The glaucous macaw (Anodorhynchus glaucus) is a critically endangered or possibly extinct species of large, blue and grey South American parrot, a member of a large group of neotropical parrots known as macaws. This macaw is closely related to Lear's macaw (A. leari) and the hyacinth macaw (A. hyacinthinus). In Guaraní, it is called guaa-obi after its vocalizations.
The glaucous macaw is 70cm (28in) long. It is mostly pale turquoise-blue with a large, greyish head. The term glaucous describes its colouration. It has a long tail and a large bill. It has a yellow, bare eye ring and half moon-shaped lappets bordering the mandible.[3]
This bird was native to north Argentina, south Paraguay, the chaco and llano region of Bolivia near the city of Santa Cruz de la Sierra,[4] northeast Uruguay, and Brazil. It became rare during the 19th century due to trapping and loss of habitat, and only two possible reports of wild birds were received in the 20th century. Expeditions by ornithologists to southwestern Paraguay during the 1990s failed to turn up any evidence of the species. Furthermore, only the oldest residents of the region had knowledge of the macaw, with the species last recorded in the 1870s.[1] The bird's disappearance probably is linked to trapping of live adults for the wild bird trade and the wholesale felling of the yatay palm, Butia yatay, the nuts of which appear to have constituted its main food.[5] Although suitable habitat remains in El Palmar National Park, in the Argentine province of Entre Ríos, as well as southern Brazil, no rumours of the bird's continued existence in the past several decades have proven credible.[citation needed] A search conducted by Joe Cuddy and Tony Pittman in 1992 concluded that the birds were extinct in their former range.[6] Rumours persisted that blue macaws were seen in Argentina and Bolivia with a dealer in Rosario, Argentina, offering live specimens. The late George Smith gave many talks rich in conservation information on macaws, including this species, which he stated was not extinct in the wild, but existed in remote areas of Bolivia where he had encountered trappers who could identify this species. Moreover, he stated that stands of pure palm existed "as far as the eye could see" when he flew over the area which is yet to be investigated.[citation needed]
A 2018 study citing bird extinction patterns, the heavy destruction of its habitat, and the lack of any confirmed sightings since the 1980s recommended uplisting the species to Critically Endangered - Possibly Extinct.[7]
Macaws are a group of New World parrots that are long-tailed and often colorful, in the tribe Arini. They are popular in aviculture or as companion parrots, although there are conservation concerns about several species in the wild.
Conures are a diverse, loosely defined group of small to medium-sized parrots. They belong to several genera within a long-tailed group of the New World parrot subfamily Arinae. Most conures belong to the tribe Arini, though Myiopsitta is an exception. The term "conure" is used primarily in bird keeping, though it has appeared in some scientific journals. The American Ornithologists' Union uses the generic term parakeet for all species elsewhere called conure, though Joseph Forshaw, a prominent Australian ornithologist, uses conure.
Spix's macaw, also known as the little blue macaw, is a macaw species that was endemic to Brazil. It is a member of tribe Arini in the subfamily Arinae, part of the family Psittacidae. It was first described by German naturalist Georg Marcgrave, when he was working in the State of Pernambuco, Brazil in 1638 and it is named for German naturalist Johann Baptist von Spix, who collected a specimen in 1819 on the bank of the Rio São Francisco in northeast Bahia in Brazil. This bird has been completely extirpated from its natural range, and following a several-year survey, the IUCN officially declared it extinct in the wild in 2019. However, after over 20 years of conservation efforts, 200 macaws have been bred from just two parent birds, and 52 individual birds have since been reintroduced into their natural environment in June 2022.
Anodorhynchus is a genus of large blue macaws from open and semi-open habitats in central and eastern South America. It includes two extant species, the hyacinth macaw and Lear's macaw also known as the indigo macaw, and one probably extinct species, the glaucous macaw. At about 100 centimetres (39 in) in length the hyacinth macaw is the longest parrot in the world. Glaucous and Lear's macaws are exclusively cliff nesters; hyacinth macaws are mostly tree nesters. The three species mainly feed on the nuts from a few species of palms.
The scarlet macaw is a large yellow, red and blue Neotropical parrot native to humid evergreen forests of the Americas. Its range extends from southeastern Mexico to Peru, Ecuador, Colombia, Bolivia, Venezuela, Honduras, and Brazil in lowlands of 500 m (1,600 ft) up to 1,000 m (3,300 ft), the Caribbean island of Trinidad, as well as the Pacific island of Coiba. Formerly, the northern extent of its range included southern Tamaulipas. In some areas, it has suffered local extinction because of habitat destruction, or capture for the parrot trade, but in other areas, it remains fairly common. It is the national bird of Honduras. Like its relative the blue-and-yellow macaw, the scarlet macaw is a popular bird in aviculture as a result of its striking plumage. It is the third most common macaw species in captivity after the Blue and Gold and Greenwing Macaw respectively. In recent years it has become much rarer in captivity and much more expensive due to its placement on CITES Appendix I.
Lear's macaw, also known as the indigo macaw, is a large all-blue Brazilian parrot, a member of a large group of neotropical parrots known as macaws. It was first described by Charles Lucien Bonaparte in 1856. Lear's macaw is 70–75 cm long and weighs around 950 g. It is coloured almost completely blue, with a yellow patch of skin at the base of the heavy, black bill.
