Glaucous Macaw
The glaucous Macaw is among the rarest birds in the world. It is Critically Endangered and could become extinct in the wild.
This bird has been reported by aviculturists across the globe However, the most recent sighting was reported in 1992. The reported sighting was in southwestern Paraguay close to the city of Corrientes. The bird was male.
Origin
The Glaucous macaw is an endangered parrot species that is native to South America. This magnificent bird has a unique blue feather pattern and strong beak that is capable of breaking open hard nuts and seeds. Glaucous Macaws form monogamous long-term pairs, and both parents raise the chicks. They feed their chicks regurgitated food for the first few weeks after birth, before they begin to eat solid foods as they grow. Parents play a vital role in teaching young macaws to fly and forage.
The glaucous Macaw is extinct, yet rumors of its existence continue to spread across the globe. It is estimated that the glaucous Macaw was extinct in the 1800s because of cattle grazing and logging in yatay palm (Butia yatay) areas, where the birds typically gathered their food. The Glaucous Macaw is believed have made a comeback, and is often kept with its larger cousin, Lear's macaw.
The glaucous Macaw is found in subtropical rainforests of South America. They are most often located in areas with a lot of palm trees, and they are thought to be extremely adaptable to various types of forested habitats. These beautiful birds are territorial and defend the nesting and feeding area from intruders.
There have been a variety of reports on the glaucous macaw throughout the years, but they are considered to be unreliable. The most recent wild claim was made by an avicultural acquaintance of Ridgely who claimed to have spotted four Glaucous Macaws in Califomia. This is a completely absurd claim until it can be verified with hard evidence. The absence of any reliable data on this bird over the last century has caused many experts to believe that it is extinct, however they have always accepted the possibility of existence (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it survives, it is extremely unlikely to be seen in large numbers.
Habitat
The glaucous Macaw is an impressive bird, well-known for its large size and turquoise-blue coloration. The tail feathers and wings are long, which enhances its graceful and agile movement. This bird is an emblem of love and loyalty. Its beak is predominantly black and has a distinctive shape that allows it to break open seeds and nuts which make up 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 a high danger of disappearing. 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 resides in cliffs alongside major rivers.
The Glaucous Macaw was not rare in its limited range, despite the fact that there was no evidence of sightings since 1830. There were specimens taken up until the year 1860 (in Corrientes). The last known living Glaucous Macaw was seen at the Buenos Aires Zoo in 1936 and is believed to be from Brazil.
A re-examination of the historical records suggests that this species was very generalist in its habitat preferences with a preference for the savanna ecosystem, which was interspersed with palm "islands" and areas of riparian forest along river systems. It was a specialized feeder of palm fruit particularly those of the yatay (or chatay) palm (Butia). However, it also ate ripe and unripe fruits and berries, nuts, and even vegetable matter. It nested on steep slopes and in cliffs sometimes in tree cavities and laid an average clutch of two eggs.
This bird was likely to be gregarious and social, just like other parrots. It could live up to 14.8 years in captivity and was believed to be a dependable breeder that reproduced year after year. In the wild, the lifespan was probably between 50 and 80 years. The species was a strong disperser of seeds and could be a factor in the success of the palm yatay species in its natural habitats.
Feeding
The Glaucous Macaw (Anodorhynchus glaucus) is among the most magnificent of all the species of parrots, and its presence commands an immense impact in its environment. This large South American parrot is known for its vibrant blue feathers, yellow eyes, and the teardrop-shaped lipped on the lower portion of its beak.
Up until recently, very little was known about the diet of the Glaucous Macaw. The first detailed references I buy-macaw.com have found are 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 refer to the Hyacinthine Macaw (Anodorhynchus aureolarius), but I have no reason to believe that they are not applicable to this species.
It is likely that the Glaucous Macaw was a particular in the consumption of palm nuts, and also consumed other seeds, fruits and vegetable matter in small amounts. The diet of this species is likely to have been affected by the clearing of forests by early colonists for agriculture and cattle ranching and the destruction of the yatay palm (Butia yatay) from which it may have gotten a lot of its food.
In the wild it was commonplace to see the Glaucous macaw in subtropical forests and savannahs in which palm trees were present. It nestled in tree cavities, or on rocky banks or palm fronds. Females incubate and lay two eggs on average.
The young Glaucous Macaws rely on their parents for care until they are able to fly and are fully grown. Both the male and female are extremely dedicated to their offspring and will tirelessly hunt for food and shield them from predators.
Unfortunately, the Glaucous macaw isn't found in most of its former habitat. The disappearance of the magnificent bird is likely due to the continued trapping of birds for the pet industry, as well as disturbance of habitat, specifically the mass removal of palm yatays, which may have been its primary food source. The Glaucous macaw is listed as Critically Endangered.
Breeding
Glaucous macaws are typically monogamous couples with both parents taking part in raising the young. They breed during the dry season, when food is most abundant. The female will lay two to three eggs which are incubated by the mother for about 28 days. For the first few weeks after hatching the chicks are fed by the parents through regurgitation. 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.
Like all species of birds, glaucous macaws are extremely social creatures. They are active during daylight hours, and rest at night. They often seek refuge in cavities in trees or other suitable nesting places to sleep. They are extremely 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. About 20 glaucous macaws are believed to exist 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 in length and has a an impressive beak that is capable of breaking open nuts and seeds. This beautiful bird is native South America and can be found in diverse habitats such as forests, lowland grasslands and wetlands.
This magnificent 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 curved and black, which helps it break open the seeds and nuts which comprise a significant portion of its diet. It's a stunning bird, and is often featured in bird shows. It is also popular in captivity where it can live a lifetime.
