Glaucous Macaw
The glaucous macaw is considered to be one of the rarest birds on earth. It is critically endangered and could even be extinct.
The bird has been observed by aviculturists across the globe however the most recent sighting was recorded in 1992. The alleged sighting was reported to have occurred in the southwestern region of Paraguay, near the city of Corrientes. The bird was male.
Origin
The Glaucous macaw is an endangered parrot species that is native South America. This magnificent bird is distinguished by a blue feather pattern, and a powerful beak that can break open seeds and nuts. Glaucous Macaws form monogamous long-term pairs and both parents care for the chicks. They feed the chicks a diet of regurgitated food for the first few weeks after birth, and later they begin to eat solid foods as they grow. Parents also play a crucial role in teaching young macaws to fly and hunt.
The glaucous Macaw is thought to be extinct in the wild, but reports of this beautiful bird's existence persist throughout the world. The glaucous Macaw is believed to have been extinct in the 1800s due to the logging industry and cattle grazing in yatay (Butia) palm groves from which the birds would gather their food. The glaucous Macaw is believed to have returned, and is often kept along with its larger mate, Lear's macaw.
The glaucous Macaw is found in sub-tropical rainforests in South America. They are typically found in areas that have plenty of palm trees, and are thought to be extremely adaptable to different types of forested habitats. Leia blue macaw and red macaw are recognized as being very territorial and will defend their nesting and feeding areas from intruders.
There have been a lot of reports about the glaucous macaw throughout the years, but most are considered to be unreliable. The most recent claim of a wild event is an friend of Ridgely's who claimed to have observed four Glaucous macaws in Califomia. This is completely untrue until it can be verified by hard evidence. Many experts have concluded that the bird is likely extinct because there are no records in the last century. However they have been willing to accept a small chance of its survival. If it survives, it is extremely unlikely to be seen in large numbers.
Habitat
The glaucous Macaw is an impressive bird, known for its large size and turquoise-blue coloring. The tail feathers and wings are long, enhancing its graceful and agile movement. This bird is a symbol of love and loyalty. Its beak, which is predominantly black, is distinctive in its shape that allows it to crack seeds and nuts. They are a significant part its diet.
The Glaucous Macaw is considered Critically Endangered by the IUCN and the IUCN states that it is a small population and is at a significant chance of becoming extinct. This species was once widespread but is now found in northern Argentina and south Paraguay and north-eastern Uruguay as well as Brazil from Parana state to the south, where it nests in cliffs alongside major rivers.
The Glaucous Macaw was not rare in its small area, despite the fact that there was no proof of sightings since 1830. The specimens were collected until 1850 (in Corrientes). The last living Glaucous Macaw believed to originate from Brazil, was exhibited in the Buenos Aires Zoo back in 1936.
Reassessment suggests that this species is a generalist and prefers the savanna habitat, which is which is surrounded by palm "islands", and riparian forests along river systems. It was a specific eater of palm fruits, particularly those of the yatay or chatay palm (Butia yatay) however, it was also likely to consume unripe and ripe fruit as well as berries, nuts and vegetables. It nestled on slopes and in cliffs, sometimes in tree cavities and laid an average clutch of two eggs.
This bird was likely gregarious and social, similar to other parrots. It was believed 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 likely to be between 50 and 80 years. This species was a powerful disperser of seeds, and could have contributed to the success of the 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 has a powerful impact in its environment. This massive South American bird is known for its vivid blue feathers and yellow eyes, as well as its distinctive teardrop-shaped lappet which adorns the lower portion of its beak.
As of the time of writing, little was known about the eating habits and diet of the Glaucous macaw. The first detailed references I have found are two works by H.W. Bates' "The Naturalist on Amazons" first published in 1863, and describes his 11-year sojourn in Brazil. Later in his book "As Birds of the Brazilian Forests" He wrote about the same experience. Both of these references to the Hyacinthine Macaw (Anodorhynchus aureolarius) however I see no reason to think that they're not applicable 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 smaller amounts. This species' diet 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 derived a lot of its nutritional value.
In the wild it was commonplace to see the Glaucous macaw in savannahs and subtropical forests where palm trees were found. It hid in tree cavities, or on rocky banks and palm fronds. On average two eggs were laid in a clutch. 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 become fully full fledged. Both the males and females are very committed to their offspring and hunt for food and protect them against predators.
Unfortunately the Glaucous Macaw has been extirpated from its entire previous range. The disappearance of this magnificent bird is likely due to the continued trapping of birds for the pet industry, as well as disturbance to habitat, particularly the massive clearing of palm yatays which may have been its primary food source. The Glaucous Macaw is listed as Critically Endangered.
Breeding
Glaucous Macaws form monogamous pair. Both parents are involved in raising their young. They breed during the dry season, which is when the food supply is at its highest. Females lay an egg clutch that ranges from two to three eggs that are incubated for a period of around 28 days. Once the chicks hatch, they are fed by their parents via regurgitation for the first couple of weeks of their lives. Then the young macaws begin to explore their surroundings and learn to eat themselves. They also learn to fly and forage.
The glaucous Macaw is a extremely social bird. They are active during daylight hours and rest at night. They often seek refuge in cavities in trees or other suitable nesting places for the night. Their calls can be heard in the forest throughout the day.
The species is expected to rebound from the decline, but it is facing numerous threats, including habitat loss and illegal trapping of the bird to sell on the pet market and deforestation. It is estimated 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 is called the Lear's macaw or blue-throated hummingbird, and is distinguished by its vibrant blue feathers. It is a large parrot measuring 70 centimeters long, and has a strong beak that can crack open tough nuts and seeds. This gorgeous bird is native to South America and can be found in various habitats such as grasslands, lowland forests and wetlands.
This majestic bird is a symbol of South American biodiversity. Its elegant appearance with its slim body, light weight and bright blue feathers. Its beak is curved and black, which helps it open the seeds and nuts that comprise a large portion of its diet. It is a stunning bird, and is frequently featured in birds shows. It is also a favorite in the wild, where it can be kept for a lifetime.
