Glaucous Macaw
The glaucous Macaw is one of the rarest birds on earth. It is critically endangered and could even be extinct.
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 male.
Origin
The Glaucous macaw is an endangered parrot species that is native to South America. This magnificent bird features a distinctive blue feather pattern and a strong beak that is capable of breaking open hard nuts and seeds. Glaucous Macaws form monogamous long-term pair and both parents care for the chicks. The chicks are fed a diet of regurgitated food in the first few weeks of life, and then solid foods as the chicks develop. Parents play a vital role in teaching young macaws to fly and hunt.
The glaucous Macaw is extinct, yet rumors of its existence continue to circulate around the world. The Glaucous Macaw is believed be extinct by the 1800s due to cattle grazing on yatay (Butia) palm groves from which the birds would gather their food. The glaucous Macaw is believed to be making a comeback and is often kept along with its larger cousin, Lear's macaw.
The glaucous Macaw can be found in sub-tropical rainforests in South America. They are usually found in areas with abundant palm trees, and they are believed to be extremely adaptable to different types of forested habitats. These beautiful birds are also recognized as being very territorial and will defend their feeding and nesting areas from trespassers.
Over the years there have been numerous reports of the glaucous macaw, but they are generally considered unreliable. The most recent report of a wild occurrence involves an friend of Ridgely's that claimed to have observed four Glaucous macaws in Califomia. This claim is untrue until it is supported with evidence. Many experts have concluded that the bird is likely extinct because there are no records in the last century. However they have always been willing to accept a slim chance of its survival. If it is able to survive, it will be extremely uncommon to observe large numbers.
Habitat
The macaw with the glaucous is a striking bird, renowned for its large size and striking turquoise-blue coloring. The tail feathers and wings are long, enhancing its fluid and graceful movements. This bird is also a symbol of loyalty and love. Its beak, which is primarily black, has a distinct shape that allows it crack seeds and nuts. These are a large part its diet.
The Glaucous Macaw is considered Critically Endangered by the IUCN and the IUCN states that it has a small population and is at high chance of becoming extinct. The species was once widespread, but is now only found in northern Argentina, south Paraguay and north-eastern Uruguay, as well as Brazil, from Parana state to south, where it nests in cliffs alongside major rivers.
The Glaucous Macaw was not rare in its limited area, despite the fact that there were no reliable sightings after 1830. Specimens were collected until 1860 (in Corrientes). The last living Glaucous Macaw believed to originate from Brazil was seen in the Buenos Aires Zoo back in 1936.
The reassessment suggests that the species is a generalist, preferring the savanna habitat, which is which is surrounded by palm "islands" and riparian forest bands along river systems. It was a specialized for the consumption of palm fruits especially those of the yatay (or chatay) palm (Butia). However, it also ate ripe or unripe fruits and berries, nuts, and even vegetable matter. It nests on steep slopes on cliffs, in cliffs, and occasionally in tree cavities.
As with other parrots this bird was social, and was likely to be 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 year. In the wild, the lifespan was probably between 50 and 80 years. This species was a powerful seed disperser and could 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 an immense impact in its surroundings. This huge South American parrot is known for its vibrant blue feathers, bright yellow eyes and the teardrop-shaped lappet on its lower beak.
As of the time of writing, little was known about food habits and diet of the Glaucous macaw. The first detailed references I have located are two works by H.W. Bates, "The Naturalist on the Amazons" first published in 1863 about his 11 year stay in Brazil and later in his book "As Birds of the Brazilian Forests". Both are about the Hyacinthine Macaw, Anodorhynchus Aureolarius. I have no reason to believe that they don't apply to this species.
The Glaucous macaw is likely to be a specialized eater, consuming only palm nuts however, there were also tiny amounts of other fruits, seeds and vegetable matter. The diet of this species is likely to be influenced by the clearance of forests by early colonists for agriculture and cattle ranching and the removal of the yatay palm (Butia yatay) from which it may have gotten a lot of its nutrition.
In the wild the Glaucous Macaw was often found in subtropical forests that had cliffs and savannahs with palm trees where it nested in tree cavities, on rocky banks or the top of palm fronds. On average two clutches of eggs was laid and then incubated by the female.
The young Glaucous Macaws rely on their parents for their care until they can fly and fully grown. Both males and females are dedicated to their offspring, and hunt for food and protect them against predators.
Unfortunately, the Glaucous macaw is no longer found in most of its former habitat. The disappearance of this magnificent bird is likely due to continued check here trapping for the pet industry as well as habitat disruption, especially the massive removal of palm yatays that may have been its primary food source. The Glaucous macaw is classified as Critically Endangered.
Breeding
Glaucous macaws usually form long-term monogamous pairs and both parents play part in raising the young. They breed during the dry season, which is when food is most abundant. The female will lay up to three eggs, which are incubated by the mother for about 28 days. For the first few weeks following hatching, the chicks are fed by their parents through regurgitation. The macaws' young begin to explore their surroundings and learn to eat themselves. They also learn to fly and hunt for food.
The glaucous Macaw is a extremely social bird. They are active during the day but are restful at night. They will often 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.
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. Only about 20 glaucous Macaws are estimated to be living in the wild. The IUCN classifies the bird as "Critically Endangered--Possibly Extinct."
The glaucous Macaw is known as the Lear's macaw, or the blue-throated hummingbird. It is distinguished by its vibrant blue feathers. The parrot measures 70 centimeters long and features a an impressive beak that is capable of slicing open seeds and nuts. This beautiful bird is native to South America, and it can be found in many habitats like forests, dry lowland grasslands and wetlands.
This magnificent bird is a sign of South American biodiversity. Its appearance is elegant with its slim build, lightweight body, 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's a beautiful bird, and is often seen in bird shows. It is also popular in captivity, where it can live for a long time.
