Glaucous Macaw
The glaucous Macaw is one the rarest birds in the world. It is considered Critically Endangered, and may be extinct in the wild.
Various birdwatchers have reported sightings this bird however the most recent sighting was in 1992. This alleged sighting was in the southwest region of Paraguay close to the city of Corrientes. The bird was a male.
Origin
The Glaucous macaw is a threatened parrot species that is native South America. This majestic bird is distinguished by a blue feather pattern, and a strong 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. They feed their chicks regurgitated food for the first few weeks after birth, before they begin to eat solid food as they grow. Parents are also responsible for teaching the young macaws to fly and hunt.
The glaucous macaw is considered to be extinct in the wild, yet stories of this gorgeous bird's existence persist all over the world. 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 primarily gathered their meals. It is believed that the glaucous macaw returned to captivity, where it is often raised alongside its larger relative, Lear's macaw.
The glaucous Macaw lives in sub-tropical rainforests in South America. They are typically located in areas where there are numerous palm trees. They are also known to be extremely adaptable to different types of forest environments. These beautiful birds are territorial and defend the nesting and feeding areas from intruders.
In the past, there have been a variety of reports of the glaucous macaw, but they are generally considered unreliable. The most recent claim of a wild occurrence involves a avicultural acquaintance of Ridgely's who claimed to have seen four Glaucous macaws in Califomia. This is a completely absurd claim until it is verified with hard evidence. The lack of any acceptable evidence of this bird in the past century has caused many experts to conclude that it is likely extinct, however they have always accepted a remote possibility of its survival (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it is able to survive it will be extremely uncommon to observe large numbers.
Habitat
The macaw with the glaucous is a striking bird that is known for its large size and stunning turquoise-blue coloration. The long tail and wings highlight its graceful and agile movements. This bird is a symbol of loyalty and love. Its beak, which is mostly black, has a distinct shape that allows it to break seeds and nuts. They are a significant part its diet.
IUCN has classified the Glaucous Macaw as Critically Endangered. It states that there is only a tiny population of this bird, and that it is at a risk of extinction. This species was formerly relatively widespread, but it is only found in northern Argentina as well as 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 area, even though there was no proof of sightings since 1830. The specimens were collected until 1860 (in Corrientes). The last known living Glaucous Macaw was exhibited at the Buenos Aires Zoo in 1936 and is believed to have come from Brazil.
Re-evaluation of the historical documents suggests that this species was a rather generalist in its habitat preferences, with a preference for the savanna ecosystem, which was interspersed with palm "islands" and forests of riparian along rivers. It was a specialised food source for palm fruits, specifically those of the chatay or yatay palm (Butia yatay) but it could also feed on ripe and unripe fruit as well as berries, nuts and vegetables. It nestled on steep slopes and cliffs, sometimes in tree cavities and laid an average clutch of two eggs.
Like all parrots, this bird was social and was likely to be sociable. 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 life expectancy was likely to be between 50 and 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 is one of the most beautiful parrots. Its presence has an enormous influence on the surrounding. This huge South American bird is known for its vivid blue feathers and eyes that are yellow, as well as the distinctive teardrop-shaped lipped sleeve that covers the lower part of its beak.
As of the time of writing, little was known of the food 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 Amazons" which was first published in 1863, describes his 11-year stay in Brazil. Later, in his book "As Birds of the Brazilian Forests", he wrote about the same experience. Both of these are about the Hyacinthine Macaw (Anodorhynchus aureolarius), but I have no reason to think that they're not applicable to this species.
The Glaucous macaw is likely to be a specialized feeder, taking only palm nuts however, there were also tiny amounts of other fruits, seeds and vegetable matter. This species' diet was likely influenced by the clearing of forests for agriculture and cattle-ranching by early colonists, as well the yatay (Butia) palms from which it received much 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 clutches of eggs was laid and then incubated by the female.
The young check here Glaucous Macaws are altricial, which means they depend on their parents to take care of them until they are fully fledged and can fly. Both the males and females are committed to their offspring and will hunt for food and protect them against predators.
Unfortunately, the Glaucous Macaw has been eliminated 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 removal of palm yatays, which may have been its primary food source. The Glaucous Macaw is listed as Critically Endangered.
Breeding
Glaucous macaws are typically monogamous pairs with both parents taking a role in raising the young. They breed in the dry season, when food is plentiful. The female lays an egg clutch of between two and three eggs that are incubated for about 28 days. In the initial few weeks after hatching, the chicks are fed by the parents via regurgitation. The young macaws then begin to explore and learn to feed themselves. They also learn to fly and forage.
The glaucous Macaw is highly social bird. They are active during the day and spend their nights resting. At night they often seek refuge 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 the decline, but it is in danger of being wiped out by habitat loss and illegal trapping of the bird for pet trade, and deforestation. There are only about 20 glaucous Macaws that are believed to exist in the wild. The IUCN has classified the bird as "Critically endangered, possibly extinct."
The glaucous Macaw is sometimes referred to as Lear's Macaw or Blue-throated Hummingbird, is distinguished by its vivid blue feathers. The parrot is 70 centimeters in length and has a an impressive beak that is capable of breaking open nuts and seeds. This gorgeous bird is native to South America, and it is found in a variety of habitats such as forests, dry lowland grasslands, and wetland.
This magnificent bird is a sign of South American biodiversity. Its appearance is elegant with its slim body, bright blue feathers, and a light build. The black and curly beak allows it to break open nuts and seeds, which make up a significant part of its diet. It's a stunning bird, and it is often seen in bird shows. It is also popular in captivity, where it can live for a long time.
