Anodorhynchus glaucus is a chordate, or more specifically a bird, in the Psittacidae family.

Anodorhynchus glaucus is commonly known (its common name) as the Glaucous Macaw in English. In French (Français), Anodorhynchus glaucus is commonly known as the Ara Bleu or Ara Glauque. In Spanish (Español), Anodorhynchus glaucus is commonly known as the Ara Azul or Guacamayo Glauco or Guacamayo Violáceo.

Anodorhynchus glaucus is classified as critically endangered by the IUCN Red List of Threatened Species, the world's most comprehensive inventory of the global conservation status of plant and animal species maintained by the International Union for Conservation of Nature and Natural Resources. Anodorhynchus glaucus's population trend was unknown at last assessment.

Species Authority: The species authority, or the name(s) of scientist(s) or person(s) who first described Anodorhynchus glaucus is (Vieillot, 1816) (IUCN Red List).

Summary: [an error occurred while processing this directive] (Wikipedia).

Country Distribution: Anodorhynchus glaucus is found in the following countries:

Argentina, Brazil, Paraguay, Uruguay (IUCN Red List).

Biome(s)/Ecosystem(s): IUCN lists the following as biomes for Anodorhynchus glaucus: Terrestrial (IUCN Red List).

Major Habitat(s): 1.6 Forest - Subtropical/Tropical Moist
2.1 Savanna - Dry (IUCN Red List).

Range: Anodorhychus glaucus was formerly widespread but clearly very local in north Argentina, south Paraguay, north-east Uruguay and Brazil from Paran state southwards. It was endemic to the middle reaches of the major rivers (Uruguay, Paran and Paraguay) and adjacent areas, with most records coming from Corrientes, Argentina. It became rare before or early in the second half of the 19th century and there were only two acceptable records in the 20th century, one direct observation (in Uruguay in 1951) and one based on local reports (in Paran in the early 1960s). A recent, thorough survey of Corrientes Province (Argentina) and Rio Grande do Sul (Brazil) examining suitable palm groves and nesting/roosting cliffs found no evidence of its presence and concluded that it had become extinct in the first half of the 20th century². Whilst it has been generally treated as extinct, persistent rumours of recent sightings, local reports and birds in trade indicate that a few birds may still survive. (IUCN Red List).

CONSERVATION STATUS

Red List Category & Criteria: Anodorhynchus glaucus is listed as CR D ver 3.1 (2001) (IUCN Red List).

Year Assessed: Anodorhynchus glaucus's status was assessed in 2004 (IUCN Red List).

Assessor: Anodorhynchus glaucus's Red List status was evaluated by BirdLife International (IUCN Red List).

Red List Evaluator: The Red List Evaluator for Anodorhynchus glaucus is listed by IUCN as Clay, R. (Guyra Paraguay: Conservacin de Aves), Capper, D. & Wege, D. (BirdLife International Red List Authority) (IUCN Red List).

Red List Rational / Justification : Anodorhynchus glaucus is listed by IUCN for the following: This species was last recorded in the 1960s and it is likely to have declined severely as result of hunting and trapping, plus habitat degradation and destruction. However, it may well remain extant, because not all of its formerly large range has been adequately surveyed, and there have been persistent and convincing local reports. Any remaining population is likely to be tiny, and for these reasons it is treated as Critically Endangered. (IUCN Red List).

Threats: 1.1.3 (Wikipedia).

Red List History: Anodorhynchus glaucus was listed on the IUCN Red List of Threatened Species in 1988 (IUCN Red List).
