Glaucous Macaw
The glaucous macaw is considered to be one of the rarest birds on earth. It is Critically Endangered and could become extinct in the wild.
The bird has been reported by aviculturists across the globe however the most recent sighting was recorded 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 parrot native to South America. It is threatened. This magnificent bird features a distinctive blue feather pattern as well as a powerful beak capable of breaking open tough seeds and nuts. Glaucous Macaws live in monogamous couples and both parents tend the chicks. They feed the chicks regurgitated food for the first couple of weeks after birth, before they begin to eat 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 is extinct, but rumors about its existence continue to circulate across the globe. The Glaucous Macaw is believed be extinct by the 1800s because of the logging industry and cattle grazing in yatay (Butia) palm groves from which the birds would gather their food. The glaucous Macaw is believed to have returned, and is often kept with its larger cousin, Lear's macaw.
In terms of habitat the glaucous macaw can be found in sub-tropical 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 trespassers.
There have been a number of reports about the glaucous macaw throughout the years, but many are considered to be not reliable. The most recent claim of a wild incident is an friend of Ridgely's that claimed to have observed four Glaucous macaws in Califomia. This is completely untrue until it can be verified with hard evidence. The lack of any acceptable data on this bird over the last century has caused many experts to conclude that it is likely extinct, however they have always accepted the possibility of survival (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it survives, it is extremely unlikely to make it to huge numbers.
Habitat
The glaucous macaw is a striking bird, renowned for its huge size and stunning turquoise-blue coloring. Its long tail and wings highlight its graceful and agile movements. The bird is also a symbol of loyalty and love. Its beak is primarily black, and it has a unique shape that allows it to break open seeds and nuts, which comprise a large portion of its diet.
The Glaucous Macaw is considered Critically Endangered by the IUCN, which notes that it is a small population and is at a high danger of disappearing. The species was previously relatively widespread, but it is only 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 small area, despite the fact that there were no reliable sightings after 1830. The specimens were collected until 1860 (in Corrientes). The last living Glaucous Macaw, believed to originate from Brazil was seen in the Buenos Aires Zoo back in 1936.
Reassessment suggests that this species is a generalist and prefers areas of savanna that are that is interspersed with palm "islands" and bands of riparian forests along river systems. It was a specialist for the consumption of palm fruits especially those of the yatay (or chatay) palm (Butia). However, it also ate ripe and unripe fruits, nuts, berries, and even vegetable matter. It nestled on slopes and in cliffs, sometimes in tree cavities, and laid an average clutch of two eggs.
As with other parrots this bird was social and likely to be gregarious. It could live for up to 14.8 years in captivity and was believed to be a dependable breeder that reproduced year after year. In the wild, the lifespan was probably between 50 and 80 years. The species was a strong disperser of seeds, and could have contributed to the success of the palm yatay species in its natural habitat.
Feeding
The Glaucous Macaw (Anodorhynchus glaucus) is one of the most beautiful of the species of parrots, and its presence commands an enormous impact on its environment. This massive South American parrot is known for its vibrant blue feathers, bright yellow eyes, and the teardrop-shaped lipped on the lower part its beak.
As of the time of writing, little was known of the feeding habits and diet of the Glaucous macaw. The earliest detailed references I have found are in two works by H.W. Bates, "The Naturalist on the Amazons" first published in 1863 on his 11 year sojourn in Brazil and later in his book "As Birds of the Brazilian Forests". Both of these are about the Hyacinthine Macaw, Anodorhynchus Aureolarius. There is no reason to believe that they do not apply to this species.
The Glaucous macaw is likely have been a specialist eater, consuming only palm nuts, but also small amounts of other fruits, seeds and vegetable matter. 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 felling of the yatay palm (Butia yatay) from which it could have gotten its majority of its food.
In the wild it was commonplace to find the Glaucous macaw in savannahs and forests that were subtropical where palm trees were found. It nestled in tree cavities or on rocky banks and palm fronds. On average two clutches of eggs was laid and incubated by the female.
The young Glaucous Macaws are altricial, which means they depend on their parents to take care of them until they're fully click here grown and fly. Both females and males are extremely committed to their young and will constantly hunt for food and protect them from predators.
Unfortunately the Glaucous macaw isn't present in the majority of its former habitat. The disappearance of the majestic bird is likely due to the continued trapping of birds for the pet industry and disturbance to habitat, particularly the mass removal of palm yatays, which could have been their primary food source. The Glaucous Macaw is classified as Critically Endangered.
Breeding
Glaucous macaws are typically monogamous couples with both parents taking part in raising the young. They breed during the dry season, when food is plentiful. The female will lay up to three eggs, which are incubated by the mother for around 28 days. After hatching they are fed by their parents via regurgitation for the first few weeks of their life. Then the young macaws begin to explore their surroundings and learn to eat themselves. They also learn to fly and forage.
Like all birds, glaucous Macaws are extremely social creatures. They are active during daylight hours, and rest during the night. In the evening they often seek refuge inside tree cavities or other nesting spots that are suitable. 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, but it is facing numerous threats, including habitat loss illegal trapping of the bird to sell on the pet market and deforestation. It is estimated that there are only about 20 glaucous macaws 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 blue-throated Hummingbird is distinguished by its vibrantly blue feathers. The parrot is 70 centimeters long and has an impressive beak that is capable of cracking open nuts and seeds. This beautiful bird is native South America and can be found in a variety of habitats, including grasslands, lowland forests and wetlands.
This majestic bird is a symbol of South American biodiversity. It has a regal appearance, with its slender body, light weight and bright blue feathers. Its beak is curvaceous and black, which aids it open the seeds and nuts which comprise a significant portion of its diet. It is a beautiful bird that is often seen in birds shows. It is also popular in captivity where it can live a lifetime.
