Glaucous Macaw
The glaucous macaw is considered to be one of the rarest birds in the world. It is critically endangered and may even be extinct.
Various Aviculturalists have reported sightings of this bird However, the most recent sighting was in 1992. The alleged sighting was reported to have occurred in southwestern Paraguay, near the city of Corrientes. The bird was a male.
Origin
The Glaucous Macaw is a bird native to South America. It is endangered. This majestic bird is distinguished by a blue feather pattern, and a powerful beak capable of cracking open nuts and seeds. Glaucous Macaws form monogamous long-term couples, and both parents raise the chicks. The chicks are fed a diet of regurgitated food during the first few weeks of life before being fed solid food as the chicks grow. The parents also play a vital role in teaching the young macaws how to fly and hunt.
The glaucous macaw is considered to be extinct in the wild, but stories of this gorgeous bird's existence continue to spread all over the world. The glaucous Macaw is believed to 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. It is believed that the glaucous macaw returned to captivity, where it is often raised alongside its larger relative, Lear's macaw.
In terms of habitat The glaucous macaw is able to be found in the sub-tropical forests of South America. They are usually found in areas with abundant palm trees, and they are thought to be extremely adaptable to different types of forested habitats. These beautiful birds can be territorial and will protect the feeding and nesting area from intruders.
There have been a variety of reports on the glaucous macaw throughout the years, but many 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 verified with hard evidence. The absence of any credible evidence of this bird in the past century has been a reason for many experts to conclude that it is likely extinct, but they have always accepted a 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 stunning bird, well-known for its large size and turquoise-blue coloring. The tail and wings are long, which aids in its graceful and agile movements. The bird is also an emblem of loyalty and love. Its beak is predominantly black and has a distinctive shape that allows it to crack open seeds and nuts which comprise a large portion of its diet.
IUCN has classified the Glaucous Macaw as Critically Endangered. It notes that there is a tiny population of this bird, and that it is at a the risk of becoming extinct. This species was formerly relatively widespread, but it is only found in northern Argentina and southern Paraguay and north-eastern Uruguay and Brazil from Parana state southwards where it nestted in cliffs along major rivers.
The Glaucous Macaw was not rare in its small area, even though there were no reliable sightings after 1830. Specimens were collected until 1850 (in Corrientes). The last known living Glaucous Macaw was seen at the Buenos Aires Zoo in 1936 and is believed to be from Brazil.
The reassessment suggests that the species is a generalist, preferring savanna habitat interspersed with palm "islands" and riparian forests 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 and unripe fruits, nuts, berries, and vegetable matter. It nests on steep slopes or in cliffs, and also in tree cavities.
As with other parrots this bird was social and was likely to be gregarious. It could live up to 14.8 years in captivity and was said to be a reliable breeder, reproducing year after year. Its life expectancy in the wild was perhaps about 50 to 80 years. The species was a strong disperser of seeds, and could have contributed towards the success of the palm yatay species in its natural habitat.
Feeding
The Glaucous Macaw (Anodorhynchus glaucus) is one of the most magnificent of all the species of parrots and its presence has an immense impact in its surroundings. This massive South American bird is known for its vivid blue feathers and eyes that are yellow, as well as its distinctive teardrop-shaped lipped sleeve that covers the lower portion of its beak.
Up until recently, very little was known about the eating habits of the Glaucous Macaw. The earliest detailed references I have discovered are in two books by H.W. Bates' "The Naturalist on Amazons" first published in 1863, and describes his 11-year journey in Brazil. In his later book "As Birds of the Brazilian Forests" Bates wrote about the same experience. Both of these are about the Hyacinthine Macaw Anodorhynchus Aureolarius. There is no reason to believe that they don't apply to this species.
It is probable that the Glaucous Macaw was a specialized feeder of palm nuts and also consumed other seeds, fruits, and vegetable matter in small quantities. The diet of this species was likely heavily influenced by the clearing of forests for farming and cattle-ranching by early colonists as well as the removal of yatay (Butia) palms from which it derived a lot of its nutrition.
In the wild the Glaucous Macaw was often found in subtropical forests containing cliffs and savannahs with palm trees, where it nested in tree cavities, 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 rely on their parents for care until they fly and are fully full fledged. Both the males and females are dedicated to their offspring, and hunt for food and defend them against predators.
Unfortunately unfortunately, the Glaucous macaw is no longer found in most of its former habitat. The disappearance of this majestic bird is most likely due to the continued trapping of pets for the pet trade, as well as habitat disturbance, particularly the more info massive clearing of yatay palms from which it may have obtained its main food supply. The Glaucous macaw is listed under Critically Endangered.
Breeding
Glaucous macaws usually form long-term monogamous couples with both parents taking an active role in the raising of the young. They breed during the dry season, when food availability is at its greatest. Females lay an egg clutch of between two and three eggs, which are incubated for around 28 days. After hatching they are fed by their parents via regurgitation for the first few weeks of their life. The young macaws then begin exploring and learning to feed themselves. They are also taught how to fly and forage.
Like all birds, glaucous macaws are extremely social creatures. They are active during daylight hours, and take a break at night. They will often seek shelter in tree cavities or other suitable nesting places to sleep. They are extremely 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 pet trade, and deforestation. It is believed that there are less than 20 glaucous macaws in the wild. The IUCN classifies the bird as "Critically Endangered - possibly Extinct."
The glaucous macaw, also known as Lear's Macaw, or the blue-throated Hummingbird is distinguished by its bright blue feathers. It is a large bird, measuring 70 centimeters in length, and has a strong beak that can crack open tough nuts and seeds. This beautiful bird is native to South America, and it can be found in many habitats, including forests, dry lowland grasslands, and wetland.
This magnificent bird is a symbol of South American biodiversity. Its appearance is elegant with its slender body, bright blue feathers, and lightweight build. Its beak is curvaceous and black, which aids it open the nuts and seeds that make up a major portion of its diet. It is a beautiful bird, and is frequently featured in birds shows. It is also a favourite in the wild, where it can remain for a long time.
