Glaucous Macaw
The glaucous Macaw can be described as one of the rarest birds in the world. It is in danger of disappearing and could even be extinct.
Many Aviculturalists have reported sightings of this bird, but the most recent was in 1992. The alleged sighting was reported to have occurred in southwestern 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 magnificent bird has a unique blue feather pattern and powerful beak that is capable of breaking open hard nuts and seeds. Glaucous Macaws live in monogamous pair and both parents care for the chicks. The chicks are fed regurgitated food in the first few weeks of life, and then solid foods as the chicks develop. Parents are also responsible for teaching the young macaws to fly and hunt.
The glaucous Macaw is extinct, but rumors about its existence persist across the globe. It is believed that the glaucous macaw was extirpated in the 1800s due to the logging industry and cattle grazing in yatay palm (Butia yatay) areas, where the birds mostly ate their food. It is currently believed that the glaucous macaw has made a comeback in captivity in the wild, where it is raised alongside its larger relative Lear's macaw.
In terms of habitat The glaucous macaw is able to be found in sub-tropical forests of South America. They are most often found in areas that have plenty of palm trees, and they are believed to be extremely adaptable to a variety of forested habitats. These beautiful birds can be territorial and defend the nesting and feeding areas from intruders.
There have been a number of reports involving the glaucous macaw through the years, but many are considered to be not reliable. The most recent report of a wild event is an friend of Ridgely's who claimed to have seen 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 past century has led many experts to conclude that it is likely extinct, yet they have always accepted a remote possibility of its existence (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it does survive it is highly unlikely to make it to huge numbers.
Habitat
The glaucous Macaw is an impressive bird, well-known for its large size and turquoise-blue coloring. Its long tail and wings highlight its graceful and agile movements. This bird is also an emblem of loyalty and love. Its beak, which is predominantly black, has a distinctive shape and allows it to break seeds and nuts. They form a large part of its diet.
The Glaucous Macaw is considered Critically Endangered by the IUCN and the IUCN states that it is a small population and is at a high chance of becoming extinct. The species was once relatively widespread, but it is found in northern Argentina, southern Paraguay, north-eastern Uruguay and Brazil from Parana state southwards, where it is nestled in cliffs on major rivers.
The Glaucous Macaw was not rare in its small area, even though there was no proof of sightings since 1830. Specimens were collected up until the year 1860 (in Corrientes). The last known living Glaucous Macaw was displayed at the Buenos Aires Zoo in 1936 and is believed to have come from Brazil.
A reassessment of the historical records suggests that this species was a more generalist in its preferences for habitat and preferred areas of savanna that were interspersed with palm "islands" and bands of riparian forest along river systems. It was a specific eater of palm fruits, specifically those of the chatay or yatay palm (Butia yatay), but it was also likely to consume unripe and ripe fruits, nuts, berries and vegetable matter. It nestled on slopes and in cliffs sometimes in tree cavities and laid an average clutch of two eggs.
Like other parrots, this bird was social, and was likely to be sociable. It was able to live up to 14.8 years in captivity and was believed to be a reliable breeder that reproduced year after year. The life expectancy of this species in the wild was about 50 to 80 years. This species was a powerful seed disperser and could have contributed to the success of the yatay palm in its natural habitats.
Feeding
The Glaucous Macaw (Anodorhynchus glaucus) is among the most magnificent of all the species of parrots and has a an immense impact in its surroundings. This massive South American bird is known for its vivid blue feathers and yellow eyes, as well as the distinctive teardrop-shaped lappet that brackets the lower portion of its beak.
Until recently very little was known about the eating habits 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 sojourn in Brazil and later in his book "As Birds of the Brazilian Forests". Both of these refer to the Hyacinthine Macaw (Anodorhynchus aureolarius) however I see no reason to think that they're not applicable to this species.
It is probable that the Glaucous Macaw was a specialized in the consumption of palm nuts, and also ate other seeds, fruits, and vegetable matter in small amounts. This macaw purchase species' diet was likely influenced by the clearing of forests for agriculture and cattle-ranching by early colonists, as well the 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 in which palm trees were present. It was found in tree cavities, or on rocky banks or palm fronds. The female incubates and then lays two eggs per.
The young Glaucous Macaws are altricial, meaning they depend on their parents to look after them until they are 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 has been extirpated from the majority of its previous range. The disappearance of the magnificent bird is likely due to the continued trapping of birds for the pet industry, as well as habitat disruption, especially the massive clearing of palm yatays which may have been its main food source. The Glaucous Macaw is listed as Critically Endangered.
Breeding
Glaucous Macaws form monogamous long-term couples. Both parents are involved in raising their young. They breed in the dry season when food availability is at its highest. Females lay two to three eggs that are incubated by the mother for approximately 28 days. For the first few weeks after hatching, the chicks are fed by the parents through regurgitation. The macaws' young begin to explore their surroundings and learn how to feed themselves. They are also taught to fly and forage.
Like all birds, glaucous macaws are extremely social creatures. They are active during the day but spend their nights resting. They will often seek shelter in cavities in trees or other suitable nesting places to sleep. Their calls can be heard in the forest throughout the day.
While it is hoped that the species will recover from its decline in the wild, the bird faces numerous threats, such as the loss of habitat and illegal trapping for pet trade and deforestation. It is estimated that there are just 20 glaucous macaws living in the wild. The IUCN classifies the bird as "Critically Endangered, possibly extinct."
The glaucous Macaw, sometimes referred to as Lear's Macaw, or the blue-throated Hummingbird is distinguished by its bright blue feathers. The parrot is 70 centimeters in length and has a a powerful beak capable of breaking open nuts and seeds. This gorgeous bird is native to South America and can be found in diverse habitats that include forests, lowland grasslands and wetlands.
This magnificent bird is a sign of South American biodiversity. Its appearance is elegant, with its slender body, light weight, and vibrant blue feathers. Its beak is curved and black, which aids it open the seeds and nuts that make up a major portion of its diet. It's a stunning bird, and it is often seen in bird shows. It is also popular in captivity where it can live for a long time.
