Glaucous Macaw
The glaucous macaw is one of the rarest birds on earth. It is in danger of disappearing and could even be extinct.
Many birdwatchers have reported sightings this bird, but the most recent was in 1992. This alleged sighting occurred in southwestern Paraguay close to the city of Corrientes. The bird was male.
Origin
The Glaucous Macaw is a bird native to South America. It is threatened. This majestic bird is distinguished by the blue feather pattern and a sharp beak that is capable of breaking open seeds and nuts. Glaucous Macaws are monogamous couples and both parents tend the chicks. They feed the chicks regurgitated food for the first few weeks after birth, before they begin eating solid food as they grow. Parents are also responsible for teaching young macaws to fly and hunt.
The glaucous Macaw is extinct, yet rumors of its existence continue to spread all over the world. The glaucous Macaw is believed to have gone extinct in the 1800s due to cattle grazing on yatay (Butia) palm groves from which the birds would gather their food. It is believed that the glaucous macaw returned to captivity and is usually kept alongside its larger cousin Lear's macaw.
The glaucous Macaw lives in subtropical rainforests of South America. They are most often located in areas with numerous palm trees. They are also highly adaptable to a variety of forest environments. These beautiful birds are territorial and will protect the feeding and nesting area from intruders.
There have been a number of reports about the glaucous macaw over the years, but they are considered to be unreliable. The most recent report of a wild event is a friend of Ridgely's that claimed to have seen four Glaucous macaws in Califomia. This is completely untrue until it is confirmed by hard evidence. The lack of any acceptable records of this bird in the last century has led many experts to think that it's likely extinct, yet they have always been open to the possibility of existence (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it survives, it is extremely unlikely to make it to huge numbers.
Habitat
The macaw with the glaucous is a striking bird, renowned for its large size and dazzling turquoise-blue coloration. The tail feathers and wings are long, which enhances its fluid and graceful movements. This bird is also a symbol of loyalty and love. Its beak is predominantly black, and it is distinctive in its shape. It allows it to break open seeds and nuts which constitute a significant portion of its diet.
IUCN has classified the Glaucous Macaw as Critically Endangered. It states that there is a small population of this bird and it is in high-risk of extinction. The species was once widespread, but is now only found in northern Argentina south Paraguay and north-eastern Uruguay, as well as Brazil and Brazil from Parana state to south, where it is nestled in cliffs alongside major rivers.
Although there have been no confirmed sightings of this species since 1830, the Glaucous Macaw seemed not to be a rare species in its relatively limited range; specimens were collected until 1850 (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, preferring the savanna habitat, which is which is surrounded by palm "islands", and riparian forests along rivers. It was a specific eater of palm fruits, particularly those of the yatay or chatay palm (Butia yatay) but it was likely to also feed on ripe and unripe fruits such as berries, nuts, and vegetables. It nestled on steep slopes and in 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 for get more info up to 14.8 years in captivity and was believed to be a reliable breeder that reproduced year after year. The lifespan of the species in the wild was between 50 and 80 years. The species was a strong disperser of seeds and may be a factor in the success of the palm yatay species in its natural habitat.
Feeding
The Glaucous Macaw (Anodorhynchus glaucus) is among the most beautiful of the species of parrots and has a a powerful impact in its environment. This huge South American bird is known for its vivid blue feathers and eyes that are yellow, as well as the distinctive teardrop-shaped lappet that brackets the lower portion of its beak.
Up until recently, very little was known about feeding habits of the Glaucous Macaw. The earliest detailed references that I have come across are two works by H.W. Bates, "The Naturalist on the Amazons" first published in 1863, detailing his 11-year stay in Brazil and later in his work "As Birds of the Brazilian Forests". Both are about the Hyacinthine Macaw, Anodorhynchus Aureolarius. There is no reason to think that they could not apply to this species.
It is probable that the Glaucous Macaw was a particular for the consumption of palm nuts. It also took other seeds, fruits, and vegetable matter in small amounts. The diet of this species is likely to have been influenced by the clearance of forests by the early colonists to cultivate and cattle ranching as well as the felling of the yatay palm (Butia yatay) from which it could have gotten its majority of its food.
In the wild in the wild, the Glaucous Macaw was often found in subtropical forests with cliffs and savannahs with palm trees where it nested in tree cavities and on rocky banks, or in the palm fronds' top. The female incubates and lays two eggs per.
The young Glaucous Macaws are altricial, which means they depend on their parents to care for them until they become fully grown and able to fly. Both females and males are extremely dedicated to their offspring and will constantly hunt for food and defend them from predators.
Unfortunately, the Glaucous Macaw has been eradicated from the majority of its previous range. The disappearance of this majestic bird is most likely due to the ongoing trapping of pets for the pet trade as well as disturbance to habitat, specifically the massive removal of yatay palms which it could have gotten its main food supply. The Glaucous Macaw is listed as Critically Endangered.
Breeding
Glaucous macaws are typically monogamous pairs and both parents play an active role in the raising of the young. They breed in the dry season, when food is most abundant. Females lay up to three eggs, which are incubated by the mother for about 28 days. Once the chicks hatch, they are fed by their parents through regurgitation for the first couple of weeks of their life. The macaws' young begin to explore their surroundings and learn how to eat themselves. They also learn to fly and forage.
The glaucous Macaw can be described as a very social bird. They are active during daylight hours and take a break at night. During the night, they will often seek refuge in tree cavities or other suitable nesting places. They are highly vocal, and their calls can be heard throughout the forest during the day.
The species is expected to recover from its decline, however it is facing numerous threats, including habitat loss, illegal trapping of the bird for pet trade, 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 as Lear's Macaw, or the blue-throated Hummingbird, is distinguished by its bright blue feathers. It is a large parrot, with a length of 70 centimeters and features a robust beak that is able to break open tough nuts and seeds. This gorgeous bird is native to South America and can be found in diverse habitats such as grasslands, lowland forests and wetlands.
This magnificent bird is a symbol of South American biodiversity. Its elegant appearance with its slim build, lightweight body and bright blue feathers. The beak is curved and black, which aids it crack open the nuts and seeds that make up a major portion of its diet. It is a stunning bird and is often used in birds shows. It is also a popular bird in captivity, where it can remain for a long time.
