Glaucous Macaw
The glaucous Macaw is one the rarest birds in the world. It is considered Critically Endangered and could be extinct in the wild.
The bird has been reported by aviculturists from various countries, but the latest sighting was reported in 1992. The alleged sighting was reported to be in southwest Paraguay near the city Corrientes. The bird was male.
Origin
The Glaucous harlequin macaw is an endangered parrot species native to South America. This majestic bird is distinguished by its distinctive blue feather pattern and a powerful beak that is capable of cracking open tough seeds and nuts. Glaucous macaws have been known to form long-term monogamous families and both parents are involved in the raising of the chicks. The chicks are fed regurgitated food in the first few weeks of their lives, and then solid foods as they grow. Parents are also responsible for teaching the young macaws to fly and hunt.
The glaucous Ziggy Our Scarlet Macaw is extinct, yet rumors of its existence persist around the world. The glaucous Macaw is believed to have been extinct in the 1800s due to cattle grazing on yatay (Butia) palm groves from which the birds gathered their food. The glaucous Macaw is believed to have returned, and is usually kept with 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 many palm trees. They are also known to be highly adaptable to a variety of forested environments. These beautiful birds can be territorial and will protect the feeding and nesting area from intruders.
There have been a number of reports on the glaucous macaw through the years, but many are considered to be not reliable. The most recent claim of a wild occurrence involves an avicultural acquaintance of Ridgely's who claimed to have seen four Glaucous macaws in Califomia. This claim is untrue until it is substantiated with evidence. The absence of any reliable evidence of this bird in the past century has caused many experts to conclude that it is likely extinct, however they have always been open to an extremely remote possibility of its existence (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it survives, it will be extremely uncommon to witness large numbers.
Habitat
The glaucous macaw is a striking bird that is renowned for its size and dazzling turquoise-blue coloration. The tail feathers and wings are long, enhancing its fluid and graceful movements. The bird is a symbol of loyalty and love. Its beak, which is predominantly black, has a distinct shape that allows it to crack nuts and seeds. They are a significant part of its diet.
The Glaucous Macaw is considered Critically Endangered by the IUCN which states that it has a small population and is at high chance of becoming extinct. This species was once widespread but is now found in northern Argentina south Paraguay and north-eastern Uruguay as well as Brazil from Parana state to south, where it resides in cliffs along major rivers.
Although there have been no credible sightings of the species since 1830 however, the Glaucous Macaw seemed not to be very rare in its relatively limited range; specimens were collected up to 1850 (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 re-examination of the historical records suggests that this species was a very generalist in its habitat preferences with a preference for savanna habitat intermingled with palm "islands" and areas of riparian forest along river systems. It was a specific eater of palm fruits, particularly those of the yatay or chatay palm (Butia yatay), but it could also consume ripe and unripe fruits as well as berries, nuts and vegetables. It is a nesting place on steep slopes or in cliffs, and also in tree cavities.
The bird was likely to be gregarious and social, just like other parrots. It was able to live up to 14.8 years in captivity and was said to be a reliable breeder, reproducing year after year. The life expectancy of this species in the wild was between 50 and 80 years. This species was a potent seed disperser and may have contributed to the success of the yatay palm within its natural habitats.
Feeding
The Glaucous Macaw (Anodorhynchus glaucus) is one of the most magnificent of all the species of parrots and has a an immense impact in its environment. This large South American parrot is known for its bright blue feathers, yellow eyes and the teardrop-shaped lappet on its lower beak.
In the past, little was known about diet 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 stay in Brazil and later in his work "As Birds of the Brazilian Forests". Both are about the Hyacinthine Macaw, Anodorhynchus Aureolarius. I have no reason to believe that they do not apply to this species.
It is likely that the Glaucous Macaw was a specialized for the consumption of palm nuts. It also consumed other seeds, fruits and vegetable matter in small quantities. This species' diet was likely affected by the clearing of forests for agriculture and cattle-ranching by early colonists, as well the felling of yatay (Butia) palms from which it derived a lot of its nutritional value.
In the wild in the wild, the Glaucous Macaw was found in subtropical forests containing mountains and savannahs that were surrounded by palm trees, where it nestled in tree cavities, on rocky banks or the palm fronds' top. On average two eggs were laid in a clutch. eggs was laid and then incubated by the female.
The young Glaucous Macaws are altricial, which means they depend on their parents to care for them until they are fully fledged and can fly. Both males and females are very dedicated to their offspring, and hunt for food and protect them from predators.
Unfortunately, the Glaucous Macaw has been eliminated from most of its former range. The disappearance of this magnificent bird is likely to be due to continued trapping for the pet industry as well as habitat disruption, especially the massive removal of palm yatays, which may have been its main food source. The Glaucous Macaw is listed as Critically Endangered.
Breeding
Glaucous macaws typically form long-term monogamous couples, with both parents playing part in raising the young. They breed during the dry season, when food is most abundant. Females lay two to three eggs that are incubated by the mother for around 28 days. When the chicks are born they are fed by their parents through regurgitation during the first few weeks of their life. Macaws are then able exploring and learning to feed themselves. They also learn how to fly and hunt for food.
Like all birds, glaucous macaws are social animals. They are active during the day, but sleep at night. They usually seek shelter in tree cavities or other suitable nesting sites for the night. Their calls can be heard in the forest throughout the day.
While it is hoped that the species will be able to recover from its decline in the wild, the bird faces many threats, including loss of habitat illegal trapping for the pet trade and deforestation. It is believed that there are less than 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 Lolita blue & gold macaw feathers. The parrot is 70 centimeters long and has powerful beaks that are capable of slicing open nuts and seeds. This beautiful bird is native to South America, and it is found in various habitats like forests, dry lowland grasslands and wetlands.
This magnificent bird is an emblem of South American biodiversity. It has a regal look with its slender body, vibrant blue feathers and its light build. Its black and curved beak helps it crack open nuts and seeds, which comprise a significant portion of its diet. It's a beautiful bird, and is often used in bird shows. It is also a popular bird in the wild, where it can remain for a long time.
