Glaucous Macaw
The glaucous Macaw is one of the world's rarest birds. It is critically endangered and may even be extinct.
A variety of Aviculturalists have reported sightings of this bird However, the most recent sighting was in 1992. The alleged sighting was reported to be in the southwest region of Paraguay near the city Corrientes. The bird was male.
Origin
The Glaucous Macaw is a bird native to South America. It is endangered. This magnificent bird has a distinctive blue feather pattern as well as a powerful beak that is capable of cracking open tough seeds and nuts. Glaucous Macaws live in monogamous pairs and both parents care for the chicks. They feed the chicks a diet of regurgitated food for the first few weeks after birth, and later they begin eating solid foods as they develop. Parents are also responsible for teaching the young macaws to fly and hunt.
The glaucous macaw is considered to be extinct in the wild, but stories of this gorgeous bird's existence persist throughout the world. It is believed that the glaucous macaw was extirpated in the 1800s because of logging and cattle grazing of yatay palm (Butia yatay) groves, where these birds typically gathered their food. It is believed that the glaucous macaw has made a comeback in captivity and is usually kept with its larger cousin Lear's macaw.
The glaucous Macaw is found in subtropical rainforests of South America. They are usually found in areas where there are many palm trees. They are also very adaptable to various types of forested environments. These beautiful birds are also known to be extremely territorial and will protect their feeding and nesting areas from intruders.
In the past, there have been a variety of reports about the glaucous Macaw However, they are generally regarded as unreliable. The most recent claim of a wild incident is an friend of Ridgely's that 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 last century has led many experts to think that it's likely extinct, however they have always been open to a remote possibility of its existence (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it does survive it is highly unlikely to reach huge numbers.
Habitat
The macaw glaucous is an impressive bird, renowned for its size and dazzling turquoise-blue coloration. The tail feathers and wings are long, which enhances its graceful and agile movement. This bird is an emblem of love and loyalty. Its beak, which is predominantly black, has a distinctive shape and allows it to crack nuts and seeds. These are a large portion of its diet.
IUCN has classified the Glaucous Macaw as Critically Endangered. It states that there is only a small population of this bird, and that it is at a risk of extinction. The species was previously relatively widespread, but it is found in northern Argentina, southern Paraguay and 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 small range, despite the fact that there were no reliable sightings after 1830. Specimens were collected until 1860 (in Corrientes). The last living Glaucous Macaw, believed to originate from Brazil was seen in the Buenos Aires Zoo back in 1936.
Re-evaluation of the historical documents suggests that this species was rather generalist in its preferences for habitat with a preference for savanna habitat intermingled with palm "islands" and areas of riparian forest along rivers. It was a specialised food source for palm fruits, especially those of the chatay or yatay palm (Butia yatay), but it could also consume ripe and unripe fruits, nuts, berries and vegetable matter. It nests on steep slopes, in cliffs and sometimes in tree cavities.
Like all parrots, this bird was social and probably gregarious. It could live up to 14.8 years in captivity and was said to be a reliable breeder, reproducing year after year. In the wild, its life expectancy was probably between 50 and 80 years. This species was a formidable seed disperser, and could 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 its environment. This massive South American parrot is known for its vibrant blue feathers, bright yellow eyes and the teardrop-shaped lappet on the lower part its beak.
Up until recently, very little was known about the feeding habits and diet of the Glaucous macaw. The earliest detailed references I have found are in two publications by H.W. Bates, "The Naturalist on the Amazons" first published in 1863, detailing his 11-year stay in Brazil and later in his book "As Birds of the Brazilian Forests". Both of these are about the Hyacinthine Macaw Anodorhynchus Aureolarius. I have no reason to believe that they don't apply 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 small quantities. 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 destruction of the yatay palm (Butia yatay) from which it may have gotten its majority of its diet.
In the wild, it was common to find the Glaucous macaw in subtropical forests and savannahs where palm trees were found. It hid in tree cavities, or on rocky banks or palm fronds. The female incubates and lays two eggs on average.
The young Glaucous Macaws are altricial, meaning they rely on their parents to care for them until they're fully grown and fly. Both females and males are extremely committed to their offspring and will tirelessly hunt for food and protect them from predators.
Unfortunately the Glaucous macaw is no longer present in the majority of its former habitat. The disappearance of this magnificent bird is likely to be due to continued trapping for the pet industry and disturbance to habitat, particularly the massive removal of palm yatays, which may have been its primary food source. The Glaucous Macaw is listed as Critically Endangered.
Breeding
Glaucous macaws are typically monogamous pairs with both parents taking a role in raising the young. They breed during the dry season, when food is most abundant. The female will lay up to three eggs, which are incubated by the mother for around 28 days. For the first few weeks following hatching, the chicks are fed by their parents through regurgitation. The young macaws then begin to explore their surroundings and learn how to eat themselves. They also learn how to fly and forage.
The glaucous Macaw can be described as a highly social bird. They are active during daylight hours, and take a break at night. During the night, they will often seek shelter inside tree cavities or other suitable nesting places. Their calls can be heard in the forest throughout the day.
The species is expected to rebound from the decline, however it is in danger of being wiped out by habitat loss and illegal trapping of the bird for the pet market, and deforestation. Only about 20 glaucous Macaws are believed to exist in the wild. The IUCN classifies the bird as "Critically Endangered - possibly Extinct."
The glaucous Macaw is sometimes referred to get more info as Lear's Macaw or Blue-throated Hummingbird, is distinguished by its vibrantly blue feathers. It is a large parrot with a length of 70 centimeters, and has a strong beak that is able to break open tough nuts and seeds. This beautiful bird is native South America and can be found in diverse habitats, including grasslands, lowland forests and wetlands.
This majestic bird is a symbol of South American biodiversity. Its appearance is elegant with its slim body, light weight and bright 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 it's often featured in bird shows. It is also popular in captivity where it can live for a long time.
