Glaucous Macaw
The glaucous macaw is considered to be one of the world's rarest birds. It is Critically Endangered, and may be extinct in the wild.
A variety of Aviculturalists have reported sightings of this bird however the most recent sighting was in 1992. The reported sighting was in the southwestern region of Paraguay, near the city of Corrientes. The bird was a male.
Origin
The Glaucous Macaw is a species of parrot native to South America. It is threatened. This magnificent 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 pairs and both parents are involved in the raising of the chicks. They feed the chicks a diet of regurgitated food for the first couple of weeks after birth, and later they begin eating solid foods as they develop. Parents are also responsible for teaching the young macaws to fly and hunt.
The glaucous Macaw is thought to be extinct in the wild, however stories of this gorgeous bird's existence are still spreading throughout the world. It is believed that the glaucous macaw extinct in the 1800s because of logging and cattle grazing of yatay palm (Butia yatay) groves, where these birds mostly ate their food. The glaucous Macaw is believed to have returned, and is often kept with its larger mate, Lear's macaw.
In terms of habitat The glaucous macaw is able to be found in sub-tropical forests of South America. They are usually located in areas with a lot of palm trees, and they are believed to be extremely adaptable to a variety of forested habitats. These beautiful birds are also recognized as being very territorial and will defend their feeding and nesting areas from invaders.
There have been a number of reports on the glaucous macaw over the years, but many are considered to be unreliable. The most recent report of a wild incident is a avicultural acquaintance of Ridgely's who claimed to have witnessed four Glaucous macaws in Califomia. This claim is untrue until it is substantiated by solid evidence. The lack of any acceptable evidence of this bird in the last century has caused many experts to think that it's likely extinct, yet 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 glaucous Macaw is an impressive bird, renowned for its size and turquoise-blue coloration. Its wings and tail feathers are long, which enhances its fluid and graceful moves. It is also a symbol of loyalty and love. Its beak is predominantly black, and it has a distinctive shape that allows it to open nuts and seeds, which constitute a significant portion of its diet.
IUCN has classified the Glaucous Macaw as Critically Endangered. It says that there is a small population of this bird and it is in high-risk of extinction. This species was once widespread however, it is now found in northern Argentina and 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 limited area, despite the fact that there were no reliable sightings since 1830. There were specimens taken up until the year the year 1860 (in Corrientes). The last known living Glaucous Macaw was exhibited at the Buenos Aires Zoo in 1936 and is believed to be from Brazil.
Re-evaluation of the historical documents suggests that this species was more generalist in its habitat preferences with a preference for savanna habitat intermingled with palm "islands" and forests of riparian along rivers. It was a specific eater of palm fruits, specifically those of the chatay palm (Butia yatay) but it was likely to also feed on ripe and unripe fruits such as berries, nuts, and vegetables. It nested on steep slopes and cliffs, sometimes in tree cavities and laid an average clutch of two eggs.
As with other parrots this bird was social, and was probably gregarious. It could live for up to 14.8 years in captivity. It was said to be a reliable breeder, reproducing year after year. Its life expectancy in the wild was 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 (Anodorhynchus glaucus) is one of the most beautiful of the parrot species and its presence has a powerful impact in its surroundings. This large South American parrot is known for its vibrant blue feathers, yellow eyes, and the teardrop-shaped lipped on the lower part its beak.
In the past, little was known about feeding habits of the Glaucous Macaw. The earliest references to this subject that I have come across 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 them are about the Hyacinthine Macaw Anodorhynchus Aureolarius. I have no reason to believe that they do not apply to this species.
The Glaucous macaw is likely to be a specialist eater, consuming only palm nuts however, there were also tiny amounts of other seeds, fruits and vegetable matter. The diet of this species was likely influenced by the clearing of forests for agriculture and cattle-ranching by early colonists, and the yatay (Butia) palms from which it received much of its nutrition.
In the wild, it was common 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 Ziggy Our Scarlet Macaw and palm fronds. On average, a clutch of two eggs was laid and then incubated by the female.
The young Glaucous Macaws rely on their parents for their care until they fly and fully fledged. Both males and females are very committed to their offspring and hunt for food and defend them from predators.
Unfortunately unfortunately, the Glaucous Macaw has been eliminated from the majority of its former range. The disappearance of the majestic bird is likely to be due to trapping that continues for the pet industry and disturbance to habitat, particularly the wholesale removal of palm yatays, which may have been its primary food source. The Glaucous macaw is listed as Critically Endangered.
Breeding
Glaucous macaws typically form long-term monogamous couples with both parents taking a role in raising the young. They breed in the dry season when food availability is at its greatest. The female lays an egg clutch that ranges from two to three eggs, which are incubated for a period of around 28 days. For the first few weeks after hatching, the chicks are fed daily by their parents via regurgitation. Macaws are then able to explore and learn to feed themselves. They also learn to fly and hunt for food.
Like all birds, glaucous Macaws are social animals. They are active during daylight hours, and take a break at night. They often seek refuge in cavities in trees or other nesting spots to sleep. 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 and illegal trapping for pet trade, and deforestation. There are only about 20 glaucous Macaws that are estimated to be living in the wild. The IUCN has classified the bird as "Critically endangered--possibly extinct."
The glaucous macaw, sometimes referred to as Lear's Macaw or Blue-throated Hummingbird, is distinguished by its vibrantly blue feathers. It is a large parrot, with a length of 70 centimeters and has a sturdy beak that can crack open seeds and nuts that are tough to break. This beautiful bird is native South America and can be found in diverse habitats, including grasslands, lowland forests and wetlands.
This majestic bird is a symbol of South American biodiversity. Its appearance is elegant with its slim build, lightweight body and vivid blue feathers. Its black and curved beak allows it to break open nuts and seeds, which are a large part of its diet. It is a great-looking bird, and it is often used in shows featuring birds. It is also popular in captivity where it can live for a lifetime.
