Glaucous Macaw
The glaucous macaw is one of the rarest birds on earth. It is in serious danger and could even be extinct.
The bird has been reported by aviculturists in various countries However, the most recent sighting was reported in 1992. The alleged sighting was reported to be in the southwest region of Paraguay close to the city of Corrientes. The bird was a male.
Origin
The Glaucous macaw is a threatened parrot species that is native to South America. This magnificent bird has a distinctive blue feather pattern and a powerful beak that is capable of breaking open hard seeds and nuts. Glaucous macaws form long-term monogamous pairs and both parents help raise the chicks. The chicks are fed regurgitated food for the first couple of weeks of life and then a variety of solid foods as they grow. The parents also play a vital role in teaching young macaws to fly and forage.
The glaucous Macaw is thought to be extinct in the wild, yet stories of this gorgeous bird's existence persist throughout the world. It is estimated that the glaucous macaw extirpated in the 1800s because of cattle grazing and logging in yatay palm (Butia yatay) trees, where these birds mostly ate their food. It is believed that the glaucous macaw made a comeback in captivity in the wild, where it is raised alongside its larger relative Lear's macaw.
The glaucous Macaw lives in subtropical rainforests of South America. They are typically found in areas that have plenty of palm trees, and are known to be highly adaptable to different types of forested habitats. These beautiful birds can be territorial and defend the feeding and nesting area from intruders.
There have been a lot of reports involving the glaucous macaw over the years, but they are considered to be unreliable. The most recent claim of a wild incident is an friend of Ridgely's that claimed to have witnessed four Glaucous macaws in Califomia. This claim is unacceptable until it is substantiated with hard evidence. The absence of any credible records of this bird in the past century has caused many experts to conclude that it is likely extinct, however they have always accepted the possibility of survival (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it survives it will be extremely uncommon to observe large numbers.
Habitat
The Glaucous Macaw is a stunning bird, renowned for its large size and turquoise-blue coloring. The long tail and wings enhance its graceful and agile movement. This bird is also an emblem of affection and loyalty. Its beak is mostly black and has a unique shape that allows it to open nuts and seeds, which make up a large portion of its diet.
IUCN has classified the Glaucous Macaw as Critically Endangered. It says that there is a very small population of the bird and it is at risk of extinction. The species was previously relatively widespread, but it is found in northern Argentina, southern Paraguay and north-eastern Uruguay and Brazil from Parana state southwards, where it nestted in cliffs along major rivers.
The Glaucous Macaw was not rare in its small area, despite the fact that there was no proof of sightings since 1830. Specimens were collected until the year 1860 (in Corrientes). The last known living Glaucous Macaw was displayed 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 a more generalist in its preferences for habitat and preferred the savanna ecosystem, which was interspersed with palm "islands" and areas of riparian forest along rivers. It was a particular in the consuming of palm fruit, especially those of the yatay (or chatay) palm (Butia). However it also ate ripe and unripe fruits, nuts, berries, and other vegetable matter. It nests on slopes that are steep on cliffs, in cliffs, and occasionally in tree cavities.
This bird was likely gregarious and social, like other parrots. It was said that it could live for up to 14.4 years in captivity, and was best place to buy macaw a reliable breeder who reproduced year after year. In the wild, its life expectancy 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 in its natural habitat.
Feeding
The Glaucous Macaw is one of the most stunning parrots. Its presence has a strong impact on the environment. This huge South American parrot is known for its vibrant blue feathers, yellow eyes, and the teardrop-shaped lipped on its lower beak.
Until recently very little was known about the feeding habits of the Glaucous Macaw. The first detailed references I 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 book "As Birds of the Brazilian Forests". Both are about the Hyacinthine Macaw, Anodorhynchus Aureolarius. There is no reason to think that they could not apply to this species.
The Glaucous macaw is likely to have been a specialist feeder, taking only palm nuts, but also small amounts of other fruits, seeds and vegetable matter. The diet of this species is likely to be influenced by the clearance of forests by the early colonists to cultivate and cattle ranching, as well as the felling of the yatay palm (Butia yatay) from which it may have gotten a lot of its food.
In the wild it was commonplace to find the Glaucous macaw in savannahs and subtropical forests in which palm trees were present. It nestled 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, meaning they rely on their parents to take care of them until they're fully fledged and can fly. Both the male and female are extremely dedicated to their offspring and constantly hunt for food and defend them from predators.
Unfortunately unfortunately, the Glaucous macaw isn't found in its former habitat. The disappearance of the majestic bird is likely due to trapping that continues for the pet industry, as well as habitat disruption, especially the mass removal of palm yatays that may have been its primary food source. The Glaucous macaw is listed under Critically Endangered.
Breeding
Glaucous Macaws are monogamous, long-term pairs. Both parents are involved in raising their young. They breed during the dry season when the availability of food is at its greatest. Females lay a clutch of two to three eggs, which are incubated for around 28 days. Once the chicks hatch they are fed by their parents through regurgitation for the first few weeks of their life. Then the young macaws begin to explore their surroundings and begin to learn to eat themselves. They also learn how to fly and forage.
The glaucous Macaw is highly social bird. They are active during daylight hours, and take a break at night. During the night they usually seek refuge in tree cavities or other nesting areas that are suitable. They are extremely vocal and their calls can be heard throughout the forest during the day.
Although it is hoped the species will be able to recover from its decline in the wild, the bird faces numerous threats, such as the loss of habitat illegal trapping for the pet trade and deforestation. It is believed that there are only about 20 glaucous macaws in the wild. The IUCN has classified the bird as "Critically endangered--possibly extinct."
The glaucous Macaw is also known as Lear's Macaw, or the blue-throated Hummingbird, is distinguished by its vivid blue feathers. The parrot is 70 centimeters in length and has a an impressive beak that is capable of breaking open nuts and seeds. This gorgeous bird is native to South America and can be found in diverse habitats that include grasslands, lowland forests and wetlands.
This majestic bird is a symbol of South American biodiversity. Its elegant appearance with its slim build, lightweight body and vivid blue feathers. Its black and curved beak makes it easier to crack open seeds and nuts, which comprise a significant portion of its diet. It's a beautiful bird, and it's often used in bird shows. It is also popular in captivity where it can live for a long time.
