Glaucous Macaw
The glaucous Macaw can be described as one of the rarest birds in the world. It is critically endangered and could be extinct.
The bird has been reported by aviculturists from various countries 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 male.
Origin
The Glaucous macaw is a threatened parrot species native to South America. This magnificent bird is distinguished by blue feathers, and a sharp beak that is capable of breaking open nuts and seeds. Glaucous Macaws live in monogamous pairs and both parents tend the chicks. The chicks are fed regurgitated food during the first few weeks of life and then a variety of solid foods as the chicks grow. Parents also play a vital role in teaching young macaws to fly and forage.
The glaucous macaw is considered 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 to be extinct by the 1800s due to logging and cattle grazing on yatay (Butia) palm groves from which the birds gathered their food. It is believed that the glaucous macaw has made a comeback in captivity, where it is often raised alongside its larger relative Lear's macaw.
The glaucous Macaw lives in sub-tropical rainforests of South America. They are usually located in areas that have many palm trees. They are also very adaptable to various types of forest habitats. These beautiful birds are known to be very territorial and will protect their feeding and nesting areas from intruders.
There have been a lot of reports on the glaucous macaw throughout the years, but they are considered to be not reliable. The most recent wild claim was made by an avicultural friend of Ridgely who claimed to have spotted four Glaucous Macaws in Califomia. This is a completely absurd claim until it is verified with hard evidence. The absence of any reliable records of this bird in the past century has led many experts to think that it's likely extinct, yet they have always been willing to accept a remote possibility of its survival (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it survives, it will be extremely uncommon to see large numbers.
Habitat
The glaucous Macaw is an impressive bird, well-known for its size and turquoise-blue coloring. The tail and wings are long, enhancing its graceful and agile movements. This bird is also an emblem of affection and loyalty. Its beak, which is primarily black, has a distinct shape that allows it to break seeds and nuts. These are 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 in risk of extinction. The species was previously relatively widespread, but it is found only in northern Argentina and southern Paraguay, north-eastern Uruguay and Brazil from Parana state southwards where it nestted in cliffs along major rivers.
While there have been no confirmed sightings of this species since 1830 however, the Glaucous Macaw seemed not to be very rare in its comparatively small range; specimens were captured up to 1850 (in Corrientes). The last known living Glaucous Macaw was displayed at the Buenos Aires Zoo in 1936 and is believed to be from Brazil.
Re-evaluation of the historical records suggests that this species was a rather generalist in its preferences for habitat with a preference for savanna habitat intermingled with palm "islands" and forests of riparian along river systems. 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 vegetable matter. It nested on steep slopes and cliffs, occasionally in tree cavities and laid an average clutch of two eggs.
As with other parrots this bird was social and probably gregarious. It was believed that it could live for up to 14.4 years in captivity and was a reliable breeder that reproduced year after. The life expectancy of this species in the wild was 50-80 years. The species was a strong disperser of seeds, and could have contributed to the success of the palm yatay species in its natural habitat.
Feeding
The Glaucous Macaw (Anodorhynchus glaucus) is one of the most beautiful of the parrot species and its presence has an enormous impact on its surroundings. This huge South American bird is known for its vibrant blue feathers and eyes that are yellow, and also for its distinctive teardrop-shaped lappet that brackets the lower portion of its beak.
In the past, little was known about diet 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 work "As Birds of the Brazilian Forests". Both of these are about the Hyacinthine Macaw (Anodorhynchus aureolarius) however I see no reason to think that they are not applicable to this species.
The Glaucous macaw is likely to be a specialized eater, consuming only palm nuts, but also tiny amounts of other fruits, seeds and vegetable matter. The diet of this species is likely to have been affected by the clearing of forests by the early colonists for agriculture and cattle ranching as well as the felling of the yatay palm (Butia yatay) from which it could have gotten its majority of its diet.
In the wild in the wild, the Glaucous Macaw was commonly found in subtropical forests with the savannahs and cliffs surrounded by palm trees where it nested in tree cavities and on rocky banks or in the palm fronds' top. The female incubates and lays two eggs per.
The young Glaucous Macaws are altricial, meaning they depend on their parents to care for them until they are fully grown and fly. Both the male and female are extremely committed to their young and will continuously hunt for food and defend them from predators.
Unfortunately, the Glaucous macaw has been found in most of its former habitat. The disappearance of this magnificent bird is likely due to continued trapping for the pet industry and habitat disruption, especially the wholesale removal of palm yatays, which could have been their primary food source. The Glaucous macaw is listed under Critically Endangered.
Breeding
Glaucous macaws usually form long-term monogamous pairs, with both parents playing part in raising the young. They breed during the dry season, when food availability is at its highest. The female lays an egg clutch that ranges from two to three eggs that are incubated for about 28 days. For the first few weeks following hatching, the chicks are fed by their parents through regurgitation. Then the young macaws begin to explore their surroundings and begin to learn to eat themselves. They also learn how to fly and hunt for food.
The glaucous Macaw is a highly social bird. They are active during the day but are restful at night. During the night, they will often seek refuge in tree cavities or other nesting areas that are suitable. Their calls can be heard throughout the forest throughout the day.
Although it is hoped 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 estimated that there are only about 20 glaucous check here 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 the blue-throated Hummingbird, is distinguished by its bright blue feathers. It is a large parrot with a length of 70 centimeters and features a robust beak that can crack open seeds and nuts that are tough to break. The beautiful bird is native to South America and can be found in various habitats that include grasslands, lowland forests and wetlands.
This magnificent bird is a sign of South American biodiversity. It has a regal look with its slender body, bright blue feathers, and lightweight build. Its beak is curved and black, which aids it open the seeds and nuts that comprise a large portion of its diet. It's a beautiful bird, and it's often featured in bird shows. It is also popular in captivity where it can live a lifetime.
