Glaucous Macaw
The glaucous Macaw can be described as one of the rarest birds in the world. It is in danger of disappearing and could even be extinct.
Various 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 bird native to South America. It is threatened. This magnificent bird features a unique blue feather pattern and powerful beak that is capable of cracking open tough nuts and seeds. Glaucous macaws are known to form long-term monogamous couples and both parents assist in raising the chicks. The chicks are fed regular food during the first few weeks of life, and then solid foods as the chicks develop. Parents are also responsible for teaching young macaws to fly and hunt.
The glaucous macaw is believed to be extinct in the wild, but reports of this beautiful bird's existence are still spreading across the globe. The Glaucous Macaw is believed have gone extinct in the 1800s due to cattle grazing on yatay (Butia) palm groves from which the birds would gather their food. It is believed that the glaucous macaw made a comeback in captivity in the wild, where it is raised alongside its larger relative Lear's macaw.
The glaucous Macaw lives in subtropical rainforests of South America. They are most often found in areas with abundant palm trees, and they are known to be highly adaptable to different types of forested habitats. These beautiful birds can be territorial and defend the nesting and feeding area from intruders.
Over the years there have been many reports of the glaucous macaw however they are generally considered unreliable. The most recent wild claim was reported by an avicultural friend of Ridgely who claimed to have seen four Glaucous Macaws in Califomia. This claim is untrue until it is supported with hard evidence. Many experts have concluded that this bird is likely extinct because there are no records from the last century. However they have always been willing accept a remote chance of its survival. If it does survive, it is extremely unlikely to reach huge numbers.
Habitat
The glaucous macaw is a striking bird that is renowned for its size and striking turquoise-blue coloration. The tail feathers and wings are long, enhancing its graceful and agile moves. The bird is a symbol of loyalty and love. Its beak is mostly black, and it has a distinctive shape that allows it to open seeds and nuts which comprise a large part of its diet.
The Glaucous Macaw is considered Critically Endangered by the IUCN, which notes that it is a small population and is at a high risk of extinction. The species was once widespread, but is now only found in northern Argentina south Paraguay and north-eastern Uruguay and Brazil from Parana state to south, where it nests in cliffs alongside major rivers.
Although there haven't been any confirmed sightings of this species since 1830 The Glaucous Macaw seemed not to be very rare in its relatively limited range; specimens were taken until 1860 (in Corrientes). The last known living Glaucous Macaw was displayed at the Buenos Aires Zoo in 1936 and is believed to be from Brazil.
The reassessment suggests that the species is a generalist, and prefers savanna habitat interspersed with palm "islands", and riparian forest bands along river systems. It was a particular feeder of palm fruit particularly those of the yatay (or chatay) palm (Butia). However, it also ate ripe and unripe fruits and berries, nuts, and vegetable matter. It nestled on slopes and cliffs, sometimes in tree cavities, and laid an average clutch of two eggs.
This bird was likely gregarious and social, similar to other parrots. It was able to live up to 14.8 years in captivity and was said to be a dependable breeder that reproduced year after year. In the wild, the lifespan was probably between 50 and 80 years. The species was a strong disperser of seeds and could be a factor in the success of the palm yatay in its natural habitats.
Feeding
The Glaucous Macaw (Anodorhynchus glaucus) is one of the most magnificent of all the species of parrots, and its presence commands an enormous impact on its surroundings. This massive South American parrot is known for its vibrant blue feathers, yellow eyes, and the teardrop-shaped lipped on the lower part its beak.
Until recently very little was known about eating habits 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 stay in Brazil. Later, in his book "As Birds of the Brazilian Forests" He wrote about the same experience. Both of these are about the Hyacinthine Macaw (Anodorhynchus aureolarius) However, I have no reason to believe that they're not applicable to this species.
The Glaucous macaw is believed to be a specialized eater, consuming only palm nuts as well as tiny amounts of other seeds, fruits and vegetable matter. The diet of this species was likely influenced by the clearing of forests to cultivate cattle and the cattle-ranching practices of early colonists, as well the felling of yatay (Butia) palms from which it got a large portion of its nutrition.
In the wild, it was common to see the Glaucous macaw in savannahs and subtropical forests in which palm trees were present. It hid in tree cavities or on rocky banks or palm fronds. On average two eggs were laid in a clutch. eggs was laid and incubated by the female.
The young Glaucous Macaws rely on their parents for care until they are able to fly and are fully grown. Both the males and females are committed to their offspring and will hunt for food and protect them against predators.
Unfortunately the Glaucous macaw has been found in most of its former habitat. The disappearance of this magnificent bird is probably due to the ongoing trapping for the pet trade, as well as disturbance to habitat, specifically the mass removal of yatay palms which it could have gotten its primary food source. The Glaucous Macaw is listed as Critically Endangered.
Breeding
Glaucous macaws typically form long-term monogamous pairs, with both parents playing part in raising the young. They breed in the dry season when the availability of food is at its greatest. more info The female will lay two to three eggs which are incubated by the mother for around 28 days. For the first few weeks after hatching the chicks are fed by the parents through regurgitation. The young macaws then begin to explore their surroundings and begin to learn to eat themselves. They are also taught how to fly and forage.
The glaucous Macaw can be described as a extremely social bird. They are active during the day and spend their nights resting. During the night they usually seek refuge inside tree cavities or other nesting areas that are suitable. They are extremely vocal and their calls can be heard throughout the forest during the day.
The species is expected to rebound from the decline, however it is facing numerous threats, including habitat loss illegal trapping of the bird for pet trade, and deforestation. It is estimated that there are only about 20 glaucous macaws that are in the wild. The IUCN has classified 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 bright blue feathers. It is a large bird, measuring 70 centimeters long and has a sturdy beak that is able to break open hard nuts and seeds. The beautiful bird is native to South America and can be found in various habitats, including grasslands, lowland forests and wetlands.
This majestic bird is an emblem of South American biodiversity. Its elegant appearance with its slim body, light build and vivid blue feathers. The black and curly beak makes it easier to crack open seeds and nuts, which comprise a significant portion of its diet. It is a stunning bird that is often seen in birds shows. It is also popular in captivity where it can live for a long time.
