Glaucous Macaw
The glaucous macaw is one of the rarest birds in the world. It is Critically Endangered and could become extinct in the wild.
This bird has been reported by aviculturists in various countries however the most recent sighting was reported in 1992. The reported sighting was in the southwestern region of Paraguay, near the city of Corrientes. The bird was male.
Origin
The Glaucous macaw is an endangered parrot species native to South America. This magnificent bird is characterized by blue feathers, and a powerful beak capable of cracking open seeds and nuts. Glaucous Macaws live in monogamous pairs and both parents tend the chicks. They feed their chicks regurgitated food for the first few weeks after birth, before they begin to eat solid foods as they develop. The parents also play a crucial role in teaching the young macaws how to fly and hunt.
The glaucous Macaw has gone extinct, yet rumors of its existence continue to spread around the world. It is estimated that the glaucous macaw was extinct in the 1800s due to cattle grazing and logging in yatay palm (Butia yatay) groves, where these birds typically gathered their food. The Glaucous Macaw is believed have returned, and is often kept along with its larger mate, Lear's macaw.
The glaucous Macaw can be found in sub-tropical rainforests of South America. They are typically located in areas with a lot of palm trees, and they are believed to be extremely adaptable to different types of forested habitats. These beautiful birds are recognized as being very territorial and will protect their nesting and feeding areas from invaders.
Over the years there have been numerous reports on the glaucous Macaw, but they are generally considered unreliable. The most recent claim of a wild occurrence involves an avicultural acquaintance of Ridgely's who claimed to have observed four Glaucous macaws in Califomia. This is a completely absurd claim until it is confirmed with hard evidence. Many experts have concluded that this bird is likely to be extinct since there are no records in the last century. However they have been willing accept a remote chance of its survival. If it is able to survive it will be extremely rare to see large numbers.
Habitat
The macaw glaucous is an impressive bird that is renowned for its size and striking turquoise-blue coloration. The long tail and wings enhance its graceful and agile movements. The bird is an emblem of love and loyalty. Its beak is predominantly black, and it has a unique shape that allows it to open seeds and nuts, which constitute a significant 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 that it is at a high-risk of extinction. The species was once widespread, but is now only 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 that run alongside major rivers.
The Glaucous Macaw was not rare in its small range, despite the fact that there was no evidence of sightings since 1830. There were specimens collected until the year 1860 (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 more generalist in its preferences for habitat and preferred savanna habitat intermingled with palm "islands" and areas of riparian forest along river systems. It was a specialized in the consuming of palm fruit especially those of the yatay (or chatay) palm (Butia). However, it also ate ripe or unripe fruits and berries, nuts, and other vegetable matter. It nested on steep slopes and cliffs, occasionally in tree cavities and laid an average clutch of two eggs.
The bird was likely to be gregarious and social, similar to other parrots. It was reported that it could live up to 14.4 hythian macaw for sale years in captivity, and was a reliable 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 be a factor in the success of the palm yatay in its natural habitat.
Feeding
The Glaucous Macaw is one of the most stunning parrots. The presence of this parrot has a strong impact on its environment. This huge South American bird is known for its vibrant blue feathers and yellow eyes, as well as the distinctive teardrop-shaped lappet which adorns the lower portion of its beak.
Until recently very little was known about the diet of the Glaucous Macaw. The first detailed references I have come across are two works by H.W. Bates, "The Naturalist on the Amazons" first published in 1863 on 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. There is no reason to think that they could not apply to this species.
The Glaucous macaw is likely to be a specialist feeder, consuming mainly palm nuts as well as small amounts of other seeds, fruits and other matter. The diet of this species is likely to have been influenced by the clearance of forests by the early colonists to cultivate and cattle ranching, as well as the removal of the yatay palm (Butia yatay) from which it could have gotten a lot of its nutrition.
In the wild in the wild, the Glaucous Macaw was found in subtropical forests that had the savannahs and cliffs surrounded by palm trees where it nested in tree cavities and on rocky banks or in the top of 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 become fully grown and able to fly. Both males and females are extremely dedicated to their offspring and constantly hunt for food and protect them from predators.
Unfortunately unfortunately, the Glaucous macaw has been found in most of its former habitat. The disappearance of this majestic bird is probably due to the ongoing trapping of pets for the pet trade as well as disturbance to habitat, specifically the massive clearing of yatay palms from which it may have obtained its main food supply. The Glaucous macaw is classified as Critically Endangered.
Breeding
Glaucous Macaws form monogamous couples. Both parents are involved in raising their young. They breed during the dry season when the availability of food is at its greatest. Females lay an egg clutch of between two and three eggs, which are incubated for around 28 days. In the initial few weeks following hatching, the chicks are fed daily by their parents via regurgitation. Then the young macaws begin to explore their surroundings and learn how to feed themselves. They also learn to fly and hunt for food.
The glaucous Macaw can be described as a very social bird. They are active during the day but spend their nights resting. They often seek refuge 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 faces many threats including habitat loss illegal trapping of the bird to sell on the pet market and deforestation. About 20 glaucous macaws are believed to be in the wild. The IUCN has classified the bird as "Critically endangered, possibly extinct."
The glaucous macaw is known as the Lear's macaw or blue-throated hummingbird. It is distinguished by its bright blue feathers. It is a large parrot, measuring 70 centimeters in length and features a robust beak that can break open tough nuts and seeds. This gorgeous bird is native to South America, and it can be found in many habitats like forests, dry lowland grasslands and wetland.
This magnificent bird is an emblem of South American biodiversity. Its elegant appearance, with its slender build, lightweight body and bright blue feathers. The beak is curved and black, which helps it break open the nuts and seeds that comprise a large portion of its diet. It is a beautiful bird and is often used in birds shows. It is also popular in captivity where it can live for a lifetime.
