Glaucous Macaw
The glaucous Macaw is among the rarest birds in the world. It is critically endangered and could even be extinct.
This bird has been reported by aviculturists across the globe However, the most recent sighting was recorded in 1992. The alleged sighting was reported to be in the southwest of Paraguay near the city Corrientes. The bird was male.
Origin
The Glaucous Macaw is a species of parrot native to South America. It is threatened. 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 monogamous couples and both parents care for the chicks. They feed their chicks regurgitated food for the first couple of weeks after birth, before they begin eating solid foods as they grow. Parents are also responsible for teaching the young macaws to fly and hunt.
The glaucous Macaw has gone extinct, yet rumors of its existence persist across the globe. The glaucous Macaw is believed to have gone 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 to be making a comeback and is often kept along with its larger mate, Lear's macaw.
The glaucous Macaw lives in sub-tropical rainforests in South America. They are usually found in areas with numerous palm trees. They are also very adaptable to various types of forested environments. These beautiful birds can be territorial and will protect the feeding and nesting area from intruders.
There have been a lot of reports about the glaucous macaw throughout the years, but most are considered to be not reliable. The most recent wild claim was made by an avicultural friend of Ridgely who claimed to have spotted four Glaucous Macaws in Califomia. This claim is completely unacceptable until it is confirmed with hard evidence. The absence of any credible evidence of this bird in the past century has led many experts to think that it's likely extinct, yet they have always been open to an extremely remote possibility of its existence (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it is able to survive it is highly unlikely to be seen in large numbers.
Habitat
The macaw glaucous is an impressive bird that is known for its size and stunning turquoise-blue coloration. The tail and wings are long, enhancing its graceful and agile movement. The bird is an emblem of love and loyalty. Its beak is primarily black and is distinctive in its shape. It allows it to open nuts and seeds, which constitute a significant part of its diet.
IUCN has classified the Glaucous Macaw as Critically Endangered. It says that there is a very small population of this bird and it is in risk of extinction. 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 alongside major rivers.
Although there have been no credible sightings of the species since 1830, the Glaucous Macaw seemed not to be a rare species in its comparatively small range; specimens were taken from 1830 to 1850 (in Corrientes). The last living Glaucous Macaw believed to originate from Brazil was seen in the Buenos Aires Zoo back in 1936.
A re-examination of the historical records suggests that this species was very generalist in its habitat preferences and preferred savanna habitat intermingled with palm "islands" and areas of riparian forest along rivers. It was a specialized in the consuming of palm fruit especially those of the yatay (or chatay) palm (Butia). However, it also ate ripe and unripe fruits and berries, nuts, and other vegetable matter. It nestled on slopes and cliffs, sometimes in tree cavities and laid an average clutch of two eggs.
The bird was likely to be gregarious and social, similar to other parrots. It could live for up to 14.8 years in captivity. It was said to be a dependable breeder that reproduced year after year. Its life expectancy in the wild was 50-80 years. The species was a strong disperser of seeds and may have contributed towards the success of the palm yatay species in its natural habitat.
Feeding
The Glaucous Macaw is one of the most stunning parrots. Its presence can have an enormous impact on the environment. This massive South American bird is known for its vivid blue feathers and yellow eyes as well as the distinctive teardrop-shaped lipped sleeve that covers the lower part of its beak.
In the past, little was known of the eating 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, and describes his 11-year sojourn in Brazil. In his later book "As Birds of the Brazilian Forests", he wrote about the same experience. Both are about the Hyacinthine Macaw, Anodorhynchus Aureolarius. I have no reason to think that they could not apply to this species.
It is probable that the Glaucous Macaw was a specialized for the consumption of palm nuts. It also took other seeds, fruits, and vegetable matter in small amounts. The diet of this species was likely heavily influenced by the clearing of forests to cultivate cattle and the cattle-ranching practices of early colonists as well as the removal of yatay (Butia) palms from which it got a large portion 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 or palm fronds. On average two clutches of eggs was laid and incubated by the female.
The young Glaucous Macaws rely on their parents to provide care until they are able to fly and become fully full fledged. Both the males and females are very committed to their offspring and hunt for food and defend them from predators.
Unfortunately the Glaucous macaw has been present in the majority of its former habitat. The disappearance of the magnificent bird is likely due to the continued trapping of birds for the pet industry and disturbance of habitat, specifically the massive clearing of palm yatays which could have been their primary food source. macaw purchase is listed as Critically Endangered.
Mindy catalina macaw macaws usually form long-term monogamous pairs with both parents taking an active role in the raising of the young. They breed in the dry season, which is when food is plentiful. The female lays two to three eggs that are incubated by the mother for approximately 28 days. After hatching, they are fed by their parents via regurgitation for the first couple of weeks of life. The macaws' young begin to explore their surroundings and begin to learn to feed themselves. They also learn to fly and hunt for food.
Like all birds, glaucous macaws are highly social creatures. They are active during the day but are restful at night. They usually seek shelter in cavities in trees or other suitable nesting sites to sleep. They are highly vocal, and their calls can be heard throughout the forest during the day.
The species is expected to recover from the decline, however it is in danger of being wiped out by habitat loss and illegal trapping of the bird for 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 called the Lear's macaw or the blue-throated hummingbird. It is distinguished by its vivid blue feathers. The parrot measures 70 centimeters long and has an impressive beak that is capable of breaking open nuts and seeds. This beautiful bird is native to South America, and it is found in various habitats such as grasslands, forests, dry lowland and wetland.
This majestic bird is a symbol of South American biodiversity. Its appearance is elegant with its slim body, bright blue feathers and its light build. Its beak is curvaceous and black, which aids it break open the nuts and seeds that make up a major portion of its diet. It is a great-looking bird, and is often featured in shows featuring birds. It is also a favourite in the wild, where it can live for a lifetime.
