Glaucous Macaw
The glaucous Macaw is among the rarest birds in the world. It is Critically Endangered, and may be extinct in the wild.
The bird has been observed by aviculturists across the globe However, the most recent sighting was reported 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 an endangered parrot species that is native South America. This magnificent bird is characterized by a blue feather pattern, and a strong beak capable of cracking open nuts and seeds. Glaucous Macaws are monogamous pairs and both parents care for the chicks. They feed the chicks regurgitated food for the first couple of weeks after birth, before they begin eating solid foods as they develop. Parents are a key part of teaching young macaws to fly and forage.
The glaucous Macaw is thought to be extinct in the wild, yet rumors of this beautiful bird's existence continue to spread all over the world. It is estimated that the glaucous Macaw was extirpated in the 1800s due to the logging industry and cattle grazing in yatay palm (Butia yatay) groves, where these birds typically gathered their food. The Glaucous Macaw is believed have returned, and is often kept along 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 most often located in areas where there are numerous palm trees. They are also extremely adaptable to different types of forested environments. These beautiful birds are also known to be extremely territorial and will protect their nesting and feeding areas from invaders.
Over the years there have been a variety of reports of the glaucous macaw however they are generally regarded as unreliable. The most recent claim of a wild incident is an avicultural acquaintance of Ridgely's who claimed to have witnessed four Glaucous macaws in Califomia. This claim is completely unacceptable until it is confirmed by hard evidence. The absence of any reliable data on this bird over the past century has led many experts to believe that it is extinct, but they have always accepted a remote possibility of its survival (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it does survive it is highly unlikely to be seen in large numbers.
Habitat
The macaw glaucous is an impressive bird that is renowned for its large size and stunning turquoise-blue coloring. The tail feathers and wings are long, enhancing its graceful and agile moves. It is also a symbol of loyalty and love. Its beak, which is primarily black, has a distinct shape and allows it to crack nuts and seeds. These are a large part of its diet.
IUCN has classified the Glaucous Macaw as Critically Endangered. It says that there is a tiny population of this bird and it is in risk of extinction. The species was once relatively widespread, but it is found in northern Argentina and southern Paraguay and north-eastern Uruguay and Brazil from Parana state southwards, where it was a nesting place in cliffs along major rivers.
Although there haven't been any confirmed sightings of this species since 1830 however, the Glaucous Macaw seemed not to be a rare species in its limited range. specimens were collected until 1860 (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 and prefers savanna habitat interspersed with palm "islands" and bands of riparian forests along river systems. It was a specific food source for palm fruits, especially those of the chatay or yatay palm (Butia yatay) however, it was also likely to consume unripe and ripe fruits such as berries, nuts, and vegetables. It nestled on slopes and in cliffs occasionally in tree cavities and laid an average clutch of two eggs.
This bird was likely to be gregarious and social, just like other parrots. It was said that it could live for up to 14.4 years in captivity, and was a reliable breeder that reproduced year after. In the wild, its lifespan was probably between 50 and 80 years. This species was a potent disperser of seeds and may have contributed to the success of the palm yatay in hahns macaw for sale its natural habitats.
Feeding
The Glaucous Macaw (Anodorhynchus glaucus) is among the most magnificent of all the species of parrots and its presence has an immense impact in its surroundings. This large South American bird is known for its vibrant blue feathers and eyes that are yellow, as well as the distinctive teardrop-shaped lappet that brackets the lower part of its beak.
Up until recently, very little was known about the eating habits and diet of the Glaucous macaw. The earliest detailed references I have found are in two works by H.W. Bates' "The Naturalist on the amazons" which was first published in 1863, and describes his 11-year sojourn in Brazil. In his later book "As Birds of the Brazilian Forests", he wrote about the same experience. Both are about the Hyacinthine Macaw Anodorhynchus Aureolarius. There is no reason to believe that they do not apply to this species.
It is likely that the Glaucous Macaw was a specialist for the consumption of palm nuts. It 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 the early colonists to cultivate and cattle ranching, as well as the felling of the yatay palm (Butia yatay) from which it may have gotten its majority of its diet.
In the wild, the Glaucous Macaw was found in subtropical forests with the savannahs and cliffs surrounded by palm trees, where it nested in tree cavities, on rocky banks or the palm fronds' top. On average two clutches of eggs was laid and incubated by the female.
The young Glaucous Macaws are altricial, meaning they rely on their parents to look after them until they are fully fledged and can fly. Both the males and females are very dedicated to their offspring, and hunt for food and protect them from predators.
Unfortunately, the Glaucous macaw isn't present in the majority of its former habitat. The disappearance of this magnificent bird is likely due to trapping that continues for the pet industry, as well as habitat disruption, especially the massive removal of palm yatays that could have been their primary food source. The Glaucous macaw is classified as Critically Endangered.
Breeding
Glaucous macaws usually form long-term monogamous couples, with both parents playing a role in raising the young. They breed in the dry season when food availability is at its highest. The female lays an egg clutch that ranges from two to three eggs that are incubated for about 28 days. After hatching, they are fed by their parents via regurgitation for the first few weeks of their life. The young macaws then begin to explore and learn to feed themselves. They also learn how to fly and hunt for food.
The glaucous Macaw is a extremely social bird. They are active during daylight hours, and rest during the night. They will often seek shelter in tree cavities or other suitable nesting sites to sleep. Their calls can be heard in the forest throughout the day.
The species is expected to rebound from the decline, however it faces many threats including habitat loss, illegal trapping of the bird to sell on the pet market and deforestation. Only about 20 glaucous Macaws are believed to exist in the wild. The IUCN has classified the bird as "Critically endangered, possibly extinct."
The glaucous macaw, also known as Lear's Macaw or blue-throated Hummingbird is distinguished by its vibrantly blue feathers. The parrot is 70 centimeters long and features a a powerful beak capable of cracking open nuts and seeds. This gorgeous bird is native to South America, and it can be found in many habitats like grasslands, forests, dry lowland, and wetland.
This majestic bird is a symbol of South American biodiversity. It has a regal look with its slim body, vibrant blue feathers and its light build. The beak is curved and black, which helps it crack open the seeds and nuts that make up a major portion of its diet. It is a beautiful bird that is often seen in bird shows. It is also popular in captivity, where it can live for a lifetime.
