Amazona pretrei is a chordate, or more specifically a bird, in the Psittacidae family.

Amazona pretrei is commonly known (its common name) as the Red-Spectacled Amazon in English. In French (Français), Amazona pretrei is commonly known as the Amazone De Prêtre. In Spanish (Español), Amazona pretrei is commonly known as the Amazona Cabecirroja or Amazona Charao or Loro Cabecirrojo or Loro De Cabeza Roja.

Amazona pretrei is classified as vulnerable 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. Amazona pretrei's population trend was decreasing at last assessment, meaning its numbers are declining in the wild.

Species Authority: The species authority, or the name(s) of scientist(s) or person(s) who first described Amazona pretrei is (Temminck, 1830) (IUCN Red List).

Country Distribution: Amazona pretrei is found in the following countries:

Argentina, Brazil, Paraguay (IUCN Red List).

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

Major Habitat(s): 1.5 Forest - Subtropical/Tropical Dry
1.6 Forest - Subtropical/Tropical Moist
1.9 Forest - Subtropical/Tropical Moist Montane
2.1 Savanna - Dry
11.3 Artificial/Terrestrial - Plantations (IUCN Red List).

Range: Amazona pretrei breeds in Rio Grande do Sul, south Brazil, with main populations in the Campo de Cima da Serra, Planalto Mdio, Depresso Central, Serra do Sudeste and Alto Uruguai⁴. Southern (and perhaps northern) breeders move north in the austral winter. Most of the wintering population formerly roosted at Aracuri but, since 1991, there has been a shift to south-east Santa Catarina⁵. In 1994, there were 15 roost sites in use seasonally, but large roosts at Aracuri and Rinco dos Pereira had disappeared. There has been a startling population decline since the 1950s. In 1971, the Aracuri roost was c.30,000 individuals, but more recent estimates of the total population are 7,500-8,500 individuals in the early 1990s, c.10,000 in 1994, c.12,600 in 1996 and c.16,300 in 1997⁵. Elsewhere, there is an erroneous 19th century specimen from So Paulo⁷. Wandering birds occur in Argentina and Paraguay, but there are only three recent records^1,2,3. (IUCN Red List).

CONSERVATION STATUS

Red List Category & Criteria: Amazona pretrei is listed as VU A2cd+3cd ver 3.1 (2001) (IUCN Red List).

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

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

Red List Evaluator: The Red List Evaluator for Amazona pretrei 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 : Amazona pretrei is listed by IUCN for the following: The combination of a comparison of population estimates in 1971 and 1997, and deforestation rates over the same period suggest that the species has declined rapidly at a rate greater than 30% in 10 years, which qualifies the species as Vulnerable. The ongoing threats of habitat loss and trapping suggest that this decline is likely to continue. (IUCN Red List).

Threats: 1.1.4.2 (Wikipedia).

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