Glaucous Macaw
The glaucous macaw is considered to be one of the world's rarest birds. It is in serious danger and could be extinct.
The bird has been reported by aviculturists from 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 a threatened parrot species that is native to South America. This magnificent bird features a unique blue feather pattern and strong beak that is capable of breaking open tough nuts and seeds. Glaucous Macaws live in monogamous pairs and both parents care for the chicks. They feed their chicks regurgitated food for the first few weeks after birth, and then they begin to eat solid foods as they grow. Parents are also responsible for teaching young macaws to fly and hunt.
The glaucous macaw is believed to be extinct in the wild, yet stories of this gorgeous bird's existence persist throughout 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 would gather their food. It is currently believed that the glaucous Macaw has returned to captivity, where it is often kept alongside its larger cousin Lear's macaw.
In terms of habitat The glaucous macaw is able to be found in sub-tropical forests of South America. They are typically located in areas with a lot of palm trees, and they are thought to be extremely adaptable to different types of forested habitats. These beautiful birds are known to be very territorial and will protect their feeding and nesting areas from trespassers.
There have been a number of reports on the glaucous macaw through the years, but they are considered to be not reliable. The most recent report of a wild event is an friend of Ridgely's who claimed to have seen four Glaucous macaws in Califomia. This claim is untrue until it is supported with evidence. The absence of any reliable evidence of this bird in the last century has led many experts to think that it's likely extinct, but they have always been open to a remote possibility of its existence (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it is able to survive it will be extremely rare to see large numbers.
Habitat
The Glaucous Macaw is a stunning bird, well-known for its huge size and turquoise-blue coloration. The long tail and wings accentuate its graceful and agile movements. This bird is a symbol of loyalty and love. Its beak, which is primarily black, has a distinctive shape that allows it to crack seeds and nuts. They are a significant portion of its diet.
IUCN has classified the Glaucous Macaw as Critically Endangered. It says that there is a very small population of the bird and it is in high-risk of extinction. This species was once widespread however, it is now found in northern Argentina south Paraguay and north-eastern Uruguay and Brazil, from Parana state to south, where it is nestled in cliffs alongside major rivers.
Although there haven't been any credible sightings of the species since 1830, the Glaucous Macaw seemed not to be a rare species in its comparatively small range; specimens were captured from 1830 to 1850 (in Corrientes). The last known living Glaucous Macaw was displayed at the Buenos Aires Zoo in 1936 and is believed to have come from Brazil.
A re-examination 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 river systems. It was a particular in the consuming of palm fruit especially those of the yatay (or chatay) palm (Butia). However, it also ate ripe and unripe fruits and berries, nuts, and vegetable matter. It nestled on slopes and cliffs, sometimes in tree cavities and laid an average clutch of two eggs.
Like all parrots, this bird was social and likely to be gregarious. It could live for up to 14.8 years in captivity and was said to be a reliable breeder that reproduced year after year. In the wild, its lifespan was probably between 50 and 80 years. This species was a powerful seed disperser and could have contributed to the success of the yatay palm in its natural habitats.
Feeding
The Glaucous Macaw (Anodorhynchus glaucus) is among the most beautiful of the parrot species and its presence has an enormous impact on its environment. This large South American bird is known for its vivid blue feathers and yellow eyes as well as the distinctive teardrop-shaped lipped sleeve that covers the lower part of its beak.
In the past, little was known about feeding habits of the Glaucous Macaw. The earliest references to this subject that I have located are two works 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. I have no reason to believe that they don't apply to this species.
It is likely that the Glaucous Macaw was a specialized feeder of palm nuts and also took other seeds, fruits, and vegetable matter in small amounts. The diet of this species is likely to be affected by the clearing of forests by the early colonists to cultivate and cattle ranching, as well as the felling of the yatay palm (Butia yatay) from which it could have gotten its majority of its diet.
In the wild the Glaucous Macaw was commonly found in subtropical forests containing cliffs and savannahs with palm trees, where it nestled great green macaw in tree cavities, on rocky banks or the top of palm fronds. On average, a clutch of two eggs was laid and then incubated by the female.
The young Glaucous Macaws rely on their parents for their care until they can fly and are fully grown. 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 extirpated from the majority of its former range. The disappearance of this majestic bird is most likely due to the ongoing trapping for the pet trade as well as habitat disturbance, particularly the mass removal of yatay palms which it may have obtained its primary food source. The Glaucous macaw is classified as Critically Endangered.
Breeding
Glaucous Macaws form monogamous long-term pairs. Both parents are involved in raising their young. They breed during the dry season, when the availability of food is at its highest. Females lay an egg clutch that ranges from two to three eggs, which are incubated for a period of around 28 days. After hatching they are fed by their parents via regurgitation for the first few weeks of life. The young macaws begin exploring and learning to feed themselves. They also learn to fly and hunt for food.
Like all species of birds, glaucous macaws are highly social creatures. They are active during daylight hours, and rest at night. In the evening, they will often seek shelter inside tree cavities or other nesting spots that are suitable. Their calls can be heard in the forest throughout the day.
The species is expected to recover from its decline, however it is in danger of being wiped out by habitat loss illegal trapping of the bird for pet trade, and deforestation. Only about 20 glaucous Macaws are estimated to be living in the wild. The IUCN has classified 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 bright blue feathers. The parrot measures 70 centimeters in length and has a powerful beaks that are capable of cracking open seeds and nuts. This gorgeous bird is native to South America, and it is found in a variety of habitats, including grasslands, forests, dry lowland 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. Its beak is curvaceous and black, which aids it crack open the seeds and nuts that comprise a large portion of its diet. It's a beautiful bird, and it is often seen in bird shows. It is also a favourite in the wild, where it can be kept for a lifetime.
