Glaucous Macaw
The glaucous macaw is considered to be one of the rarest birds in the world. It is critically endangered and may even be extinct.
Various aviculturalists have reported sightings of this bird however the most recent sighting was in 1992. The reported sighting was in southwestern Paraguay close to the city of Corrientes. The bird was a male.
Origin
The Glaucous Macaw is a parrot native to South America. It is threatened. This majestic bird is distinguished by the blue feather pattern and a strong beak that can break open nuts and seeds. Glaucous macaws are known to form long-term monogamous families and both parents are involved in the raising of the chicks. They feed their chicks regurgitated food for the first couple of weeks after birth, and later they begin eating solid foods as they develop. Parents are also responsible for teaching the young macaws to fly and hunt.
The glaucous Macaw is extinct, but rumors about its existence persist around the world. It is believed that the glaucous macaw extirpated in the 1800s because of cattle grazing and logging in yatay palm (Butia yatay) groves, where these birds mostly ate their food. It is currently believed that the glaucous macaw returned to captivity in the wild, where it is kept alongside its larger cousin, Lear's macaw.
In terms of habitat the glaucous macaw can be found in the sub-tropical forests of South America. They are usually located in areas with numerous palm trees. They are also very adaptable to various types of forest habitats. These beautiful birds can be territorial and will protect the nesting and feeding areas from intruders.
In the past, there have been numerous reports of 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 can backed up with evidence. Many experts have concluded that the bird is likely extinct as 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 will be extremely rare to observe large numbers.
Habitat
The macaw with the glaucous is a striking bird, renowned for its large size and stunning turquoise-blue coloring. The tail and wings are long, which aids in its graceful and agile moves. It is also an emblem of loyalty and love. Its beak is mostly black, and it is distinctive in its shape. It allows it to break open nuts and seeds, which make up a large portion of its diet.
The Glaucous Macaw is considered Critically Endangered by the IUCN and the IUCN states that it has a small population and is at a significant danger of disappearing. This species was formerly quite widespread, but today it is found only in northern Argentina as well as southern Paraguay, north-eastern Uruguay and Brazil from Parana state southwards, where 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 since 1830. The specimens were collected until 1860 (in Corrientes). The last known living Glaucous Macaw was seen at the Buenos Aires Zoo in 1936 and is believed to be from Brazil.
Reassessment suggests that this species is a generalist and prefers savanna habitat which is surrounded by palm "islands", and bands of riparian forests along rivers. It was a specialist in the consuming of palm fruit especially those of the yatay (or chatay) palm (Butia). However it also ate ripe or unripe fruits and berries, nuts, and even vegetable matter. It nests on slopes that are steep on cliffs, in cliffs, and occasionally in tree cavities.
As with other parrots this bird was social and was likely to be sociable. It was able to live up to 14.8 years in captivity and was said to be a dependable breeder that reproduced year after year. The life expectancy of this species in the wild was 50-80 years. This species was a potent seed disperser and may have contributed to the success of the yatay palm within its natural habitats.
Feeding
The Glaucous Macaw (Anodorhynchus glaucus) is one of the most beautiful of the species of parrots and its presence has an enormous impact on its surroundings. This huge South American bird is known for its vibrant blue feathers and yellow eyes and also for its distinctive teardrop-shaped lappet which adorns the lower portion of its beak.
Until recently very little was known about feeding habits 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 stay in Brazil and later in his book "As Birds of the Brazilian Forests". Both of these refer to the Hyacinthine Macaw (Anodorhynchus aureolarius), but I have no reason to think that they are not applicable to this species.
The Glaucous macaw is likely to have been a specialist feeder, consuming mainly palm nuts however, there were also small amounts of other seeds, fruits and other matter. This species' diet was likely affected by the clearing of forests for agriculture and cattle-ranching by early colonists, as well the removal of yatay (Butia) palms from which it got a large portion of its nutritional value.
In the wild, the Glaucous Macaw was often found in subtropical forests that had cliffs and savannahs with palm trees, where it nestled in tree cavities, on rocky banks or the palm fronds' top. The female incubates and then lays two eggs on average.
The young Glaucous Macaws are altricial, which means they depend on their parents to look after them until they're fully grown and fly. Both males and females are extremely dedicated to their offspring and constantly hunt for food and protect them from predators.
Unfortunately, the Glaucous Macaw has been eradicated from its entire former range. The disappearance of the majestic bird is likely due to trapping that continues for the pet industry and habitat disruption, especially the mass removal of palm yatays, which may have been its main food source. The Glaucous macaw is listed as Critically Endangered.
Breeding
Glaucous macaws typically form long-term monogamous couples, with both parents chestnut fronted macaw playing a role in raising the young. They breed in the dry season, when food is most abundant. The female will lay two to three eggs which are incubated by the mother for about 28 days. After hatching they are fed by their parents through regurgitation for the first couple of weeks of their life. Macaws are then able to explore and to feed themselves. They are also taught to fly and forage.
The glaucous Macaw can be described as a extremely social bird. They are active during daylight hours, and take a break at night. They usually seek shelter in cavities in trees or other suitable nesting sites for the night. They are very vocal and their calls can be heard throughout the forest during the day.
The species is expected to rebound from the decline, however it is facing numerous threats, including habitat loss and illegal trapping of the bird for 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 also known as Lear's Macaw, or the blue-throated Hummingbird is distinguished by its bright blue feathers. It is a large parrot, measuring 70 centimeters in length and features a robust beak that can crack open seeds and nuts that are tough to break. This beautiful bird is native to South America, and it is found in various habitats, including grasslands, forests, dry lowland and wetland.
This majestic bird is a symbol of South American biodiversity. Its appearance is elegant with its slender body, bright blue feathers and its light build. Its black and curved beak allows it to break open nuts and seeds, which are a large part of its diet. It's a stunning bird, and it's often used in bird shows. It is also a favourite in captivity, where it can be kept for a lifetime.
