Glaucous Macaw
The glaucous Macaw is among the rarest birds in the world. It is critically endangered and could be extinct.
This bird has been reported by aviculturists from various countries however the most recent sighting was recorded in 1992. The reported sighting was in southwest Paraguay near the city Corrientes. The bird was male.
Origin
The Glaucous Macaw is a bird native to South America. It is endangered. This majestic bird is distinguished by a blue feather pattern, and a powerful beak that can break open seeds and nuts. Glaucous macaws have been known to form long-term monogamous pairs and both parents are involved in the raising of the chicks. The chicks are fed regurgitated food in the first few weeks of life, and then solid foods as the chicks develop. Parents are also responsible for teaching young macaws to fly and hunt.
The glaucous Macaw has gone extinct, but rumors about its existence persist around the world. The glaucous Macaw is believed to have gone extinct in the 1800s because of cattle grazing on yatay (Butia) palm groves, where the birds would gather their food. The Glaucous Macaw is believed have returned, and is often kept along with its larger cousin, Lear's macaw.
In terms of habitat The glaucous macaw is able to be found in sub-tropical forests of South America. They are most often located in areas with a lot of palm trees, and they are thought to be extremely adaptable to various types of forested habitats. These beautiful birds are territorial and defend the nesting and feeding area from intruders.
There have been a variety of reports involving the glaucous macaw throughout the years, but most are considered to be not reliable. The most recent claim of a wild event is an friend of Ridgely's that claimed to have witnessed four Glaucous macaws in Califomia. This is completely untrue until it is verified with solid evidence. Many experts have concluded that this bird is likely to be extinct since there are no records in the last century. However, they have always been willing to accept a slim chance of its survival. If it survives, it is extremely unlikely to be seen in huge numbers.
Habitat
The macaw with the glaucous is a striking bird that is renowned for its huge size and dazzling turquoise-blue coloring. The long tail and wings highlight its graceful and agile moves. This bird is also a symbol of love and loyalty. Its beak, which is primarily black, is distinctive in its shape that allows it break seeds and nuts. They are a significant portion of its diet.
IUCN has classified the Glaucous Macaw as Critically Endangered. It notes that there is only a tiny population of this bird and it is at risk of extinction. Fiona hyacinth macaw bird for sale was once widespread however, it is now found in northern Argentina and south Paraguay and north-eastern Uruguay, as well as Brazil and Brazil from Parana state to the south, where it nests in cliffs along major rivers.
The Glaucous Macaw was not rare in its relatively small range, despite the fact that there were no reliable sightings after 1830. There were specimens collected until the year 1860 (in Corrientes). The last living Glaucous Macaw, believed to be from Brazil, was exhibited in the Buenos Aires Zoo back in 1936.
The reassessment suggests that the species is a generalist, and prefers the savanna habitat, which is which is surrounded by palm "islands", and riparian forests along rivers. It was a specific eater of palm fruits, specifically those of the chatay or yatay palm (Butia yatay) however, it was likely to also feed on ripe and unripe fruit as well as berries, nuts and vegetable matter. It nests on slopes that are steep or in cliffs, and also in tree cavities.
This bird was likely to be gregarious and social, like other parrots. It was reported that it could live 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. The species was a strong disperser of seeds and may have contributed to the success of the palm yatay in its natural habitats.
Feeding
The Glaucous Macaw (Anodorhynchus glaucus) is among the most beautiful of the species of parrots, and its presence commands a powerful impact in its environment. This huge South American parrot is known for its bright blue feathers, yellow eyes and the teardrop-shaped lappet on the lower portion of its beak.
Up until recently, very little was known about feeding habits of the Glaucous Macaw. The first detailed references I have discovered are in two books by H.W. Bates' "The Naturalist on Amazons" first published in 1863, describes his 11-year journey in Brazil. Later, in his book "As Birds of the Brazilian Forests" He wrote about the similar experience. 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 feeder of palm nuts and also ate other seeds, fruits, and vegetable matter in small quantities. The diet of this species is likely to be influenced by the clearance of forests by early colonists for agriculture and cattle ranching, as well as the destruction of the yatay palm (Butia yatay) from which it may have received much of its diet.
In the wild the Glaucous Macaw was commonly found in subtropical forests containing the savannahs and cliffs surrounded by palm trees, where it nested in tree cavities and on rocky banks, or in the palm fronds' top. Females incubate and lay two eggs on average.
The young Glaucous Macaws rely on their parents for care until they fly and are fully full fledged. Both males and females are extremely committed to their offspring and will tirelessly hunt for food and protect them from predators.
Unfortunately the Glaucous Macaw has been eliminated from its entire former range. The disappearance of the majestic bird is likely due to the continued trapping of birds for the pet industry as well as habitat disruption, especially 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 are typically monogamous couples and both parents play a role in raising the young. They breed during the dry season, when the availability of food is at its highest. Females lay two to three eggs which are incubated by the mother for about 28 days. For the first few weeks after hatching, the chicks are fed by the parents via regurgitation. The young macaws then begin to explore their surroundings and begin to learn to feed themselves. They also learn how to fly and hunt for food.
Like all birds, glaucous macaws are extremely social creatures. They are active during daylight hours, and rest at night. At night, they will often seek refuge in tree cavities or other suitable nesting places. Their calls can be heard in the forest throughout the day.
The species is expected to rebound from the decline, but it is in danger of being wiped out by habitat loss and illegal trapping of the bird to sell on the pet market and deforestation. There are only about 20 glaucous Macaws that are believed to exist in the wild. The IUCN classifies the bird as "Critically Endangered--Possibly Extinct."
The glaucous Macaw is known as the Lear's macaw, or the blue-throated hummingbird. It can be distinguished by its vibrant blue feathers. It is a large bird, measuring 70 centimeters in length and has a sturdy beak that is able to break open hard nuts and seeds. The beautiful bird is native to South America and can be found in various habitats such as grasslands, lowland forests and wetlands.
This majestic bird is an emblem of South American biodiversity. It has a regal look with its slim body, bright blue feathers, and a light build. Its beak is curvaceous and black, which helps it open the nuts and seeds which comprise a significant portion 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 for a lifetime.
