Glaucous Macaw
The glaucous Macaw is among the rarest birds in the world. It is considered Critically Endangered, and may be extinct in the wild.
The bird has been observed by aviculturists across the globe, but the latest sighting was recorded in 1992. The alleged sighting was reported to be in southwest Paraguay close to the city of Corrientes. The bird was a male.
Origin
The Glaucous macaw is a threatened parrot species native to South America. This majestic bird is distinguished by the blue feather pattern and a strong beak capable of cracking open nuts and seeds. Glaucous macaws form long-term monogamous pairs and both parents are involved in the raising of the chicks. The chicks are fed regurgitated food for the first couple of weeks of life before being fed solid food as the chicks grow. Parents play a vital role in teaching the young macaws how to fly and forage.
The glaucous Macaw is extinct, yet rumors of its existence continue to circulate all over the world. The glaucous Macaw is believed to have been extinct in the 1800s because of logging and cattle grazing on yatay (Butia) palm groves, where the birds gathered their food. It is currently believed that the glaucous macaw returned to captivity in the wild, where it is kept with its larger cousin Lear's macaw.
In terms of habitat the glaucous macaw can be found in the sub-tropical forests of South America. They are usually found in areas that have many palm trees. They are also extremely adaptable to different types of forest environments. These beautiful birds are territorial and defend the nesting and feeding area from intruders.
There have been a variety of reports involving the glaucous macaw over the years, but many are considered to be unreliable. The most recent wild claim was made by an avicultural acquaintance of Ridgely who claimed to have seen four Glaucous Macaws in Califomia. This is a ridiculous claim until it is supported with hard evidence. The absence of any reliable records of this bird in the past century has led many experts to believe that it is extinct, however they have always been open to a remote possibility of its existence (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it is able to survive, it is extremely unlikely to make it to large numbers.
Habitat
The macaw glaucous is an impressive bird that is renowned for its large size and dazzling turquoise-blue coloration. Its wings and tail feathers are long, enhancing its graceful and agile movement. This bird is a symbol of love and loyalty. Its beak, which is primarily black, has a distinctive shape that allows it to crack seeds and nuts. They form a large part its diet.
The Glaucous Macaw is considered Critically Endangered by the IUCN which states that it has a small population and is at a high danger of disappearing. This species was once widespread however, it is now found in northern Argentina and south Paraguay and north-eastern Uruguay as well as Brazil, from Parana state to the south, where it is nestled in cliffs alongside major rivers.
While there have been no reliable sightings of this species since 1830 The Glaucous Macaw seemed not to be very rare in its comparatively small range; specimens were taken 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.
The reassessment suggests that the species is a generalist and prefers areas of savanna that are that is interspersed with palm "islands", and bands of riparian forests along rivers. It was a specialised food source for palm fruits, particularly those of the chatay or yatay palm (Butia yatay) however, it was likely to also consume ripe and unripe fruits, nuts, berries and vegetables. It nests on slopes that are steep on cliffs, in cliffs, and occasionally in tree cavities.
Like other parrots, this bird was social, and was likely to be gregarious. It was able to live up to 14.8 years in captivity and was believed to be a dependable breeder that reproduced year after year. Its life expectancy in the wild was perhaps about 50 to 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 habitats.
Feeding
The Glaucous Macaw is one of the most beautiful parrots. Its presence can have an enormous impact on its environment. This click here massive South American parrot is known for its vibrant blue feathers, bright yellow eyes, and the teardrop-shaped lipped on its lower beak.
In the past, little was known about the eating habits and 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 references to the Hyacinthine Macaw (Anodorhynchus aureolarius), but I have no reason to believe that they're not applicable to this species.
The Glaucous macaw is likely have been a specialist feeder, taking only palm nuts however, there were also tiny amounts of other seeds, fruits and vegetable matter. The diet of this species was likely heavily influenced by the clearing of forests for farming and cattle-ranching by early colonists as well as the yatay (Butia) palms from which it got a large portion of its nutrition.
In the wild the Glaucous Macaw was commonly found in subtropical forests containing the savannahs and cliffs surrounded by palm trees where it nested in tree cavities and on rocky banks or in the palm fronds' top. On average two eggs were laid in a clutch. eggs was laid and then incubated by the female.
The young Glaucous Macaws are altricial, meaning they rely on their parents to look after them until they're fully grown and able to fly. Both the males and females are very committed to their offspring and hunt for food and protect them from predators.
Unfortunately, the Glaucous macaw has been 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 habitat disturbance, particularly the wholesale removal of yatay palms which it could have gotten its main food supply. The Glaucous macaw is classified as Critically Endangered.
Breeding
Glaucous Macaws form monogamous pairs. Both parents are involved in raising their young. They breed during the dry season, when food availability is at its highest. Females lay a clutch of two to three eggs, which are incubated for about 28 days. In the initial few weeks after hatching the chicks are fed by the parents via regurgitation. The young macaws then begin to explore and to feed themselves. They are also taught how to fly and hunt for food.
The glaucous Macaw can be described as a extremely social bird. They are active during the day but sleep at night. At night, they will often seek refuge in tree cavities or other suitable nesting places. They are very vocal and their calls can be heard throughout the forest during the day.
While it is believed 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. 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 called the Lear's macaw or the blue-throated hummingbird. It can be distinguished by its bright blue feathers. The parrot measures 70 centimeters long and has powerful beaks that are capable of slicing open seeds and nuts. This gorgeous bird is native to South America and can be found in a variety of habitats such as grasslands, lowland forests and wetlands.
This magnificent bird is a sign of South American biodiversity. Its appearance is elegant, with its slender body, light build and bright blue feathers. Its black and curved beak helps it crack open nuts and seeds, which comprise a significant portion of its diet. It's a stunning bird, and it is often seen in bird shows. It is also popular in captivity, where it can live for a long time.
