Orange orioles (Icterus auratus) are endemic to the the Yucatan peninsula (Davis 1972; Howell and Webb 1995; Jaramillo and Burke 1999), including the Mexican states Quintana Roo, Campeche, and Yucatan as well as the northern tip of Belize. Considering the narrow range inhabited by this species, it is unsurprising that there does not appear to be any evidence of regional physical or behavioral variation.
