Glaucous Macaw
The glaucous Macaw is among the rarest birds in the world. It is considered Critically Endangered and could become extinct in the wild.
Many aviculturalists have reported sightings of this bird However, the most recent sighting was in 1992. The reported sighting was in the southwest 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 the blue feather pattern and a powerful beak that can break open seeds and nuts. Glaucous macaws have been known to form long-term monogamous couples and both parents assist in raising the chicks. They feed the chicks a diet of regurgitated food for the first few weeks after birth, and then they begin eating solid foods as they develop. The parents also are a key part of teaching young macaws to fly and forage.
The glaucous Macaw is extinct, yet rumors of its existence continue to circulate around the world. It is estimated that the glaucous macaw extirpated in the 1800s due to cattle grazing and logging in yatay palm (Butia yatay) groves, where these birds typically gathered their food. The Glaucous Macaw is believed have returned, and is often kept along with its larger relative, Lear’s macaw.
The glaucous Macaw lives in sub-tropical rainforests of South America. They are usually found in areas where there are numerous palm trees. They are also highly adaptable to a variety of forest habitats. These beautiful birds can be territorial and will protect the feeding and nesting area from intruders.
In the past, there have been numerous reports on the glaucous Macaw However, they are generally not considered reliable. The most recent wild claim was made by an avicultural friend of Ridgely who claimed to have spotted four Glaucous Macaws in Califomia. This claim is completely unacceptable until it can be verified with solid evidence. The absence of any reliable evidence of this bird in the last century has been a reason for many experts to think that it's likely extinct, however they have always been willing to accept an extremely remote possibility of its survival (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it does survive it will be extremely uncommon to observe large numbers.
Habitat
The macaw glaucous is an impressive bird that is known for its huge size and dazzling turquoise-blue coloration. The long tail and wings enhance its graceful and agile moves. This bird is also an emblem of loyalty and love. Its beak, which is predominantly black, has a distinctive shape that allows it to crack nuts and seeds. These are a large part of its diet.
The Glaucous Macaw is considered Critically Endangered by the IUCN, which notes that it has a small population and is at a high danger of disappearing. The species was previously fairly widespread but now it is only found in northern Argentina, southern Paraguay and north-eastern Uruguay and Brazil from Parana state southwards. It nestted in cliffs along major rivers.
While there have been no credible sightings of the species since 1830, the Glaucous Macaw seemed not to be extremely rare within its relatively limited range; specimens were collected from 1830 to 1860 (in Corrientes). The last living Glaucous Macaw, believed to be from Brazil, was exhibited in the Buenos Aires Zoo back in 1936.
Re-evaluation of the historical documents suggests that this species was a very generalist in its habitat preferences, with a preference for areas of savanna that were interspersed with palm "islands" and forests of riparian along river systems. It was a specialist for the consumption of palm fruits particularly those of the yatay (or Melody blue spix macaw chatay) palm (Butia). However, it also ate ripe or unripe fruits, nuts, berries, and other vegetable matter. It nested on steep slopes and cliffs, occasionally in tree cavities and laid an average clutch of two eggs.
Like other parrots, this bird was social and was probably gregarious. It was reported that it could live for up to 14.4 years in captivity and was a reliable breeder who reproduced year after. In the wild, the lifespan was probably between 50 and 80 years. This species was a potent seed disperser, and could have contributed to the success of the yatay palm in its natural habitats.
Feeding
The Glaucous Macaw is one of the most stunning parrots. The presence of this parrot has a strong influence on the surrounding. This large South American parrot is known for its vibrant blue feathers, yellow eyes, and the teardrop-shaped lipped on the lower portion of its beak.
In the past, little was known about the feeding habits and diet of the Glaucous macaw. The first 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 sojourn in Brazil and later in his work "As Birds of the Brazilian Forests". Both of these refer to 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 particular feeder of palm nuts and also took other seeds, fruits, and vegetable matter in smaller quantities. The diet of this species was likely heavily influenced by the clearing of forests for agriculture and cattle-ranching by early colonists as well as the removal of yatay (Butia) palms from which it received much of its nutrition.
In the wild, it was common to see the Glaucous macaw in subtropical forests and savannahs where palm trees were found. It nestled in tree cavities, or on rocky banks and palm fronds. Females incubate and lay two eggs on average.
The young Glaucous Macaws rely on their parents for care until they can fly and are fully grown. Both males and females are very committed to their offspring and will hunt for food and protect them from predators.
Unfortunately, the Glaucous Macaw has been eliminated from the majority of its previous range. The disappearance of this majestic bird is likely due to the continued trapping of pets for the pet trade and disturbance of habitat, especially the massive removal of yatay palms which it could have gotten its primary food source. The Glaucous Macaw is listed as Critically Endangered.
Breeding
Glaucous Macaws form monogamous pair. Both parents are involved in raising their children. They breed during the dry season when food availability is at its greatest. The female will lay up to three eggs, which are incubated by the mother for around 28 days. For the first few weeks following hatching, the chicks are fed by their parents via regurgitation. The macaws' young begin to explore their surroundings and begin to learn to feed themselves. They also learn how to fly and forage.
The glaucous Macaw is extremely social bird. They are active during the day, but are restful at night. At night they often seek refuge in tree cavities or other suitable nesting places. 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 faces many threats including habitat loss and illegal trapping of the bird for the pet market, and deforestation. About 20 glaucous macaws are believed to exist in the wild. The IUCN has classified the bird as "Critically endangered, possibly extinct."
The glaucous macaw is also called the Lear's macaw, or the blue-throated hummingbird. It can be distinguished by its vibrant blue feathers. The parrot is 70 centimeters long and has an impressive beak that is capable of slicing open seeds and nuts. This gorgeous bird is native to South America, and it can be found in many habitats such as grasslands, forests, dry lowland and wetlands.
This majestic bird is a sign of South American biodiversity. It has a regal look with its slim body, vibrant blue feathers, and lightweight build. Its beak is curved and black, which aids it crack open the nuts and seeds that comprise a large portion of its diet. It is a stunning bird, and is frequently featured in bird shows. It is also a favourite in captivity, where it could be kept for a lifetime.
