Glaucous Macaw
The glaucous Macaw is among the rarest birds in the world. It is Critically Endangered and could become extinct in the wild.
Various birdwatchers have reported sightings this bird, but the most recent was in 1992. The reported sighting was in the southwestern region of Paraguay, near the city of Corrientes. The bird was male.
Origin
The Glaucous Macaw is a species of parrot native to South America. It is endangered. This majestic bird is distinguished by the blue feather pattern and a strong beak that can break open seeds and nuts. Glaucous macaws form long-term monogamous families and both parents assist in raising the chicks. The chicks are fed regurgitated food in the first few weeks of life before being fed solid food as the chicks grow. Parents are also responsible for teaching young macaws to fly and hunt.
The glaucous macaw is considered to be extinct in the wild, but rumors of this beautiful bird's existence are still spreading throughout the world. The glaucous Macaw is believed to have gone extinct in the 1800s because of logging and cattle grazing on yatay (Butia) palm groves where the birds gathered their food. It is currently believed that the glaucous macaw has made a comeback in captivity and is usually kept alongside its larger cousin Lear's macaw.
In terms of habitat the glaucous macaw can be found in sub-tropical forests of South America. They are most often found in areas that have plenty of palm trees, and are believed to be extremely adaptable to different types of forested habitats. These beautiful birds can be territorial and defend the nesting and feeding area from intruders.
There have been a number of reports about the glaucous macaw throughout the years, but most are considered to be not reliable. The most recent claim of a wild occurrence involves a avicultural acquaintance of Ridgely's who claimed to have witnessed four Glaucous macaws in Califomia. This claim is untrue until it is supported with evidence. The lack of any acceptable evidence of this bird in the past century has led many experts to think that it's likely extinct, but they have always accepted the possibility of survival (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it survives, it is extremely unlikely to make it to huge numbers.
Habitat
The macaw glaucous is an impressive bird that is known for its huge size and stunning turquoise-blue coloring. Its long tail and wings accentuate its graceful and agile movements. This bird is a symbol of loyalty and love. Its beak is predominantly black and is distinctive in its shape. It allows it to break open seeds and nuts, which comprise a large portion of its diet.
IUCN has classified the Glaucous Macaw as Critically Endangered. It says that there is only a small population of this bird and it is at the risk of becoming extinct. 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 the south, where it resides in cliffs alongside major rivers.
The Glaucous Macaw was not rare in its small range, despite the fact that there was no proof of sightings since 1830. There were specimens collected until 1850 (in Corrientes). The last living Glaucous Macaw believed to originate from Brazil was seen in the Buenos Aires Zoo back in 1936.
Re-evaluation of the historical records suggests that this species was rather generalist in its habitat preferences and preferred the savanna ecosystem, which was interspersed with palm "islands" and areas of riparian forest along rivers. 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 as well as berries, nuts and other vegetable matter. It is a nesting place on steep slopes, in cliffs and sometimes in tree cavities.
As with other parrots this bird was social, and was likely to be sociable. It was believed 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, its lifespan 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 habitats.
Feeding
The Glaucous Macaw is one of the most stunning parrots. Its presence has a strong influence on the surrounding. This huge South American parrot is known for its bright blue feathers, bright yellow eyes, and the teardrop-shaped lipped on its lower beak.
In the past, little was known about the feeding habits of the Glaucous Macaw. The earliest detailed references that I have found 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 work "As Birds of the Brazilian Forests". Both of these refer to the Hyacinthine Macaw (Anodorhynchus aureolarius) However, I have no reason to think that they are not applicable to this species.
It is likely that the Glaucous Macaw was a specialized feeder of palm nuts and also consumed other seeds, fruits, and vegetable matter in small quantities. The diet of this species was likely affected by the clearing of forests to cultivate cattle and the cattle-ranching practices of early colonists as well as the felling of yatay (Butia) palms from which it got a large portion of its nutrition.
In the wild it was commonplace to see the Glaucous macaw in savannahs and forests that were subtropical in which palm trees were present. It nestled in tree cavities or on rocky banks or palm fronds. On average two eggs were laid in a clutch. eggs was laid and incubated by the female.
The young Glaucous Macaws rely on their parents to provide care until they are able to fly and fully grown. Both females and males are extremely dedicated to their offspring and will tirelessly hunt for food and defend them from predators.
Unfortunately, the Glaucous macaw is no longer found in its former habitat. The disappearance of this majestic bird is probably due to the continuing trapping for the pet trade and disturbance to habitat, specifically the wholesale removal of yatay palms which it may have obtained its main food supply. The Glaucous Macaw is listed as Critically Endangered.
Breeding
Glaucous macaws usually form long-term monogamous pairs and both parents play an active role in the raising of the young. They breed during the dry season, when the availability of food is at its highest. The female will lay up to three eggs, which are incubated by the mother for approximately 28 days. After hatching they are fed by their parents through regurgitation for the first few weeks of their lives. The macaws' young begin to explore their surroundings and learn to eat themselves. They are also taught to fly and hunt for food.
Like all birds, glaucous macaws are extremely social creatures. They are active during the day but buy-macaw sleep at night. They usually seek shelter in cavities in trees or other nesting spots to sleep. They are very vocal and their calls can be heard throughout the forest during the day.
The species is expected to recover from the decline, but it is facing numerous threats, including habitat loss and illegal trapping of the bird for the pet market, and deforestation. It is believed that there are less than 20 glaucous macaws in the wild. The IUCN classifies the bird as "Critically Endangered, possibly extinct."
The glaucous macaw, 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 a powerful beak capable of breaking open seeds and nuts. This gorgeous bird is native to South America, and it is found in various habitats, including forests, dry lowland grasslands and wetland.
This majestic bird is a sign of South American biodiversity. Its appearance is elegant with its slim body, light build and vivid blue feathers. Its beak is curvaceous and black, which helps it crack open the nuts and seeds that comprise a large portion of its diet. It's a stunning bird, and is often seen in bird shows. It is also a favorite in captivity, where it can remain for a long time.
