Glaucous Macaw
The glaucous Macaw is one of the rarest birds in the world. It is Critically Endangered and could be extinct in the wild.
The bird has been reported by aviculturists from various countries, but the latest sighting was in 1992. This alleged sighting occurred in southwestern Paraguay, near 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 features a distinctive blue feather pattern and a powerful beak that is capable of cracking open tough nuts and seeds. Glaucous macaws have been known to 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 grow. The parents also play a vital role in teaching young macaws to fly and hunt.
The glaucous Macaw has gone extinct, but rumors about its existence persist across the globe. 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 gathered their food. The Glaucous Macaw is believed have returned, and is usually kept with its larger cousin, Lear's macaw.
In terms of habitat, the glaucous macaw can be found in sub-tropical forests of South America. They are typically found in areas that have many palm trees. They are also known to be extremely adaptable to different types of forest habitats. These beautiful birds are known to be very territorial and will protect their nesting and feeding areas from trespassers.
There have been a variety of reports involving the glaucous macaw throughout the years, but most are considered to be unreliable. The most recent claim of a wild incident is an avicultural acquaintance of Ridgely's who claimed to have observed four Glaucous macaws in Califomia. This is a ridiculous claim until it can backed up with evidence. The lack of any acceptable data on this bird over the past century has led many experts to think that it's likely extinct, however they have always been open to the possibility of existence (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it does survive, it will be extremely uncommon to see large numbers.
Habitat
The Glaucous Macaw is a magnificent bird, well-known for its size and turquoise-blue coloring. The long tail and wings accentuate its graceful and agile moves. This bird is also an emblem of affection and loyalty. Its beak is predominantly black and has a unique shape that allows it to break open seeds and nuts, which make up a large part of its diet.
IUCN has classified the Glaucous Macaw as Critically Endangered. It says that there is a very tiny population of this bird and it is at risk of extinction. The species was once quite widespread, but today it is only found in northern Argentina as well as southern Paraguay and north-eastern Uruguay and Brazil from Parana state southwards where it was a nesting place in cliffs along major rivers.
The Glaucous Macaw was not rare in its limited range, despite the fact that there was no proof of sightings since 1830. There were specimens taken up until the year the year 1860 (in Corrientes). The last known living Glaucous spix's Macaw Lifespan was exhibited at the Buenos Aires Zoo in 1936 and is believed to have come from Brazil.
The reassessment suggests that the species is a generalist, preferring savanna habitat interspersed with palm "islands", and riparian forests along river systems. It was a particular feeder of palm fruits, spix's macaw Lifespan particularly those of the chatay palm (Butia yatay) however, it was likely to also consume ripe and unripe fruit as well as berries, nuts and vegetable matter. It nested on steep slopes and in cliffs, sometimes in tree cavities and laid an average clutch of two eggs.
Like all parrots, this bird was social and was likely to be gregarious. It was said that it could live up to 14.4 years in captivity, and was a reliable breeder who reproduced year after year. Its life expectancy in the wild was 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 habitats.
Feeding
The Glaucous Macaw (Anodorhynchus glaucus) is one of the most magnificent of all the species of parrots and has a a powerful impact in its surroundings. This huge South American bird is known for its vibrant blue feathers and yellow eyes, and also for its distinctive teardrop-shaped lipped sleeve that covers the lower portion of its beak.
Until recently very little was known about the feeding habits of the Glaucous buy macaw parrot. The first detailed references I have found are in two works by H.W. Bates, "The Naturalist on the Amazons" first published in 1863 on his 11-year stay in Brazil and later in his work "As Birds of the Brazilian Forests". Both of these are about the Hyacinthine Macaw (Anodorhynchus aureolarius) however I see no reason to believe that they are not applicable to this species.
It is probable that the Glaucous spix's macaw lifespan was a specialized feeder of palm nuts and also consumed 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 destruction of the yatay palm (Butia yatay) from which it could have gotten its majority of its nutrition.
In the wild it was commonplace to find the Glaucous macaw in savannahs and forests that were subtropical where palm trees were found. It hid in tree cavities or on rocky banks and palm fronds. On average two clutches of eggs was laid and incubated by the female.
The young Glaucous Macaws are altricial, which means they depend on their parents to care for them until they become fully fledged and can fly. Both the males and females are very committed to their offspring and hunt for food and defend them against predators.
Unfortunately, the Glaucous macaw is no longer found in most of its former habitat. The disappearance of this magnificent bird is likely to be due to trapping that continues for the pet industry as well as habitat disruption, especially the wholesale clearing of palm yatays which may have been its main food source. The Glaucous macaw is listed as Critically Endangered.
Breeding
Glaucous macaws are typically monogamous couples with both parents taking an active role in the raising of the young. They breed during the dry season when the availability of food is at its highest. Females lay an egg clutch that ranges from two to three eggs, which are incubated for around 28 days. In the initial few weeks following hatching, the chicks are fed by their parents through regurgitation. The macaws' young begin to explore their surroundings and begin to learn to feed themselves. They also learn to fly and forage.
The glaucous Macaw can be described as a extremely social bird. They are active during daylight hours and take a break at night. They usually seek shelter in tree cavities or other suitable nesting places for the night. Their calls can be heard throughout the forest throughout the day.
The species is expected to recover from the decline, however it faces many threats including habitat loss illegal trapping of the bird for pet trade, and deforestation. About 20 glaucous macaws are believed to be in the wild. The IUCN has classified the bird as "Critically endangered--possibly extinct."
The glaucous macaw is known as the Lear's macaw, or the blue macaw bird price-throated hummingbird. It is distinguished by its bright blue feathers. The parrot measures 70 centimeters long and features a powerful beaks that are capable of breaking open seeds and nuts. This beautiful bird is native South America and can be found in diverse habitats that include forests, lowland grasslands and wetlands.
This majestic bird is a symbol of South American biodiversity. Its appearance is elegant with its slim body, light build and bright blue feathers. The black and curly beak allows it to break open nuts and seeds, which are a large part of its diet. It is a beautiful bird, and is frequently featured in bird shows. It is also popular in captivity where it can live for a lifetime.
