Glaucous Macaw
The glaucous Macaw is one of the world's rarest birds. It is considered Critically Endangered and could become extinct in the wild.
This bird has been reported by aviculturists from various countries however the most recent sighting was reported 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 threatened parrot species that is native South America. This magnificent bird is distinguished by the blue feather pattern and a sharp beak capable of cracking open nuts and seeds. Glaucous macaws have been known to form long-term monogamous pairs and both parents are involved in the raising of the chicks. They feed their chicks regurgitated food for the first few weeks after birth, before they begin eating solid foods as they develop. Parents also play a crucial role in teaching young macaws to fly and hunt.
The glaucous Macaw has gone extinct, but rumors about its existence persist all over the world. It is believed that the glaucous Macaw was extirpated in the 1800s because of cattle grazing and logging in yatay palm (Butia yatay) groves, where these birds mostly ate their food. It is currently believed that the glaucous Macaw has returned to captivity, where it is often raised alongside its larger relative, 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 they are known to be highly adaptable to different types of forested habitats. These beautiful birds are known to be very territorial and will defend their nesting and feeding areas from trespassers.
There have been a lot of reports involving the glaucous macaw over 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 ridiculous claim until it is substantiated with evidence. Many experts have concluded that this bird is likely extinct because there are no records from the last century. However they have been willing to accept a small chance of its survival. If it is able to survive it is highly unlikely to reach huge numbers.
Habitat
The glaucous Macaw is an impressive bird, renowned for its size and turquoise-blue coloration. Its long tail and wings highlight its graceful and agile moves. This bird is an emblem of love and loyalty. Its beak is mostly black and is distinctive in its shape. It allows it to crack open seeds and nuts, which make up a large portion of its diet.
IUCN has classified the Glaucous Macaw as Critically Endangered. It says that there is only a small population of the bird and it is at the risk of becoming extinct. The species was previously quite widespread, but today it is found only in northern Argentina and southern Paraguay and north-eastern Uruguay and Brazil from Parana state southwards, where it nestted in cliffs along major rivers.
The Glaucous Macaw was not rare in its small area, despite the fact that there was no proof of sightings since 1830. There were specimens collected until the year 1860 (in Corrientes). The last known living Glaucous Macaw was seen at the Buenos Aires Zoo in 1936 and is believed to be from Brazil.
Re-evaluation of the historical documents suggests that this species was very generalist in its habitat preferences, with a preference for areas of savanna that were interspersed with palm "islands" and areas of riparian forest along rivers. It was a particular for the consumption of palm fruits especially those of the yatay (or chatay) palm (Butia). However, it also ate ripe or 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.
Like all parrots, this bird was social, and was likely to be gregarious. It could live up to 14.8 years in captivity. It was believed to be a dependable breeder that reproduced year after year. The life expectancy of this species in the wild was between 50 and 80 years. This species was a powerful disperser of seeds, and could have contributed to the success of the Orville macaw parrot price palm yatay species in its natural habitat.
Feeding
The Glaucous Macaw (Anodorhynchus glaucus) is one of the most magnificent of all the parrot species, and its presence commands a powerful impact in its surroundings. This massive South American bird is known for its vibrant blue feathers and yellow eyes as well as the distinctive teardrop-shaped lipped sleeve that covers the lower portion of its beak.
In the past, little was known about the feeding habits and diet of the Glaucous macaw. The first detailed references I have discovered are in two books by H.W. Bates, "The Naturalist on the Amazons" first published in 1863, detailing his 11 year stay 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 have no reason to believe that they are not applicable to this species.
The Glaucous macaw is believed to have been a specialist feeder, consuming mainly 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 for agriculture and cattle ranching as well as the destruction of the yatay palm (Butia yatay) from which it could have received much of its nutrition.
In the wild, it was common to find the Glaucous macaw in subtropical forests and savannahs where palm trees were found. It was found in tree cavities, or on rocky banks or palm fronds. On average two clutches of eggs was laid and incubated by the female.
The young Glaucous Macaws are altricial, meaning they depend on their parents to care for them until they are fully fledged and can fly. Both males and females are committed to their offspring and will hunt for food and protect them against predators.
Unfortunately the Glaucous macaw has been found in its former habitat. The disappearance of this magnificent bird is probably due to the continuing trapping of pets for the pet trade, as well as disturbance of habitat, especially the wholesale removal of yatay palms where it could have gotten its main food supply. The Glaucous Macaw is classified as Critically Endangered.
Breeding
Glaucous macaws are typically monogamous couples, with both parents playing a role in raising the young. They breed during the dry season, when food availability is at its highest. The female will lay up to three eggs, which are incubated by the mother for approximately 28 days. In the initial few weeks following hatching, the chicks are fed daily by their parents through regurgitation. Then the young macaws begin to explore their surroundings and learn to eat themselves. They are also taught to fly and forage.
Like all birds, glaucous Macaws are highly social creatures. They are active during the day and spend their nights resting. They usually seek shelter in tree cavities or other nesting spots for the night. They are very vocal and their calls can be heard throughout the forest during the day.
The species is expected to rebound from the decline, but it is facing numerous threats, including habitat loss illegal trapping of the bird for the pet market, and deforestation. It is believed that there are less than 20 glaucous macaws living in the wild. The IUCN classifies the bird as "Critically Endangered, possibly extinct."
The glaucous Macaw, sometimes referred to as Lear's Macaw, or the blue-throated Hummingbird is distinguished by its vivid blue feathers. The parrot is 70 centimeters long and has an impressive beak that is capable of cracking open seeds and nuts. The beautiful bird is native to South America and can be found in diverse habitats such as forests, lowland grasslands and wetlands.
This magnificent bird is a sign of South American biodiversity. Its elegant appearance is reflected with its slim body, vibrant blue feathers, and lightweight build. Its beak is curvaceous and black, which helps it open the seeds and nuts that comprise a large portion of its diet. It's a beautiful bird, and it's often used in shows featuring birds. It is also a favourite in captivity, where it can remain for a long time.
