Glaucous Macaw
The glaucous macaw is one of the rarest birds in the world. It is considered Critically Endangered, and may be extinct in the wild.
The bird has been observed by aviculturists from various countries, but the latest sighting was reported 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 parrot native to South America. It is threatened. This majestic bird is distinguished by its distinctive blue feather pattern as well as a powerful beak that is capable of cracking open tough seeds and nuts. Glaucous macaws are known to form long-term monogamous couples and both parents assist in raising the chicks. They feed the chicks regurgitated food for the first few weeks after birth, and later they begin to eat solid foods as they grow. Parents also play a crucial role in teaching young macaws to fly and forage.
The glaucous Macaw has gone extinct, but rumors about its existence continue to spread across the globe. 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. The Glaucous Macaw is believed be making a comeback and is often kept along with its larger mate, 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 found in areas with many palm trees. They are also very adaptable to various types of forest habitats. These beautiful birds are also known to be extremely territorial and will defend their feeding and nesting areas from intruders.
There have been a number of reports on the glaucous macaw throughout the years, but most are considered to be unreliable. The most recent wild claim was made by an avicultural friend of Ridgely who claimed to have seen four Glaucous Macaws in Califomia. This is a completely absurd claim until it is confirmed with hard evidence. The absence of any credible evidence of this bird in the last century has caused many experts to conclude that it is likely extinct, but they have always accepted a remote possibility of its survival (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it survives it is highly unlikely to reach large numbers.
Habitat
The Glaucous Macaw is a magnificent bird, renowned for its size and turquoise-blue coloring. The tail and wings are long, enhancing its graceful and agile movement. The bird is an emblem of loyalty and love. Its beak is mostly black, and it has a unique shape that allows it to open seeds and nuts, which make up a large portion of its diet.
IUCN has classified the Glaucous Macaw as Critically Endangered. It says that there is only a small population of the bird and it is in risk of extinction. This species was formerly quite widespread, but today it is only 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 credible sightings of the species since 1830 however, the Glaucous Macaw seemed not to be a rare species in its limited range. specimens were captured until 1860 (in Corrientes). The last living Glaucous Macaw, believed to originate from Brazil was seen in the Buenos Aires Zoo back in 1936.
The reassessment suggests that the species is a generalist, and prefers savanna habitat that is interspersed with palm "islands" and bands of riparian forests along river systems. It was a particular eater of palm fruits, particularly those of the chatay or yatay palm (Butia yatay) however, it could also feed on ripe and unripe fruits, nuts, berries and vegetables. It nests on steep slopes on cliffs, in cliffs, and occasionally in tree cavities.
This bird was likely to be gregarious and social, just like other parrots. It was able to live up to 14.8 years in captivity and was believed to be a dependable breeder, reproducing year after year. Its life expectancy in the wild was about 50 to 80 years. This species was a powerful disperser of seeds and may have contributed to 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 an immense impact in its environment. This massive South American bird is known for its vibrant blue feathers and yellow eyes and also for its distinctive teardrop-shaped lappet which adorns the lower portion where to get a macaw of its beak.
Up until recently, very little was known about the 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 about his 11 year sojourn in Brazil and later in his work "As Birds of the Brazilian Forests". Both of these references to the Hyacinthine Macaw (Anodorhynchus aureolarius) However, I have no reason to believe that they are not applicable to this species.
It is likely that the Glaucous Macaw was a particular for the consumption of palm nuts. It also ate other seeds, fruits and vegetable matter in smaller quantities. The diet of this species is likely to have been influenced by the clearance of forests by the 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 the Glaucous Macaw was commonly found in subtropical forests with the savannahs and cliffs surrounded by palm trees, where it nestled in tree cavities, on rocky banks or in the top of palm fronds. On average two clutches of eggs was laid and incubated by the female.
The young Glaucous Macaws are altricial, meaning they depend on their parents to look after them until they become fully fledged and can fly. Both the males and females are very dedicated to their offspring, and will hunt for food and protect them from predators.
Unfortunately, the Glaucous macaw has been present in the majority of its former habitat. The disappearance of this majestic bird is probably due to the continued trapping for the pet trade and disturbance to habitat, specifically the mass clearing of yatay palms from which it may have obtained its primary food source. The Glaucous Macaw is classified as Critically Endangered.
Breeding
Glaucous Macaws are monogamous, long-term pair. Both parents are involved in raising their children. They breed during the dry season when food availability is at its highest. The female lays a clutch of two to three eggs, which are incubated for a period of around 28 days. For the first few weeks after hatching the chicks are fed by their parents through regurgitation. Macaws are then able to explore and learn to feed themselves. They also learn to fly and hunt for food.
The glaucous Macaw is a very social bird. They are active during the day but are restful at night. They will often seek shelter in cavities in trees or other suitable nesting sites for the night. They are highly vocal, and their calls can be heard throughout the forest during the day.
The species is expected to recover from the decline, but it is facing numerous threats, including habitat loss, illegal trapping of the bird for pet trade, and deforestation. It is believed that there are just 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 can be distinguished by its vivid blue feathers. The parrot is 70 centimeters in length and has a powerful beaks that are capable of cracking open nuts and seeds. This beautiful bird is native South America and can be found in various habitats such as grasslands, lowland forests and wetlands.
This majestic bird is an emblem of South American biodiversity. Its appearance is elegant with its slender body, vibrant blue feathers, and lightweight build. The beak is curved and black, which helps it crack open the seeds and nuts which comprise a significant portion of its diet. It is a stunning bird that is often seen in bird shows. It is also popular in captivity where it can live for a lifetime.
