a powerful 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 beautiful parrots. The presence of this parrot has a strong impact on its environment. This large South American bird is known for its vibrant blue feathers and yellow eyes and also for its distinctive teardrop-shaped lappet which adorns the lower portion of its beak.
In the past, little was known about eating habits and diet of the Glaucous macaw. The earliest detailed references that I have come across are two works by H.W. Bates, "The Naturalist on the Amazons" first published in 1863 about his 11 year sojourn in Brazil and later in his book "As Birds of the Brazilian Forests". Both of these are about the Hyacinthine Macaw Anodorhynchus Aureolarius. There is no reason to believe that they do not apply to this species.
It is probable that the Glaucous Macaw was a particular for the consumption of palm nuts. It also took other seeds, fruits, and vegetable matter in small amounts. The diet of this species is likely to be influenced by the clearance of forests by early colonists for agriculture and cattle ranching as well as the removal of the yatay palm (Butia yatay) from which it could have received much of its nutrition.
In the wild, the Glaucous Macaw was often found in subtropical forests that had cliffs and savannahs with palm trees, where it nestled in tree cavities, on rocky banks or in the top of palm fronds. On average two eggs were laid in a clutch. eggs was laid and then incubated by the female.
The young Glaucous Macaws are altricial, which means they depend on their parents to take care of them until they become fully grown and fly. Both the male and female are extremely dedicated to their offspring and will tirelessly hunt for food and shield them from predators.
Unfortunately, the Glaucous macaw isn't found in its former habitat. The disappearance of this majestic bird is probably due to the ongoing trapping for the pet trade as well as disturbance to habitat, specifically the massive removal of yatay palms which it could have gotten its main food supply. The Glaucous macaw is listed as Critically Endangered.
Breeding
Glaucous Macaws form monogamous pairs. Both parents are involved in the raising of their children. They breed in the dry season, when food is plentiful. The female lays two to three eggs which are incubated by the mother for around 28 days. In the initial few weeks after hatching the chicks are fed by the parents via regurgitation. The young macaws begin exploring and learning to feed themselves. They are also taught how to fly and forage.
Like all birds, glaucous macaws are highly social creatures. They are active during daylight hours and take a break at night. They will often seek shelter in cavities in trees or other suitable nesting sites for the night. They are highly vocal, and their calls can be heard throughout the forest during the day.
The species is expected to rebound from the decline, but it is facing numerous threats, including habitat loss illegal trapping of the bird for the pet market, and deforestation. Only about 20 glaucous Macaws are believed to exist in the wild. The IUCN has classified the bird as "Critically endangered--possibly extinct."
The glaucous macaw is called the Lear's macaw or the blue-throated hummingbird. It can be distinguished by its bright blue feathers. It is here a large parrot, with a length of 70 centimeters, and has a strong beak that is able to break open seeds and nuts that are tough to break. This beautiful bird is native to South America, and it is found in various habitats like forests, dry lowland grasslands and wetland.
This magnificent bird is a symbol of South American biodiversity. It has a regal appearance with its slim body, light weight and vivid blue feathers. The black and curly beak allows it to break open nuts and seeds, which make up a significant part of its diet. It is a stunning bird, and is frequently featured in birds shows. It is also popular in captivity where it can live a lifetime.
