Glaucous Macaw
The glaucous Macaw is one of the rarest birds in the world. It is Critically Endangered and could be extinct in the wild.
This bird has been reported by aviculturists across the globe, but the latest sighting was recorded in 1992. The reported sighting was in the southwest region of Paraguay close to the city of Corrientes. The bird was male.
Origin
The Glaucous Macaw is a parrot native to South America. It is endangered. This magnificent bird features a distinctive blue feather pattern and a powerful beak that is capable of breaking open hard seeds and nuts. Glaucous macaws have been known to form long-term monogamous families and both parents assist in raising the chicks. They feed their chicks regurgitated food for the first few weeks after birth, and then they begin to eat solid food as they grow. Parents are also responsible for teaching young macaws to fly and hunt.
The glaucous Macaw is thought to be extinct in the wild, but rumors of this beautiful bird's existence persist across the globe. It is believed that the glaucous macaw was extirpated in the 1800s because of logging and cattle grazing of yatay palm (Butia yatay) groves, where these birds typically gathered their food. The glaucous Macaw is believed to have made a comeback, and is often kept with its larger mate, Lear's macaw.
In terms of habitat the glaucous macaw can be found in sub-tropical forests of South America. They are most often located in areas where there are many palm trees. They are also highly adaptable to a variety of forested environments. 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 throughout the years, but many are considered to be not reliable. The most recent report of a wild event is a avicultural acquaintance of Ridgely's who claimed to have witnessed four Glaucous macaws in Califomia. This is completely untrue until it is verified with solid evidence. Many experts have concluded that this bird is likely extinct because there are no records in the last century. However they have been willing to accept a small chance of its survival. If it survives, it will be extremely uncommon to witness large numbers.
Habitat
The Glaucous Macaw is a stunning bird, well-known for its large size and turquoise-blue coloration. Its wings and tail feathers are long, which enhances its fluid and graceful moves. This bird is also an emblem of affection and loyalty. Its beak is mostly black, and it is distinctive in its shape. It allows it to break open seeds and nuts which constitute a significant part of its diet.
The Glaucous Macaw is considered Critically Endangered by the IUCN and the IUCN states that it has a small population and is at a high danger of disappearing. This species was once widespread, but is now only found in northern Argentina and south Paraguay and north-eastern Uruguay and Brazil from Parana state to the south, where it nests in cliffs that run alongside major rivers.
The Glaucous Macaw was not rare in its relatively small area, despite the fact that there were no reliable sightings since 1830. The specimens were collected until 1860 (in Corrientes). The last known living Glaucous Macaw was displayed at the Buenos Aires Zoo in 1936 and is believed to have come from Brazil.
A re-examination of the historical records 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 forests of riparian along rivers. It was a specialized for the consumption of palm fruits particularly those of the yatay (or chatay) palm (Butia). However, it also ate ripe and unripe fruits as well as berries, nuts and vegetable matter. It nests 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 believed that it could live to 14.4 years in captivity, and was a reliable breeder that reproduced year after year. In the wild, its life expectancy was likely to be between 50 and 80 years. This species was a powerful disperser of seeds and may have contributed towards the success of the palm yatay species in its natural habitats.
Feeding
The Glaucous Macaw (Anodorhynchus glaucus) is one of the most beautiful of the species of parrots and its presence has a powerful impact in its environment. This massive South American parrot is known for its vibrant blue feathers, bright yellow eyes and the teardrop-shaped lappet on its lower beak.
As of the time of writing, little was known of the eating habits and diet of the Glaucous macaw. The first detailed references I have come across 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 them are about the Hyacinthine Macaw Anodorhynchus Aureolarius. I have no reason to believe that they don't apply to this species.
It is probable that the Glaucous Macaw was a specialized feeder of palm nuts and also took other seeds, fruits and vegetable matter in smaller amounts. The diet of this species was likely heavily influenced by the clearing of forests to cultivate cattle and the cattle-ranching practices of early colonists, as well the yatay (Butia) palms from which it received much of its nutritional value.
In the wild it was commonplace to see the Glaucous macaw in savannahs and subtropical forests where palm trees were present. It was found 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 become fully full fledged. Both males and females are extremely dedicated to their offspring and will constantly hunt for food and shield them from predators.
Unfortunately, the Glaucous macaw is no longer present in the majority of its former habitat. The disappearance of this magnificent bird is likely due to continued trapping for the pet industry as well as disturbance of habitat, specifically the mass clearing of palm yatays which could have been their primary food source. The Glaucous macaw is listed under Critically Endangered.
Breeding
Glaucous macaws typically form long-term monogamous couples with both parents taking a role in raising the young. They breed in the dry season, when food is plentiful. Females lay a clutch of two to three eggs, which are incubated for around 28 days. When the chicks are born, they are fed by their parents through regurgitation for the first few weeks of their lives. The young macaws begin to explore and to feed themselves. They are also taught how to fly and forage.
The glaucous Macaw is highly social bird. They are active during the day and spend their nights resting. They will often seek shelter in tree cavities or other suitable nesting sites for the night. Their calls can be heard in the forest throughout the day.
While it is hoped that the species will recover from its decline in the wild, the bird faces many threats, including loss of habitat and illegal trapping for pet trade and deforestation. It is estimated that there are less than 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 Blue-throated Hummingbird is distinguished by its bright blue feathers. It is a large bird, measuring 70 centimeters long and has a sturdy beak that can crack open hard nuts and seeds. This beautiful bird is native to South America, and it is found in a variety of habitats, including forests, dry lowland grasslands, and wetland.
This magnificent bird is a sign of South American biodiversity. Its appearance is elegant, with its slender body, light build and vivid blue feathers. The black and curly beak helps it crack open seeds and nuts, which are exotic bird purchase a large part of its diet. It is a great-looking bird, and it's often seen in shows featuring birds. It is also popular in captivity, where it can live a lifetime.
