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 from various countries, but the latest sighting was reported in 1992. This alleged sighting occurred in the southwestern region of Paraguay close to the city of Corrientes. The bird was male.
Origin
The Glaucous macaw is a threatened parrot species that is native to South America. This magnificent bird is characterized by blue feathers, and a powerful beak that can break open nuts and seeds. Glaucous Macaws live in monogamous pair, and both parents raise the chicks. The chicks are fed regular food in the first few weeks of their lives before being fed solid food as the chicks grow. Parents play a crucial role in teaching the young macaws how to fly and hunt.
The glaucous Macaw is extinct, but rumors about its existence persist all over the world. It is believed that the glaucous macaw was extinct in the 1800s due to the logging industry and cattle grazing in yatay palm (Butia yatay) trees, where these birds primarily gathered their meals. The glaucous Macaw is believed to have made a comeback, and is usually kept with its larger mate, Lear's macaw.
In terms of habitat the glaucous macaw can be found in sub-tropical forests of South America. They are most often found in areas where there are numerous palm trees. They are also highly adaptable to a variety of forest habitats. These beautiful birds are also known to be very territorial and will protect their nesting and feeding areas from intruders.
There have been a variety of reports involving the glaucous macaw through the years, but they are considered to be unreliable. The most recent wild claim was made by an avicultural acquaintance of Ridgely who claimed to have spotted four Glaucous Macaws in Califomia. This is completely untrue until it is verified by hard evidence. The absence of any reliable evidence of this bird in the last century has led many experts to conclude that it is likely extinct, yet they have always been open to the possibility of existence (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it is able to survive, it will be extremely rare to observe large numbers.
Habitat
The glaucous macaw is a striking bird, renowned for its size and striking turquoise-blue coloring. The tail and wings are long, enhancing its graceful and agile movement. This bird is a symbol of loyalty and love. Its beak is mostly black and has a distinctive shape that allows it to crack open nuts and seeds, which comprise a large portion of its diet.
The Glaucous Macaw is considered Critically Endangered by the IUCN and the IUCN states that it has an extremely small population and is at a high danger of disappearing. This species was formerly quite widespread, but today it is found only 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 The Glaucous Macaw seemed not to be a rare species in its limited range. specimens were collected from 1830 to 1850 (in Corrientes). The last living Glaucous Macaw, believed to be from Brazil was seen in the Buenos Aires Zoo back in 1936.
Reassessment suggests that this species is a generalist, preferring savanna habitat that is interspersed with palm "islands" and riparian forests along rivers. It was a particular in the consuming of palm fruit especially those of the yatay (or chatay) palm (Butia). However it also ate ripe and unripe fruits as well as berries, nuts and vegetable matter. It is a nesting place on steep slopes, in cliffs and sometimes in tree cavities.
Like all parrots, this bird was social, and was likely to be gregarious. It was believed that it could live to 14.4 years in captivity and was a reliable breeder who reproduced year after year. The life expectancy of this species in the wild was about 50 to 80 years. This species was a potent disperser of seeds and could have contributed to the success of the palm yatay in its natural habitat.
Feeding
The Glaucous Macaw (Anodorhynchus glaucus) is among the most magnificent of all the species of parrots, and its presence commands 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 portion of its beak.
Until recently very little was known about diet of the Glaucous Macaw. The earliest detailed references I have discovered are in two books by H.W. Bates, "The Naturalist on the Amazons" first published in 1863 on his 11 year stay in Brazil and later in his work "As Birds of the Brazilian Forests". Both of these refer to the Hyacinthine Macaw (Anodorhynchus aureolarius) However, I have no reason to think that they are not applicable to this species.
It is probable that the Glaucous Macaw was a specialized for the consumption of palm nuts. It also consumed other seeds, fruits, and vegetable matter in small amounts. The diet of this species is likely to be affected by the clearing 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 a lot of its food.
In the wild, the Glaucous Macaw was commonly found in subtropical forests that had mountains and savannahs that were surrounded by palm trees, where it nestled in tree cavities and on rocky banks or in the palm fronds' top. On average two clutches of here eggs was laid and incubated by the female.
The young Glaucous Macaws are altricial, which means they depend on their parents to take care of them until they're fully grown and fly. Both females and males are extremely committed to their offspring and tirelessly hunt for food and defend them from predators.
Unfortunately the Glaucous macaw has been found in its former habitat. The disappearance of this majestic bird is probably due to the continued trapping of pets for the pet trade, as well as disturbance to habitat, specifically the massive clearing of yatay palms from which it could have gotten its primary food source. The Glaucous Macaw is listed as Critically Endangered.
Breeding
Glaucous Macaws are monogamous, long-term pairs. Both parents are involved in the raising of their children. They breed in the dry season, when food is most abundant. The female will lay two to three eggs which are incubated by the mother for about 28 days. In the initial few weeks after hatching, the chicks are fed by their parents via regurgitation. Macaws are then able exploring and learning to feed themselves. They also learn to fly and forage.
The glaucous Macaw is very social bird. They are active during daylight hours and rest at night. In the evening they often seek refuge in tree cavities or other nesting spots that are suitable. Their calls can be heard throughout the forest throughout the day.
While it is believed that the species will recover from its decline in the wild, the bird is facing numerous threats, including the loss of habitat, illegal trapping for the pet trade, and deforestation. It is believed that there are just 20 glaucous macaws that are in the wild. The IUCN has classified the bird as "Critically endangered--possibly extinct."
The glaucous macaw, also known as Lear's Macaw, or the blue-throated Hummingbird is distinguished by its vibrantly blue feathers. The parrot measures 70 centimeters in length and has a a powerful beak capable of slicing 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 magnificent bird is a symbol of South American biodiversity. Its elegant appearance, with its slender body, light build and bright blue feathers. The beak is curved and black, which aids it open the nuts and seeds which comprise a significant portion of its diet. It's a beautiful bird, and it's often used in shows featuring birds. It is also a popular bird in captivity, where it can be kept for a lifetime.
