Glaucous Macaw
The glaucous Macaw is one of the world's rarest birds. It is in danger of disappearing and could even be extinct.
A variety of aviculturalists have reported sightings of this bird, but the most recent was in 1992. The reported sighting was in the southwest of 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 features a distinctive blue feather pattern and a powerful beak capable of breaking open tough nuts and seeds. Glaucous macaws form long-term monogamous couples and both parents assist in raising the chicks. They feed their chicks regurgitated food for the first couple of weeks after birth, before they begin to eat 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 continue to circulate across the globe. It is estimated that the glaucous Macaw was extinct in the 1800s because of the logging industry and cattle grazing in yatay palm (Butia yatay) groves, where these birds typically gathered their food. The Glaucous Macaw is believed be making a comeback and is often kept along with its larger mate, Lear's macaw.
The glaucous Macaw lives in sub-tropical rainforests in South America. They are most often located in areas with a lot of palm trees, and are believed to be extremely adaptable to a variety of forested habitats. These beautiful birds are known to be extremely territorial and will defend their nesting and feeding areas from trespassers.
There have been a variety of reports about the glaucous macaw over the years, but many are considered to be unreliable. 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 unacceptable until it is supported with hard evidence. Many experts have concluded that the bird is likely extinct as there are no records in the last century. However they have always been willing to accept a small chance of its survival. If it survives, it is extremely unlikely to reach large numbers.
Habitat
The glaucous macaw is a striking bird, renowned for its huge size and dazzling turquoise-blue coloration. The long tail and wings accentuate its graceful and agile movements. It is also a symbol of loyalty and love. Its beak, which is predominantly black, has a distinct shape that allows it to break seeds and nuts. They are a significant portion of its diet.
The Glaucous Macaw is considered Critically Endangered by the IUCN, which notes that it has an extremely small population and is at high risk of extinction. The species was once widespread but is now found in northern Argentina, south Paraguay and north-eastern Uruguay, as well as Brazil and Brazil from Parana state to south, where it is nestled in cliffs that run alongside major rivers.
The Glaucous Macaw was not rare in its relatively small range, even though there were no reliable sightings after 1830. The specimens were collected up until the year 1860 (in Corrientes). The last known living Glaucous Macaw was displayed at the Buenos Aires Zoo in 1936 and is believed to be from Brazil.
The reassessment suggests that the species is a generalist, preferring the savanna habitat, which is which is surrounded by palm "islands", and bands of riparian forests along river systems. It was a specific feeder of palm fruits, especially those of the chatay palm (Butia yatay), but it was also likely to feed on ripe and unripe fruits as well as berries, nuts and vegetables. It nestled on slopes and in cliffs occasionally in tree cavities and laid an average clutch of two eggs.
This bird was likely to be gregarious and social, similar to other parrots. It was able to live up to 14.8 years in captivity. It was said to be a dependable breeder that reproduced year after year. In the wild, its life expectancy was likely to be between 50 and 80 years. This species was a powerful disperser of seeds and may have contributed to the success of the palm yatay species in its natural habitat.
Feeding
The Glaucous Macaw is one of the most stunning parrots. The presence of this parrot has an impact on the environment. This massive South American bird is known for its vivid blue feathers and yellow eyes as well as its distinctive teardrop-shaped lappet that brackets the lower part of its beak.
Up until recently, very little was known of the feeding habits and diet of the Glaucous macaw. The first references to the subject I have found are in two works by H.W. Bates, "The Naturalist on the Amazons" first published in 1863, detailing his 11 year sojourn in Brazil and later in his book "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 specialist for the consumption of palm nuts. It also ate other seeds, fruits, and vegetable matter in smaller amounts. The diet of this species is likely to have been influenced by the clearance of forests by early colonists to cultivate and cattle ranching as well as the destruction of the yatay palm (Butia yatay) from which it may have gotten its majority of its nutrition.
In the wild the Glaucous Macaw was found in subtropical forests with cliffs and savannahs with palm trees, where it nestled in tree cavities, on rocky banks or the top of palm fronds. Females incubate and lay two eggs per.
The young Glaucous Macaws rely on their parents for their care until they fly and fully grown. Both males and females are extremely committed to their offspring and will tirelessly hunt for food and defend them from predators.
Unfortunately unfortunately, the Glaucous Macaw has been extirpated from the majority of its previous range. The disappearance of this magnificent bird is probably due to the continued trapping of pets for the pet trade, as well as disturbance to habitat, specifically the wholesale removal of yatay palms which it may have obtained its primary food source. The Glaucous Macaw is listed as Critically Endangered.
Breeding
Glaucous Macaws are monogamous, long-term pair. Both parents are involved in raising their young. They breed during the dry season, which is when the food supply is at its macaw cage highest. Females lay two to three eggs which are incubated by the mother for around 28 days. Once the chicks hatch they are fed by their parents via regurgitation for the first few weeks of life. The macaws' young begin to explore their surroundings and begin to learn to feed themselves. They also learn to fly and forage.
The glaucous Macaw can be described as a extremely social bird. They are active during daylight hours, and rest at night. At night they usually seek shelter inside tree cavities or other nesting spots that are suitable. Their calls can be heard throughout the forest throughout the day.
The species is expected to rebound from its decline, however it is facing numerous threats, including habitat loss and illegal trapping of the bird for pet trade, and deforestation. There are only about 20 glaucous Macaws that are estimated to be living in the wild. The IUCN classifies the bird as "Critically Endangered - possibly Extinct."
The glaucous Macaw is called the Lear's macaw or the blue-throated hummingbird, and is distinguished by its vibrant blue feathers. It is a large parrot, measuring 70 centimeters in length and has a sturdy beak that can break open tough nuts and seeds. This gorgeous bird is native to South America and can be found in various habitats such as forests, lowland grasslands and wetlands.
This majestic bird is an emblem of South American biodiversity. Its appearance is elegant, with its slender build, lightweight body and vivid blue feathers. Its beak is curved and black, which helps it open the nuts and seeds that make up a major portion of its diet. It is a stunning bird and is often used in birds shows. It is also popular in captivity, where it can live a lifetime.
