Glaucous Macaw
The glaucous Macaw is one the rarest birds in the world. It is in danger of disappearing and could be extinct.
A variety of Aviculturalists have reported sightings of this bird, but the most recent was in 1992. The reported sighting was in the southwestern region of Paraguay close to the city of Corrientes. The bird was a male.
Origin
The Glaucous Macaw is a bird native to South America. It is threatened. This majestic bird is distinguished by its distinctive blue feather pattern as well as a strong beak that is capable of breaking open tough seeds and nuts. Glaucous Macaws live in monogamous pair, and both parents raise the chicks. The chicks are fed regurgitated food during the first few weeks of life and then a variety of solid foods as the chicks develop. Parents are also responsible for teaching young macaws to fly and hunt.
The glaucous macaw is considered to be extinct in the wild, but reports of this beautiful bird's existence continue to spread all over the world. The glaucous Macaw is believed to have gone extinct in the 1800s due to cattle grazing on yatay (Butia) palm groves, where the birds would gather their food. The glaucous Macaw is believed to have returned, and is usually kept with its larger relative, Lear’s macaw.
The glaucous Macaw lives in sub-tropical rainforests of South America. They are typically located in areas where there are many palm trees. They are also very adaptable to various types of forested environments. These beautiful birds are known to be very territorial and will defend their feeding and nesting areas from trespassers.
In the past, there have been a variety of reports about the glaucous Macaw However, they are generally considered 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 claim is unacceptable until it is substantiated with hard evidence. The lack of any acceptable evidence of this bird in the last century has been a reason for many experts to conclude that it is likely extinct, but they have always been open to the possibility of survival (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it does survive it is highly unlikely to be seen in huge numbers.
Habitat
The macaw glaucous is an impressive bird that is known for its huge size and striking turquoise-blue coloration. The long tail and wings accentuate its graceful and agile moves. The bird is also an emblem of love and loyalty. Its beak is predominantly black, and it has a unique shape that allows it to crack open nuts and seeds, which comprise a large part of its diet.
IUCN has classified the Glaucous Macaw as Critically Endangered. It states that there is only a small population of the bird and it is at high-risk of extinction. This species was formerly relatively widespread, but 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 small range, even though there was no proof of sightings after 1830. There were specimens collected until 1850 (in Corrientes). The last living Glaucous Macaw, believed to originate from Brazil, was exhibited in the Buenos Aires Zoo back in 1936.
Reassessment suggests that this species is a generalist, preferring the savanna habitat, which is which is surrounded by palm "islands" and bands of riparian forests along river systems. It was a particular food source for palm fruits, particularly those of the chatay or yatay palm (Butia yatay) however, it could also feed on ripe and unripe fruits, nuts, berries and vegetables. It is a nesting place on steep slopes, in cliffs and sometimes in tree cavities.
This bird was likely to be gregarious and social, similar to other parrots. It could live up to 14.8 years in captivity. It was said to be a reliable breeder, reproducing year after year. The lifespan of the species in the wild was perhaps about 50 to 80 years. This species was a powerful seed disperser and may have contributed to the success of the yatay palm within its natural habitats.
Feeding
The Glaucous Macaw (Anodorhynchus glaucus) is one of the most stunning of the species of parrots, and its presence commands an immense impact in its surroundings. This large South American parrot is known for its vibrant blue feathers, yellow eyes and the teardrop-shaped lappet on the lower part its beak.
In the past, little was known of the food habits and diet of the Glaucous macaw. The earliest detailed references that I have located are two works by H.W. Bates' "The Naturalist on Amazons", first published in 1863, which describes his 11-year stay in Brazil. Later, in his book "As Birds of the Brazilian Forests" He wrote about the same experience. Both are about the Hyacinthine Macaw Anodorhynchus Aureolarius. www.buy-macaw.com There is no reason to believe that they don't apply to this species.
The Glaucous macaw is likely have been a specialist feeder, taking only palm nuts as well as small amounts of other seeds, fruits and other matter. The diet of this species is likely to have been affected by the clearing of forests by the early colonists to cultivate and cattle ranching and the felling of the yatay palm (Butia yatay) from which it could have received much of its nutrition.
In the wild, it was common to see the Glaucous macaw in subtropical forests and savannahs in which palm trees were present. It was found in tree cavities, or on rocky banks and palm fronds. On average two eggs were laid in a clutch. eggs was laid and incubated by the female.
The young Glaucous Macaws rely on their parents to provide care until they can fly and are fully grown. Both males and females are dedicated to their offspring, and will hunt for food and defend them against predators.
Unfortunately the Glaucous Macaw has been eliminated from most of its former range. The disappearance of this magnificent bird is likely to be due to the continued trapping of birds 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 typically 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 the food supply is at its highest. The female will lay two to three eggs that are incubated by the mother for approximately 28 days. When the chicks are born, they are fed by their parents through regurgitation during the first few weeks of their life. The young macaws then begin to explore their surroundings and begin to learn to feed themselves. They also learn how to fly and hunt for food.
The glaucous Macaw is extremely social bird. They are active during daylight hours, and take a break at night. During the night they usually seek refuge in tree cavities or other nesting areas that are suitable. Their calls can be heard in the forest throughout the day.
While it is believed that the species will be able to recover from its decline in the wild, the bird faces numerous threats, including the loss of habitat and illegal trapping for pet trade and deforestation. It is believed that there are less than 20 glaucous macaws living in the wild. The IUCN has classified the bird as "Critically endangered--possibly extinct."
The glaucous macaw is also known as the Lear's macaw or blue-throated hummingbird. It can be distinguished by its vivid blue feathers. The parrot measures 70 centimeters long and features a an impressive beak that is capable of slicing open nuts and seeds. This gorgeous bird is native to South America and can be found in a variety of habitats that include forests, lowland grasslands and wetlands.
This majestic bird is a sign of South American biodiversity. Its appearance is elegant, with its slender body, light build and bright blue feathers. The beak is curved and black, which helps it crack open the seeds and nuts that comprise a large portion of its diet. It is a beautiful bird that is often seen in bird shows. It is also a favourite in captivity, where it could be kept for a lifetime.
