Glaucous Macaw

The glaucous macaw is one of the world's rarest birds. It is in danger of disappearing and may even be extinct.

A variety of birdwatchers have reported sightings 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 male.

Origin

The Glaucous macaw is an endangered parrot species that is native South America. This magnificent bird has a distinctive blue feather pattern and a powerful beak capable of breaking open hard seeds and nuts. Glaucous macaws form long-term monogamous pairs and both parents assist in raising the chicks. The chicks are fed regurgitated food in the first few weeks of life before being fed solid food as they grow. Parents are also responsible for teaching the young macaws to fly and hunt.

The glaucous Macaw is extinct, yet rumors of its existence continue to circulate across the globe. The Glaucous Macaw is believed be extinct by the 1800s due to cattle grazing on yatay (Butia) palm groves from which the birds would gather their food. It is currently believed that the glaucous Macaw has returned to captivity and is usually kept with its larger cousin, Lear's buy Macaw bird (www.smstender.ru).

The glaucous catalina macaw price lives in sub-tropical rainforests of South America. They are typically located in areas where there are numerous palm trees. They are also known to be extremely adaptable to different types of forest habitats. These beautiful birds are also recognized as being very territorial and will defend their nesting and feeding areas from intruders.

In the past, there have been a variety of reports of the glaucous macaw, but they are generally considered unreliable. The most recent claim of a wild occurrence involves a avicultural acquaintance of Ridgely's who claimed to have observed four Glaucous macaws in Califomia. This claim is unacceptable until it can backed up by solid evidence. The absence of any credible evidence of this bird in the last century has been a reason for many experts to believe that it is extinct, yet they have always been open to an extremely remote possibility of its survival (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it is able to survive it will be extremely uncommon to see large numbers.

Habitat

The macaw with the glaucous is a striking bird, renowned for its huge size and dazzling turquoise-blue coloration. The long tail and wings accentuate its graceful and agile movement. This bird is also a symbol of love and loyalty. Its beak is mostly black and has a distinctive shape that allows it to break open seeds and nuts, which comprise a large part of its diet.

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

The Glaucous Macaw was not rare in its relatively small area, even though there was no proof of sightings after 1830. There were specimens collected up until the year 1860 (in Corrientes). The last known living Glaucous Macaw was exhibited at the Buenos Aires Zoo in 1936 and is believed to be from Brazil.

A re-examination of the historical documents suggests that this species was more 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 specialist feeder of palm fruit especially those of the yatay (or chatay) palm (Butia). However it also ate ripe or unripe fruits and berries, nuts, and even vegetable matter. It nests on slopes that are steep, in cliffs and sometimes in tree cavities.

As with other parrots this bird was social and was likely to be gregarious. It was reported that it could live for up to 14.4 years in captivity, and was a reliable breeder that reproduced year after year. In the wild, the lifespan was probably between 50 and 80 years. This species was a powerful disperser of seeds and may be a factor in the success of the palm yatay in its natural habitat.

Feeding

The Glaucous Macaw is one of the most stunning parrots. Its presence can have an enormous impact on the environment. This large South American bird is known for its vivid blue feathers and yellow eyes, and also for its distinctive teardrop-shaped lappet which adorns the lower part of its beak.

In the past, little was known about the feeding habits and diet of the Glaucous macaw. The earliest references to this subject that I have located are two works by H.W. Bates, "The Naturalist on the Amazons" first published in 1863, detailing 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 price, Anodorhynchus Aureolarius. There is no reason to believe that they don't apply to this species.

The Glaucous macaw is believed to have been a specialist feeder, consuming mainly palm nuts however, there were also small amounts of other fruits, seeds and vegetable matter. The diet of this species is likely to have been affected by the clearing of forests by early colonists to cultivate and cattle ranching as well as the felling of the yatay palm (Butia yatay) from which it may have received much of its food.

In the wild, it was common to see the Glaucous macaw in subtropical forests and savannahs where palm trees were present. It was found in tree cavities, or on rocky banks and palm fronds. The female incubates and lays two eggs on average.

The young Glaucous Macaws rely on their parents for care until they fly and fully full fledged. Both males and females are dedicated to their offspring, and hunt for food and defend them from predators.

Unfortunately, the Glaucous macaw has been found in most of its former habitat. The disappearance of this majestic bird is most likely due to the continued trapping for the pet trade and habitat disturbance, particularly the massive removal of yatay palms which it may have obtained its main food supply. The Glaucous Macaw is listed as Critically Endangered.

Breeding

Glaucous Macaws form monogamous pair. Both parents are involved in the raising of their children. They breed in the dry season, Buy macaw bird which is when the food supply is at its highest. Females lay two to three eggs that are incubated by the mother for about 28 days. After hatching they are fed by their parents via regurgitation during the first few weeks of their lives. Macaws are then able to explore and Buy Macaw Bird to feed themselves. They are also taught to fly and hunt for food.

Like all birds, glaucous macaws are social animals. They are active during daylight hours, and rest during the night. At night they often seek refuge in tree cavities or other nesting areas that are suitable. Their calls can be heard throughout the forest throughout the day.

Although it is hoped the species will recover from its decline in the wild, the bird is facing many threats, including 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 has classified the bird as "Critically endangered, possibly extinct."
