Glaucous Macaw
The glaucous Macaw is one of the world's rarest birds. It is critically endangered and could be extinct.
The bird has been reported by aviculturists from various countries, but the latest sighting was recorded in 1992. The alleged sighting was reported to have occurred in the southwestern 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 is characterized by a blue feather pattern, and a strong beak capable of cracking open seeds and nuts. Glaucous Macaws live in monogamous pairs and both parents care for the chicks. They feed their chicks regurgitated food for the first few weeks after birth, and then they begin to eat solid foods as they develop. Parents are also responsible for teaching young macaws to fly and hunt.
The glaucous Macaw has gone extinct, but rumors about its existence continue to spread across the globe. It is estimated that the glaucous macaw was extirpated in the 1800s because of logging and cattle grazing of yatay palm (Butia yatay) areas, where the birds typically gathered their food. The glaucous Macaw is believed to have returned, and is usually kept with its larger mate, 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 with abundant palm trees, and they are believed to be extremely adaptable to various types of forested habitats. These beautiful birds are recognized as being very territorial and will defend their feeding and nesting areas from invaders.
There have been a lot of reports on the glaucous macaw over the years, but they are considered to be unreliable. The most recent claim of a wild incident is an avicultural acquaintance of Ridgely's who claimed to have seen four Glaucous macaws in Califomia. This is a ridiculous claim until it can backed up with evidence. The absence of any reliable data on this bird over the past century has led many experts to think that it's likely extinct, yet they have always been open to a remote possibility of its existence (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it is able to survive it is highly unlikely to make it to huge numbers.
Habitat
The macaw with the glaucous is a striking bird, renowned for its huge size and dazzling turquoise-blue coloring. Its long tail and wings accentuate its graceful and agile movements. The bird is an emblem of loyalty and love. Its beak is predominantly black and has a distinctive shape that allows it to open nuts and seeds, which constitute a significant part of its diet.
IUCN has classified the Glaucous Macaw as Critically Endangered. It states that there is only a tiny population of this bird, and that it is at a the risk of becoming extinct. The species was once widespread but is now found in northern Argentina, south Paraguay and north-eastern Uruguay as well as Brazil, from Parana state to south, where it is nestled in cliffs that run alongside major rivers.
The Glaucous Macaw was not rare in its small area, even though there were no reliable sightings after 1830. There were specimens taken up until the year the year 1860 (in Corrientes). The last living Glaucous Macaw believed to originate from Brazil, was exhibited in the Buenos Aires Zoo back in 1936.
The reassessment suggests that the species is a generalist, preferring areas of savanna that are that is interspersed with palm "islands" and riparian forest bands along river systems. It was a particular in the consuming of palm fruit, especially those of the yatay (or chatay) palm (Butia). However, it also ate ripe or unripe fruits as well as berries, nuts and other vegetable matter. It nested on steep slopes and cliffs, occasionally in tree cavities and laid an average clutch of two eggs.
This bird was likely gregarious and social, similar to other parrots. It could live up to 14.8 years in captivity and was believed to be a reliable breeder, reproducing year after year. In the wild, the lifespan was probably between 50 and 80 years. This species was a potent disperser of seeds and may have contributed to the success of the palm yatay species in its natural habitats.
Feeding
The Glaucous Macaw (Anodorhynchus glaucus) is one of the most magnificent of all the species of parrots and has a a powerful impact in its environment. This large South American parrot is known for its vibrant blue feathers, bright yellow eyes and the teardrop-shaped lappet on the lower portion of its beak.
Until recently very little was known about the diet of the Glaucous Macaw. The first detailed references 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 work "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 believed to have been a specialist feeder, taking only palm nuts, but also small amounts of other seeds, fruits and other matter. The diet of this species is likely to have been affected by the clearing of forests by early colonists for agriculture and cattle ranching as well as the destruction of the yatay palm (Butia yatay) from which it could have received much of its food.
In the wild the Glaucous Macaw was often found in subtropical forests with the savannahs and cliffs surrounded by palm trees where it nested in tree cavities, on rocky banks or the top of palm fronds. The female incubates and then lays two eggs on average.
The young Glaucous Macaws are altricial, meaning they rely on their parents to care for them until they are fully fledged and can fly. Both the male and female are extremely dedicated to their young and will tirelessly hunt for food and shield them from predators.
Unfortunately unfortunately, the Glaucous macaw has been found in most of its former habitat. The disappearance of this majestic bird is probably due to the continued trapping for the pet trade and habitat disturbance, particularly the mass removal of yatay palms which it may have obtained its main food supply. The Glaucous Macaw is classified as Critically Endangered.
Breeding
Glaucous macaws usually form long-term monogamous pairs, with both parents playing part in raising the young. They breed in the dry season when food availability is at its greatest. Females lay up to three eggs, which are incubated by the mother for approximately 28 days. After hatching they are fed by their parents through regurgitation for the first few weeks of life. The young macaws then begin to explore and learn to feed themselves. They also learn how to fly and hunt for food.
The glaucous Macaw is a highly social bird. They are active during daylight hours, and rest during the night. They often seek refuge in tree cavities or other nesting spots for the night. They are highly vocal, and their calls can be heard throughout the forest during the day.
The species is expected to rebound from the decline, but it faces many threats including habitat loss and illegal trapping of the bird to sell on the pet market and deforestation. It is estimated that there are hyacinth macaw parrots for sale less than 20 glaucous macaws that are in the wild. The IUCN classifies the bird as "Critically Endangered - possibly Extinct."
The glaucous Macaw, sometimes referred to as Lear's Macaw, or the blue-throated Hummingbird, is distinguished by its vibrantly blue feathers. The parrot measures 70 centimeters long and has a powerful beak capable of breaking open nuts and seeds. This gorgeous bird is native to South America, and it is found in various habitats such as grasslands, forests, dry lowland, and wetland.
This majestic bird is a symbol of South American biodiversity. It has a regal look with its slim body, vibrant blue feathers, and a light build. Its black and curved beak helps it crack open seeds and nuts, which are a large part of its diet. It's a beautiful bird, and it's often used in bird shows. It is also popular in captivity, where it can live for a long time.