The blue-and-yellow macaw, also known as the blue-and-gold macaw, is a large Neotropical parrot with a mostly blue dorsum, light yellow/orange venter, and gradient hues of green on top of its head. It is a member of the large group of neotropical parrots known as macaws. It inhabits forest, woodland and savannah of tropical Central and South America, as well as the island of Trinidad in the Caribbean. They are popular in aviculture because of their striking color, ability to talk, ready availability in the marketplace, and close bonding to humans. It is the most commonly kept macaw species in captivity worldwide as a pet or companion parrot and is also the cheapest among the large macaws.
The hyacinth macaw, or hyacinthine macaw, is a parrot native to central and eastern South America. With a length of about one meter it is longer than any other species of parrot. It is the largest macaw and the largest flying parrot species; the flightless kākāpō of New Zealand outweighs it at up to 3.5 kg. While generally easily recognized, it could be confused with the smaller Lear's macaw. Habitat loss and the trapping of wild birds for the pet trade have taken a heavy toll on their population in the wild, so the species is classified as Vulnerable on the International Union for Conservation of Nature's Red List, and it is protected by its listing on Appendix I of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).
The blue-throated macaw, also known as the Caninde macaw or Wagler's macaw, is a macaw endemic to a small area of north-central Bolivia, known as Los Llanos de Moxos. In 2014 this species was designated by law as a natural patrimony of Bolivia. Until 2010, it was hunted by native people to make feathered "Moxeño" headdresses for "machetero" ritual dances.
The broad-billed parrot or raven parrot is a large extinct parrot in the family Psittaculidae. It was endemic to the Mascarene island of Mauritius. The species was first referred to as the "Indian raven" in Dutch ships' journals from 1598 onwards. Only a few brief contemporary descriptions and three depictions are known. It was first scientifically described from a subfossil mandible in 1866, but this was not linked to the old accounts until the rediscovery of a detailed 1601 sketch that matched both the subfossils and the accounts. It is unclear what other species it was most closely related to, but it has been classified as a member of the tribe Psittaculini, along with other Mascarene parrots. It had similarities with the Rodrigues parrot, and may have been closely related.
Ara is a Neotropical genus of macaws with eight extant species and at least two extinct species. The genus name was coined by French naturalist Bernard Germain de Lacépède in 1799. It gives its name to and is part of the Arini, or tribe of Neotropical parrots. The genus name Ara is derived from the Tupi word ará, an onomatopoeia of the sound a macaw makes.
The neotropical parrots or New World parrots comprise about 150 species in 32 genera found throughout South and Central America, Mexico, the Caribbean islands and the southern United States. Among them are some of the most familiar and iconic parrots, including the blue and gold macaw, sun conure, and yellow-headed amazon.
The Cuban macaw or Cuban red macaw is an extinct species of macaw native to the main island of Cuba and the nearby Isla de la Juventud. It became extinct in the late 19th century. Its relationship with other macaws in its genus was long uncertain, but it was thought to have been closely related to the scarlet macaw, which has some similarities in appearance. It may also have been closely related, or identical, to the hypothetical Jamaican red macaw. A 2018 DNA study found that it was the sister species of two red and two green species of extant macaws.
The blue-winged macaw, in aviculture more commonly known as Illiger's macaw, is a species of small macaw found in central and eastern South America. The second name is in honor of the German ornithologist Johann Karl Wilhelm Illiger. It was previously placed in the genera Ara or Propyrrhura. Blue-winged macaws have been known to reach an age of 50–60 years.
The Guadeloupe amazon or Guadeloupe parrot is a hypothetical extinct species of parrot that is thought to have been endemic to the Lesser Antillean island region of Guadeloupe. Mentioned and described by 17th- and 18th-century writers, it received a scientific name in 1789. It was moved to the genus Amazona in 1905, and is thought to have been related to, or possibly the same as, the extant imperial amazon. A tibiotarsus and an ulna bone from the island of Marie-Galante may belong to the Guadeloupe amazon. In 1905, a species of extinct violet macaw was also claimed to have lived on Guadeloupe, but in 2015, it was suggested to have been based on a description of the Guadeloupe amazon.
Glaucous is used to describe the pale grey or bluish-green appearance of the surfaces of some plants, as well as in the names of birds, such as the glaucous gull, glaucous-winged gull, glaucous macaw, and glaucous tanager.
The Martinique macaw or orange-bellied macaw is a hypothetical extinct species of macaw which may have been endemic to the Lesser Antillean island of Martinique, in the eastern Caribbean Sea. It was scientifically named by Walter Rothschild in 1905, based on a 1630s description of "blue and orange-yellow" macaws by Jacques Bouton. No other evidence of its existence is known, but it may have been identified in contemporary artwork. Some writers have suggested that the birds observed were actually blue-and-yellow macaws. The "red-tailed blue-and-yellow macaw", another species named by Rothschild in 1907 based on a 1658 account, is thought to be identical to the Martinique macaw, if either one ever existed.
Butia paraguayensis is a species of Butia palm tree found in the cerrado region of South America. Its natural range runs from Mato Grosso do Sul and São Paulo in southern Brazil through Paraguay to northern Argentina and Uruguay. It was given the name dwarf yatay palm in English by 2000, and it is locally known as yata'i in Guaraní in Paraguay, or butiá-do-cerrado in Portuguese in Rio Grande do Sul, Brazil.
Butia yatay, the jelly palm or yatay palm, is a Butia palm native to southern Brazil, Uruguay and northern Argentina. It is known as the butiá-jataí in Portuguese in the south of Brazil, as well as simply jataí or butiá. It is sometimes cultivated as an ornamental in Europe and the United States. It is the tallest of all the species in the genus Butia. The fruit is edible with a sweet flavour.
