The crested oropendola (Psarocolius decumanus), also known as the cornbird, is a species of bird in the family Icteridae, the oropendolas, New World orioles, and New World blackbirds. It is found in Costa Rica, Panama, Trinidad and Tobago, and every mainland South American country except Chile and Uruguay. It is "[u]ndoubtedly overall the commonest and most widespread oropendola".
The crested oropendola was formally described in 1769 with the binomial Xanthornis decumanus. Some authors placed it in genus Ostinops before it was assigned to its present Psarocolius. The crested oropendola's further taxonomy is unsettled. The IOC, the Clements taxonomy, and AviList assign it these four subspecies:
The Cornell Lab of Ornithology's Birds of the World states that DNA data do not support P. d. maculosus as a defined subspecies but does include its description and range in its species account... Wikipedia →

Possible
About 30% of wildlife watchers report a Crested Oropendola sighting in Henri Pittier National Park on a given day, based on 256 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 22nd most-seen of the 358 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 70% of wildlife watchers report a Crested Oropendola in Henri Pittier National Park on a given day, against about 10% in June and August–October, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Crested 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.
7th of 29
Of the 29 parks where we can rate Crested Oropendola sightings, Henri Pittier National Park ranks 7th at about 30%. The best odds are in Amboró National Park (Bolivia, about 80%), Main Ridge Forest Reserve (Trinidad and Tobago, about 50%) and Sierra de la Macarena National Park (Colombia, about 40%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Crested Oropendola is recorded against all the birds logged in Henri Pittier National Park (256 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.
