Glaucous Macaw
The glaucous Macaw is one the rarest birds in the world. It is critically endangered and could even be extinct.
Many Aviculturalists have reported sightings of this bird, but the most recent was in 1992. The alleged sighting was reported to be in southwest Paraguay close to the city of Corrientes. The bird was male.
Origin
The Glaucous macaw is an endangered parrot species that is native to South America. This majestic bird is distinguished by a blue feather pattern, and a strong beak that can break open seeds and nuts. Glaucous Macaws form monogamous long-term pairs and both parents tend the chicks. The chicks are fed a diet of regurgitated food for the first couple of weeks of their lives and then a variety of solid foods as they grow. Parents also play a crucial role in teaching the young macaws how to fly and forage.
The glaucous Macaw is thought to be extinct in the wild, however rumors of this beautiful bird's existence persist all over the world. The Glaucous Macaw is believed have gone extinct in the 1800s due to cattle grazing on yatay (Butia) palm groves from which the birds gathered their food. It is believed that the glaucous Macaw has returned to captivity, where it is often kept alongside its larger cousin Lear's macaw.
In terms of habitat The glaucous macaw is able to be found in subtropical forests of South America. They are usually found in areas that have plenty of palm trees, and are known to be highly adaptable to various types of forested habitats. These beautiful birds are known to be very territorial and will defend their nesting and feeding areas from intruders.
There have been a lot of reports involving the glaucous macaw over the years, but most are considered to be not reliable. The most recent wild claim was made by an avicultural friend of Ridgely who claimed to have seen four Glaucous Macaws in Califomia. This is completely untrue until it is confirmed with hard evidence. The absence of any reliable records of this bird in the last century has caused many experts to think that it's likely extinct, yet they have always been willing to accept the possibility of existence (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it is able to survive, it is extremely unlikely to reach large numbers.
Habitat
The Glaucous Macaw is a magnificent bird, known for its large size and turquoise-blue coloring. check here and wings are long, enhancing its graceful and agile moves. The bird is an emblem of loyalty and love. Its beak, which is mostly black, has a distinct shape that allows it crack nuts and seeds. These are a large portion of its diet.
IUCN has classified the Glaucous Macaw as Critically Endangered. It notes that there is a very small population of this bird, and that it is at a the risk of becoming extinct. The species was previously quite widespread, but today it is found in northern Argentina as well as southern Paraguay and north-eastern Uruguay and Brazil from Parana state southwards. It was a nesting place in cliffs along major rivers.
The Glaucous Macaw was not rare in its relatively small area, even though there were no reliable sightings after 1830. The specimens were taken up until the year the year 1860 (in Corrientes). The last living Glaucous Macaw, believed to originate from Brazil was seen in the Buenos Aires Zoo back in 1936.
Re-evaluation of the historical records suggests that this species was a very generalist in its habitat preferences and preferred areas of savanna that were interspersed with palm "islands" and bands of riparian forest along rivers. It was a specific 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 fruits, nuts, berries and vegetable matter. It nestled on steep slopes and in cliffs, occasionally in tree cavities and laid an average clutch of two eggs.
As with other parrots this bird was social and probably gregarious. It could live up to 14.8 years in captivity and was believed to be a reliable breeder that reproduced year after year. macaw parrot cost in the wild was perhaps 50-80 years. This species was a powerful disperser of seeds, and could have contributed towards the success of the palm yatay species in its natural habitats.
Feeding
The Glaucous Macaw is one of the most beautiful parrots. Its presence has an enormous impact on the environment. This large South American parrot is known for its vibrant blue feathers, yellow eyes, and the teardrop-shaped lipped on its lower beak.
Up until recently, very little was known of the food habits and diet of the Glaucous macaw. The earliest references to this subject that I have located are two works by H.W. Bates, "The Naturalist on the Amazons" first published in 1863, detailing his 11 year sojourn in Brazil and later in his book "As Birds of the Brazilian Forests". Both of these refer to the Hyacinthine Macaw (Anodorhynchus aureolarius) however I see no reason to believe that they're not applicable to this species.
It is probable that the Glaucous Macaw was a specialist in the consumption of palm nuts, and also ate other seeds, fruits, and vegetable matter in small amounts. This species' diet was likely heavily influenced by the clearing of forests to cultivate cattle and the cattle-ranching practices of early colonists as well as the yatay (Butia) palms from which it received much of its nutrition.
In the wild, the Glaucous Macaw was often found in subtropical forests containing cliffs and savannahs with palm trees where it nested in tree cavities and on rocky banks or in the top of palm fronds. The female incubates and lays two eggs per.
The young Glaucous Macaws are altricial, meaning they rely on their parents to take care of them until they become fully grown and able to fly. Both females and males are extremely dedicated to their young and will continuously hunt for food and protect them from predators.
Unfortunately unfortunately, the Glaucous macaw is no longer present in the majority of its former habitat. The disappearance of this majestic bird is most likely due to the continuing trapping of pets for the pet trade as well as habitat disturbance, particularly the wholesale clearing of yatay palms from which it could have gotten its primary food source. The Glaucous macaw is listed under Critically Endangered.
Breeding
Glaucous macaws are typically monogamous couples with both parents taking an active role in the raising of the young. They breed during the dry season, which is when the food supply is at its highest. Females lay a clutch of two to three eggs that are incubated for about 28 days. In the initial few weeks following hatching, the chicks are fed by their parents via regurgitation. Macaws are then able exploring and learning to feed themselves. They are also taught how to fly and forage.
Like all birds, glaucous macaws are highly social creatures. They are active during daylight hours, and rest during the night. They often seek refuge in tree cavities or other suitable nesting sites to sleep. They are very vocal and their calls can be heard throughout the forest during the day.
The species is expected to recover from its decline, however it faces many threats including 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 has classified the bird as "Critically endangered, possibly extinct."
The glaucous macaw is called the Lear's macaw, or the blue-throated hummingbird. It is distinguished by its bright blue feathers. The parrot measures 70 centimeters long and has a powerful beak capable of slicing open seeds and nuts. This beautiful bird is native to South America, and it can be found in many habitats, including grasslands, forests, dry lowland, and wetland.
This majestic bird is a sign of South American biodiversity. It has a regal look with its slim body, vibrant blue feathers and its light build. Its black and curved beak allows it to break open seeds and nuts, which are a large part of its diet. It's a stunning bird, and it's often used in bird shows. It is also popular in captivity, where it can live for a long time.
