The 10 Most Scariest Things About Glaucous Macaw

The glaucous Macaw is one the rarest birds in the world. It is in serious danger and may even be extinct.
The bird has been reported by aviculturists across the globe, but the latest sighting was reported in 1992. The alleged sighting was reported to be in southwest 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 strong beak that is capable of breaking open seeds and nuts. Glaucous macaws form long-term monogamous families and both parents assist in raising the chicks. The chicks are fed regular food for the first couple of weeks of their lives and then a variety of solid foods as they grow. Parents are also responsible for teaching the young macaws to fly and hunt.
The glaucous Macaw has gone extinct, yet rumors of its existence persist around the world. The glaucous Macaw is believed to be extinct by the 1800s because of the logging industry and cattle grazing in yatay (Butia) palm groves where the birds gathered their food. The glaucous Macaw is believed to be making a comeback and is often kept with its larger mate, Lear's macaw.
In terms of habitat, the glaucous macaw can be found in the sub-tropical forests of South America. They are typically found in areas with abundant palm trees, and are thought to be extremely adaptable to different types of forested habitats. These beautiful birds can be territorial and defend the nesting and feeding area from intruders.
There have been a number of reports about the glaucous macaw throughout the years, but they are considered to be unreliable. The most recent report of a wild event is a friend of Ridgely's who claimed to have seen four Glaucous macaws in Califomia. This is completely untrue until it is confirmed by hard evidence. Many experts have concluded that the 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 will be extremely rare to see large numbers.
Habitat
The glaucous macaw is a striking bird, renowned for its large size and striking turquoise-blue coloration. Its long tail and wings enhance its graceful and agile movements. The bird is a symbol of loyalty and love. Its beak, which is predominantly black, is distinctive in its shape that allows it crack seeds and nuts. These are a large part of its diet.
The Glaucous Macaw is considered Critically Endangered by the IUCN and the IUCN states that it has an extremely small population and is at high chance of becoming extinct. The species was previously quite widespread, but today it is found in northern Argentina and southern Paraguay and north-eastern Uruguay and Brazil from Parana state southwards. It was a nesting place in cliffs along major rivers.
Although there haven't been any reliable sightings of this species since 1830, the Glaucous Darling hahns macaw seemed not to be extremely rare within its relatively limited range; specimens were captured from 1830 to 1860 (in Corrientes). The last known living Glaucous Macaw was exhibited 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 riparian forest bands along rivers. It was a specific feeder of palm fruits, specifically those of the yatay or chatay palm (Butia yatay) but it was likely to also consume unripe and ripe fruits, nuts, berries and vegetable matter. It nests on steep slopes on cliffs, in cliffs, and occasionally in tree cavities.
Like all parrots, this bird was social and was likely to be gregarious. It was said that it could live for up to 14.4 years in captivity and was a reliable breeder that reproduced year after year. The life expectancy of this species in the wild was perhaps about 50 to 80 years. This species was a powerful disperser of seeds and may 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 beautiful of the parrot species, and its presence commands an immense impact in its surroundings. This large South American parrot is known for its bright blue feathers, yellow eyes and the teardrop-shaped lappet on the lower part its beak.
Up until recently, very little was known about the diet of the Glaucous Macaw. The earliest detailed references I have found are in two works by H.W. Bates, "The Naturalist on the Amazons" first published in 1863 about his 11-year stay in Brazil and later in his book "As Birds of the Brazilian Forests". Both are about the Hyacinthine Macaw, Anodorhynchus Aureolarius. I have no reason to believe that they don't apply to this species.
It is probable that the Glaucous Macaw was a particular for the consumption of palm nuts. It also ate other seeds, fruits, and vegetable matter in smaller amounts. The diet of this species is likely to be influenced by the clearance of forests by early colonists for agriculture and cattle ranching, as well as the destruction of the yatay palm (Butia yatay) from which it could have gotten a lot of its diet.
In the wild in the wild, the Glaucous Macaw was commonly found in subtropical forests containing mountains and savannahs that were surrounded by palm trees, where it nestled in tree cavities and on rocky banks, or in the top of palm fronds. The female incubates and lays two eggs per.
The young Glaucous Macaws are altricial, which means they depend on their parents to care for them until they become fully fledged and can fly. Both females and males are extremely committed to their young and will constantly hunt for food and shield them from predators.
Unfortunately the Glaucous Macaw has been eradicated from most of its previous range. The disappearance of the magnificent bird is likely due to the continued trapping of birds for the pet industry as well as disturbance to habitat, particularly the massive removal of palm yatays, which may have been its main food source. The Glaucous Macaw is listed as Critically Endangered.
Breeding
Glaucous macaws are typically monogamous pairs and both parents play part in raising the young. They breed in the dry season when the availability of food is at its highest. Females lay up to three eggs, which are incubated by the mother for around 28 days. After hatching, they are fed by their parents through regurgitation for the first couple of weeks of their lives. The young macaws then begin to explore their surroundings and learn to feed themselves. They also learn to fly and hunt for food.
Like all birds, glaucous macaws are social animals. They are active during daylight hours and rest during the night. They often seek refuge in tree cavities or other nesting spots for the night. Their calls can be heard throughout the forest throughout the day.
While it is believed that the species will 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 less than 20 glaucous macaws in the wild. The IUCN classifies 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 vivid Melody blue spix macaw feathers. The parrot measures 70 centimeters long and features a powerful beaks that are capable of cracking open seeds and nuts. The beautiful bird is native to South America and can be found in a variety of habitats, including grasslands, lowland forests and wetlands.
This majestic bird is an emblem of South American biodiversity. Its elegant appearance is reflected with its slim body, vibrant blue feathers, and a light build. The black and curly beak makes it easier to crack open seeds and nuts which are a large part of its diet. It is a beautiful bird that is often seen in birds shows. It is also popular in captivity, where it can live a lifetime.
