Glaucous Macaw

The glaucous macaw is considered to be one of the rarest birds in the world. It is critically endangered and could be extinct.

The bird has been observed by aviculturists from various countries however the most recent sighting was in 1992. The reported sighting was in southwestern Paraguay, near the city of Corrientes. The bird was male.

Origin

The Glaucous Macaw is a bird native to South America. It is threatened. This magnificent bird is characterized by a blue feather pattern, and a strong beak that can break open seeds and nuts. Glaucous Macaws form monogamous long-term pair, and both parents raise the chicks. The chicks are fed a diet of regurgitated food for the first couple of weeks of their lives, and then solid foods as the chicks grow. Parents are also responsible for teaching the young macaws to fly and hunt.

The glaucous Macaw is extinct, but rumors about its existence persist all over 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 typically gathered their food. The Glaucous Macaw is believed be making a comeback and is often kept along with its larger relative, Lear’s macaw.

In terms of habitat The glaucous macaw is able to be found in the sub-tropical forests of South America. They are typically found in areas with numerous palm trees. They are also known to be very adaptable to various types of forested environments. These beautiful birds are territorial and will defend the nesting and feeding areas from intruders.

There have been a number of reports involving the glaucous macaw through the years, but they are considered to be unreliable. The most recent report of a wild incident is an friend of Ridgely's that claimed to have observed four Glaucous macaws in Califomia. This claim is completely unacceptable until it is confirmed by hard evidence. The absence of any credible 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 survival (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it survives, it is extremely unlikely to be seen in large numbers.

Habitat

The macaw glaucous is an impressive bird that is known for its large size and striking turquoise-blue coloration. The long tail and wings enhance its graceful and agile movements. The bird is an emblem of loyalty and love. Its beak, which is primarily black, is distinctive in its shape that allows it to crack seeds and nuts. They are a significant portion of its diet.

The Glaucous Macaw is considered Critically Endangered by the IUCN, which notes that it has an extremely small population and is at a high risk of extinction. This species was once widespread however, it is now found in northern Argentina, south Paraguay and north-eastern Uruguay, as well as Brazil and Brazil from Parana state to the south, where it nests in cliffs that run alongside major rivers.

The Glaucous Macaw was not rare in its small range, even though there was no proof of sightings since 1830. The specimens were taken up until the year 1860 (in Corrientes). The last known living Glaucous Macaw was exhibited at the Buenos Aires Zoo in 1936 and is believed to be from Brazil.

Reassessment suggests that this species is a generalist, and prefers areas of savanna that are which is surrounded by palm "islands" and bands of riparian forests along river systems. It was a specialised food source for palm fruits, specifically those of the chatay palm (Butia yatay) but it was also likely to consume unripe and ripe fruits, nuts, berries and vegetables. It nestled on steep slopes and in cliffs, sometimes in tree cavities and laid an average clutch of two eggs.

The bird was likely to be gregarious and social, like other parrots. It could live for up to 14.8 years in captivity. It was believed to be a reliable breeder that reproduced year after year. In the wild, its life expectancy was likely to be between 50 and 80 years. This species was a powerful seed disperser and may have contributed to the success of the yatay palm 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 surroundings. This huge South American parrot is known for its bright blue feathers, yellow eyes, and the teardrop-shaped lipped on the lower part its beak.

In the past, little was known about the eating habits 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 about his 11-year stay in Brazil and later in his book "As Birds of the Brazilian Forests". Both of these references 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 specialized in the consumption of palm nuts, and also consumed other seeds, fruits, and vegetable matter in smaller amounts. The diet of this species is likely to have been influenced by the clearance of forests by early colonists for agriculture and cattle ranching, as well as the removal of the yatay palm (Butia yatay) from which it may have gotten a lot of its diet.

In the wild the Glaucous Macaw was commonly found in subtropical forests with cliffs and savannahs with palm trees where it nested in tree cavities and on rocky banks or in the top of palm fronds. The female incubates and lays two eggs on average.

The young Glaucous Macaws rely on their parents for care until they fly and fully fledged. Both males and females are very committed to their offspring and hunt for food and defend them against predators.

Unfortunately unfortunately, the Glaucous Macaw has been extirpated from the majority of its previous range. The disappearance of this magnificent bird is probably due to the continuing trapping for the pet trade, as well as disturbance to habitat, specifically the wholesale clearing of yatay palms from which it could have gotten its main food supply. The Glaucous macaw is listed under Critically Endangered.

Breeding

Glaucous macaws typically form long-term monogamous pairs and both parents play a role in raising the young. They breed in the dry season, when food is plentiful. Females lay two to three eggs which are incubated by the mother for approximately 28 days. When the chicks are born they are fed by their parents through regurgitation for the first few weeks of their life. Macaws are then able exploring and learning to feed themselves. They also learn to fly and hunt for food.

Like all species of birds, glaucous macaws are social animals. They are active during daylight hours and take a break at night. They often seek refuge in cavities in trees or other nesting spots to sleep. Their calls can be heard throughout the forest throughout the day.

The species is expected to recover from its decline, however it is in danger of being wiped out by habitat loss illegal trapping of the bird for pet trade, buymacaw and deforestation. It is believed that there are just 20 glaucous macaws living in the wild. The IUCN has classified the bird as "Critically endangered, possibly extinct."

The glaucous macaw is called the Lear's macaw or blue-throated hummingbird. It is distinguished by its bright blue feathers. It is a large bird, measuring 70 centimeters long and has a sturdy beak that can crack open tough nuts and seeds. This beautiful bird is native South America and can be found in diverse habitats that include grasslands, lowland forests and wetlands.

This majestic bird is an emblem of South American biodiversity. Its elegant appearance is reflected with its slim body, vibrant blue feathers, and lightweight build. The beak is curved and black, which aids it break open the seeds and nuts that comprise a large portion of its diet. It is a stunning bird and is often used in bird shows. It is also popular in captivity, where it can live for a lifetime.
