Glaucous Macaw
The glaucous Macaw is one of the world's rarest birds. It is Critically Endangered and could be extinct in the wild.
Various aviculturalists have reported sightings of this bird however the most recent sighting was in 1992. The alleged sighting was reported to have occurred in the southwestern region of Paraguay, near the city of Corrientes. The bird was a male.
Origin
The Glaucous macaw is a threatened parrot species native to South America. This magnificent bird features a distinctive blue feather pattern as well as a powerful beak that is capable of cracking open tough nuts and seeds. Glaucous Macaws form monogamous long-term couples and both parents tend the chicks. The chicks are fed a diet of regurgitated food during the first few weeks of their lives, and then solid foods as they grow. Parents are also responsible for teaching the young macaws to fly and hunt.
The glaucous macaw is believed to be extinct in the wild, yet stories of this gorgeous bird's existence continue to spread across the globe. The glaucous Macaw is believed to be extinct by the 1800s due to cattle grazing on yatay (Butia) palm groves where the birds would gather their food. It is currently believed that the glaucous macaw made a comeback in captivity, where it is often kept with its larger cousin Lear's macaw.
In terms of habitat, the glaucous macaw can be found in the sub-tropical forests of South America. They are usually located in areas that have numerous palm trees. They are also highly adaptable to a variety of forested environments. These beautiful birds are also known to be extremely territorial and will protect their nesting and feeding areas from trespassers.
Over the years there have been numerous reports of the glaucous macaw However, they are generally considered unreliable. The most recent claim of a wild occurrence involves a friend of Ridgely's who claimed to have witnessed four Glaucous macaws in Califomia. This is a ridiculous claim until it is supported by solid evidence. The absence of any reliable data on this bird over the last century has caused many experts to think that it's likely extinct, but they have always been willing to accept a remote possibility of its existence (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it survives it will be extremely uncommon to observe large numbers.
Habitat
The glaucous Macaw is an impressive bird, renowned for its size and turquoise-blue coloring. Its wings and tail feathers are long, enhancing its fluid and graceful movements. The bird is also an emblem of love and loyalty. Its beak is predominantly black, and it is distinctive in its shape. It allows it to break open nuts and seeds, which make up a large part of its diet.
IUCN has classified the Glaucous Macaw as Critically Endangered. It notes that there is a small population of this bird and it is in risk of extinction. This species was once widespread, but is now only found in northern Argentina south Paraguay and north-eastern Uruguay and Brazil and Brazil from Parana state to the south, where it nests in cliffs alongside major rivers.
The Glaucous Macaw was not rare in its relatively small area, even though there were no reliable sightings since 1830. Specimens were collected up until 1850 (in Corrientes). The last known living Glaucous Macaw was seen at the Buenos Aires Zoo in 1936 and is believed to have come from Brazil.
Reassessment suggests that this species is a generalist, preferring savanna habitat that is interspersed with palm "islands" and bands of riparian forests along river systems. It was a particular feeder of palm fruit especially those of the yatay (or chatay) palm (Butia). However, it also ate ripe or unripe fruits, nuts, berries, and vegetable matter. It nests on slopes that are steep or in cliffs, and also in tree cavities.
As with other parrots this bird was social and probably gregarious. It was said that it could live for up to 14.4 years in captivity, and was a reliable breeder that reproduced year after. In the wild, its life expectancy was likely to be between 50 and 80 years. This species was a powerful disperser of seeds and could have contributed to the success of the palm yatay species in its natural habitat.
Feeding
The Glaucous Macaw (Anodorhynchus glaucus) is among the most beautiful of the parrot species and has a an immense impact in its environment. This massive South American parrot is known for its bright blue feathers, yellow eyes, and the teardrop-shaped lipped on its lower beak.
Up until recently, very little was known about the eating habits and diet of the Glaucous macaw. The first detailed references I have located are two works by H.W. Bates' "The Naturalist on Amazons" which was first published in 1863, describes his 11-year sojourn in Brazil. Later, in his book "As Birds of the Brazilian Forests" Bates wrote about the same experience. Both of these are about the Hyacinthine Macaw (Anodorhynchus aureolarius), but I have no reason to believe that they are not applicable to this species.
It is likely that the Glaucous Macaw was a specialized in the consumption of palm nuts, and also ate other seeds, fruits and vegetable matter in smaller amounts. This species' diet was likely heavily influenced by the clearing of forests for agriculture and cattle-ranching by early colonists as well as the yatay (Butia) palms from which it received much of its nutrition.
In the wild in the wild, the Glaucous Macaw was found in subtropical forests that had the savannahs and cliffs surrounded by palm trees, where it nestled in tree cavities and on rocky banks or the palm fronds' top. The female incubates and lays two eggs per.
The young Glaucous Macaws rely on their parents to provide care until they fly and become fully fledged. Both males and females are extremely committed to their offspring and constantly hunt for food and shield them from predators.
Unfortunately the Glaucous macaw has been found in most of its former habitat. The disappearance of this magnificent bird is likely due to the ongoing trapping of pets for the pet trade and habitat disturbance, particularly the mass clearing of yatay palms from which it may have obtained its primary food source. The Glaucous Macaw is classified as Critically Endangered.
Breeding
Glaucous Macaws are monogamous, long-term pair. Both parents are involved in the raising of their young. They breed during the dry season, when the food supply is at its highest. The female read more will lay up to three eggs, which are incubated by the mother for around 28 days. In the initial few weeks after hatching the chicks are fed by their parents via regurgitation. The young macaws then begin to explore and to feed themselves. They are also taught how to fly and hunt for food.
The glaucous Macaw is a very social bird. They are active during daylight hours, and take a break at night. In the evening, they will often seek refuge in tree cavities or other nesting spots that are suitable. They are highly vocal, and their calls can be heard throughout the forest during the day.
While it is believed that 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 and illegal trapping for pet trade, and deforestation. It is estimated that there are less than 20 glaucous macaws that are in the wild. The IUCN classifies 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 has a sturdy beak that is able to break open tough nuts and seeds. The beautiful bird is native to South America and can be found in a variety of habitats, including grasslands, lowland forests and wetlands.
This magnificent bird is a sign of South American biodiversity. Its appearance is elegant with its slim body, light weight and vivid blue feathers. The black and curly beak helps it crack open seeds and nuts, which make up a significant part of its diet. It is a great-looking bird, and it's often used in shows featuring birds. It is also a popular bird in captivity, where it can be kept for a lifetime.
