The black oropendola (Psarocolius guatimozinus) is a species of bird in the family Icteridae, the oropendolas, New World orioles, and New World blackbirds. It is found in Colombia and Panama.

The specific epithet guatimozinus derives from Guatemozin, who was a nephew of Montezuma and last Aztec emperor. Some early twentieth century authors placed the species in genus Gymnostinops, which was later merged into the current Psarocolius. Some authors have suggested that the black oropendola, the Baudo oropendola (P. cassini), and the olive oropendola (P. bifasciatus) should be merged as a single species.
The black oropendola is monotypic. Male black oropendolas are about 47 cm (19 in) long and females about 39 cm (15 in). Adult males have long black feathers on their nape that form a crest. Females have a shorter crest but are otherwise like males except for their smaller size. Adults are mostly black. They have a patch of bare pale blue skin on their face and a pink wattle at the base of the bill. Their scapulars, upperwing coverts, lower back, rump... Wikipedia →

Possible
About 20% of wildlife watchers report a Black Oropendola sighting in Darién National Park on a given day, based on 113 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 37th most-seen of the 397 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
March–April and December
In those months about 40% of wildlife watchers report a Black Oropendola in Darién National Park on a given day, against about 10% in January–February and July–November, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Black Oropendola sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Darién National Park, in our data
Darién National Park is the only park on Wallace's Line with enough records to rate Black Oropendola sightings: about 20% of wildlife watchers there report one on a given day.
Same genus: Psarocolius
The closest relatives of the Black Oropendola that you can see in Darién National Park (genus Psarocolius, Oropendolas) are Crested Oropendola (about 30%) and Chestnut-headed Oropendola (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Black Oropendola is recorded against all the birds logged in Darién National Park (113 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.
