Glaucous Macaw
The glaucous Macaw is among the rarest birds in the world. It is in danger of disappearing and may even be extinct.
This bird has been reported by aviculturists in various countries, but the latest sighting was in 1992. This alleged sighting occurred in southwestern Paraguay close to the city of Corrientes. The bird was male.
Origin
The Glaucous macaw is a threatened parrot species that is native to South America. This majestic bird is distinguished by its unique blue feather pattern and strong beak that is capable of breaking open hard nuts and seeds. Glaucous macaws are known to form long-term monogamous couples and both parents are involved in the raising of the chicks. The chicks are fed a diet of regurgitated food during the first few weeks of their lives and then a variety of solid foods as the chicks develop. 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 all over the world. The glaucous
Blondie scarlet macaw bird is believed to have gone extinct in the 1800s due to the logging industry and cattle grazing in yatay (Butia) palm groves from which the birds gathered their food. The glaucous Macaw is believed to have returned, and is often kept with its larger cousin, Lear's
Ziggy Our Scarlet Macaw.
In terms of habitat, the glaucous macaw can be found in the sub-tropical forests of South America. They are typically found in areas that have plenty of palm trees, and are thought to be extremely adaptable to a variety of forested habitats. These beautiful birds are also known to be extremely territorial and will defend their feeding and nesting areas from intruders.
There have been a number of reports involving the glaucous macaw through the years, but many are considered to be unreliable. The most recent report of a wild occurrence involves a friend of Ridgely's that claimed to have seen four Glaucous macaws in Califomia. This claim is unacceptable until it can backed up with hard evidence. The lack of any acceptable data on this bird over the past century has caused many experts to think that it's likely extinct, but they have always accepted an extremely remote possibility of its existence (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 glaucous macaw is a striking bird that is known for its size and stunning turquoise-blue coloring. The tail and wings are long, enhancing its graceful and agile movements. This bird is also an emblem of loyalty and love. Its beak, which is mostly black, has a distinctive shape and allows it to crack nuts and seeds. These are a large part its diet.
The Glaucous Macaw is considered Critically Endangered by the IUCN, which notes that it has an extremely small population and is at a high risk of extinction. The species was once widespread but is now found in northern Argentina, south Paraguay and north-eastern Uruguay and Brazil, from Parana state to the south, where it resides in cliffs that run alongside major rivers.
Although there have been no credible sightings of the species since 1830 The Glaucous Macaw seemed not to be a rare species in its limited range. 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 be from Brazil.
Reassessment suggests that this species is a generalist, and prefers the savanna habitat, which is that is interspersed with palm "islands", and bands of riparian forests along river systems. It was a specialist for the consumption of palm fruits, especially those of the yatay (or chatay) palm (Butia). However it also ate ripe and unripe fruits and berries, nuts, and even vegetable matter. It nests on steep slopes, in cliffs and sometimes 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 who reproduced year after year. The life expectancy of this species in the wild was perhaps 50-80 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 (Anodorhynchus glaucus) is among the most beautiful of the parrot species and its presence has a powerful impact in its surroundings. This massive South American bird is known for its vivid blue feathers and yellow eyes as well as the distinctive teardrop-shaped lappet that brackets the lower portion of its beak.
Up until recently, very little was known about 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" which was first published in 1863, and describes his 11-year journey in Brazil. Later in his book "As Birds of the Brazilian Forests" Bates wrote about the similar experience. Both of these are about 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 parrot cost was a specialized for the consumption of palm nuts. It also took other seeds, fruits, and vegetable matter in small amounts. The diet of this species is likely to be influenced by the clearance of forests by early colonists to cultivate and cattle ranching, as well as the felling of the yatay palm (Butia yatay) from which it could have received much of its nutrition.
In the wild the
Glaucous Macaw was commonly found in subtropical forests that had cliffs and savannahs with palm trees, where it nestled in tree cavities, on rocky banks or in the palm fronds' top. Females incubate and lay two eggs on average.
The young Glaucous Macaws are altricial, which means they depend on their parents to take care of them until they become fully grown and able to fly. Both males and females are committed to their offspring and hunt for food and defend them from predators.
Unfortunately, the Glaucous Macaw has been eradicated from the majority of its former range. The disappearance of this majestic bird is probably due to the ongoing trapping of pets for the pet trade as well as habitat disturbance, particularly the mass clearing of yatay palms from which it could have gotten its main food supply. The Glaucous Macaw is listed as Critically Endangered.
Breeding
Glaucous macaws typically form long-term monogamous pairs with both parents taking an active role in the raising of the young. They breed in the dry season, which is when food is plentiful. The female lays two to three eggs that are incubated by the mother for approximately 28 days. Once the chicks hatch they are fed by their parents via regurgitation during the first few weeks of life. The young macaws then begin to explore their surroundings and begin to learn to eat themselves. They also learn to fly and hunt for food.
Like all birds, glaucous macaws are highly social creatures. They are active during the day, but spend their nights resting. They usually seek shelter in cavities in trees or other suitable nesting sites for the night. They are highly vocal, and their calls can be heard throughout the forest during the day.
While it is believed that the species will recover from its decline in the wild, the bird faces numerous threats, including the loss of habitat, illegal trapping for the pet trade and deforestation. It is estimated that there are just 20 glaucous macaws that are in the wild. The IUCN classifies the bird as "Critically Endangered--Possibly Extinct."
The glaucous macaw is also called the Lear's macaw, or the blue-throated hummingbird. It is distinguished by its vivid blue feathers. The parrot is 70 centimeters long and features a a powerful beak capable of cracking open seeds and nuts. This beautiful bird is native South America and can be found in diverse habitats, including grasslands, forests, and lowland wetlands.
This majestic bird is an emblem of South American biodiversity. Its elegant appearance, with its slender body, light weight, and vibrant blue feathers. The black and curly beak helps it crack open seeds and nuts which comprise a significant portion of its diet. It is a beautiful bird and is often used in birds shows. It is also popular in captivity, where it can live a lifetime.
