Glaucous Macaw
The glaucous Macaw is among 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, but the most recent was 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 has a distinctive blue feather pattern as well as a strong beak that is capable of breaking open hard nuts and seeds. Glaucous Macaws are monogamous pairs, and both parents raise the chicks. The chicks are fed regurgitated food for the first couple of weeks of life and then a variety of solid foods as the chicks develop. Parents are also responsible for teaching young macaws to fly and hunt.
The glaucous macaw is believed to be extinct in the wild, yet reports of this beautiful bird's existence persist all over the world. The glaucous Macaw is believed to be extinct by the 1800s because of logging and cattle grazing on yatay (Butia) palm groves where the birds would gather their food. The glaucous Macaw is believed to be making a comeback and is often kept with its larger relative, Lear’s macaw.
In terms of habitat The glaucous macaw is able to be found in sub-tropical forests of South America. They are most often found in areas with numerous palm trees. They are also known to be extremely adaptable to different types of forest habitats. These beautiful birds are also known to be extremely territorial and will protect their nesting and feeding areas from intruders.
In the past, there have been many reports on the glaucous Macaw, but they are generally considered unreliable. The most recent report of a wild event is an avicultural acquaintance of Ridgely's who claimed to have seen four Glaucous macaws in Califomia. This claim is completely unacceptable until it is verified by hard evidence. The absence of any credible records of this bird in the last century has caused many experts to believe that it is extinct, however they have always been willing to accept the possibility of existence (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it survives it will be extremely rare to see large numbers.
Habitat
The Glaucous Macaw is a stunning bird, renowned for its size and turquoise-blue coloring. Its long tail and wings accentuate its graceful and agile movement. This bird is a symbol of loyalty and love. Its beak, which is primarily black, has a distinct shape and allows it to break seeds and nuts. These are a large 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 a significant chance of becoming extinct. The species was once widespread however, it is now found in northern Argentina, south Paraguay and north-eastern Uruguay as well as Brazil, from Parana state to south, where it resides in cliffs alongside major rivers.
Although there haven't been any reliable sightings of this species since 1830, the Glaucous Macaw seemed not to be a rare species in its limited range. specimens were captured up to 1860 (in Corrientes). The last known living Glaucous Macaw was seen at the Buenos Aires Zoo in 1936 and is believed to have come from Brazil.
The reassessment suggests that the species is a generalist, preferring savanna habitat that is interspersed with palm "islands", and riparian forests along rivers. It was a particular in the consuming of palm fruit especially those of the yatay (or chatay) palm (Butia). However, chestnut fronted macaw ate ripe and unripe fruits as well as berries, nuts and vegetable matter. It nestled on steep slopes and cliffs, occasionally in tree cavities and laid an average clutch of two eggs.
As with other parrots this bird was social and was probably gregarious. It could live up to 14.8 years in captivity. It was said to be a reliable breeder, reproducing year after year. The lifespan of the species in the wild was perhaps 50-80 years. This species was a powerful disperser of seeds and may be a factor in the success of the palm yatay in its natural habitats.
Feeding
The Glaucous Macaw is one of the most stunning parrots. Its presence can have an enormous influence on the surrounding. This huge South American parrot is known for its bright blue feathers, yellow eyes, and the teardrop-shaped lipped on the lower part its beak.
Up until recently, very little was known about the eating habits of the Glaucous Macaw. The earliest detailed references I have found are in 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 similar experience. Both of these refer to the Hyacinthine Macaw (Anodorhynchus aureolarius) However, I have no reason to believe that they are not applicable to this species.
macaw cage is likely be a specialist feeder, consuming mainly palm nuts however, there were also small amounts of other seeds, fruits and vegetable matter. This species' diet was likely influenced by the clearing of forests for farming and cattle-ranching by early colonists, and the removal of yatay (Butia) palms from which it derived a lot of its nutrition.
In the wild the Glaucous Macaw was commonly found in subtropical forests that had the savannahs and cliffs surrounded by palm trees, where it nestled in tree cavities and on rocky banks or the top of palm fronds. The female incubates and then lays two eggs on average.
The young Glaucous Macaws are altricial, meaning they depend on their parents to look after them until they're fully fledged and can fly. Both the males and females are very committed to their offspring and will hunt for food and defend them from predators.
Unfortunately unfortunately, the Glaucous macaw has been found in most of its former habitat. The disappearance of this majestic bird is probably due to the continuing trapping of pets for the pet trade and habitat disturbance, particularly the wholesale removal of yatay palms which it could have gotten its primary food source. The Glaucous Macaw is classified as Critically Endangered.
Breeding
Glaucous Macaws form monogamous pair. Both parents are involved in raising their young. They breed during the dry season, when the food supply is at its highest. The female lays two to three eggs which are incubated by the mother for about 28 days. Once the chicks hatch they are fed by their parents through regurgitation for the first couple of weeks of their life. The young macaws then begin to explore their surroundings and learn how to eat themselves. They are also taught how to fly and forage.
Like all species of birds, glaucous macaws are highly social creatures. They are active during daylight hours and rest at night. They will often seek shelter in tree cavities or other suitable nesting sites to sleep. They are extremely vocal and their calls can be heard throughout the forest during the day.
While it is hoped that the species will recover from its decline in the wild, the bird faces many threats, including loss of habitat and illegal trapping for pet trade and deforestation. There are only about 20 glaucous Macaws that are believed to be in the wild. The IUCN has classified the bird as "Critically endangered, possibly extinct."
The glaucous macaw, also known as Lear's Macaw, or the blue-throated Hummingbird, is distinguished by its vivid blue feathers. It is a large parrot, with a length of 70 centimeters and has a sturdy beak that is able to break open hard nuts and seeds. This beautiful bird is native to South America, and it is found in a variety of habitats such as grasslands, forests, dry lowland and wetland.
This magnificent bird is a symbol of South American biodiversity. It has a regal appearance, with its slender body, light build and bright blue feathers. Its black and curved beak allows it to break open nuts and seeds, which make up a significant part of its diet. It is a stunning bird that is often seen in birds shows. It is also popular in captivity where it can live a lifetime.
