Glaucous Macaw
The glaucous Macaw is one of the rarest birds on earth. It is Critically Endangered and could become extinct in the wild.
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 be in the southwest region of Paraguay close to the city of Corrientes. The bird was male.
Origin
The Glaucous macaw is an endangered parrot species native to South America. This majestic bird is distinguished by a blue feather pattern, and a powerful beak that can break open seeds and nuts. Glaucous macaws form long-term monogamous families and both parents are involved in the raising of the chicks. The chicks are fed a diet of regurgitated food for the first couple of weeks of their lives, and then solid foods as the chicks develop. Parents play a crucial role in teaching young macaws to fly and hunt.
The glaucous Macaw has gone extinct, but rumors about its existence continue to spread across the globe. It is believed that the glaucous Macaw was extinct in the 1800s due to logging and cattle grazing of yatay palm (Butia yatay) trees, where these birds primarily gathered their meals. The Glaucous Macaw is believed have returned, and is usually kept with its larger relative, Lear’s macaw.
The glaucous Macaw can be found in sub-tropical rainforests in South America. They are most often located in areas with a lot of palm trees, and are thought to be extremely adaptable to various types of forested habitats. These beautiful birds are territorial and will protect the nesting and feeding areas from intruders.
There have been a number of reports involving the glaucous macaw through the years, but they are considered to be not reliable. The most recent claim of a wild occurrence involves a avicultural acquaintance of Ridgely's who claimed to have observed four Glaucous macaws in Califomia. This claim is untrue until it is substantiated by solid evidence. Many experts have concluded that the bird is likely to be extinct since 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 will be extremely uncommon to observe large numbers.
Habitat
The glaucous Macaw is an impressive bird, well-known for its size and turquoise-blue coloration. Its long tail and wings highlight its graceful and agile moves. This bird is a symbol of loyalty and love. Its beak, which is mostly black, is distinctive in its shape that allows it to crack nuts and seeds. They are a significant part of its diet.
The Glaucous Macaw is considered Critically Endangered by the IUCN, which notes that it is a small population and is at a significant risk of extinction. The species was previously relatively widespread, but it is found in northern Argentina and southern Paraguay, north-eastern Uruguay and Brazil from Parana state southwards where it nestted in cliffs along major rivers.
The Glaucous Macaw was not rare in its relatively small range, despite the fact that there were no reliable sightings since 1830. There were specimens collected until 1860 (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 savanna habitat which is surrounded by palm "islands", and riparian forest bands along river systems. It was a specialised food source for palm fruits, especially those of the chatay or yatay palm (Butia yatay), but it was also likely to feed on ripe and unripe fruit such as berries, nuts, and vegetables. It nests on steep slopes on cliffs, in cliffs, and occasionally in tree cavities.
This bird was likely gregarious and social, like other parrots. It was said that it could live to 14.4 years in captivity and was a reliable breeder that reproduced year after. The lifespan of the species in the wild was perhaps 50-80 years. This species was a potent seed disperser and could have contributed to the success of the yatay palm in its native habitats.
Feeding
The Glaucous Macaw (Anodorhynchus glaucus) is one of the most stunning of the parrot species and its presence has a powerful impact in its surroundings. This massive South American parrot is known for its bright blue feathers, bright yellow eyes and the teardrop-shaped lappet on the lower portion of its beak.
In the past, little was known of the feeding habits and diet of the Glaucous macaw. The earliest detailed references I have found are in two works by H.W. Bates' "The Naturalist on the amazons" which was first published in 1863, which describes his 11-year journey in Brazil. Later in his book "As Birds of the Brazilian Forests" He wrote about the similar experience. Both of them are about the Hyacinthine Macaw, Anodorhynchus Aureolarius. I have no reason to think that they could not apply to this species.
The website Glaucous macaw is believed to be a specialized feeder, consuming mainly palm nuts, but also tiny amounts of other fruits, seeds and vegetable matter. The diet of this species is likely to be influenced by the clearance of forests by the early colonists to cultivate and cattle ranching, as well as the removal of the yatay palm (Butia yatay) from which it could have received much of its food.
In the wild the Glaucous Macaw was often found in subtropical forests with mountains and savannahs that were surrounded by palm trees, where it nestled in tree cavities, on rocky banks or the top of palm fronds. Females incubate and lay two eggs on average.
The young Glaucous Macaws rely on their parents for care until they fly and fully grown. Both the males and females are very dedicated to their offspring, and hunt for food and defend them against predators.
Unfortunately unfortunately, the Glaucous Macaw has been extirpated from most of its former range. The disappearance of the magnificent bird is likely due to continued trapping for the pet industry as well as habitat disruption, especially the massive removal of palm yatays, which could have been their primary food source. The Glaucous macaw is classified as Critically Endangered.
Breeding
Glaucous macaws are typically monogamous couples and both parents play a role in raising the young. They breed during the dry season, 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. In the initial few weeks after hatching, the chicks are fed daily by their parents via regurgitation. The young macaws then begin to explore their surroundings and learn to feed themselves. They also learn to fly and hunt for food.
The glaucous Macaw can be described as a highly social bird. They are active during daylight hours and rest during the night. In the evening, they will often seek shelter inside tree cavities or other suitable nesting places. Their calls can be heard in the forest throughout the day.
Although it is hoped the species will recover from its decline in the wild, the bird is facing numerous threats, such as the loss of habitat, illegal trapping for the pet trade, and deforestation. Only about 20 glaucous Macaws are believed to be in the wild. The IUCN classifies the bird as "Critically Endangered--Possibly Extinct."
The glaucous macaw is also called the Lear's macaw, or the blue-throated hummingbird. It can be distinguished by its bright blue feathers. The parrot measures 70 centimeters long and has an impressive beak that is capable of slicing open nuts and seeds. This beautiful bird is native to South America, and it can be found in many habitats such as forests, dry lowland grasslands, and wetland.
This magnificent bird is a symbol of South American biodiversity. Its elegant appearance with its slim body, light build and bright blue feathers. The beak is curved and black, which aids it break open the seeds and nuts that make up a major portion of its diet. It is a beautiful bird, and is frequently featured in birds shows. It is also a favourite in the wild, where it can live for a lifetime.
