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 However, the most recent sighting was in 1992. The alleged sighting was reported to have occurred in southwestern Paraguay close to the city of Corrientes. The bird was male.
Origin
The Glaucous macaw is a threatened parrot species that is native to South America. This magnificent bird is distinguished by the blue feather pattern and a sharp beak that is capable of breaking open nuts and seeds. Glaucous Macaws live in monogamous pair and both parents tend the chicks. They feed the chicks regurgitated food for the first couple of weeks after birth, and then they begin eating solid food as they grow. Parents are also responsible for 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 due to logging and cattle grazing of yatay palm (Butia yatay) groves, where these birds primarily gathered their meals. It is believed that the glaucous Macaw has returned to captivity and is usually 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 most often found in areas with abundant palm trees, and are known to be highly adaptable to various types of forested habitats. These beautiful birds can be territorial and will protect the feeding and nesting area from intruders.
There have been a number of reports involving the glaucous macaw over the years, but most are considered to be not reliable. The most recent wild claim was made by an avicultural friend of Ridgely who claimed to have seen four Glaucous Macaws in Califomia. This claim is completely unacceptable until it is verified with hard evidence. The absence of any credible records of this bird in the past century has been a reason for many experts to believe that it is extinct, but they have always accepted an extremely remote possibility of its existence (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it does survive, it is extremely unlikely to be seen in huge numbers.
Habitat
The macaw with the glaucous is a striking bird that is known for its size and dazzling turquoise-blue coloration. The tail and wings are long, which enhances its graceful and agile movements. This bird is a symbol of loyalty and love. Its beak, which is mostly black, has a distinct shape and allows it to crack seeds and nuts. They are a significant part its diet.
IUCN has classified the Glaucous Macaw as Critically Endangered. It says that there is only a small population of this bird and it is at high-risk of extinction. The species was once quite widespread, but today it is found only in northern Argentina and southern Paraguay, north-eastern Uruguay and Brazil from Parana state southwards where it was a nesting place in cliffs along major rivers.
The Glaucous Macaw was not rare in its relatively small area, even though there was no evidence of sightings after 1830. The specimens were taken up until the year 1850 (in Corrientes). The last known living Glaucous Macaw was seen at the Buenos Aires Zoo in 1936 and is believed to be from Brazil.
Reassessment suggests that this species is a generalist, preferring the savanna habitat, which is which is surrounded by palm "islands" and riparian forest bands along rivers. It was a specialised eater of palm fruits, particularly those of the chatay palm (Butia yatay) but it was also likely to consume ripe and unripe fruit such as berries, nuts, and vegetables. It nested on steep slopes and cliffs, occasionally in tree cavities and laid an average clutch of two eggs.
Like other parrots, this bird was social and probably gregarious. It was believed that it could live for up to 14.4 years in captivity, and was a reliable breeder who reproduced year after year. The life expectancy of this species in the wild was between 50 and 80 years. This species was a powerful seed disperser, and could have contributed to the success of the yatay palm within its natural habitats.
Feeding
The Glaucous Macaw (Anodorhynchus glaucus) is among the most beautiful of the parrot species and has a an immense impact in its environment. This large South American parrot is known for its vibrant blue feathers, yellow eyes and the teardrop-shaped lappet on the lower part its beak.
In the past, little was known about eating habits and diet of the Glaucous macaw. The first references to the subject I have discovered are in two books by H.W. Bates' "The Naturalist on the amazons" which was first published in 1863, describes his 11-year sojourn in Brazil. Later, in his book "As Birds of the Brazilian Forests", he wrote about the similar experience. 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 be a specialist feeder, taking only palm nuts, but also small amounts of other seeds, fruits and other matter. The diet of this species was likely influenced by the clearing of forests for farming and cattle-ranching by early colonists, as well the yatay (Butia) palms from which it got a large portion more info of its nutrition.
In the wild the Glaucous Macaw was often found in subtropical forests that had mountains and savannahs that were surrounded by palm trees, where it nested in tree cavities and on rocky banks, or in the palm fronds' top. The female incubates and then lays two eggs per.
The young Glaucous Macaws are altricial, which means they depend on their parents to take care of them until they become fully grown and fly. Both males and females are extremely committed to their offspring and will continuously hunt for food and shield them from predators.
Unfortunately unfortunately, the Glaucous macaw is no longer found in its former habitat. The disappearance of this magnificent bird is most likely due to the continued trapping for the pet trade and disturbance of habitat, especially the mass clearing of yatay palms from which it could have gotten its primary food source. The Glaucous macaw is listed under Critically Endangered.
Breeding
Glaucous macaws usually form long-term monogamous pairs with both parents taking an active role in the raising of the young. They breed in the dry season when food availability is at its greatest. The female will lay two to three eggs that are incubated by the mother for approximately 28 days. Once the chicks hatch they are fed by their parents via regurgitation for the first few weeks of their life. The young macaws begin to explore and learn to feed themselves. They also learn how to fly and forage.
The glaucous Macaw is extremely social bird. They are active during daylight hours, and rest during the night. During the night they usually seek refuge inside tree cavities or other nesting areas that are suitable. Their calls can be heard in the forest throughout the day.
While it is believed that the species will be able to recover from its decline in the wild, the bird faces many threats, including loss of habitat illegal trapping for the pet trade, and deforestation. It is believed that there are just 20 glaucous macaws 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 the blue-throated hummingbird. It can be distinguished by its vibrant blue feathers. The parrot is 70 centimeters in length and has a a powerful beak capable of breaking open nuts and seeds. This gorgeous bird is native to South America, and it can be found in many habitats such as forests, dry lowland grasslands, and wetland.
This majestic bird is a sign of South American biodiversity. It has a regal look with its slim body, bright blue feathers and its light build. The black and curly beak makes it easier to crack open nuts and seeds, which comprise a significant portion of its diet. It's a stunning bird, and is often used in bird shows. It is also popular in captivity where it can live for a lifetime.
