Glaucous Macaw
The glaucous Macaw is one of the world's rarest birds. It is in serious danger and could even be extinct.
The bird has been reported by aviculturists in various countries, but the latest sighting was recorded in 1992. The reported sighting was in the southwest region of Paraguay close to the city of Corrientes. The bird was male.
Origin
The Glaucous Macaw is a bird native to South America. It is endangered. This magnificent bird is characterized by the blue feather pattern and a powerful beak that is capable of breaking open seeds and nuts. Glaucous macaws form long-term monogamous families and both parents help raise the chicks. They feed their chicks regurgitated food for the first couple of weeks after birth, and later they begin eating solid food as they grow. Parents are also responsible for teaching the young macaws to fly and hunt.
The glaucous Macaw has gone extinct, but rumors about its existence persist all over the world. It is believed that the glaucous macaw extirpated in the 1800s because of the logging industry and cattle grazing in yatay palm (Butia yatay) trees, where these birds typically gathered their food. The glaucous Macaw is believed to have returned, and is usually kept with its larger cousin, Lear's macaw.
The glaucous Macaw can be found in sub-tropical rainforests in South America. They are typically found in areas with abundant palm trees, and they are known to be highly adaptable to different types of forested habitats. These beautiful birds are also recognized as being very territorial and will protect their feeding and nesting areas from invaders.
Over the years there have been numerous reports of the glaucous macaw however they are generally not considered reliable. The most recent report of a wild occurrence involves an avicultural acquaintance of Ridgely's who claimed to have seen four Glaucous macaws in Califomia. This claim is unacceptable until it is substantiated with evidence. The absence of any credible data on this bird over the last century has been a reason for many experts to conclude that it is 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 is able to survive, it will be extremely uncommon to witness large numbers.
Habitat
The macaw with the glaucous is a striking bird, renowned for its large size and dazzling turquoise-blue coloring. The tail and wings are long, enhancing its fluid and graceful moves. The bird is also an emblem of affection and loyalty. Its beak is mostly black, and it is distinctive in its shape. It allows it to break open seeds and nuts which make up a large part of its diet.
The Glaucous Macaw is considered Critically Endangered by the IUCN which states that it has a small population and is at a significant risk of extinction. This 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 resides in cliffs along major rivers.
The Glaucous Macaw was not rare in its limited area, despite the fact that there was no evidence of sightings after 1830. The specimens were taken up until the year 1850 (in Corrientes). The last living Glaucous Macaw, believed to originate from Brazil was seen in the Buenos Aires Zoo back in 1936.
A re-examination of the historical documents suggests that this species was more generalist in its preferences for habitat and preferred savanna habitat intermingled with palm "islands" and bands of riparian forest along river systems. It was a particular food source for palm fruits, especially those of the chatay palm (Butia yatay), but it could also consume unripe and ripe fruits, nuts, berries and vegetable matter. It nestled on slopes and cliffs, sometimes in tree cavities and laid an average clutch of two eggs.
This bird was likely gregarious and social, like other parrots. It could live up to 14.8 years in captivity. It was said to be a reliable breeder, reproducing year after year. In the wild, the lifespan was likely to be between 50 and 80 years. This species was a potent disperser of seeds and could have contributed to the success of the palm yatay in its natural habitats.
Feeding
The Glaucous Macaw is one of the most stunning buying a macaw online parrots. Its presence can have a strong impact on the environment. This massive South American bird is known for its vivid blue feathers and yellow eyes and also for its distinctive teardrop-shaped lappet which adorns the lower part of its beak.
In the past, little was known about eating habits of the Glaucous Macaw. The first detailed references I have come across are two works by H.W. Bates, "The Naturalist on the Amazons" first published in 1863, detailing his 11 year sojourn 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're not applicable to this species.
It is probable that the Glaucous Macaw was a particular in the consumption of palm nuts, and also ate other seeds, fruits, and vegetable matter in small amounts. 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 removal of the yatay palm (Butia yatay) from which it may have received much of its food.
In the wild the Glaucous Macaw was often found in subtropical forests that had mountains and savannahs that were surrounded by palm trees, where it nested in tree cavities, on rocky banks or in the palm fronds' top. The female incubates and then lays two eggs per.
The young Glaucous Macaws rely on their parents to provide care until they are able to fly and are fully grown. Both the male and female are extremely committed to their offspring and will constantly hunt for food and protect them from predators.
Unfortunately, the Glaucous macaw is no longer found in its former habitat. The disappearance of the majestic bird is likely due to continued trapping for the pet industry as well as disturbance to habitat, particularly the wholesale removal of palm yatays that may have been its main food source. The Glaucous macaw is listed under Critically Endangered.
Breeding
Glaucous Macaws are monogamous, long-term pairs. Both parents are involved in the raising of their young. They breed in the dry season when food availability is at its greatest. Females lay an egg clutch of between two and three eggs, which are incubated for about 28 days. For the first few weeks after hatching the chicks are fed daily by their parents through regurgitation. Then the young macaws begin to explore their surroundings and learn how to eat themselves. They also learn to fly and forage.
Like all species of birds, glaucous macaws are highly social creatures. They are active during the day, but sleep at night. During the night they often seek shelter inside tree cavities or other nesting spots that are suitable. Their calls can be heard throughout the forest throughout the day.
The species is expected to recover from the decline, however it is facing numerous threats, including habitat loss, illegal trapping of the bird for the pet market, and deforestation. Only about 20 glaucous Macaws are estimated to be living in the wild. The IUCN classifies the bird as "Critically Endangered--Possibly Extinct."
The glaucous macaw, sometimes referred to as Lear's Macaw or Blue-throated Hummingbird is distinguished by its bright blue feathers. It is a large bird, measuring 70 centimeters long and has a sturdy beak that can break open seeds and nuts that are tough to break. This beautiful bird is native to South America, and it can be found in many habitats such as forests, dry lowland grasslands, and wetlands.
This magnificent bird is a sign of South American biodiversity. Its elegant appearance is reflected with its slim body, bright blue feathers and its light build. The beak is curved and black, which aids it open the nuts and seeds which comprise a significant portion of its diet. It's a beautiful bird, and it is often seen in bird shows. It is also a favorite in the wild, where it can be kept for a lifetime.
