Glaucous Macaw
The glaucous Macaw is among the rarest birds in the world. It is in danger of disappearing and may even be extinct.
Many birdwatchers have reported sightings this bird However, the most recent sighting was in 1992. The reported sighting was in the southwestern region of Paraguay close to the city of Corrientes. The bird was male.
Origin
The Glaucous macaw is an endangered 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 cracking open tough nuts and seeds. Glaucous Macaws form monogamous long-term pairs 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 the chicks grow. The parents also play a vital role in teaching young macaws to fly and hunt.
The glaucous Macaw is 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) groves, where these birds typically gathered their food. It is currently believed that the glaucous macaw returned to captivity in the wild, where it is 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 most often located in areas that have numerous palm trees. They are also extremely adaptable to different types of forest environments. These beautiful birds are known to be very territorial and will defend their nesting and feeding areas from intruders.
There have been a variety of reports involving the glaucous macaw throughout the years, but they are considered to be unreliable. 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 completely untrue until it can be verified with hard evidence. The absence of any reliable evidence of this bird in the past century has caused many experts to think that it's likely extinct, however they have always been willing to accept the possibility of survival (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it survives it will be very uncommon to witness large numbers.
Habitat
The macaw with the glaucous is a striking bird, renowned for its large size and dazzling turquoise-blue coloration. The long tail and wings enhance its graceful and agile movement. The bird is a symbol of loyalty and love. Its beak is mostly black, and it has a unique shape that allows it to crack open seeds and nuts, which constitute a significant portion of its diet.
The Glaucous Macaw is considered Critically Endangered by the IUCN and the IUCN states that it has an extremely small population and is at high chance of becoming extinct. This species was once widespread but is now found in northern Argentina, south Paraguay and north-eastern Uruguay, as well as Brazil and Brazil from Parana state to the south, where it nests 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 comparatively small range; specimens were collected from 1830 to 1860 (in Corrientes). The last living Glaucous Macaw believed to be from Brazil was seen in the Buenos Aires Zoo back in 1936.
The reassessment suggests that the species is a generalist, and prefers areas of savanna that are that is interspersed with palm "islands", and riparian forests along rivers. It was a specific food source for palm fruits, especially those of the chatay or yatay palm (Butia yatay), but it was likely to also consume ripe and unripe fruit as well as berries, nuts and vegetable matter. It nests on slopes that are steep on cliffs, in cliffs, and occasionally in tree cavities.
This bird was likely gregarious and social, similar to other parrots. It could live up to 14.8 years in captivity and was believed to be a reliable breeder that reproduced year after year. In the wild, its life expectancy was probably between 50 and 80 years. This species was a potent disperser of seeds and may have contributed towards the success of the palm yatay in its natural habitat.
Feeding
The Glaucous Macaw is one of the most stunning parrots. Its presence can have 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 which adorns the lower part of its beak.
As of the time of writing, little was known about the feeding habits and diet of the Glaucous macaw. The earliest detailed references I have found are in two publications by H.W. Bates, "The Naturalist on the Amazons" first published in 1863, detailing his 11-year stay in Brazil and later in his work "As Birds of the Brazilian Forests". 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.
The Glaucous macaw is likely to be a specialized eater, consuming only palm nuts as well as small amounts of other seeds, fruits and other matter. The diet of this species is likely to have been influenced by the clearance of forests by early colonists to cultivate and cattle ranching, as well as the removal of the yatay palm (Butia yatay) from which it could have gotten a lot of its nutrition.
In the wild, it was common to find the Glaucous macaw in savannahs and subtropical forests in which palm trees were present. It was found in tree cavities or on rocky banks or palm fronds. The female incubates and lays two eggs on average.
The young Glaucous Macaws are altricial, meaning they rely on their parents to care for them until they become fully grown and fly. Both females and males are extremely committed to their offspring and will continuously hunt for food and protect them from predators.
Unfortunately, the Glaucous macaw is no longer found in most of its former habitat. The disappearance of this majestic bird is probably due to the continuing trapping for the pet trade and disturbance of habitat, especially the massive clearing of yatay palms from Blondie scarlet macaw bird 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 couples and both parents play part in raising the young. They breed during the dry season, which is when the food supply is at its highest. The female lays an egg clutch that ranges from two to three eggs, which are incubated for about 28 days. For the first few weeks after hatching the chicks are fed daily by their parents through regurgitation. Then the young macaws begin to explore their surroundings and begin to learn to feed themselves. They also learn to fly and hunt for food.
Like all birds, glaucous macaws are highly social creatures. They are active during daylight hours, and rest at night. They usually seek shelter in cavities in trees or other suitable nesting places for the night. Their calls can be heard in the forest throughout the day.
The species is expected to recover from its decline, however it faces many threats including habitat loss and illegal trapping of the bird 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 also known as Lear's Macaw or Blue-throated Hummingbird is distinguished by its bright blue feathers. The parrot measures 70 centimeters long and has powerful beaks that are capable of slicing open seeds and nuts. This gorgeous bird is native to South America and can be found in diverse habitats such as 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 vibrant blue feathers. The black and curly beak allows it to break open seeds and nuts which comprise a significant portion of its diet. It is a stunning bird and is often used in bird shows. It is also popular in captivity, where it can live a lifetime.
