Mexico, Puerto Rico [int], United States [int] (IUCN Red List).

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

Major Habitat(s): 1.5 Forest - Subtropical/Tropical Dry
1.6 Forest - Subtropical/Tropical Moist
11.2 Artificial/Terrestrial - Pastureland (IUCN Red List).

Range: Amazona viridigenalis is locally and seasonally fairly common to common on the Atlantic slope of north-east Mexico⁵, mostly in Tamaulipas and San Luis Potos, with small colonies in extreme north-east Quertaro⁶. It formerly occurred in Nuevo Len and Veracruz, but there have been no records of wild birds since 1945 and 1960 respectively. In 1992-1994, densities in one area were estimated at 5.7 birds/km, indicating a wild population of 3,000-6,500 birds^2,4. This compares with 25.2 birds/km reported in the 1970s¹. The population recently established in urban areas of the Lower Rio Grande Valley (Texas), USA is considered by some to consist of wild birds⁹. Introduced or feral populations are also established (and mostly increasing) in Florida and California (USA), Puerto Rico (to USA), O'ahu (Hawaii) and several parts of Mexico³. (IUCN Red List).
