Glaucous Macaw
The glaucous Macaw can be described as one of the rarest birds in the world. It is considered Critically Endangered and could be extinct in the wild.
The bird has been reported by aviculturists from various countries however the most recent sighting was reported in 1992. The alleged sighting was reported to have occurred in southwestern Paraguay close to the city of Corrientes. The bird was a male.
Origin
The Glaucous Macaw is a species of parrot native to South America. It is threatened. This majestic bird is distinguished by the blue feather pattern and a strong beak capable of cracking open seeds and nuts. Glaucous Macaws live in monogamous couples, and both parents raise the chicks. They feed their chicks regurgitated food for the first couple of weeks after birth, and later they begin eating solid foods as they grow. The parents also play a crucial role in teaching the young macaws how to fly and hunt.
The glaucous Macaw is extinct, yet rumors of its existence continue to spread all over the world. It is believed that the glaucous macaw was extinct in the 1800s due to cattle grazing and logging in yatay palm (Butia yatay) trees, where these birds typically gathered their food. It is currently believed that the glaucous macaw returned to captivity, where it is often kept alongside its larger cousin Lear's macaw.
In terms of habitat The glaucous macaw is able to be found in sub-tropical forests of South America. They are usually found in areas with abundant palm trees, and are thought to be extremely adaptable to different types of forested habitats. These beautiful birds can be territorial and will defend the nesting and feeding area from intruders.
There have been a number of reports on the glaucous macaw throughout the years, but most are considered to be unreliable. The most recent report of a wild occurrence involves an friend of Ridgely's that claimed to have witnessed four Glaucous macaws in Califomia. This is a ridiculous claim until it is supported by solid evidence. The lack of any acceptable data on this bird over the past century has been a reason for many experts to believe that it is extinct, but they have always been willing to accept a remote possibility of its survival (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it survives it is highly unlikely to reach large numbers.
Habitat
The Glaucous Macaw is a magnificent bird, renowned for its large size and turquoise-blue coloration. Its wings and tail feathers are long, enhancing its graceful and agile moves. This bird is an emblem of loyalty and love. Its beak is predominantly black and has a unique shape that allows it to break open seeds and nuts which comprise a large part of its diet.
IUCN has classified the Glaucous Macaw as Critically Endangered. It says that there is a tiny population of this bird and it is at risk of extinction. 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 is nestled in cliffs alongside major rivers.
Although there have been no credible sightings of the species since 1830 The Glaucous Macaw seemed not to be extremely rare within its comparatively small range; specimens were collected up to 1850 (in Corrientes). The last living Glaucous Macaw, believed to be from Brazil was displayed in the Buenos Aires Zoo back in 1936.
Reassessment suggests that this species is a generalist, and prefers savanna habitat that is interspersed with palm "islands", and bands of riparian forests along river systems. It was a specialised eater of palm fruits, specifically those of the chatay or yatay palm (Butia yatay) however, it could also feed on ripe and unripe fruit as well as berries, nuts and vegetables. It nestled on slopes and in cliffs sometimes in tree cavities and laid an average clutch of two eggs.
Like all parrots, this bird was social and was probably gregarious. It could live up to 14.8 years in captivity and was said to be a reliable breeder that reproduced year after year. Its life expectancy in the wild was 50-80 years. This species was a powerful seed disperser, and could have contributed to the success of the yatay palm 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 bird is known for its vibrant blue feathers and yellow eyes as well as its distinctive teardrop-shaped lappet that brackets the lower part of its beak.
Up until recently, very little was known about the eating habits and diet of the Glaucous macaw. The first detailed references I have found are two works by H.W. Bates' "The Naturalist on the amazons" which was first published in 1863, and describes his 11-year sojourn in Brazil. Later in his book "As Birds of the Brazilian Forests" He wrote about the more info similar experience. Both are about the Hyacinthine Macaw, Anodorhynchus Aureolarius. I have no reason to think that they could not apply to this species.
It is probable that the Glaucous Macaw was a specialist in the consumption of palm nuts, and also consumed other seeds, fruits and vegetable matter in small amounts. The diet of this species was likely influenced by the clearing of forests for farming and cattle-ranching by early colonists, as well the removal of yatay (Butia) palms from which it derived a lot of its nutritional value.
In the wild in the wild, the Glaucous Macaw was commonly found in subtropical forests with the savannahs and cliffs surrounded by palm trees, where it nested in tree cavities and on rocky banks or the palm fronds' top. On average two clutches of eggs was laid and then incubated by the female.
The young Glaucous Macaws are altricial, which means they depend on their parents to care for them until they become fully fledged and can fly. Both males and females are committed to their offspring and hunt for food and protect them from predators.
Unfortunately unfortunately, the Glaucous macaw is no longer present in the majority of its former habitat. The disappearance of the magnificent bird is likely to be due to continued trapping for the pet industry as well as habitat disruption, especially the mass removal of palm yatays that may have been its main food source. The Glaucous macaw is classified as Critically Endangered.
Breeding
Glaucous macaws typically form long-term monogamous couples and both parents play part in raising the young. They breed in the dry season, when food is most abundant. The female lays a clutch of two to three eggs, which are incubated for a period of around 28 days. In the initial few weeks after hatching, the chicks are fed by the parents via regurgitation. The young macaws then begin to explore their surroundings and begin to learn to feed themselves. They also learn how to fly and hunt for food.
Like all birds, glaucous macaws are highly social creatures. They are active during the day and are restful at night. During the night they usually seek shelter inside tree cavities or other suitable nesting places. Their calls can be heard in the forest throughout the day.
While it is believed that the species will be able to recover from its decline in the wild, the bird faces numerous threats, including the 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 called the Lear's macaw or the blue-throated hummingbird, and is distinguished by its vivid blue feathers. The parrot measures 70 centimeters long and features a powerful beaks that are capable of cracking open seeds and nuts. The beautiful bird is native to South America and can be found in various habitats that include forests, lowland grasslands and wetlands.
This majestic bird is an emblem of South American biodiversity. It has a regal appearance, with its slender body, light weight and bright blue feathers. Its beak is curved and black, which aids it open the nuts and seeds which comprise a significant portion of its diet. It is a stunning bird that is often seen in birds shows. It is also popular in captivity, where it can live for a long time.
