Glaucous Macaw
The glaucous Macaw is one the rarest birds in the world. It is Critically Endangered and could become extinct in the wild.
The bird has been reported by aviculturists in various countries however the most recent sighting was recorded in 1992. The alleged sighting was reported to be in the southwest of Paraguay near the city Corrientes. The bird was a male.
Origin
The Glaucous macaw is a threatened parrot species that is native South America. This magnificent bird features a distinctive blue feather pattern and a powerful beak that is capable of breaking open tough seeds and nuts. Glaucous macaws are known to form long-term monogamous couples and both parents help raise the chicks. They feed their chicks regurgitated food for the first few weeks after birth, before they begin to eat solid foods as they grow. Parents are also responsible for teaching young macaws to fly and hunt.
The glaucous Macaw is thought to be extinct in the wild, yet rumors of this beautiful bird's existence continue to spread all over the world. It is believed 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 mostly ate their food. The glaucous Macaw is believed to be making a comeback and is usually kept with its larger cousin, Lear's macaw.
The glaucous Macaw is found in sub-tropical rainforests in South America. They are most often found in areas with abundant palm trees, and they are known to be highly adaptable to various types of forested habitats. These beautiful birds are also known to be extremely territorial and will defend their feeding and nesting areas from intruders.
There have been a number of reports about the glaucous macaw over the years, but they are considered to be unreliable. 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 is a ridiculous claim until it is substantiated with evidence. Many experts have concluded that the bird is likely extinct because there are no records from the last century. However, they have always been willing accept a remote chance of its survival. If it is able to survive, 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 long tail and wings highlight its graceful and agile moves. The bird is an emblem of love and loyalty. Its beak is mostly black, and it has a distinctive shape that allows it to crack open seeds and nuts which make up a large portion of its diet.
The Glaucous Macaw is considered Critically Endangered by the IUCN which states that it is a small population and is at high chance of becoming extinct. The species was once quite widespread, but today it is found only in northern Argentina, southern Paraguay, north-eastern Uruguay and Brazil from Parana state southwards where it was a nesting place in cliffs along major rivers.
While there have been no reliable sightings of this species since 1830, the Glaucous Macaw seemed not to be extremely rare within its relatively limited range; specimens were collected up to 1850 (in Corrientes). The last known living Glaucous Macaw was exhibited at the Buenos Aires Zoo in 1936 and is believed to be from Brazil.
A re-examination of the historical records suggests that this species was a rather generalist in its habitat preferences, with a preference for savanna habitat intermingled with palm "islands" and bands of riparian forest along rivers. It was a particular feeder of palm fruit especially those of the yatay (or chatay) palm (Butia). However, it also ate ripe and unripe fruits as well as berries, nuts and even vegetable matter. It nestled on slopes and in cliffs occasionally in tree cavities and laid an average clutch of two eggs.
This bird was likely gregarious and social, similar to other parrots. It could live up to 14.8 years in captivity. It was believed to be a dependable breeder, reproducing year after year. The life expectancy of this species in the wild was about 50 to 80 years. This species was a potent disperser of seeds and may be a factor in the success of the palm yatay species in its natural habitat.
Feeding
The Glaucous Macaw is one of the most stunning parrots. Its presence can have an enormous impact on the environment. This massive South American bird is known for its vibrant blue feathers and yellow eyes, as well as its distinctive teardrop-shaped lappet that brackets the lower portion of its beak.
Up until recently, very little was known of the eating habits and diet of the Glaucous macaw. The first detailed references I have discovered are in two books by H.W. Bates, "The Naturalist on the Amazons" first published in 1863 on his 11 year sojourn in Brazil and later in his work "As Birds of the Brazilian Forests". Both of them are about the Hyacinthine Macaw, Anodorhynchus Aureolarius. I have no reason to believe that they don't apply to this species.
The Glaucous macaw is believed to be a specialist eater, consuming only palm nuts as well as small amounts of other seeds, fruits and vegetable matter. The diet of this species is likely to be influenced by the clearance of forests by the early colonists for agriculture and cattle ranching and 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 that had the savannahs and cliffs surrounded by palm trees where it nested in tree cavities, on rocky banks, or in the palm fronds' top. The female incubates and then lays two eggs on average.
The young Glaucous Macaws are altricial, meaning they depend on their parents to care for them until they become fully grown and fly. Both the male and female are extremely dedicated to their offspring and constantly hunt for food and shield them from predators.
Unfortunately the Glaucous macaw isn't found in most of its former habitat. The disappearance of this magnificent bird is likely to be due to the continued trapping of birds for the pet industry as well as disturbance to habitat, particularly the mass clearing of palm yatays which may have been its primary food source. The Glaucous Macaw is classified as Critically Endangered.
Breeding
Glaucous macaws typically form long-term monogamous pairs, with both parents playing an active role in read more the raising of the young. They breed during the dry season, when the food supply is at its highest. The female lays two to three eggs that are incubated by the mother for about 28 days. After hatching they are fed by their parents through regurgitation for the first few weeks of their life. The young macaws then begin to explore their surroundings and learn how to feed themselves. They are also taught how to fly and hunt for food.
The glaucous Macaw is highly social bird. They are active during daylight hours and rest during the night. They will often seek shelter in tree cavities or other suitable nesting places to sleep. Their calls can be heard throughout the forest throughout the day.
The species is expected to recover from the decline, however it faces many threats including habitat loss, illegal trapping of the bird to sell on the pet market 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 Blue-throated Hummingbird, is distinguished by its vivid blue feathers. It is a large bird, with a length of 70 centimeters and features a robust beak that can crack open seeds and nuts that are tough to break. This beautiful bird is native South America and can be found in a variety of habitats such as grasslands, forests, and lowland wetlands.
This magnificent bird is a sign of South American biodiversity. Its appearance is elegant, with its slender build, lightweight body, and vibrant blue feathers. Its beak is curvaceous and black, which aids it crack open the seeds and nuts that comprise a large portion 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 for a lifetime.
