Glaucous Macaw
The glaucous macaw is one of the rarest birds on earth. It is critically endangered and could even be extinct.
Many aviculturalists have reported sightings of this bird, but the most recent was in 1992. This alleged sighting occurred in the southwestern region of Paraguay, near the city of Corrientes. The bird was male.
Origin
The Glaucous macaw is a threatened parrot species native to South America. This magnificent bird is characterized by a blue feather pattern, and a strong beak that can break open nuts and seeds. Glaucous Macaws live in monogamous couples and both parents tend the chicks. The chicks are fed a diet of regurgitated food in the first few weeks of their lives and then a variety of solid foods as they grow. Parents also are a key part of teaching young macaws to fly and hunt.
The glaucous macaw is considered to be extinct in the wild, however rumors of this beautiful bird's existence are still spreading across the globe. It is estimated 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 typically gathered their food. The glaucous Macaw is believed to be making a comeback and is often kept along with its larger cousin, Lear's macaw.
The glaucous Macaw can be found in subtropical rainforests of South America. They are most often found in areas with numerous palm trees. They are also known to be extremely adaptable to different types of forest habitats. These beautiful birds can be territorial and will defend the nesting and feeding areas from intruders.
In the past, there have been numerous reports of the glaucous macaw However, they are generally considered unreliable. The most recent claim of a wild event is a friend of Ridgely's who claimed to have observed four Glaucous macaws in Califomia. This claim is unacceptable until it can backed up with evidence. The absence of any reliable data on this bird over the last century has caused many experts to think that it's likely extinct, yet they have always been open to the possibility of survival (Vielliard 1979, Ridgely 1981a, Sick 1985, Chebez 1986a). If it does survive it will be very uncommon to observe large numbers.
Habitat
The Glaucous Macaw is a magnificent bird, known for its huge size and turquoise-blue coloring. Its long tail and wings accentuate its graceful and agile movements. This bird is a symbol of loyalty and love. Its beak is primarily black and has a distinctive shape that allows it to crack 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 a very small population of the bird, and that it is at a high-risk of extinction. This species was formerly relatively widespread, but it is only found in northern Argentina and southern Paraguay and north-eastern Uruguay and Brazil from Parana state southwards where it nestted in cliffs along 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 1860 (in Corrientes). The last known living Glaucous Macaw was seen at the Buenos Aires Zoo in 1936 and is believed to have come from Brazil.
Reassessment suggests that this species is a generalist, preferring areas of savanna that are which is surrounded by palm "islands" and bands of riparian forests along rivers. It was a specific eater of palm fruits, particularly those of the chatay palm (Butia yatay) however, it could also feed on ripe and unripe fruits such as berries, nuts, and vegetable matter. It nests on slopes that are steep on cliffs, in cliffs, and occasionally in tree cavities.
This bird was likely gregarious and social, like other parrots. It was believed that it could live 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 powerful seed disperser, and could have contributed to read more the success of the yatay palm in its native habitats.
Feeding
The Glaucous Macaw (Anodorhynchus glaucus) is one of the most magnificent of all the species of parrots and its presence has an enormous impact on its environment. This huge South American bird is known for its vivid blue feathers and yellow eyes as well as the distinctive teardrop-shaped lappet that brackets the lower portion of its beak.
Up until recently, very little was known about the feeding habits and diet of the Glaucous macaw. The first detailed references I have located are two works by H.W. Bates' "The Naturalist on the amazons", first published in 1863, describes his 11-year journey in Brazil. In his later book "As Birds of the Brazilian Forests" Bates wrote about the same experience. Both of these references to the Hyacinthine Macaw (Anodorhynchus aureolarius) however I see no reason to believe that they're not applicable to this species.
The Glaucous macaw is likely have been a specialist eater, consuming only palm nuts as well as small amounts of other seeds, fruits and other matter. This species' diet was likely affected by the clearing of forests to cultivate cattle and the cattle-ranching practices of early colonists, and the removal of yatay (Butia) palms from which it got a large portion of its nutritional value.
In the wild, the Glaucous Macaw was often found in subtropical forests with mountains and savannahs that were surrounded by palm trees where it nested in tree cavities, on rocky banks, or in the top of palm fronds. Females incubate and lay two eggs per.
The young Glaucous Macaws are altricial, which means they depend on their parents to care for them until they are fully fledged and can fly. Both males and females are very dedicated to their offspring, and hunt for food and protect them against predators.
Unfortunately the Glaucous Macaw has been eradicated from most of its previous range. The disappearance of the magnificent bird is likely to be due to trapping that continues for the pet industry, as well as disturbance to habitat, particularly the wholesale removal of palm yatays that may have been its primary food source. The Glaucous Macaw is listed as Critically Endangered.
Breeding
Glaucous macaws usually form long-term monogamous couples and both parents play part in raising the young. They breed in the dry season, when the food supply is at its highest. Females lay a clutch of two to three eggs that are incubated for about 28 days. In the initial few weeks after hatching, the chicks are fed by their parents via regurgitation. Macaws are then able to explore and learn to feed themselves. They are also taught to fly and hunt for food.
The glaucous Macaw is a extremely social bird. They are active during daylight hours, and rest at night. During the night they usually seek refuge inside tree cavities or other nesting areas that are suitable. Their calls can be heard throughout the forest throughout the day.
The species is expected to rebound from the decline, but it is facing numerous threats, including habitat loss and illegal trapping of the bird for the pet market, and deforestation. There are only about 20 glaucous Macaws that are believed to be in the wild. The IUCN has classified the bird as "Critically endangered--possibly extinct."
The glaucous macaw, sometimes referred to as Lear's Macaw or blue-throated Hummingbird is distinguished by its bright blue feathers. It is a large bird, measuring 70 centimeters in length and features a robust beak that can crack open hard nuts and seeds. This beautiful bird is native to South America, and it is found in a variety of habitats such as forests, dry lowland grasslands and wetland.
This majestic bird is a symbol of South American biodiversity. It has a regal appearance, with its slender build, lightweight body and bright blue feathers. The black and curly beak allows it to break open seeds and nuts which are a large part of its diet. It is a beautiful bird and is often used in bird shows. It is also a popular bird in captivity, where it could be kept for a lifetime.
