Audubon’s orioles (Icterus graduacauda) are year-round residents of southern Texas, eastern and southern Mexico, and the northern tip of Central America. In Mexico, the range splits into two allopatric regions: the eastern range extends from northeastern Mexico (Tamaulipas and Nuevo Leon) south to central Veracruz; the western range extends from central Nayarit south to Oaxaca. There are also a few populations in Belize.

Audubon’s orioles are further divided into four subspecies: I. graduacauda graduacauda, I. graduacauda audubonii, I. graduacauda nayaritensis and I. graduacauda dickeyae. The Atlantic range is occupied by overlapping populations of I. g. graduacauda and I. g. audubonii, while I. g. nayaritensis and I. g. dickeyae inhabit the western range. Range overlap is not observed between I. g. nayaritensis and I. g. dickeyae. The range of I. g. audubonii is confined to southern Texas, Tamaulipas, and Nuevo Leon, while I. g. graduacauda is found in the Mexican states of Veracruz and San Luis Potosí. Sightings of I. g. dickeyae have been documented in southern Mexico from Guerrero east to Oaxaca. The subspecies I. g. nayaritensis inhabits the western portions of Nayarit and northwestern Jacisco.
