However, as of late 2025 BirdLife International's Handbook of the Birds of the World (HBW) retains the two taxa as separate species.
In the mid-twentieth century one author placed the epaulet oriole and the orchard oriole (I. spurius) in a separate genus Bananivorus but later work showed... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Epaulet Oriole is recorded against all the birds logged in Rosario (42 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
