10 Wrong Answers To Common Glaucous Macaw Questions: Do You Know The Correct Ones?
Glaucous MacawThe glaucous Macaw is one of the rarest birds in the world. It is considered Critically Endangered and could be extinct in the wild.
Various aviculturalists have reported sightings of this bird However, the most recent sighting was 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 a bird native to South America. It is threatened. This magnificent bird is characterized by blue feathers, and a powerful beak capable of cracking open nuts and seeds. Glaucous Macaws live in monogamous couples and both parents care for the chicks. The chicks are fed regurgitated food in the first few weeks of their lives before being fed solid food as they grow. Parents are also responsible for teaching the young macaws to fly and hunt.
The glaucous Macaw is extinct, yet rumors of its existence persist all over the world. It is believed that the glaucous Macaw was extinct in the 1800s due to cattle grazing and logging in yatay palm (Butia yatay) trees, where these birds primarily gathered their meals. It is believed that the glaucous macaw made a comeback in captivity and is usually raised alongside its larger relative Lear's macaw.
The glaucous Macaw is found in sub-tropical rainforests of South America. They are most often found in areas with abundant palm trees, and are believed to be extremely adaptable to various types of forested habitats. These beautiful birds are also known to be extremely territorial and will protect their feeding and nesting areas from intruders.
Over the years there have been a variety of reports about the glaucous Macaw however they are generally not considered reliable. The most recent wild claim was made by an avicultural acquaintance of Ridgely who claimed to have spotted four Glaucous Macaws in Califomia. This is a ridiculous claim until it is substantiated by solid evidence. Many experts have concluded that the bird is likely to be extinct since there are no evidence of it in the last century. However they have always been willing to accept a slim chance of its survival. If it does survive it will be very rare to see large numbers.
Habitat
The Glaucous Macaw is a stunning bird, known for its large size and turquoise-blue coloring. The tail feathers and wings are long, which enhances its graceful and agile movement. The bird is an emblem of love and loyalty. Its beak, which is primarily black, has a distinctive shape that allows it crack seeds and nuts. They are a significant part 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 high risk of extinction. The 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 is nestled in cliffs alongside major rivers.
The Glaucous Macaw was not rare in its relatively small range, even though there were no reliable sightings since 1830. There were specimens collected until 1850 (in Corrientes). The last known living Glaucous Macaw was exhibited at the Buenos Aires Zoo in 1936 and is believed to have come from macaw for sale Brazil.
A reassessment of the historical documents suggests that this species was more generalist in its preferences for habitat with a preference for the savanna ecosystem, which was interspersed with palm "islands" and areas of riparian forest along river systems. It was a specific feeder of palm fruits, especially those of the yatay or chatay palm (Butia yatay), but it was also likely to consume ripe and unripe fruits such as berries, nuts, and vegetables. It nestled on slopes and cliffs, sometimes in tree cavities and laid an average clutch of two eggs.
Like all parrots, this bird was social and probably gregarious. It was reported that it could live up to 14.4 years in captivity, and was a reliable breeder that reproduced year after. In the wild, its lifespan was likely to be between 50 and 80 years. This species was a formidable seed disperser, and could have contributed to the success of the yatay palm in its native habitats.
Feeding
The Glaucous Macaw (Anodorhynchus glaucus) is among the most magnificent of all the parrot species and its presence has a powerful impact in its surroundings. This large South American bird is known for its vibrant blue feathers and yellow eyes, and also for its distinctive teardrop-shaped lappet that brackets the lower portion of its beak.
In the past, little was known about the diet of the Glaucous Macaw. The first detailed references I have found are two works by H.W. Bates, "The Naturalist on the Amazons" first published in 1863 about his 11 year sojourn in Brazil and later in his work "As Birds of the Brazilian Forests". Both are about the Hyacinthine Macaw, Anodorhynchus Aureolarius. I have no reason to think that they could not apply to this species.
The Glaucous macaw is believed to be a specialist eater, consuming only palm nuts, but also small amounts of other seeds, fruits and vegetable matter. The diet of this species was likely influenced by the clearing of forests for agriculture and cattle-ranching by early colonists as well as the removal of yatay (Butia) palms from which it got a large portion of its nutritional value.
In the wild, it was common to find the Glaucous macaw in subtropical forests and savannahs where palm trees were found. It nestled in tree cavities or on rocky banks and palm fronds. The female incubates and lays two eggs on average.
The young Glaucous Macaws rely on their parents for their care until they can fly and fully grown. Both females and males are extremely committed to their young and will tirelessly hunt for food and protect them from predators.
Unfortunately, the Glaucous macaw isn't found in most of its former habitat. The disappearance of the majestic bird is likely to be due to continued trapping for the pet industry and disturbance to habitat, particularly the massive removal of palm yatays, which may have been its main food source. The Glaucous Macaw is listed as Critically Endangered.
Breeding
Glaucous macaws are typically monogamous couples, with both parents playing part in raising the young. They breed during the dry season when the availability of food is at its greatest. The female lays two to three eggs that are incubated by the mother for about 28 days. For the first few weeks following hatching, the chicks are fed by their parents via regurgitation. The young macaws begin to explore and learn to feed themselves. They also learn how to fly and forage.
Like all birds, glaucous macaws are social animals. They are active during daylight hours, and rest during the night. In the evening they often seek refuge in tree cavities or other suitable nesting places. They are highly vocal, and their calls can be heard throughout the forest during the day.
While it is believed that the species will recover from its decline in the wild, the bird faces numerous threats, such as the loss of habitat, illegal trapping for the pet trade and deforestation. There are only about 20 glaucous Macaws that are estimated to be living in the wild. The IUCN classifies the bird as "Critically Endangered - possibly Extinct."
The glaucous Macaw is known as the Lear's macaw or blue-throated hummingbird, and is distinguished by its vivid blue feathers. The parrot measures 70 centimeters in length and has a powerful beaks that are capable of slicing open seeds and nuts. This gorgeous bird is native to South America, and it can be found in many habitats such as forests, dry lowland grasslands, and wetlands.
This majestic bird is a sign of South American biodiversity. Its appearance is elegant with its slim body, vibrant blue feathers and its light build. The black and curly beak helps it crack open seeds and nuts which are a large part of its diet. It is a stunning bird that is often seen in bird shows. It is also popular in captivity, where it can live for a long time.
