Glaucous Macaw
The glaucous Macaw is among the rarest birds in the world. It is Critically Endangered and could be extinct in the wild.
Many aviculturalists have reported sightings of this bird however the most recent sighting was in 1992. This alleged sighting was in southwest Paraguay close to the city of Corrientes. The bird was male.
Origin
The Glaucous Macaw is a bird native to South America. It is endangered. This majestic bird is distinguished by its unique blue feather pattern and powerful beak that is capable of breaking open hard nuts and seeds. Sinatra Macaws for Sale form monogamous long-term pair, and both parents raise the chicks. The chicks are fed regular food for the first couple of weeks of their lives before being fed solid food as the chicks develop. Parents are also responsible for teaching young macaws to fly and hunt.
The glaucous macaw is believed to be extinct in the wild, yet reports of this beautiful bird's existence are still spreading throughout the world. The Glaucous Macaw is believed have been extinct in the 1800s because of logging and cattle grazing on yatay (Butia) palm groves from which the birds would gather their food. The Glaucous Macaw is believed be making a comeback and is often kept with its larger mate, Lear's macaw.
The glaucous Macaw can be found in sub-tropical rainforests of South America. They are typically found in areas that have plenty of palm trees, and they are thought to be extremely adaptable to various types of forested habitats. These beautiful birds are territorial and will defend the nesting and feeding areas from intruders.
There have been a number of reports on the glaucous macaw through the years, but they are considered to be not reliable. 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 is confirmed with hard evidence. The absence of any credible data on this bird over the past century has led many experts to think that it's likely extinct, however 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 is highly unlikely to make it to large numbers.
Habitat
The glaucous Macaw is an impressive bird, known for its huge size and turquoise-blue coloring. The tail and wings are long, enhancing its graceful and agile moves. The bird is an emblem of loyalty and love. Its beak is mostly black and is distinctive in its shape. It allows it to break open nuts and seeds, which constitute a significant portion of its diet.
IUCN has classified the Glaucous Macaw as Critically Endangered. It states that there is a very tiny population of this bird and it is at risk of extinction. This species was formerly quite widespread, but today it is found in northern Argentina, southern Paraguay and north-eastern Uruguay and Brazil from Parana state southwards, where it was a nesting place in cliffs along major rivers.
Although there have been no confirmed sightings of this species since 1830, the Glaucous Macaw seemed not to be extremely rare within its comparatively small range; specimens were collected up to 1860 (in Corrientes). The last living Glaucous Macaw, believed to originate from Brazil was displayed in the Buenos Aires Zoo back in 1936.
A reassessment of the historical records suggests that this species was very generalist in its habitat preferences and preferred savanna habitat intermingled with palm "islands" and forests of riparian along river systems. It was a specialist in the consuming of palm fruit, especially those of the yatay (or chatay) palm (Butia). However, it also ate ripe and unripe fruits as well as berries, nuts and other vegetable matter. It is a nesting place on steep slopes or in cliffs, and also in tree cavities.
This bird was likely to be gregarious and social, like other parrots. It was able to live up to 14.8 years in captivity. It was said to be a dependable breeder that reproduced year after year. In the wild, its lifespan was likely to be between 50 and 80 years. This species was a powerful seed disperser and could have contributed to the success of the yatay palm 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 an immense impact in its environment. This large South American bird is known for its vibrant blue feathers and yellow eyes and also for its distinctive teardrop-shaped lappet which adorns the lower part of its beak.
Up until recently, very little was known about eating habits and diet of the Glaucous macaw. The earliest detailed references that I have found are two works by H.W. Bates' "The Naturalist on the amazons", first published in 1863, which describes his 11-year sojourn in Brazil. Later in his book "As Birds of the Brazilian Forests" He wrote about the same experience. Both of these references to the Hyacinthine Macaw (Anodorhynchus aureolarius) However, I have no reason to think that they're not applicable to this species.
The Glaucous macaw is believed to be a specialist feeder, taking only palm nuts however, there were also tiny amounts of other seeds, fruits and other matter. The diet of this species is likely to be affected by the clearing of forests by early colonists for agriculture and cattle ranching and the removal of the yatay palm (Butia yatay) from which it may have gotten a lot of its diet.
In the wild it was commonplace to see the Glaucous macaw in savannahs and subtropical forests where palm trees were present. It hid in tree cavities or on rocky banks and palm fronds. The female incubates and then lays two eggs per.
The young Glaucous Macaws are altricial, which means they depend on their parents to care for them until they are fully grown and fly. Both males and females are dedicated to their offspring, and will hunt for food and defend them against predators.
Unfortunately unfortunately, the Glaucous macaw is no longer present in the majority of its former habitat. The disappearance of this magnificent bird is probably due to the continuing trapping of pets for the pet trade as well as disturbance to habitat, specifically the wholesale removal of yatay palms where it could have gotten its main food supply. The Glaucous Macaw is listed as Critically Endangered.
Breeding
Glaucous macaws usually form long-term monogamous pairs 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. The female lays an egg clutch that ranges from two to three eggs that are incubated for around 28 days. Once the chicks hatch they are fed by their parents via regurgitation during the first few weeks of their lives. Then Ziggy hyacinth macaw parrots for sale begin to explore their surroundings and begin to learn to feed themselves. They also learn how to fly and forage.
The glaucous Macaw can be described as a extremely social bird. They are active during daylight hours and rest at night. In the evening they usually seek refuge inside tree cavities or other nesting spots that are suitable. They are very vocal and their calls can be heard throughout the forest during 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. There are only about 20 glaucous Macaws that are believed to exist in the wild. The IUCN classifies the bird as "Critically Endangered - possibly Extinct."
The glaucous macaw is known as the Lear's macaw or blue-throated hummingbird, and is distinguished by its vibrant blue feathers.
