Glaucous Macaw
The glaucous Macaw is among the rarest birds in the world. It is Critically Endangered and could become extinct in the wild.
A variety of aviculturalists have reported sightings of this bird However, the most recent sighting was in 1992. This alleged sighting was in southwest Paraguay near the city Corrientes. The bird was a male.
Origin
The Glaucous Macaw is a species of parrot native to South America. It is threatened. This magnificent bird is distinguished by a blue feather pattern, and a powerful beak capable of cracking open seeds and nuts. Glaucous macaws are known to form long-term monogamous couples and both parents are involved in the raising of the chicks. They feed the chicks regurgitated food for the first couple of weeks after birth, and later they begin eating solid food as they grow. The parents also are a key part of teaching the young macaws how to fly and forage.
The glaucous Macaw has gone extinct, yet rumors of its existence continue to spread around the world. It is estimated that the glaucous Macaw was extinct in the 1800s due to the logging industry and cattle grazing in yatay palm (Butia yatay) areas, where the birds typically gathered their food. It is currently believed that the glaucous macaw has made a comeback in captivity in the wild, where it is kept with its larger cousin Lear's macaw.
In terms of habitat the glaucous macaw can be found in subtropical forests of South America. They are typically 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 defend the feeding and nesting area from intruders.
There have been a variety of reports involving the glaucous macaw over the years, but they are considered to be not reliable. The most recent wild claim was reported by an avicultural friend of Ridgely who claimed to have spotted four Glaucous Macaws in Califomia. This is a ridiculous claim until it is supported with hard evidence. The absence of any credible data on this bird over the last century has been a reason for many experts to conclude that it is likely extinct, but they have always been open to the possibility of existence (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it does survive it will be extremely uncommon to see large numbers.
Habitat
The Glaucous Macaw is a stunning bird, known for its huge size and turquoise-blue coloring. Its long tail and wings highlight its graceful and agile moves. The bird is an emblem of love and loyalty. Its beak, which is mostly black, has a distinct shape and allows it to crack seeds and nuts. These are a large part its diet.
The Glaucous Macaw is considered Critically Endangered by the IUCN and the IUCN states that it has an extremely small population and is at a high risk of extinction. The species was once widespread but is now 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, despite the fact that there were no reliable sightings since 1830. Specimens were collected up until 1860 (in Corrientes). The last known living Glaucous Macaw was displayed at the Buenos Aires Zoo in 1936 and is believed to be from Brazil.
A reassessment of the historical records suggests that this species was a more generalist in its habitat preferences, with a preference for the savanna ecosystem, which was interspersed with palm "islands" and bands of riparian forest along river systems. It was a specialized in the consuming of palm fruit especially those of the yatay (or chatay) palm (Butia). However it also ate ripe and unripe fruits, nuts, berries, and other vegetable matter. It nests on steep slopes, in cliffs and sometimes in tree cavities.
This bird was likely to be gregarious and social, similar to other parrots. It was said that it could live for up to 14.4 years in captivity, and was a reliable breeder that reproduced year after. In the wild, its life expectancy was probably 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 impact on its environment. This massive South American parrot is known for its bright blue feathers, bright yellow eyes and the teardrop-shaped lappet on the lower part its beak.
Up until recently, very little was known about eating habits and diet of the Glaucous macaw. The first references to the subject I have discovered are in two books by H.W. Bates, "The Naturalist on the Amazons" first published in 1863 about his 11 year sojourn in Brazil and later in his book "As Birds of the Brazilian Forests". Both of these references to the Hyacinthine Macaw (Anodorhynchus aureolarius), but I have no reason to believe that they are not applicable to this species.
It is likely that the Glaucous Macaw was a particular feeder of palm nuts and also took other seeds, fruits and vegetable matter in smaller quantities. The diet of this species is likely to be affected by the clearing of forests by the early colonists for agriculture and cattle ranching and the destruction of the yatay palm (Butia yatay) from which it may have gotten its majority of its diet.
In the wild, it was common to see the Glaucous macaw in savannahs and forests that were subtropical where palm trees were present. It was found in tree cavities, or on rocky banks and palm fronds. The female incubates and then lays two eggs on average.
The young Glaucous Macaws rely on their parents for care until they can fly and are fully full fledged. Both males and females are committed to their offspring and will hunt for food and defend them against predators.
Unfortunately the Glaucous Macaw has been eliminated from its entire former range. The disappearance of the magnificent bird is likely due to trapping that continues for the pet industry and disturbance of habitat, specifically the massive clearing of palm yatays which may have been its main food source. The Glaucous Macaw is classified as Critically Endangered.
Breeding
Glaucous macaws usually form long-term monogamous pairs, with both parents playing part in raising the young. They breed during the dry season, when food is plentiful. The female lays up to three eggs, which are incubated by the mother for approximately 28 days. In the initial few weeks following hatching, the chicks are fed daily by their parents through regurgitation. The young macaws then begin to explore their surroundings and learn how to eat themselves. They also learn how to fly and forage.
Like all birds, glaucous Macaws are highly social creatures. They are active during daylight hours, and rest at night. In the evening they usually seek refuge in tree cavities or other nesting areas that are suitable. They are extremely vocal and their calls can be heard throughout the forest during the day.
The species is expected to recover from the decline, but it is in danger of being wiped out by habitat loss, illegal trapping of the bird for the pet market, and deforestation. It is believed that there are only about 20 glaucous macaws that are in the wild. The IUCN classifies the bird as "Critically Endangered - possibly Extinct."
The glaucous Macaw is called the Lear's macaw, or the blue-throated hummingbird. It can be distinguished by its vivid blue feathers. It is a large parrot with a length of 70 centimeters and features a robust beak that is able to break open tough nuts and seeds. The beautiful bird is native to South America and can be found in diverse habitats, including grasslands, lowland forests and wetlands.
This majestic bird is a symbol of South American biodiversity. It has a regal look with its slim body, vibrant blue feathers, and a light build. Its black and curved beak allows it to break open seeds and nuts which are a large part of its diet. It is a beautiful bird that is often seen in bird here shows. It is also popular in captivity where it can live for a lifetime.
