Glaucous Macaw

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

This bird has been reported by aviculturists across the globe however the most recent sighting was reported in 1992. The reported sighting was in southwestern Paraguay close to the city of Corrientes. The bird was a male.

Origin

The Glaucous macaw is a threatened parrot species that is native to South America. This magnificent bird has a unique blue feather pattern and powerful beak capable of cracking open tough seeds and nuts. Glaucous macaws form long-term monogamous families and both parents help raise the chicks. They feed their chicks regurgitated food for the first few weeks after birth, and later they begin eating solid foods as they develop. Parents are also responsible for teaching young macaws to fly and hunt.

The glaucous Macaw is extinct, yet rumors of its existence persist across the globe. The glaucous Macaw is believed to have gone extinct in the 1800s because of cattle grazing on yatay (Butia) palm groves from which the birds would gather their food. The glaucous Macaw is believed to have made a comeback, and is usually kept with its larger relative, Lear’s macaw cage.

In terms of habitat, the glaucous macaw can be found in the sub-tropical forests of South America. They are typically located in areas with a lot of palm trees, and are known to be highly adaptable to a variety of forested habitats. These beautiful birds are territorial and will defend the nesting and feeding areas from intruders.

There have been a variety of reports about the glaucous macaw throughout the years, but many are considered to be unreliable. The most recent claim of a wild incident is an friend of Ridgely's that claimed to have witnessed four Glaucous macaws in Califomia. This claim is completely unacceptable until it is confirmed with solid evidence. Many experts have concluded that this bird is likely extinct because there are no records in the last century. However they have been willing to accept a slim chance of its survival. If it survives, it is extremely unlikely to make it to huge numbers.

Habitat

The glaucous macaw is a striking bird, renowned for its large size and striking turquoise-blue coloration. Its long tail and wings highlight its graceful and agile moves. The bird is also an emblem of love and loyalty. Its beak is predominantly black, and it has a distinctive shape that allows it to open seeds and nuts which make up a large part of its diet.

The Glaucous Macaw is considered Critically Endangered by the IUCN and the IUCN states that it has a small population and is at a high risk of extinction. This species was once widespread but is now found in northern Argentina south Paraguay and north-eastern Uruguay and Brazil, from Parana state to south, where it is nestled in cliffs along major rivers.

While there have been no reliable sightings of this species since 1830 however, the Glaucous Macaw seemed not to be a rare species in its comparatively small range; specimens were collected until 1860 (in Corrientes). The last known living Glaucous Pixie mini macaw was displayed at the Buenos Aires Zoo in 1936 and is believed to have come from Brazil.

The reassessment suggests that the species is a generalist and prefers areas of savanna that are interspersed with palm "islands" and bands of riparian forests along rivers. It was a particular for the consumption of palm fruits, 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 nestled on 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 likely to be sociable. It could live up to 14.8 years in captivity. It was said to be a dependable breeder, reproducing year after year. In the wild, its lifespan was probably 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 native habitats.

Feeding

The Glaucous Macaw (Anodorhynchus glaucus) is among the most beautiful of the species of parrots and its presence has an immense impact in its environment. This large South American parrot is known for its vibrant blue feathers, yellow eyes and the teardrop-shaped lappet on its lower beak.

In the past, little was known about the feeding habits of the Glaucous Macaw. The first detailed references I have discovered are in two books by H.W. Bates, "The Naturalist on the Amazons" first published in 1863 about his 11 year stay in Brazil and later in his book "As Birds of the Brazilian Forests". Both of these refer to the Hyacinthine Macaw (Anodorhynchus aureolarius) however I see no reason to think that they are not applicable to this species.

It is probable that the Glaucous harlequin macaw was a specialist for the consumption of palm nuts. It also took other seeds, fruits and vegetable matter in small amounts. The diet of this species is likely to be influenced by the clearance of forests by the early colonists for agriculture and cattle ranching, as well as the removal of the yatay palm (Butia yatay) from which it may have received much of its nutrition.

In the wild the Glaucous Macaw was often found in subtropical forests with mountains and savannahs that were surrounded by palm trees, where it nestled in tree cavities and on rocky banks or in the top of palm fronds. The female incubates and Glaucous Macaw then lays two eggs per.

The young Glaucous Macaws are altricial, meaning they rely on their parents to take care of them until they're fully grown and fly. Both males and females are very dedicated to their offspring, and hunt for food and defend them against predators.

Unfortunately unfortunately, the Glaucous Macaw has been eliminated from its entire former range. The disappearance of the majestic bird is likely to be due to continued trapping for the pet industry, as well as disturbance to habitat, particularly the mass clearing of palm yatays which may have been its main food source. The Glaucous Macaw is listed as Critically Endangered.

Breeding

Glaucous macaws are typically monogamous pairs and both parents play an active role in the raising of the young. They breed in the dry season when food availability is at its highest. The female lays a clutch of two to three eggs, which are incubated for about 28 days. For the first few weeks after hatching the chicks are fed by the parents through regurgitation. The macaws' young begin to explore their surroundings and learn how to eat themselves. They are also taught how to fly and forage.

Like all birds, glaucous macaws are extremely social creatures. They are active during daylight hours and rest at night. During the night they often seek refuge inside tree cavities or other nesting spots that are suitable. They are very vocal and their calls can be heard throughout the forest during the day.

The species is expected to rebound from its decline, however it is in danger of being wiped out by habitat loss illegal trapping of the bird for the pet market, and deforestation. It is estimated that there are just 20 glaucous macaws in the wild. The IUCN classifies the bird as "Critically Endangered - possibly Extinct."

The glaucous Macaw, also known 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 can break open hard nuts and seeds. The beautiful bird is native to South America and can be found in a variety of habitats such as grasslands, forests, and lowland wetlands.

This magnificent bird is a symbol of South American biodiversity. Its elegant appearance with its slim body, light weight and bright blue feathers. Its black and curved beak allows it to break open seeds and nuts which are a large part of its diet. It is a beautiful bird and is often used in birds shows. It is also popular in captivity, where it can live for a lifetime.
