Glaucous Macaw

The glaucous macaw is one of the rarest birds on earth. It is in danger of disappearing and could be extinct.

Many aviculturalists have reported sightings of this bird However, the most recent sighting was in 1992. The alleged sighting was reported to have occurred in the southwestern region of Paraguay close to the city of Corrientes. The bird was a male.

Origin

The Glaucous Macaw is a parrot native to South America. It is threatened. This magnificent bird features a distinctive blue feather pattern and a powerful beak capable of cracking open tough seeds and nuts. Glaucous macaws have been known to form long-term monogamous pairs and both parents help raise the chicks. The chicks are fed regular food for the first couple of weeks of their lives, and then solid foods as the chicks develop. Parents are also responsible for teaching young macaws to fly and hunt.

The glaucous Macaw is extinct, but rumors about its existence persist around the world. It is believed that the glaucous Macaw was extinct in the 1800s due to the logging industry and cattle grazing in yatay palm (Butia yatay) groves, where these birds primarily gathered their meals. It is currently believed that the glaucous macaw has made a comeback in captivity in the wild, where it is kept with its larger cousin, Lear's macaw.

The glaucous Macaw is found in sub-tropical rainforests of South America. They are usually found in areas with abundant palm trees, and are believed to be extremely adaptable to different types of forested habitats. These beautiful birds can be territorial and will protect the feeding and nesting area from intruders.

In the past, there have been numerous reports of the glaucous macaw, but they are generally not considered reliable. The most recent claim of a wild event is an avicultural acquaintance of Ridgely's who claimed to have witnessed four Glaucous macaws in Califomia. This is completely untrue until it is confirmed with hard evidence. The absence of any reliable evidence of this bird in the last century has led many experts to believe that it is extinct, but they have always been open to an extremely remote possibility of its survival (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it survives, it is extremely unlikely to be seen in large numbers.

Habitat

The macaw to buy with the glaucous is a striking bird that is renowned for its size and stunning turquoise-blue coloring. The long tail and wings accentuate its graceful and agile moves. This bird is also a symbol of affection and loyalty. Its beak, which is primarily black, has a distinct shape and allows it to break seeds and nuts. These are a large portion of its diet.

The Glaucous Macaw is considered Critically Endangered by the IUCN and the IUCN states that it has an extremely small population and is at a high chance of becoming extinct. The species was once quite widespread, but today it is found in northern Argentina, southern Paraguay and north-eastern Uruguay and Brazil from Parana state southwards. It is nestled in cliffs on major rivers.

While there have been no reliable sightings of this species since 1830 The Glaucous Macaw seemed not to be a rare species in its relatively limited range; specimens were collected until 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.

Re-evaluation of the historical documents suggests that this species was more generalist in its preferences for habitat and preferred areas of savanna that were interspersed with palm "islands" and areas of riparian forest along rivers. It was a specialist for the consumption of palm fruits particularly those of the yatay (or chatay) palm (Butia). However, it also ate ripe or unripe fruits, nuts, berries, and vegetable matter. It nestled on slopes and cliffs, sometimes in tree cavities and laid an average clutch of two eggs.

The bird was likely to be gregarious and social, like other parrots. It was reported that it could live to 14.4 years in captivity and was a reliable breeder that reproduced year after year. The lifespan of the species in the wild was perhaps between 50 and 80 years. The species was a strong 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 among the most magnificent of all the species of parrots, and its presence commands an immense impact in its surroundings. This massive South American parrot is known for its vibrant blue feathers, yellow eyes and the teardrop-shaped lappet on its lower beak.

Until recently very little was known about eating habits of the Glaucous Macaw. The earliest detailed references I have found are in two publications by H.W. Bates, "The Naturalist on the Amazons" first published in 1863, detailing his 11 year sojourn in Brazil and later in his book "As Birds of the Brazilian Forests". Both are about the Hyacinthine Macaw, Anodorhynchus Aureolarius. There is no reason to believe that they do not apply to this species.

The Glaucous macaw is likely have been a specialist feeder, taking only palm nuts as well as tiny amounts of other seeds, fruits and vegetable matter. The diet of this species is likely to be affected by the clearing of forests by early colonists for agriculture and cattle ranching, as well as the removal of the yatay palm (Butia yatay) from which it could have gotten a lot of its food.

In the wild it was commonplace 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 eggs were laid in a clutch. eggs was laid and then incubated by the female.

The young Glaucous Macaws rely on their parents for care until they are able to fly and fully full fledged. Both males and females are extremely committed to their offspring and tirelessly hunt for food and defend them from predators.

Unfortunately, the Glaucous macaw isn't present in the majority of its former habitat. The disappearance of this majestic bird is probably due to the continuing trapping for the pet trade and habitat disturbance, particularly the massive removal of yatay palms which it could have gotten its main food supply. The Glaucous macaw is listed as Critically Endangered.

Breeding

Glaucous Macaws form monogamous long-term couples. Both parents are involved in the raising of their children. They breed during the dry season when food availability is at its greatest. Females lay an egg clutch of between two and three eggs, which are incubated for a period of around 28 days. Once the chicks hatch they are fed by their parents through regurgitation for the first couple of weeks of their life. The young macaws then begin to explore their surroundings and learn to eat themselves. They also learn how to fly and hunt for food.

The glaucous Macaw can be described as a extremely social bird. They are active during the day and sleep at night. During the night they often seek shelter inside tree cavities or other suitable nesting places. Their calls can be heard throughout 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 is facing numerous threats, such as the loss of habitat illegal trapping for the pet trade 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 hahns macaw for sale is also known as the Lear's macaw, or the blue-throated hummingbird. It can be distinguished by its vivid blue feathers.
