Glaucous Macaw
The glaucous Macaw is one of the rarest birds on earth. It is Critically Endangered and could be extinct in the wild.
This bird has been reported by aviculturists across the globe, but the latest sighting was in 1992. This alleged sighting occurred in the southwestern region of Paraguay, near the city of Corrientes. The bird was male.
Origin
The Glaucous Macaw is a bird native to South America. It is threatened. This magnificent bird has a distinctive blue feather pattern and a strong beak that is capable of breaking open hard seeds and nuts. Glaucous Macaws are monogamous pair and both parents care for the chicks. The chicks are fed regular food during the first few weeks of life and then a variety of solid foods as the chicks develop. Parents are also responsible for teaching the young macaws to fly and hunt.
The glaucous Macaw has gone extinct, but rumors about its existence persist around the world. It is estimated that the glaucous Macaw was extinct in the 1800s because of logging and cattle grazing of yatay palm (Butia yatay) groves, where these birds primarily gathered their meals. It is believed that the glaucous macaw has returned to captivity, where it is often kept alongside its larger cousin Lear's macaw.
The glaucous Macaw is found in sub-tropical rainforests in South America. They are usually found in areas with many palm trees. They are also highly adaptable to a variety of forest habitats. These beautiful birds can be territorial and defend the nesting and feeding area from intruders.
Over the years there have been numerous reports on the glaucous Macaw, but they are generally considered unreliable. The most recent wild claim was made by an avicultural friend of Ridgely who claimed to have seen four Glaucous Macaws in Califomia. This claim is unacceptable until it is substantiated by solid evidence. The absence of any credible evidence of this bird in the past century has led many experts to believe that it is extinct, but they have always been open to the possibility of survival (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it does survive it will be extremely uncommon to witness large numbers.
Habitat
The macaw with the glaucous is a striking bird that is known for its size and striking turquoise-blue coloration. Its wings and tail feathers are long, enhancing its graceful and agile moves. This bird is an emblem of love and loyalty. Its beak, which is predominantly black, is distinctive in its shape that allows it crack nuts and seeds. They form a large portion of its diet.
IUCN has classified the Glaucous Macaw as Critically Endangered. It notes that there is only a small population of this bird, and that it is at a high-risk of extinction. The species was once quite widespread, but today it is only found in northern Argentina as well as southern Paraguay, north-eastern Uruguay and Brazil from Parana state southwards where it was a nesting place in cliffs along major rivers.
The Glaucous Macaw was not rare in its limited range, even though there were no reliable sightings since 1830. There were specimens taken up until the year the year 1860 (in Corrientes). The last living Glaucous Macaw, believed to be from Brazil, was exhibited in the Buenos Aires Zoo back in 1936.
The reassessment suggests that the species is a generalist and prefers savanna habitat that is interspersed with palm "islands", and riparian forest bands along river systems. It was a specialist feeder of palm fruit especially those of the yatay (or chatay) palm (Butia). However it also ate ripe and unripe fruits and berries, nuts, and other vegetable matter. It nests on slopes that are steep or in cliffs, and also in tree cavities.
This bird was likely to be gregarious and social, just like other parrots. It was reported that it could live to 14.4 years in captivity, and was a reliable breeder who reproduced year after year. In the wild, the lifespan was probably between 50 and 80 years. This species was a potent seed disperser and may have contributed to the success of the yatay palm in its native habitats.
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 environment. This large South American parrot is known for its bright blue feathers, bright yellow eyes, and the teardrop-shaped lipped on the lower part its beak.
Up until recently, very little was known about the feeding habits and diet of the Glaucous macaw. The first detailed references I have found are in two works by H.W. Bates, "The Naturalist on the Amazons" first published in 1863 on 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're not applicable to this species.
The Glaucous macaw is believed to be a specialized feeder, taking only palm nuts, but also small amounts of other fruits, seeds and vegetable matter. The diet of this species is likely to be influenced by the clearance of forests by early colonists to cultivate and cattle ranching, as well as the destruction of the yatay palm (Butia yatay) from which it could have gotten a lot of its nutrition.
In the wild, it was common to see the Glaucous macaw in subtropical forests and savannahs in which palm trees were present. It hid in tree cavities, or on rocky banks and palm fronds. On average two clutches of eggs was laid and then incubated by the female.
The young Glaucous Macaws rely on their parents for care until they can fly and fully fledged. Both the male and female are extremely committed to their offspring and will continuously hunt for food and shield them from predators.
Unfortunately the Glaucous Macaw has been eliminated from the majority of its former range. The disappearance of this majestic bird is probably due to the ongoing trapping of pets for the pet trade as well as disturbance to habitat, specifically the mass removal of yatay palms which it could have gotten its main food supply. The Glaucous macaw is listed under Critically Endangered.
Breeding
Glaucous Macaws are monogamous, long-term couples. Both parents are involved in raising their young. They breed during the dry season when the availability of food is at its greatest. The female will lay up 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 via regurgitation. The young macaws then begin to explore and learn to feed themselves. They are also taught to fly and forage.
The glaucous Macaw is very social bird. They are active during daylight hours and rest during the night. During the night they usually seek shelter inside tree cavities or other suitable nesting places. They are very vocal and their calls can be heard throughout the Buy Macaw forest during the day.
Although it is hoped the species will recover from its decline in the wild, the bird is facing many threats, including loss of habitat and illegal trapping for pet trade and deforestation. Only about 20 glaucous Macaws are believed to exist in the wild. The IUCN classifies the bird as "Critically Endangered - possibly Extinct."
The glaucous macaw is also known as the Lear's macaw or blue-throated hummingbird. It can be distinguished by its vivid blue feathers. It is a large parrot measuring 70 centimeters long and features a robust beak that can crack open seeds and nuts that are tough to break. This gorgeous bird is native to South America, and it is found in a variety of habitats such as grasslands, forests, dry lowland, and wetland.
This magnificent bird is a symbol of South American biodiversity. It has a regal look with its slim body, vibrant blue feathers and its light build. The black and curly beak helps it crack open seeds and nuts, which make up a significant 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.
