Glaucous Macaw
The glaucous Macaw is among the rarest birds in the world. It is considered Critically Endangered, and may be extinct in the wild.
A variety of Aviculturalists have reported sightings of this bird, but the most recent was in 1992. The alleged sighting was reported to have occurred in southwestern 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 features a distinctive blue feather pattern and a powerful beak that is capable of breaking open hard seeds and nuts. Glaucous macaws form long-term monogamous pairs and both parents assist in raising the chicks. They feed their chicks regurgitated food for the first couple of weeks after birth, and then they begin to eat solid foods as they develop. Parents play a crucial role in teaching the young macaws how to fly and forage.
The glaucous macaw is believed to be extinct in the wild, but reports of this beautiful bird's existence continue to spread across the globe. It is estimated that the glaucous macaw extinct in the 1800s due to logging and cattle grazing of yatay palm (Butia yatay) trees, where these birds primarily gathered their meals. It is currently believed that the glaucous macaw has made a comeback in captivity, where it is often kept with its larger cousin, Lear's macaw.
In terms of habitat the glaucous macaw can be found in the sub-tropical forests of South America. They are typically found in areas with abundant palm trees, and they are thought to be extremely adaptable to different types of forested habitats. These beautiful birds are recognized as being very territorial and will protect their feeding and nesting areas from intruders.
Over the years there have been many reports of the glaucous macaw, but they are generally not considered reliable. The most recent claim of a wild event is an avicultural acquaintance of Ridgely's who claimed to have witnessed four Glaucous macaws in Califomia. This claim is untrue until it is supported with hard evidence. The absence of any reliable data on this bird over the last century has been a reason for many experts to think that it's likely extinct, yet they have always accepted an extremely remote possibility of its survival (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it survives, it is extremely unlikely to make it to large numbers.
Habitat
The Glaucous Macaw is a stunning bird, known for its size and turquoise-blue coloring. Its long tail and wings accentuate its graceful and agile movement. It is also a symbol of affection and loyalty. Its beak, which is primarily black, has a distinct shape that allows it to break seeds and nuts. They form a large part 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 in 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 the south, where it is nestled in cliffs alongside major rivers.
While there have been no credible sightings of the species since 1830, the Glaucous Macaw seemed not to be very rare in its limited range. specimens were captured from 1830 to 1860 (in Corrientes). The last living Glaucous Macaw believed to originate from Brazil was displayed in the Buenos Aires Zoo back in 1936.
Reassessment suggests that this species is a generalist and prefers the savanna habitat, which is which is surrounded by palm "islands", and riparian forest bands along rivers. It was a specialized for the consumption of palm fruits, especially those of the yatay (or chatay) palm (Butia). However, it also ate ripe or unripe fruits as well as berries, nuts and even vegetable matter. It nests on slopes that are steep, in cliffs and sometimes in tree cavities.
Like all parrots, this bird was social, and was likely to be gregarious. It could live up to 14.8 years in captivity. It was said to be a reliable breeder, reproducing year after year. The lifespan of the species in the wild was perhaps between 50 and 80 years. This species was a potent seed disperser and may have contributed to the success of the yatay palm in its natural habitats.
Feeding
The Glaucous Macaw is one of the most beautiful parrots. Its presence can have an enormous impact on the environment. This massive South American bird is known for its vibrant blue feathers and eyes that are yellow, and also for its distinctive teardrop-shaped lipped sleeve that covers the lower portion of its beak.
Up until recently, very little was known about eating habits of the Glaucous Macaw. The earliest references to this subject that I have found are two works 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 similar experience. Both of these refer to the Hyacinthine Macaw (Anodorhynchus aureolarius) however I see no reason to think that they're not applicable to this species.
It is likely that the Glaucous Macaw was a specialist in the consumption of palm nuts, and also consumed other seeds, fruits and vegetable matter in smaller quantities. The diet of this species was likely influenced by the clearing of forests to cultivate cattle and the cattle-ranching practices of early colonists, and the removal of yatay (Butia) palms from which it derived a lot of its nutritional value.
In the wild, it was common to find the Glaucous macaw in subtropical forests and savannahs where palm trees were present. It hid in tree cavities, or on rocky banks or palm fronds. Females incubate and lay two eggs on average.
The young Glaucous Macaws rely on their parents for care until they can fly and are fully full fledged. Both males and females are dedicated to their offspring, and hunt for food and defend them from predators.
Unfortunately unfortunately, the Glaucous macaw has been found in its former habitat. The disappearance of this majestic bird is most likely due to the ongoing trapping for the pet trade and disturbance of habitat, especially the massive clearing of yatay palms from which it could have gotten its primary food source. The Glaucous macaw is classified as Critically Endangered.
Breeding
Glaucous macaws usually form long-term monogamous pairs and both parents play a role in raising the young. They breed during the dry season when food availability is at its highest. Females lay an egg clutch that ranges from two to three eggs, which are incubated for a period of around 28 days. In the initial few weeks after hatching, the chicks are fed daily by their parents through regurgitation. The young macaws then begin to explore their surroundings and learn how to feed themselves. They also learn to fly and hunt for food.
Like all birds, glaucous Macaws are social animals. They are active during the day and are restful at night. They usually seek shelter in cavities in trees or other suitable nesting places 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 illegal trapping of the bird for the pet market, more info and deforestation. It is believed that there are only about 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 the blue-throated hummingbird. It is distinguished by its vivid blue feathers. The parrot is 70 centimeters long and features a an impressive beak that is capable of cracking open seeds and nuts. This beautiful bird is native to South America, and it is found in a variety of habitats like forests, dry lowland grasslands and wetlands.
This majestic bird is a sign of South American biodiversity. It has a regal look with its slender body, vibrant blue feathers, and a light build. Its beak is curvaceous and black, which aids it crack open the nuts and seeds which comprise a significant portion of its diet. It's a beautiful bird, and it is often featured in shows featuring birds. It is also popular in captivity where it can live for a long time.
