Glaucous Macaw
The glaucous Macaw is among the rarest birds in the world. It is Critically Endangered, and may be extinct in the wild.
This bird has been reported by aviculturists in various countries However, the most recent sighting was recorded in 1992. This alleged sighting was in the southwest region of Paraguay near the city Corrientes. The bird was male.
Origin
The Glaucous macaw is an endangered parrot species that is native South America. This magnificent bird has a distinctive blue feather pattern as well as a powerful beak that is capable of breaking open hard seeds and nuts. Glaucous macaws form long-term monogamous couples and both parents assist in raising the chicks. They feed the chicks regurgitated food for the first couple of weeks after birth, and then they begin to eat solid food 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 reports of this beautiful bird's existence continue to spread all over the world. It is estimated that the glaucous Macaw was extirpated in the 1800s due to cattle grazing and logging in yatay palm (Butia yatay) groves, where these birds mostly ate their food. It is believed that the glaucous macaw has returned to captivity in the wild, where it is raised alongside its larger relative Lear's macaw.
In terms of habitat the glaucous macaw can be found in subtropical forests of South America. They are usually found in areas with abundant palm trees, and are believed to be extremely adaptable to different types of forested habitats. These beautiful birds are territorial and will protect the feeding and nesting area from intruders.
Over the years there have been many reports about the glaucous Macaw, but they are generally regarded as unreliable. The most recent report of a wild occurrence involves an friend of Ridgely's who claimed to have observed four Glaucous macaws in Califomia. This is a ridiculous claim until it is supported by solid evidence. Many experts have concluded that this bird is likely extinct because there are no evidence of it in the last century. However, they have always been willing to accept a small chance of its survival. If it survives it is highly unlikely to reach large numbers.
Habitat
The macaw with the glaucous is a striking bird, renowned for its size and dazzling turquoise-blue coloration. Its long tail and wings accentuate its graceful and agile movement. It is also an emblem of affection and loyalty. Its beak is primarily black and has a distinctive shape that allows it to open nuts and seeds, which constitute a significant part of its diet.
IUCN has classified the Glaucous Macaw as Critically Endangered. It notes that there is a very small population of the bird, and that it is at a risk of extinction. This species was once widespread, but is now only found in northern Argentina, south Paraguay and north-eastern Uruguay as well as Brazil, from Parana state to the south, where it resides in cliffs along major rivers.
Although there have been no reliable sightings of this species since 1830, the Glaucous Macaw seemed not to be extremely rare within its comparatively small range; specimens were captured until 1860 (in Corrientes). The last living Glaucous Macaw believed to be from Brazil, was exhibited in the Buenos Aires Zoo back in 1936.
Re-evaluation of the historical documents suggests that this species was a more generalist in its habitat preferences, with a preference for areas of savanna that were interspersed with palm "islands" and bands of riparian forest along rivers. It was a particular food source for palm fruits, specifically those of the chatay or yatay palm (Butia yatay) however, it was likely to also feed on ripe and unripe fruit such as berries, nuts, and vegetables. It nestled on slopes and cliffs, sometimes in tree cavities, and laid an average clutch of two eggs.
This bird was likely to be gregarious and social, just like other parrots. It was said that it could live for up to 14.4 years in captivity, and was a reliable breeder who reproduced year after year. In the wild, its life expectancy was probably between 50 and 80 years. The species was a strong disperser of seeds, and could be a factor in the success of the palm yatay species in its natural habitats.
Feeding
The Glaucous Macaw (Anodorhynchus glaucus) is among the most beautiful of the species of parrots and has a an immense impact in its environment. This huge South American parrot is known for its bright blue feathers, bright yellow eyes and the teardrop-shaped lappet on the lower part its beak.
Until recently very little was known about the eating habits 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 on his 11 year sojourn in Brazil and later in his book "As Birds of the Brazilian Forests". Both are about the Hyacinthine Macaw, Anodorhynchus Aureolarius. I have no reason to believe that they don't apply to this species.
It is probable that the Glaucous Macaw was a particular feeder of palm nuts and also ate other seeds, fruits, and vegetable matter in small 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 removal of the yatay palm (Butia yatay) from which it could have gotten a lot of its nutrition.
In the wild, it was common to find the Glaucous macaw in savannahs and forests that were subtropical where palm trees were found. It was found in tree cavities or on rocky banks or palm fronds. The female incubates and lays two eggs on average.
The young Glaucous Macaws are altricial, which means they depend on their parents to look after them until they become fully fledged and can fly. Both males and females are committed to their offspring and will hunt for food and protect them against predators.
Unfortunately the Glaucous macaw is no longer found in its former habitat. The disappearance of the majestic bird is likely to be due to trapping that continues for the pet industry, as well as disturbance of habitat, specifically the mass removal of palm yatays, which could have been their primary food source. The Glaucous macaw is listed as Critically Endangered.
Breeding
Glaucous Macaws form monogamous couples. Both parents are involved in the raising of their young. They breed during the dry season when the availability of food is at its highest. The female will lay two to three eggs that are incubated by the mother for approximately 28 days. When the chicks are born they are fed by their parents through regurgitation for the first few weeks of life. Macaws are then able to explore and learn to feed themselves. They also learn how to fly and forage.
The glaucous Macaw is highly social bird. They are active during the day but are restful at night. They usually seek shelter in cavities in trees or other suitable nesting places to sleep. Their calls can be heard in the forest throughout the day.
While it is believed that the species will recover from its decline in the wild, the bird faces numerous threats, including the loss of habitat illegal trapping for the pet trade and deforestation. It is estimated that there are just 20 glaucous macaws 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. The parrot is 70 centimeters in length and has a powerful beaks that are capable of slicing open seeds and nuts. This beautiful bird is native to South America, and it is found in a variety of habitats like grasslands, forests, dry lowland, and wetlands.
This magnificent bird is a symbol of South American biodiversity. It has a regal appearance with its slim body, light weight and vivid Pixie mini macaw blue feathers. Its black and curved beak helps it crack open seeds and nuts, which are a large part of its diet. It is a beautiful bird and is often used in birds shows. It is also popular in captivity where it can live a lifetime.
