The streak-backed oriole (Icterus pustulatus) is a medium-sized species of passerine bird in the family Icteridae, the oropendolas, New World orioles, and New World blackbirds. It is found in Mexico, in Central America from Guatemala to Costa Rica, and occasionally in the United States.
The streak-backed oriole was formally described in 1829 with the binomial Psarocolius pustulatus. The streak-backed oriole's further taxonomy is unsettled. The IOC, AviList, and BirdLife International's Handbook of the Birds of the World (HBW) assign it these eight subspecies:

Rare
Under 5% of wildlife watchers report a Streak-backed Oriole sighting in El Triunfo on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 215th most-seen of the 221 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 to March
In those months about 10% of wildlife watchers report a Streak-backed Oriole in El Triunfo on a given day, against under 5% in April–May and July–December, the lowest months. Those are among El Triunfo's driest months, with about 20 mm of rain a month against 420 mm in June. June has too few records to rate.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Streak-backed Oriole sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
11th of 13
Of the 13 parks where we can rate Streak-backed Oriole sightings, El Triunfo ranks 11th at under 5%. The best odds are in Las Baulas Marine National Park (Costa Rica, about 50%), Cañón del Sumidero National Park (Mexico, about 40%) and Santa Rosa National Park (Costa Rica, about 30%). All parks ranked.
Same genus: Icterus
The closest relatives of the Streak-backed Oriole that you can see in El Triunfo (genus Icterus, New World Orioles) are Baltimore Oriole (about 30%), Altamira Oriole (about 20%) and Orchard Oriole (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Streak-backed Oriole is recorded against all the birds logged in El Triunfo (7 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.
