The epaulet oriole (Icterus cayanensis) is a species of bird in the family Icteridae, the oropendolas, New World orioles, and New World blackbirds. It is found in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, Trinidad, and Venezuela.
The epaulet oriole was formally described in 1766 with the binomial Oriolus cayanensis. Since then it has a complicated taxonomic history. For much of the twentieth century some authors considered it and the moriche oriole (I. chrysocephalus) to be individual monotypic species. Other authors treated chrysocephalus as a subspecies of I. cayanensis. In the twenty-first century most taxonomic systems have adopted the latter position. 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 →

Likely
About 50% of wildlife watchers report an Epaulet Oriole sighting in El Impenetrable National Park on a given day, based on 186 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 22nd most-seen of the 219 birds we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
June–July and September–October
In those months about 60% of wildlife watchers report an Epaulet Oriole in El Impenetrable National Park on a given day, against about 30% in March, the lowest month. Those are among El Impenetrable National Park's driest months, with about 45 mm of rain a month against 120 mm in March. December has too few records to rate.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Epaulet Oriole sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 18 parks where we can rate Epaulet Oriole sightings, El Impenetrable National Park has the highest daily chance: about 50%. Next come El Palmar National Park (Argentina, about 50%) and Iberá National Park (Argentina, about 30%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Epaulet Oriole is recorded against all the birds logged in El Impenetrable National Park (186 verified sightings from 2019 to 2026), 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.
