Glaucous Macaw
The glaucous macaw is considered to be one of the world's rarest birds. It is considered Critically Endangered and could become extinct in the wild.
The bird has been observed by aviculturists from various countries, but the latest sighting was recorded 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 parrot native to South America. It is threatened. This majestic bird is distinguished by the blue feather pattern and a sharp beak that can break open nuts and seeds. Glaucous Macaws form monogamous long-term couples, and both parents raise the chicks. The chicks are fed regular food in the first few weeks of life before being fed solid food as the chicks develop. Parents are also responsible for teaching young macaws to fly and hunt.
The glaucous Macaw is extinct, yet rumors of its existence continue to circulate across the globe. It is believed that the glaucous macaw extirpated in the 1800s because of the logging industry and cattle grazing in yatay palm (Butia yatay) trees, where these birds primarily gathered their meals. The glaucous Macaw is believed to have returned, and is usually kept with its larger mate, Lear's macaw.
The glaucous Macaw lives in subtropical rainforests of South America. They are usually found in areas with abundant palm trees, and they are known to be highly adaptable to various types of forested 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 number of reports about the glaucous macaw through the years, but many are considered to be not reliable. The most recent wild claim was made by an avicultural acquaintance of Ridgely who claimed to have seen four Glaucous Macaws in Califomia. This is a completely absurd claim until it is confirmed with hard evidence. The lack of any acceptable data on this bird over the last century has caused many experts to believe that it is extinct, however they have always been willing to accept an extremely remote possibility of its existence (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it does survive, it will be extremely rare to witness large numbers.
Habitat
The Glaucous Macaw is a magnificent bird, well-known for its size and turquoise-blue coloring. Its long tail and wings highlight its graceful and agile movement. The bird is also an emblem of love and loyalty. Its beak, which is predominantly black, is distinctive in its shape and allows it to break seeds and nuts. These are a large part of its diet.
The Glaucous Macaw is considered Critically Endangered by the IUCN which states that it has a small population and is at a high chance of becoming extinct. The species was once widespread however, it is now found in northern Argentina south Paraguay and north-eastern Uruguay, as well as Brazil from Parana state to south, where it resides in cliffs alongside major rivers.
The Glaucous Macaw was not rare in its limited range, even though there was no evidence of sightings after 1830. The specimens were taken up 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 have come from Brazil.
The reassessment suggests that the species is a generalist and prefers areas of savanna that are that is interspersed with palm "islands" and bands of riparian forests along rivers. It was a specific feeder of palm fruits, especially those of the chatay palm (Butia yatay) but it was also likely to consume ripe and unripe fruit as well as berries, nuts and vegetables. 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 said that it could live up to 14.4 years in captivity, and was a reliable breeder who reproduced year after year. In the wild, its lifespan was likely to be between 50 and 80 years. This species was a powerful seed disperser and may have contributed to the success of the yatay palm in its native habitats.
Feeding
The Glaucous Macaw is one of the most stunning parrots. Its presence has a strong impact on its environment. This large South American parrot is known for its bright blue feathers, yellow eyes and the teardrop-shaped lappet on the lower portion of its beak.
As of the time of writing, little was known about feeding habits and diet of the Glaucous macaw. The first references to the subject I have found are in two publications 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 these references to the Hyacinthine Macaw (Anodorhynchus aureolarius) however I see no reason to believe that they are not applicable to this species.
It is probable that the Glaucous Macaw was a specialist in the consumption of palm nuts, and also took other seeds, fruits and vegetable matter in small quantities. This species' diet was likely heavily influenced by the clearing of forests to cultivate cattle and the cattle-ranching practices of early colonists as well as the yatay (Butia) palms from which it got a large portion of its nutrition.
In the wild it was commonplace to find the Glaucous macaw in subtropical forests and savannahs where palm trees were found. It hid in tree cavities or on rocky banks and palm fronds. On average two eggs were laid in a clutch. eggs was laid and incubated by the female.
The young Glaucous Macaws rely on their parents for their care until they can fly and are fully full fledged. Both males and females are very dedicated to their offspring, and hunt for food and protect them from predators.
Unfortunately, the Glaucous Macaw has been extirpated from its entire former range. The disappearance of this majestic bird is likely due to the continued trapping for the pet trade, as well as disturbance to habitat, specifically the mass clearing of yatay palms from where it could have gotten its primary food source. The Glaucous macaw is classified as Critically Endangered.
Breeding
Glaucous Macaws form monogamous long-term pairs. Both parents are involved in raising their young. They breed during the dry season, which is 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. In the initial few weeks after hatching, the chicks are fed daily by their parents via regurgitation. The young macaws begin to explore and learn to feed themselves. They are also taught to fly and forage.
visit this backlink can be described as a very social bird. They are active during the day and spend their nights resting. In the evening, they will often seek refuge inside tree cavities or other nesting areas that are suitable. They are highly 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 is facing numerous threats, such as the loss of habitat illegal trapping for the pet trade and deforestation. It is believed 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 sometimes referred to as Lear's Macaw or blue-throated Hummingbird is distinguished by its vibrantly 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 gorgeous bird is native to South America, and it is found in various habitats like grasslands, forests, dry lowland and wetland.
This majestic bird is an emblem of South American biodiversity. Its elegant appearance with its slim body, light build, and vibrant blue feathers. Its beak is curved and black, which helps it open the nuts and seeds which comprise a significant portion of its diet. It's a beautiful bird, and is often used in shows featuring birds. It is also popular in captivity where it can live a lifetime.
