Glaucous Macaw
The glaucous macaw is one of the rarest birds in the world. It is Critically Endangered and could be extinct in the wild.
The bird has been observed by aviculturists from various countries However, the most recent sighting was in 1992. This alleged sighting was in southwest Paraguay close to 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 is distinguished by a blue feather pattern, and a strong beak that can break open seeds and nuts. Glaucous macaws have been known to form long-term monogamous couples and both parents are involved in the raising of the chicks. The chicks are fed regular food during the first few weeks of life, and then solid foods as the chicks develop. Parents also play a vital role in teaching young macaws to fly and hunt.
The glaucous Macaw has gone extinct, yet rumors of its existence persist across the globe. It is estimated that the glaucous macaw extinct in the 1800s due to cattle grazing and logging in yatay palm (Butia yatay) groves, where these birds mostly ate their food. The glaucous Macaw is believed to have made a comeback, and is often kept with its larger cousin, Lear's macaw.
The glaucous Macaw lives in subtropical rainforests of South America. They are typically located in areas with numerous palm trees. They are also very adaptable to various types of forest habitats. These beautiful birds are also known to be very territorial and will protect their nesting and feeding areas from invaders.
In the past, 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 is a completely absurd claim until it can be verified with hard evidence. The lack of any acceptable data on this bird over the last century has been a reason for many experts to conclude that it is likely extinct, but they have always accepted an extremely remote possibility of its existence (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it survives it is highly unlikely to reach huge numbers.
Habitat
The macaw glaucous is an impressive bird that is renowned for its huge size and dazzling turquoise-blue coloration. The tail feathers and wings are long, which enhances its graceful and agile moves. This bird is also a symbol of loyalty and love. Its beak is predominantly black and has a unique shape that allows it to crack open seeds and nuts which comprise a large portion of its diet.
IUCN has classified the Glaucous Macaw as Critically Endangered. It notes that there is a small population of the bird, and that it is at a the risk of becoming extinct. The species was once widespread but is now found in northern Argentina south Paraguay and north-eastern Uruguay and Brazil from Parana state to the south, where it resides in cliffs along major rivers.
Although there haven't been any credible sightings of the species since 1830, the Glaucous Macaw seemed not to be a rare species in its comparatively small range; specimens were taken from 1830 to 1850 (in Corrientes). The last living Glaucous Macaw, believed to originate from Brazil was displayed in the Buenos Aires Zoo back in 1936.
A re-examination of the historical documents suggests that this species was a very generalist in its preferences for habitat with a preference for areas of savanna that were interspersed with palm "islands" and forests of riparian along rivers. It was a particular feeder of palm fruit, especially those of the yatay (or chatay) palm (Butia). However it also ate ripe and unripe fruits as well as berries, nuts and even vegetable matter. It is a nesting place on steep slopes or in cliffs, and also in tree cavities.
Like all parrots, this bird was social, and was likely to be gregarious. It was reported that it could live for up to 14.4 years in captivity, and was a reliable breeder who reproduced year after year. Its life expectancy in the wild was perhaps 50-80 years. The species was a strong disperser of seeds and may have contributed to the success of the palm yatay species in its natural habitats.
Feeding
The Glaucous Macaw (Anodorhynchus glaucus) is among the most stunning of the species of parrots, and its presence commands an enormous impact on its surroundings. This massive South American bird is known for its vibrant blue feathers and yellow eyes and also for its distinctive teardrop-shaped lipped sleeve that covers the lower portion of its beak.
Until recently very little was known about the eating habits of the Glaucous Macaw. The first references to the subject I have found are in two publications by H.W. Bates, "The Naturalist on the Amazons" first published in 1863 on his 11 year stay in Brazil and later in his work "As Birds of the Brazilian Forests". Both are about the Hyacinthine Macaw, Anodorhynchus Aureolarius. There click here is no reason to believe that they do not apply to this species.
It is likely that the Glaucous Macaw was a particular in the consumption of palm nuts, and also took other seeds, fruits, and vegetable matter in smaller quantities. The diet of this species is likely to have been influenced by the clearance of forests by early colonists to cultivate and cattle ranching and the felling of the yatay palm (Butia yatay) from which it may have received much of its food.
In the wild the Glaucous Macaw was found in subtropical forests with the savannahs and cliffs surrounded by palm trees, where it nested in tree cavities and on rocky banks or the top of palm fronds. On average, a clutch of two eggs was laid and then incubated by the female.
The young Glaucous Macaws rely on their parents for care until they fly and become fully full fledged. Both the male and female are extremely committed to their offspring and tirelessly hunt for food and defend them from predators.
Unfortunately, the Glaucous macaw isn't found in its former habitat. The disappearance of this majestic bird is most likely due to the continuing trapping of pets for the pet trade as well as disturbance to habitat, specifically the wholesale clearing of yatay palms from which it may have obtained its primary food source. The Glaucous macaw is classified as Critically Endangered.
Breeding
Glaucous macaws are typically monogamous pairs, with both parents playing an active role in the raising of the young. They breed during the dry season, when the availability of food is at its highest. The female lays a clutch of two to three eggs that are incubated for about 28 days. In the initial few weeks following hatching, the chicks are fed daily by their parents through regurgitation. The young macaws begin to explore and learn to feed themselves. They are also taught how to fly and forage.
The glaucous Macaw is highly social bird. They are active during daylight hours and rest at night. In the evening, they will often seek refuge in tree cavities or other nesting areas that are suitable. Their calls can be heard in the forest throughout the day.
The species is expected to recover from its decline, however it is facing numerous threats, including habitat loss, illegal trapping of the bird to sell on the pet market and deforestation. Only about 20 glaucous Macaws are believed to exist 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 vibrantly blue feathers. The parrot measures 70 centimeters long and has an impressive beak that is capable of slicing open nuts and seeds. This gorgeous bird is native to South America and can be found in a variety of habitats that include grasslands, lowland forests and wetlands.
This majestic bird is an emblem of South American biodiversity. Its appearance is elegant, with its slender body, light weight and bright blue feathers. Its black and curved beak allows it to break open seeds and nuts, which make up a significant part of its diet. It's a beautiful bird, and is often seen in shows featuring birds. It is also a favourite in the wild, where it can remain for a long time.
