Glaucous Macaw
The glaucous macaw is considered to be one of the rarest birds on earth. It is considered Critically Endangered and could become extinct in the wild.
Various birdwatchers have reported sightings this bird However, the most recent sighting was in 1992. This alleged sighting was in the southwest region of 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 threatened. This magnificent bird has a unique blue feather pattern and strong beak that is capable of cracking open tough seeds and nuts. Glaucous Macaws form monogamous long-term pairs and both parents tend the chicks. They feed the chicks regurgitated food for the first couple of weeks after birth, and later they begin eating solid food as they grow. Parents are also responsible for teaching 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 are still spreading throughout the world. The Glaucous Macaw is believed have been extinct in the 1800s due to the logging industry and cattle grazing in yatay (Butia) palm groves where the birds would gather their food. The Glaucous Macaw is believed have returned, and is often kept along with its larger relative, Lear’s macaw.
In terms of habitat The glaucous macaw is able to be found in sub-tropical forests of South America. They are usually located in areas with a lot of palm trees, and are known to be highly adaptable to various types of forested habitats. These beautiful birds are territorial and defend the feeding and nesting area from intruders.
There have been a number of reports on the glaucous macaw over the years, but most are considered to be not reliable. The most recent report of a wild incident is an avicultural acquaintance of Ridgely's who claimed to have observed four Glaucous macaws in Califomia. This claim is completely unacceptable until it is verified with hard evidence. Many experts have concluded that the bird is likely extinct as there are no records from the last century. However they have always been willing to accept a small chance of its survival. If it is able to survive it will be extremely rare to witness large numbers.
Habitat
The glaucous macaw is a striking bird, renowned for its huge size and striking turquoise-blue coloration. Its long tail and wings enhance its graceful and agile movements. This bird is an emblem of love and loyalty. Its beak, which is mostly black, has a distinctive shape that allows it to crack seeds and nuts. These are a large portion of its diet.
The Glaucous Macaw is considered Critically Endangered by the IUCN, which notes that it is a small population and is at high danger of disappearing. The species was once relatively widespread, but it is found only in northern Argentina as well as southern Paraguay, north-eastern Uruguay and Brazil from Parana state southwards, where it was a nesting place in cliffs along major rivers.
Although there have been no credible sightings of the species since 1830 however, the Glaucous Macaw seemed not to be a rare species in its comparatively small range; specimens were collected up to 1850 (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.
A reassessment of the historical documents suggests that this species was very generalist in its habitat preferences, with a preference for savanna habitat intermingled with palm "islands" and forests of riparian along rivers. It was a particular eater of palm fruits, specifically those of the chatay palm (Butia yatay) but it could also feed on ripe and unripe fruits such as berries, nuts, and vegetables. It is a nesting place on steep slopes, in cliffs and sometimes in tree cavities.
As with other parrots this bird was social and was probably gregarious. It was able to live up to 14.8 years in captivity. It was said to be a reliable breeder that reproduced year after year. Its life expectancy in the wild was perhaps between 50 and 80 years. This species was a powerful disperser of seeds and may be a factor in the success of the palm yatay in its natural habitats.
Feeding
The Glaucous Macaw is one of the most stunning parrots. The presence of this parrot has an enormous impact on the environment. This large South American bird is known for its vibrant blue feathers and yellow eyes, as well as its distinctive teardrop-shaped lappet which adorns the lower part of its beak.
In the past, little was known about feeding 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 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 similar experience. Both are about the Hyacinthine Macaw Anodorhynchus Aureolarius. I have no reason to think that they could not apply to this species.
The Glaucous macaw is believed to have been a specialist feeder, taking only palm nuts as well as tiny amounts of other fruits, seeds and vegetable matter. The diet of this species was likely influenced by the clearing of forests to cultivate cattle and the cattle-ranching practices of early colonists, and the yatay (Butia) palms from which it received much of its nutritional value.
In the wild the Glaucous Macaw was commonly found in subtropical forests that had the savannahs and cliffs surrounded by palm trees where it nested in tree cavities and on rocky banks, or in the palm fronds' top. On average two eggs were laid in a clutch. eggs was laid and then incubated by the female.
The young Glaucous Macaws are altricial, meaning they depend on their parents to look after them until they become fully grown and able to fly. Both the male and female are extremely committed to their young and will continuously hunt for food and defend them from predators.
Unfortunately, the Glaucous Macaw has been eradicated from most of its previous range. The disappearance of the magnificent bird is likely due to trapping that continues for the pet industry as well as disturbance to habitat, particularly the massive removal of palm yatays that could have been their primary food source. The Glaucous Macaw is listed as Critically Endangered.
Breeding
Glaucous Macaws form monogamous couples. Both parents are involved in the raising of their young. They breed during the dry season when food availability is at its highest. The female lays a clutch of two to three eggs that are incubated for about 28 days. When the chicks are born, they are fed by their parents via regurgitation for the first couple of weeks of their life. Then the young macaws begin to explore their surroundings and learn how to eat themselves. They also learn how buy macaw to fly and hunt for food.
The glaucous Macaw can be described as a highly social bird. They are active during daylight hours and rest during the night. They will often seek shelter in tree cavities or other nesting spots to sleep. They are highly 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 less than 20 glaucous macaws living in the wild. The IUCN classifies the bird as "Critically Endangered - possibly Extinct."
The glaucous macaw is known as the Lear's macaw or blue-throated hummingbird. It can be distinguished by its vibrant blue feathers. It is a large parrot, measuring 70 centimeters in length, and has a strong beak that is able to break open tough nuts and seeds. This gorgeous bird is native to South America, and it can be found in many habitats such as forests, dry lowland grasslands, and wetlands.
This majestic bird is a symbol of South American biodiversity. It has a regal look with its slim body, bright blue feathers and its light build. The beak is curved and black, which helps it open the nuts and seeds that comprise a large portion of its diet. It is a beautiful bird and is often used in bird shows. It is also a favorite in captivity, where it can be kept for a lifetime.
