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.

Possible
About 30% of wildlife watchers report a Streak-backed Oriole sighting in Santa Rosa National Park on a given day, based on 237 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 29th most-seen of the 233 birds we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
April
In that month about 50% of wildlife watchers report a Streak-backed Oriole in Santa Rosa National Park on a given day, against about 20% in September and November, the lowest months. That is one of Santa Rosa National Park's driest months, with about 35 mm of rain against 450 mm in October.
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.
3rd of 13
Of the 13 parks where we can rate Streak-backed Oriole sightings, Santa Rosa National Park ranks 3rd at about 30%. The best odds are in Las Baulas Marine National Park (Costa Rica, about 50%) and Cañón del Sumidero National Park (Mexico, about 40%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Streak-backed Oriole is recorded against all the birds logged in Santa Rosa National Park (237 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.
