Glaucous Macaw
The glaucous Macaw is among the rarest birds in the world. It is in danger of disappearing and could even be extinct.
Many aviculturalists have reported sightings of this bird However, the most recent sighting was in 1992. This alleged sighting was in the southwest region of Paraguay close to the city of Corrientes. The bird was male.
Origin
The Glaucous macaw is a threatened parrot species native to South America. This magnificent bird has a distinctive blue feather pattern as well as a powerful beak capable of breaking open tough nuts and seeds. Glaucous macaws have been known to form long-term monogamous couples and both parents help raise the chicks. The chicks are fed regular food during the first few weeks of life and then a variety of solid foods as the chicks grow. 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 around the world. The Glaucous Macaw is believed have been extinct in the 1800s due to logging and cattle grazing on yatay (Butia) palm groves from which the birds gathered their food. The Glaucous Macaw is believed have made a comeback, and is often kept along with its larger cousin, Lear's macaw.
The glaucous Macaw lives in sub-tropical rainforests of South America. They are usually found in areas with abundant palm trees, and are known to be highly adaptable to different types of forested habitats. These beautiful birds can be territorial and will defend the feeding and nesting area from intruders.
There have been a variety of reports on the glaucous macaw through the years, but many are considered to be not reliable. The most recent wild claim was reported by an avicultural friend of Ridgely 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 records of this bird in the last century has caused many experts to believe that it is extinct, yet they have always been willing to accept the possibility of existence (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it survives it will be very uncommon to observe large numbers.
Habitat
The glaucous macaw is a striking bird that is known for its huge size and dazzling turquoise-blue coloring. The tail and wings are long, enhancing its fluid and graceful movements. The bird is an emblem of loyalty and love. Its beak is mostly black and has a distinctive shape that allows it to open seeds and nuts which constitute a significant part of its diet.
IUCN has classified the Glaucous Macaw as Critically Endangered. It states that there is a very tiny population of this bird and it is in risk of extinction. The species was once fairly widespread but now it is only found in northern Argentina as well as southern Paraguay, north-eastern Uruguay and Brazil from Parana state southwards, where it nestted in cliffs along major rivers.
The Glaucous Macaw was not rare in its relatively small area, even though there was no evidence of sightings after 1830. There were specimens taken up until the year 1860 (in Corrientes). The last known living Glaucous Macaw was seen at the Buenos Aires Zoo in 1936 and is believed to have come from Brazil.
A reassessment of the historical records suggests that this species was a more generalist in its preferences for habitat, with a preference for the savanna ecosystem, which was interspersed with palm "islands" and forests of riparian along river systems. It was a specialised eater of palm fruits, particularly those of the yatay or chatay palm (Butia yatay) however, it was likely to also consume unripe and ripe fruits as well as berries, nuts and vegetable matter. It nestled on slopes and cliffs, sometimes in tree cavities, and laid an average clutch of two eggs.
Like other parrots, this bird was social and was likely to be sociable. It could live up to 14.8 years in captivity and was believed to be a dependable breeder that reproduced year after year. In the wild, its lifespan was probably between 50 and 80 years. This species was a potent seed disperser, and could have contributed to the success of the yatay palm in its native habitats.
Feeding
The Glaucous Macaw is one of the most stunning parrots. Its presence can have a strong impact on the environment. This large South American bird is known for its vibrant blue feathers and eyes that are yellow, as well as its distinctive teardrop-shaped lipped sleeve that covers the lower part of its beak.
In the past, little was known about the diet 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 same experience. Both of these refer to the Hyacinthine Macaw (Anodorhynchus aureolarius) However, I have no reason to believe that they are not applicable to this species.
The Glaucous macaw is believed to be a specialist feeder, consuming mainly palm nuts as well as tiny amounts of other fruits, seeds and vegetable matter. This species' diet was likely affected by the clearing of forests to cultivate cattle and the cattle-ranching practices of early colonists, as well the felling of yatay (Butia) palms from which it received much of its nutrition.
In the wild, it was common to find the Glaucous macaw in subtropical forests and savannahs in which palm trees were present. It nestled in tree cavities, or on rocky banks or palm fronds. The female incubates and lays two eggs on average.
The young Glaucous Macaws rely on their parents to provide care until they fly and are fully fledged. Both males and females are extremely committed to their young and will tirelessly hunt for food and defend them from predators.
Unfortunately, the Glaucous Macaw has been extirpated from the majority of its previous range. The disappearance of this magnificent bird is likely to be due to trapping that continues for the pet industry, as well as disturbance to habitat, particularly the mass clearing of palm yatays which may have been its main food source. The Glaucous macaw is listed under Critically Endangered.
Breeding
Glaucous Macaws are monogamous, long-term couples. Both parents are involved in the raising of their young. They breed during the dry season when food availability is at its highest. The female lays two to three eggs which are incubated by the mother 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 forage.
Like all birds, glaucous macaws are social animals. They are active during daylight hours and rest during the night. They often seek refuge in tree cavities or other suitable nesting sites to sleep. Their calls can be heard throughout the forest throughout the day.
While it is believed that the species will be able to recover from its decline in the wild, the bird faces numerous threats, including the loss of habitat illegal trapping for the pet trade, and deforestation. It is estimated that there are only about 20 glaucous macaws in the wild. The IUCN has classified 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 vivid blue feathers. It is a large bird, measuring 70 centimeters in length and features a Ziggy Our Scarlet Macaw robust beak that can crack open seeds and nuts that are tough to break. The beautiful bird is native to South America and can be found in a variety of habitats such as forests, lowland grasslands and wetlands.
This majestic bird is a symbol of South American biodiversity. It has a regal appearance, with its slender body, light build, and vibrant blue feathers. Its beak is curvaceous and black, which helps it open the nuts and seeds that comprise a large portion of its diet. It is a great-looking bird, and is often seen in shows featuring birds. It is also a favorite in captivity, where it can remain for a long time.
