Subspecies
Closely related to Moriche Oriole (Icterus chrysocephalus), and often treated as conspecific. Mitochondrial DNA data reveal small divergence (0·6%) between the two, and intermediate or hybrid individuals reported mostly from Suriname, but no known hybridization in areas of range overlap in Guyana and Brazil, nor in Sipaliwini area of central Suriname. Often treated as conspecific also with Variable Oriole (Icterus pyrrhopterus), but differs in larger size, more curved bill shape, habitat selection and behaviour. The two apparently occur sympatrically in a small area in Beni (Bolivia) without interbreeding.
The following 2 subspecies are recognised:
cayanensis (Linnaeus, 1766) - Northern, central.
chrysocephalus (Linnaeus, 1766) - Eastern Colombia to Venezuela, Guianas, northern Brazil and north-eastern Peru; Trinidad. Considered by some authors to be a distinct species, Moriche Oriole (Icterus chrysocephalus).
