Glaucous Macaw

The glaucous Macaw is among the rarest birds in the world. It is in serious danger and may even be extinct.

Various Aviculturalists have reported sightings of this bird However, the most recent sighting was in 1992. The reported sighting was in southwest Paraguay close to the city of Corrientes. The bird was male.

Origin

The Glaucous macaw is an endangered parrot species native to South America. This magnificent bird is distinguished by the blue feather pattern and a sharp beak that can break open nuts and seeds. Glaucous macaws form long-term monogamous pairs and both parents assist in raising the chicks. They feed the chicks regurgitated food for the first couple of weeks after birth, and later they begin eating solid foods as they grow. 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 spread around the world. The glaucous Macaw is believed to be extinct by the 1800s due to the logging industry and cattle grazing in yatay (Butia) palm groves, where the birds gathered their food. The glaucous harlequin macaw is believed to have returned, and is usually kept with its larger mate, Lear's macaw.

In terms of habitat, the glaucous macaw can be found in the sub-tropical forests of South America. They are most often found in areas with abundant palm trees, and they are thought to be extremely adaptable to various types of forested habitats. These beautiful birds are territorial and will defend the nesting and feeding area from intruders.

There have been a lot of reports about the glaucous macaw through the years, but most are considered to be unreliable. The most recent report of a wild occurrence involves an friend of Ridgely's that claimed to have seen four Glaucous macaws in Califomia. This is a completely absurd claim until it is verified with hard evidence. Many experts have concluded that the bird is likely extinct because there are no records in the last century. However they have always been willing to accept a slim chance of its survival. If it survives, it is extremely unlikely to reach large numbers.

Habitat

The glaucous macaw is a striking bird, renowned for its huge size and stunning turquoise-blue coloration. The tail and wings are long, which enhances its graceful and agile movement. This bird is an emblem of love and loyalty. Its beak is mostly black and has a distinctive shape that allows it to break open nuts and seeds, which comprise a large portion 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 significant danger of disappearing. The species was once relatively widespread, but it is only found in northern Argentina as well as southern Paraguay, north-eastern Uruguay and Brazil from Parana state southwards, where it is nestled in cliffs on major rivers.

Although there haven't been any confirmed sightings of this species since 1830 however, the Glaucous Macaw seemed not to be a rare species in its relatively limited range; specimens were collected from 1830 to 1860 (in Corrientes). The last known living Glaucous Macaw was exhibited at the Buenos Aires Zoo in 1936 and is believed to have come from Brazil.

Reassessment suggests that this species is a generalist and prefers areas of savanna that are interspersed with palm "islands" and riparian forest bands along river systems. It was a particular eater of palm fruits, especially those of the chatay or yatay palm (Butia yatay) but it was likely to also consume unripe and ripe fruits as well as berries, nuts and vegetable matter. It nested on steep slopes and in 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 and was believed to be a dependable breeder that reproduced year after year. In the wild, its life expectancy was likely to be between 50 and 80 years. This species was a formidable seed disperser and could 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 parrot species and has a an immense impact in its environment. This massive South American bird is known for its vivid blue feathers and eyes that are yellow, as well as the distinctive teardrop-shaped lappet which adorns the lower portion of its beak.

In the past, little was known about eating habits of the Glaucous Macaw. The first references to the subject I have discovered are in two books by H.W. Bates' "The Naturalist on the amazons", first published in 1863, describes his 11-year stay in Brazil. Later, in his book "As Birds of the Brazilian Forests" He wrote about the similar experience. Both of these references to the Hyacinthine Macaw (Anodorhynchus aureolarius) however I see no reason to believe that they are not applicable to this species.

It is probable that the Glaucous Macaw was a particular in the consumption of palm nuts, and also consumed other seeds, fruits, and vegetable matter in small amounts. The diet of this species is likely to have been influenced by the clearance of forests by the early colonists for agriculture and cattle ranching and the felling of the yatay palm (Butia yatay) from which it could have gotten its majority of its food.

In the wild the Glaucous Macaw was found in subtropical forests with cliffs and savannahs with palm trees where it nested in tree cavities and on rocky banks or the top of palm fronds. On average two clutches of eggs was laid and then incubated by the female.

The young Glaucous Macaws are altricial, which means they depend on their parents to take care of them until they're fully fledged and can fly. Both males and females are dedicated to their offspring, and hunt for food and defend them from predators.

Unfortunately, the Glaucous Macaw has been extirpated from most 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 may have obtained its main food supply. The Glaucous Macaw is listed as Critically Endangered.

Breeding

Glaucous macaws typically form long-term monogamous pairs and both parents play part in raising the young. They breed in the dry season when food availability is at its highest. The female lays two to three eggs that are incubated by the mother for about 28 days. After hatching they are fed by their parents via regurgitation for the first couple of weeks of their lives. The young macaws then begin to explore their surroundings and learn how to eat themselves. They also learn to fly and forage.

Like all birds, glaucous macaws are extremely social creatures. They are active during the day, but are restful at night. They usually seek shelter in tree cavities or other suitable nesting places for the night. They are very vocal and their calls can be heard throughout the forest during the day.

The species is expected to rebound from the decline, however it faces many threats including habitat loss, illegal trapping of the bird for the pet market, and deforestation. It is believed that there are just 20 glaucous macaws that are in the wild. The IUCN has classified the bird as "Critically endangered, possibly extinct."

The glaucous macaw cage is known as the Lear's Ziggy hyacinth macaw parrots for sale, or the Melody blue spix macaw-throated hummingbird, and is distinguished by its vibrant blue feathers. The parrot is 70 centimeters in length and has a powerful beaks that are capable of slicing open nuts and seeds. This gorgeous bird is native to South America, and it can be found in many habitats such as forests, dry lowland grasslands, and wetlands.

This magnificent bird is an emblem of South American biodiversity. Its elegant appearance is reflected with its slim body, vibrant blue feathers and its light build. The black and curly beak allows it to break open seeds and nuts, which are a large part of its diet. It is a great-looking bird, and it's often seen in bird shows. It is also popular in captivity, where it can live a lifetime.
