Glaucous Macaw
The glaucous macaw is one of the world's rarest birds. It is Critically Endangered, and may be extinct in the wild.
The bird has been reported by aviculturists in various countries, but the latest sighting was reported in 1992. The reported 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 magnificent bird is characterized by the blue feather pattern and a powerful beak that is capable of breaking open nuts and seeds. Glaucous Macaws form monogamous long-term couples, and both parents raise the chicks. The chicks are fed regurgitated food during the first few weeks of life before being fed solid food as the chicks grow. Parents also play a vital role in teaching the young macaws how to fly and hunt.
The glaucous Macaw has gone extinct, yet rumors of its existence persist across the globe. It is estimated that the glaucous Macaw was extinct in the 1800s because of cattle grazing and logging in yatay palm (Butia yatay) trees, where these birds primarily gathered their meals. The Glaucous Macaw is believed have returned, and is often kept along with its larger relative, Lear’s macaw.
In terms of habitat The glaucous macaw is able to be found in subtropical forests of South America. They are usually located in areas with a lot of palm trees, and they are known to be highly adaptable to a variety of forested habitats. These beautiful birds can be territorial and will defend the feeding and nesting area from intruders.
There have been a lot of reports on the glaucous macaw through the years, but many 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 a completely absurd claim until it is verified by hard evidence. Many experts have concluded that this bird is likely to be extinct since there are no records from the last century. However they have been willing to accept a slim chance of its survival. If it survives it is highly unlikely to make it to huge numbers.
Habitat
The macaw with the glaucous is a striking bird, renowned for its large size and striking 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, which is predominantly black, has a distinct shape that allows it to break seeds and nuts. They form a large portion of its diet.
The Glaucous Macaw is considered Critically Endangered by the IUCN which states that it has an extremely small population and is at a high chance of becoming extinct. This species was formerly fairly widespread but now it is found in northern Argentina as well as southern Paraguay, north-eastern Uruguay and Brazil from Parana state southwards where it was a nesting place in cliffs along major rivers.
Although there haven't been any confirmed sightings of this species since 1830 however, the Glaucous Macaw seemed not to be very rare in its limited range. specimens were captured up to 1850 (in Corrientes). The last living Glaucous Macaw believed to originate from Brazil was seen in the Buenos Aires Zoo back in 1936.
The reassessment suggests that the species is a generalist and prefers the savanna habitat, which is which is surrounded by palm "islands" and bands of riparian forests along rivers. It was a specialist for the consumption of palm fruits especially those of the yatay (or chatay) palm (Butia). However, it also ate ripe or unripe fruits as well as berries, nuts and even vegetable matter. It nestled on steep slopes and in cliffs, sometimes in tree cavities and laid an average clutch of two eggs.
This bird was likely to be gregarious and social, similar to other parrots. It could live for up to 14.8 years in captivity. It was said to be a reliable breeder that reproduced year after year. In the wild, its lifespan was probably between 50 and 80 years. This species was a potent disperser of seeds, and could have contributed towards the success of the palm yatay in its natural habitats.
Feeding
The Glaucous Macaw (Anodorhynchus glaucus) is one of the most stunning of the parrot species and its presence has an enormous impact on its environment. This massive South American parrot is known for its bright blue feathers, bright yellow eyes and the teardrop-shaped lappet on its lower beak.
In the past, little was known about feeding habits of the Glaucous Macaw. The earliest detailed references that I have located are two works by H.W. Bates, "The Naturalist on the Amazons" first published in 1863 about his 11 year sojourn in Brazil and later in his book "As Birds of the Brazilian Forests". Both of these refer to the Hyacinthine Macaw (Anodorhynchus aureolarius) However, I have no reason to believe that they're not applicable to this species.
It is probable that the Glaucous Macaw was a particular feeder of palm nuts and also consumed other seeds, fruits and vegetable matter in smaller amounts. The diet of this species is likely to have been influenced by the clearance of forests by early colonists for agriculture 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 in the wild, the Glaucous Macaw was often found in subtropical forests that had cliffs and savannahs with palm trees, where it nestled in tree cavities and 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 rely on their parents for care until they can fly and fully fledged. Both the males and females are committed to their offspring and will hunt for food and protect them from predators.
Unfortunately unfortunately, the Glaucous Macaw has been eradicated from the majority of its former range. The disappearance of this majestic bird is likely due to the continued trapping of pets for the pet trade, as well as disturbance of habitat, especially the massive removal of yatay palms where it could have gotten its main food supply. The Glaucous macaw is listed under Critically Endangered.
Breeding
Glaucous macaws typically form long-term monogamous pairs and both parents play part in raising the young. They breed during the dry season, when the food supply is at its highest. The female will lay two to three eggs which are incubated by the mother for about 28 days. Once the chicks hatch they are fed by their parents through regurgitation during the first few weeks of their life. The macaws' young begin to explore their surroundings and learn to eat themselves. They are also taught how to fly and forage.
Like all birds, glaucous Macaws are extremely social creatures. They are active during the day but spend their nights resting. They usually seek shelter in tree cavities or here other nesting spots for the night. Their calls can be heard throughout the forest throughout the day.
The species is expected to rebound from its decline, however it is facing numerous threats, including habitat loss illegal trapping of the bird to sell on the pet 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 called the Lear's macaw, or the blue-throated hummingbird, and is distinguished by its vibrant blue feathers. It is a large parrot measuring 70 centimeters in length and features a robust beak that is able to break open tough nuts and seeds. This beautiful bird is native to South America, and it is found in a variety of habitats such as grasslands, forests, dry lowland, and wetland.
This magnificent bird is an emblem of South American biodiversity. Its elegant appearance is reflected with its slender body, bright blue feathers and its light build. Its black and curved beak makes it easier to crack open nuts and seeds, which make up a significant part of its diet. It is a great-looking bird, and is often featured in bird shows. It is also popular in captivity, where it can live a lifetime.
