Glaucous Macaw The glaucous macaw is considered to be one of the world's rarest birds. It is Critically Endangered and could become extinct in the wild. Various Aviculturalists have reported sightings of this bird, but the most recent was in 1992. This alleged sighting was in the southwest region of Paraguay near the city Corrientes. The bird was male. Origin The Glaucous Macaw is a bird native to South America. It is endangered. This magnificent bird has a distinctive blue feather pattern and a powerful beak capable of breaking open tough nuts and seeds. Glaucous macaws form long-term monogamous families and both parents assist in raising the chicks. They feed the chicks a diet of regurgitated food for the first few weeks after birth, and later they begin eating solid foods as they develop. The parents also play a crucial role in teaching the young macaws how to fly and forage. The glaucous Macaw has gone extinct, yet rumors of its existence continue to spread all over the world. The Glaucous Macaw is believed have gone extinct in the 1800s because of cattle grazing on yatay (Butia) palm groves, where the birds would gather their food. It is currently believed that the glaucous macaw made a comeback in captivity and is usually 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 typically located in areas with many palm trees. They are also known to be very adaptable to various types of forest habitats. These beautiful birds are also known to be very territorial and will defend their feeding and nesting areas from invaders. There have been a number of reports about the glaucous macaw through 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 claim is untrue until it is substantiated with hard evidence. The absence of any credible records of this bird in the past century has been a reason for many experts to believe that it is extinct, but they have always accepted the possibility of survival (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it survives it will be very rare to see large numbers. Habitat The macaw with the glaucous is a striking bird, renowned for its large size and stunning turquoise-blue coloration. The long tail and wings accentuate its graceful and agile movement. The bird is a symbol of love and loyalty. Its beak is predominantly black and has a distinctive shape that allows it to crack open seeds and nuts, which make up a large part of its diet. IUCN has classified the Glaucous Macaw as Critically Endangered. It states that there is a tiny population of this bird and it is at the risk of becoming extinct. This species was once widespread however, it is now found in northern Argentina south Paraguay and north-eastern Uruguay as well as Brazil, from Parana state to the south, where it nests in cliffs alongside major rivers. The Glaucous Macaw was not rare in its small range, even though there were no reliable sightings since 1830. The specimens were collected until 1850 (in Corrientes). The last known living Glaucous Macaw was exhibited at the Buenos Aires Zoo in 1936 and is believed to have come from Brazil. A reassessment of the historical documents suggests that this species was rather generalist in its preferences for habitat, with a preference for the savanna ecosystem, which was interspersed with palm “islands” and bands of riparian forest along rivers. It was a particular for the consumption of palm fruits especially those of the yatay (or chatay) palm (Butia). However it also ate ripe and unripe fruits and berries, nuts, and even vegetable matter. It nestled on steep slopes and in cliffs occasionally in tree cavities and laid an average clutch of two eggs. Like all parrots, this bird was social, and was probably gregarious. It was said that it could live for up to 14.4 years in captivity, and was a reliable breeder who reproduced year after year. The lifespan of the species in the wild was 50-80 years. This species was a formidable seed disperser and may 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 can have an influence on the surrounding. This large South American parrot is known for its vibrant blue feathers, yellow eyes and the teardrop-shaped lappet on the lower part its beak. Up until recently, very little was known of the food habits and diet of the Glaucous macaw. The first references to the subject I have found are in two publications 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 have no reason to believe that they're not applicable to this species. The Glaucous macaw is believed to be a specialist eater, consuming only palm nuts as well as tiny amounts of other seeds, fruits and vegetable matter. The diet of this species was likely affected by the clearing of forests to cultivate cattle and the cattle-ranching practices of early colonists, as well the yatay (Butia) palms from which it got a large portion of its nutritional value. In Blondie scarlet macaw bird was found in subtropical forests containing mountains and savannahs that were 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 are altricial, which means they depend on their parents to look after them until they're fully fledged and can fly. Both females and males are extremely dedicated to their offspring and will tirelessly hunt for food and shield them from predators. Unfortunately, the Glaucous Macaw has been eradicated from most of its former range. The disappearance of the magnificent bird is likely to be due to the continued trapping of birds for the pet industry, as well as habitat disruption, especially the massive removal of palm yatays that may have been its main food source. The Glaucous macaw is listed as Critically Endangered. Breeding Glaucous Macaws form monogamous long-term couples. Both parents are involved in the raising of their young. They breed during the dry season, which is when food is most abundant. Females lay a clutch of two to three eggs that are incubated for around 28 days. For the first few weeks after hatching the chicks are fed by their parents via regurgitation. The macaws' young begin to explore their surroundings and begin to learn to eat themselves. They also learn to fly and hunt for food. The glaucous Macaw can be described as a very social bird. They are active during daylight hours, and rest at night. At night they usually seek refuge in tree cavities or other nesting areas that are suitable. They are very vocal and their calls can be heard throughout the forest during the day. While it is hoped that the species will be able to recover from its decline in the wild, the bird faces many threats, including loss of habitat, illegal trapping for the pet trade, and deforestation. It is estimated that there are just 20 glaucous macaws that are in the wild. The IUCN has classified the bird as “Critically endangered—possibly extinct.” The glaucous Macaw, also known as Lear's Macaw or blue-throated Hummingbird is distinguished by its vivid blue feathers. It is a large bird, measuring 70 centimeters long and features a robust beak that can break open seeds and nuts that are tough to break. The beautiful bird is native to South America and can be found in diverse habitats such as forests, lowland grasslands and wetlands. This majestic bird is a symbol of South American biodiversity. Its appearance is elegant, with its slender body, light weight, and vibrant blue feathers. Its beak is curved and black, which aids it open the seeds and nuts which comprise a significant portion of its diet. It is a stunning bird and is often used in birds shows. It is also popular in captivity where it can live for a long time.
