Glaucous Macaw
The glaucous Macaw is one of the rarest birds in the world. 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. The alleged sighting was reported to have occurred in southwestern Paraguay, near the city of Corrientes. The bird was male.
Origin
The Glaucous Macaw is a parrot native to South America. It is endangered. This magnificent bird is distinguished by the blue feather pattern and a sharp beak capable of cracking open seeds and nuts. Glaucous macaws have been known to form long-term monogamous pairs and both parents are involved in the raising of the chicks. They feed the chicks regurgitated food for the first few weeks after birth, and then they begin to eat solid food as they grow. The parents also play a vital role in teaching young macaws to fly and forage.
The glaucous Macaw is extinct, but rumors about its existence persist around the world. It is estimated that the glaucous macaw extirpated in the 1800s because of cattle grazing and logging in yatay palm (Butia yatay) areas, where the birds typically gathered their food. It is believed that the glaucous macaw returned to captivity, where it is often raised alongside its larger relative Lear's macaw.
The glaucous Macaw lives in sub-tropical rainforests of South America. They are typically located in areas that have numerous palm trees. They are also known to be very adaptable to various types of forested environments. These beautiful birds are territorial and will defend the nesting and feeding areas from intruders.
There have been Ziggy Our Scarlet Macaw of reports involving the glaucous macaw through the years, but most are considered to be not reliable. The most recent wild claim was made by an avicultural acquaintance of Ridgely who claimed to have spotted 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 past century has been a reason for many experts to believe that it is extinct, however they have always been open to the possibility of survival (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it does survive, it is extremely unlikely to make it to huge numbers.
Habitat
The glaucous Macaw is an impressive bird, well-known for its large size and turquoise-blue coloring. The tail and wings are long, enhancing its fluid and graceful moves. The bird is also an emblem of love and loyalty. Its beak is primarily black and is distinctive in its shape. It allows it to break open seeds and nuts, which make up a large part of its diet.
IUCN has classified the Glaucous Macaw as Critically Endangered. It says that there is a small population of the bird and it is in high-risk of extinction. The species was once fairly widespread but now 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.
Although there have been no reliable sightings of this species since 1830, the Glaucous Macaw seemed not to be a rare species in its relatively limited range; specimens were captured until 1850 (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.
Re-evaluation of the historical documents suggests that this species was very generalist in its preferences for habitat and preferred areas of savanna that were interspersed with palm "islands" and bands of riparian forest 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, nuts, berries, and other vegetable matter. It nestled on slopes and cliffs, sometimes in tree cavities, and laid an average clutch of two eggs.
As with other parrots this bird was social, and was probably gregarious. It was said that it could live up to 14.4 years in captivity and was a reliable breeder who reproduced year after year. In the wild, its lifespan was probably between 50 and 80 years. This species was a potent disperser of seeds and may have contributed to the success of the palm yatay in its natural habitats.
Feeding
The Glaucous Macaw is one of the most stunning parrots. Its presence has a strong impact on the environment. This massive South American parrot is known for its vibrant blue feathers, yellow eyes and the teardrop-shaped lappet on the lower part 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 works by H.W. Bates' "The Naturalist on Amazons" which was first published in 1863, which describes his 11-year stay in Brazil. In his later book "As Birds of the Brazilian Forests" He wrote about the same experience. Both of these refer to the Hyacinthine Macaw (Anodorhynchus aureolarius), but I have no reason to believe that they're not applicable to this species.
It is likely that the Glaucous Macaw was a specialist in the consumption of palm nuts, and also took other seeds, fruits, and vegetable matter in small amounts. The diet of this species was likely affected by the clearing of forests for agriculture and cattle-ranching by early colonists, as well the felling of yatay (Butia) palms from which it 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 present. It nestled in tree cavities, or on rocky banks or palm fronds. Ziggy Our Scarlet Macaw and lays two eggs per.
The young Glaucous Macaws rely on their parents for their care until they are able to fly and are fully grown. Both males and females are very dedicated to their offspring, and will hunt for food and defend them from predators.
Unfortunately, the Glaucous Macaw has been eradicated from the majority of its previous range. The disappearance of this magnificent bird is likely due to continued trapping for the pet industry as well as habitat disruption, especially the massive removal of palm yatays that could have been their primary food source. The Glaucous Macaw is classified as Critically Endangered.
Breeding
Glaucous Macaws are monogamous, long-term pair. Both parents are involved in the raising of their children. They breed during the dry season, when food is plentiful. The female lays two to three eggs which are incubated by the mother for about 28 days. After hatching, they are fed by their parents via regurgitation during the first few weeks of their life. Macaws are then able to explore and learn to feed themselves. They also learn how to fly and forage.
Like all species of birds, glaucous macaws are social animals. They are active during daylight hours, and take a break at night. They often seek refuge in cavities in trees or other nesting spots for the night. 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 many threats, including loss of habitat illegal trapping for the pet trade, and deforestation. It is believed that there are only about 20 glaucous macaws living in the wild. The IUCN classifies the bird as "Critically Endangered--Possibly Extinct."
The glaucous Macaw is also known as Lear's Macaw, or the blue-throated Hummingbird is distinguished by its bright blue feathers. It is a large parrot measuring 70 centimeters in length, and has a strong beak that can crack open seeds and nuts that are tough to break. This gorgeous bird is native to South America, and it is found in a variety of habitats such as forests, dry lowland grasslands and wetland.
This majestic bird is a symbol of South American biodiversity. It has a regal appearance, with its slender body, light build, and vibrant blue feathers. The black and curly beak helps it crack open nuts and seeds, which make up a significant part of its diet. It's a beautiful bird, and it is often used in bird shows. It is also a popular bird in captivity, where it could remain for a long time.
