Glaucous Macaw

The glaucous Macaw is among the rarest birds in the world. It is considered Critically Endangered and could become extinct in the wild.

The bird has been reported by aviculturists in various countries, but the latest sighting was recorded 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 threatened parrot species native to South America. This magnificent bird has a distinctive blue feather pattern as well as a strong beak that is capable of breaking open hard seeds and nuts. Glaucous Macaws form monogamous long-term couples and both parents tend the chicks. They feed their chicks regurgitated food for the first few weeks after birth, and later they begin to eat solid foods as they grow. The parents also play a vital role in teaching young macaws to fly and hunt.

The glaucous Macaw is extinct, but rumors about its existence continue to spread across the globe. The glaucous Macaw is believed to be extinct by the 1800s because of logging and cattle grazing on yatay (Butia) palm groves where the birds gathered their food. It is believed that the glaucous Macaw has returned to captivity, where it is often kept with its larger cousin Lear's macaw.

In terms of habitat the glaucous macaw can be found in the sub-tropical forests of South America. They are usually found in areas with many palm trees. They are also extremely adaptable to different types of forested environments. These beautiful birds are known to be extremely territorial and will protect their feeding and nesting areas from invaders.

In the past, there have been numerous reports of the glaucous macaw however they are generally regarded as unreliable. The most recent claim of a wild occurrence involves an friend of Ridgely's who claimed to have seen four Glaucous macaws in Califomia. This is a ridiculous claim until it is supported with hard evidence. Many experts have concluded that the bird is likely extinct as there are no records in the last century. However they have been willing to accept a small chance of its survival. If it survives it will be extremely rare to see large numbers.

Habitat

The glaucous macaw is a striking bird that is known for its size and striking turquoise-blue coloration. Its long tail and wings highlight its graceful and agile moves. This bird is a symbol of love and loyalty. Its beak is mostly black, and it has a unique shape that allows it to open seeds and nuts which comprise a large part of its diet.

IUCN has classified the Glaucous Macaw as Critically Endangered. It states that there is a very small population of the bird and it is at high-risk of extinction. The species was previously relatively widespread, but it is only found in northern Argentina, southern Paraguay, north-eastern Uruguay and Brazil from Parana state southwards where it is nestled in cliffs on major rivers.

While there have been no credible sightings of the species since 1830 The Glaucous Macaw seemed not to be a rare species in its comparatively small range; specimens were taken from 1830 to 1850 (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 rather generalist in its habitat preferences with a preference for savanna habitat intermingled with palm "islands" and forests of riparian along rivers. It was a specialist in the consuming of palm fruit especially those of the yatay (or chatay) palm (Butia). However, it also ate ripe and unripe fruits as well as berries, nuts and other vegetable matter. It nested on steep slopes and in cliffs, occasionally in tree cavities and laid an average clutch of two eggs.

Like all parrots, this bird was social and probably gregarious. It was reported that it could live to 14.4 years in captivity and was a reliable breeder who reproduced year after. In the wild, its life expectancy was likely to be between 50 and 80 years. This species was a powerful seed disperser and could have contributed to the success of the yatay palm within its natural habitats.

Feeding

The Glaucous Macaw is one of the most beautiful parrots. The presence of this parrot has an enormous impact on its environment. This huge South American parrot is known for its bright blue feathers, bright yellow eyes and the teardrop-shaped lappet on the lower part its beak.

As of the time of writing, little was known about the food habits and diet of the Glaucous macaw. The first detailed references I have discovered are in two books by H.W. Bates' "The Naturalist on Amazons" first published in 1863, which describes his 11-year sojourn in Brazil. Later in his book "As Birds of the Brazilian Forests" He wrote about the similar experience. Both of these are about the Hyacinthine Macaw (Anodorhynchus aureolarius) however I see no reason to think that they're not applicable to this species.

It is probable more info that the Glaucous Macaw was a specialized feeder of palm nuts and also took other seeds, fruits, and vegetable matter in smaller amounts. The diet of this species is likely to have been affected by the clearing of forests by 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 often found in subtropical forests that had mountains and savannahs that were surrounded by palm trees, where it nestled in tree cavities, on rocky banks, or in the top of palm fronds. On average, a clutch of two eggs was laid and incubated by the female.

The young Glaucous Macaws rely on their parents for care until they fly and become fully fledged. Both the male and female are extremely committed to their young and will constantly hunt for food and defend them from predators.

Unfortunately the Glaucous macaw isn't found in its former habitat. The disappearance of the majestic bird is likely to be due to the continued trapping of birds for the pet industry, as well as disturbance of habitat, specifically the mass removal of palm yatays, which may have been its primary food source. The Glaucous Macaw is listed as Critically Endangered.

Breeding

Glaucous macaws usually form long-term monogamous couples, with both parents playing an active role in the raising of the young. They breed during the dry season when the availability of food is at its highest. The female lays an egg clutch that ranges from two to three eggs, which are incubated for around 28 days. Once the chicks hatch they are fed by their parents through regurgitation during the first few weeks of their lives. The macaws' young begin to explore their surroundings and begin to learn to eat themselves. They also learn to fly and forage.

The glaucous Macaw is a very social bird. They are active during daylight hours and take a break at night. They will often seek shelter in cavities in trees or other nesting spots for the night. Their calls can be heard throughout the forest throughout the day.

While it is believed that the species will recover from its decline in the wild, the bird is facing numerous threats, including the loss of habitat illegal trapping for the pet trade and deforestation. It is estimated that there are less than 20 glaucous macaws that are in the wild. The IUCN classifies the bird as "Critically Endangered, possibly extinct."

The glaucous Macaw is sometimes referred to as Lear's Macaw or Blue-throated Hummingbird is distinguished by its vibrantly blue feathers. The parrot is 70 centimeters long and features a an impressive beak that is capable of slicing open nuts and seeds. This beautiful bird is native South America and can be found in a variety of habitats such as grasslands, lowland forests and wetlands.

This magnificent bird is a symbol of South American biodiversity. It has a regal appearance with its slim build, lightweight body and vivid blue feathers. The black and curly beak makes it easier to crack open nuts and seeds, which comprise a significant portion of its diet. It is a beautiful bird that is often seen in bird shows. It is also a favorite in captivity, where it could live for a lifetime.
