Subspecies
DNA data indicate that this species is closely related to Scott's Oriole (Icterus parisorum) and Audubon's Oriole (Icterus graduacauda). Hybridizes rarely with Yellow-tailed Oriole (Icterus mesomelas).
Proposed taxon hondae (based on two specimens from upper Magdalena Valley, in Colombia) appears undiagnosable and included within subspecies giraudii.
The following 4 subspecies are recognised:
mayensis van Rossem, 1938 - Northern Yucatán Peninsula (south-eastern Mexico).
chrysater (Lesson, 1844) - Central and southern Yucatán Peninsula (south to Belize) and southern Mexico (inland southern Veracruz, extreme eastern Oaxaca and Chiapas) south to northern Nicaragua.
giraudii Cassin, 1848 - Central Panama (on both coasts) to north-western Venezuela (Miranda), central and south-western Colombia and extreme north-western Ecuador (Esmeraldas).
