Glaucous Macaw
The glaucous Macaw is among the rarest birds in the world. It is considered Critically Endangered, and may be extinct in the wild.
This bird has been reported by aviculturists across the globe However, the most recent sighting was in 1992. This alleged sighting occurred in southwestern Paraguay close to the city of Corrientes. The bird was male.
Origin
The Glaucous Macaw is a parrot native to South America. It is endangered. This magnificent bird features a unique blue feather pattern and powerful beak capable of breaking open tough nuts and seeds. Glaucous Macaws live in monogamous pair and both parents tend 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 grow. The parents also play a vital role in teaching the young macaws how to fly and forage.
The glaucous macaw is believed to be extinct in the wild, yet reports of this beautiful bird's existence persist throughout the world. The Glaucous Macaw is believed be extinct by the 1800s due to cattle grazing on yatay (Butia) palm groves where the birds would gather their food. It is currently believed that the glaucous macaw returned to captivity, where it is often 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 typically located in areas with a lot of palm trees, and are thought to be extremely adaptable to a variety of forested habitats. These beautiful birds are territorial and will protect the nesting and feeding area from intruders.
There have been a number of reports involving the glaucous macaw over the years, but many are considered to be unreliable. The most recent claim of a wild incident is a friend of Ridgely's that claimed to have observed four Glaucous macaws in Califomia. This is a completely absurd claim until it is verified with hard evidence. The absence of any reliable records of this bird in the past century has led many experts to conclude that it is likely extinct, yet they have always been willing to accept the possibility of survival (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it does survive it will be very rare to see large numbers.
Habitat
The macaw glaucous is an impressive bird, renowned for its huge size and striking turquoise-blue coloring. The long tail and wings highlight its graceful and agile moves. The bird is also an emblem of loyalty and love. Its beak is predominantly black, and it has a unique shape that allows it to break open seeds and nuts, which comprise a large part of its diet.
IUCN has classified the Glaucous Macaw as Critically Endangered. It says that there is a very small population of this bird and it is at high-risk of extinction. This species was once widespread but is now found in northern Argentina and south Paraguay and north-eastern Uruguay as well as Brazil, from Parana state to south, where it resides in cliffs that run alongside major rivers.
The Glaucous Macaw was not rare in its small range, even though there was no proof of sightings after 1830. The specimens were collected until the year 1860 (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 very generalist in its preferences for habitat and preferred areas of savanna that were interspersed with palm "islands" and forests of riparian along river systems. It was a specific feeder of palm fruits, particularly those of the chatay palm (Butia yatay) however, it was also likely to feed on ripe and unripe fruits as well as berries, nuts and vegetables. It nestled on slopes and in cliffs sometimes in tree cavities and laid an average clutch of two eggs.
This bird was likely gregarious and social, just like other parrots. It was reported that it could live for up to 14.4 years in captivity and was a reliable breeder that reproduced year after. Its life expectancy in the wild was 50-80 years. This species was a potent disperser of seeds and may be a factor in the success of the palm yatay in its natural habitat.
Feeding
The Glaucous Macaw (Anodorhynchus glaucus) is one of the most magnificent of all the parrot species and its presence has an enormous impact on its surroundings. This large South American parrot is known for its vibrant blue feathers, yellow eyes and the teardrop-shaped lappet on the lower part its beak.
Up until recently, very little was known about food habits and diet of the Glaucous macaw. The first detailed references I have found are two works by H.W. Bates' "The Naturalist on the amazons", first published in 1863, and describes his 11-year journey in Brazil. Later in his book "As Birds of the Brazilian Forests" Bates wrote about the same experience. Both of them are about the Hyacinthine Macaw, Anodorhynchus Aureolarius. There is no reason to believe that they don't apply to this species.
It is probable that the Glaucous Macaw was a specialist for the consumption of palm nuts. It also took 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, and the removal of yatay (Butia) palms from which it derived a lot of its nutritional value.
In the wild, it was common to see the Glaucous macaw in savannahs and subtropical forests where palm trees were found. It hid in tree cavities, or on rocky banks and palm fronds. On average two clutches of eggs was laid and incubated by the female.
The young Glaucous Macaws are altricial, meaning they rely on their website parents to care for them until they're fully grown and fly. Both the males and females are very dedicated to their offspring, and will hunt for food and defend them from predators.
Unfortunately unfortunately, the Glaucous macaw is no longer found in its former habitat. The disappearance of this magnificent bird is probably due to the continued trapping of pets for the pet trade, as well as disturbance to habitat, specifically the mass removal of yatay palms where it could have gotten its main food supply. The Glaucous macaw is listed under Critically Endangered.
Breeding
Glaucous macaws usually form long-term monogamous pairs with both parents taking a role in raising the young. They breed during the dry season, when food availability is at its highest. Females lay a clutch of two to three eggs, which are incubated for about 28 days. After hatching they are fed by their parents through regurgitation during the first few weeks of their lives. The young macaws begin to explore and learn to feed themselves. They also learn how to fly and forage.
Like all species of birds, glaucous macaws are highly social creatures. They are active during the day, but are restful at night. They usually seek shelter in cavities in trees or other suitable nesting sites to sleep. Their calls can be heard in the forest throughout the day.
The species is expected to recover from the decline, but it is facing numerous threats, including habitat loss, illegal trapping of the bird to sell on the pet market and deforestation. Only about 20 glaucous Macaws are believed to exist in the wild. The IUCN classifies 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 vivid blue feathers. It is a large parrot, measuring 70 centimeters in length, and has a strong beak that is able to break open seeds and nuts that are tough to break. This beautiful bird is native South America and can be found in various habitats such as grasslands, forests, and lowland wetlands.
This magnificent bird is a sign of South American biodiversity. Its elegant appearance with its slim body, light build and bright blue feathers. Its black and curved beak makes it easier to crack open seeds and nuts, which make up a significant part of its diet. It's a beautiful bird, and it's often seen in shows featuring birds. It is also popular in captivity where it can live a lifetime.
