Glaucous Macaw

The glaucous Macaw is among the rarest birds in the world. It is considered Critically Endangered and could be extinct in the wild.

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 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 magnificent bird is characterized by blue feathers, and a powerful beak that is capable of breaking open nuts and seeds. Glaucous macaws have been known to form long-term monogamous couples and both parents assist in raising the chicks. The chicks are fed regurgitated food during the first few weeks of their lives before being fed solid food as they grow. Parents are also responsible for teaching young macaws to fly and hunt.

The glaucous Macaw is extinct, yet rumors of its existence persist all over the world. The glaucous Macaw is believed to be extinct by the 1800s because of cattle grazing on yatay (Butia) palm groves where the birds would gather their food. It is believed that the glaucous chestnut fronted macaw price has returned to captivity in the wild, where it is raised alongside its larger relative, Lear's macaw.

In terms of habitat the glaucous macaw can be found in subtropical forests of South America. They are usually located in areas where there are numerous palm trees. They are also highly adaptable to a variety of forest habitats. These beautiful birds are also known to be very territorial and will defend their feeding and nesting areas from invaders.

There have been a lot of reports on the glaucous macaw over the years, but most are considered to be not reliable. The most recent wild claim was reported by an avicultural friend of Ridgely who claimed to have seen four Glaucous Macaws in Califomia. This is completely untrue until it is verified with solid evidence. The absence of any reliable data on this bird over the past century has led many experts to think that it's likely extinct, yet they have always been open to a remote possibility of its survival (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it does survive, it is extremely unlikely to make it to huge numbers.

Habitat

The Glaucous Macaw is a stunning bird, well-known for its large size and turquoise-blue coloration. The tail feathers and wings are long, which enhances its graceful and agile movements. This bird is an emblem of loyalty and love. Its beak is primarily black and is distinctive in its shape. It allows it to break open seeds and nuts, which constitute a significant portion of its diet.

IUCN has classified the Glaucous Macaw as Critically Endangered. It notes that there is only a small population of this bird and it is in risk of extinction. The species was once relatively widespread, but it is found only in northern Argentina, southern Paraguay, north-eastern Uruguay and Brazil from Parana state southwards where it is nestled in cliffs on major rivers.

Although there have been no confirmed sightings of this species since 1830 The Glaucous macaw shop seemed not to be extremely rare within its comparatively small range; specimens were taken from 1830 to 1860 (in Corrientes). The last living Glaucous Macaw, believed to originate from Brazil was seen in the Buenos Aires Zoo back in 1936.

Re-evaluation of the historical records suggests that this species was a very generalist in its preferences for habitat and preferred the savanna ecosystem, which was interspersed with palm "islands" and bands of riparian forest along rivers. It was a specialized for the consumption of palm fruits, especially those of the yatay (or chatay) palm (Butia). However, it also ate ripe and unripe fruits, nuts, berries, and even vegetable matter. It nested on steep slopes and in cliffs, sometimes in tree cavities, and laid an average clutch of two eggs.

The bird was likely to be gregarious and social, just like other parrots. It was believed that it could live up to 14.4 years in captivity and was a reliable breeder that reproduced year after year. The lifespan of the species in the wild was perhaps about 50 to 80 years. This species was a formidable seed disperser, and could have contributed to the success of the yatay palm in its native habitats.

Feeding

The Glaucous Macaw (Anodorhynchus glaucus) is among the most beautiful of the species of parrots and its presence has an enormous impact on its surroundings. This huge South American parrot is known for its vibrant blue feathers, bright yellow eyes and the teardrop-shaped lappet on the lower portion of its beak.

Until recently very little was known about the diet of the Glaucous Macaw. The earliest references to this subject that I have come across 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 book "As Birds of the Brazilian Forests". Both of them are about the Hyacinthine spix's macaw lifespan, Anodorhynchus Aureolarius. There is no reason to believe that they don't apply to this species.

The Glaucous macaw is likely to be a specialist eater, consuming only palm nuts however, there were also tiny amounts of other seeds, fruits and vegetable 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, as well as the removal of the yatay palm (Butia yatay) from which it could have gotten its majority of its diet.

In the wild, the Glaucous Macaw was found in subtropical forests with cliffs and savannahs with palm trees where it nested in tree cavities, on rocky banks or the palm fronds' top. On average, a clutch of two eggs was laid and incubated by the female.

The young Glaucous Macaws are altricial, which means they depend on their parents to take care of them until they are fully fledged and can fly. Both males and females are extremely committed to their young and will constantly hunt for food and shield them from predators.

Unfortunately the Glaucous macaw has been found in its former habitat. The disappearance of this magnificent bird is probably due to the ongoing trapping for the pet trade, as well as disturbance to habitat, specifically the wholesale clearing of yatay palms from which it could have gotten its main food supply. The Glaucous Macaw is listed as Critically Endangered.

Breeding

Glaucous Macaws form monogamous long-term pairs. Both parents are involved in raising their young. They breed in the dry season, when food is most abundant. The female lays a clutch of two to three eggs, which are incubated for around 28 days. In the initial few weeks after hatching the chicks are fed by their parents through regurgitation. Macaws are then able to explore and to feed themselves. They also learn to fly and forage.

The glaucous Macaw is a very social bird. They are active during daylight hours, and rest during the night. During the night they usually seek shelter inside tree cavities or other nesting spots that are suitable. Their calls can be heard in the forest throughout the day.

The species is expected to recover from the decline, but it is in danger of being wiped out by habitat loss illegal trapping of the bird for the macau pet shop; buying-a-macaw-online28037.blogoscience.Com, market, 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 known as the Lear's macaw or blue macaw price-throated hummingbird, and is distinguished by its vivid blue feathers. The hyacinth parrot price is 70 centimeters long and has powerful beaks that are capable of breaking open seeds and nuts. This gorgeous bird is native to South America, and it is found in various habitats such as grasslands, forests, dry lowland, and wetlands.

This magnificent bird is a sign of South American biodiversity. It has a regal appearance with its slim body, light weight and vivid blue feathers. Its black and curved beak makes it easier to crack open seeds and nuts, which are a large part of its diet. It is a beautiful bird that is often seen in bird shows. It is also a favourite in the wild, where it can be kept for a lifetime.
