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 →

Rare
Under 5% of wildlife watchers report an Epaulet Oriole sighting in Manu National Park on a given day, based on 122 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 343rd most-seen of the 641 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
January, April and August
In those months about 10% of wildlife watchers report an Epaulet Oriole in Manu National Park on a given day, against under 5% in February–March, May–July and September–December, the lowest months.
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.
13th of 18
Of the 18 parks where we can rate Epaulet Oriole sightings, Manu National Park ranks 13th at under 5%. The best odds are in El Impenetrable National Park (Argentina, about 50%), 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 Manu National Park (122 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.
