The chestnut-headed oropendola (Psarocolius wagleri) is a species of bird in the family Icteridae, the oropendolas, New World orioles, and New World blackbirds. It is found in Mexico, in every Central American country except El Salvador, and in Colombia and Ecuador.
The chestnut-headed oropendola was formally described in 1844 with an illustration and the binomial Cacicus Wagleri [sic]. Its specific epithet commemorates Johann Georg Wagler, who had erected genus Psarocolius in 1827. It eventually was reassigned to Psarocolius but for a time was placed in its own genus Zarhynchus.
Chestnut-headed oropendola males average 35 cm (14 in) long and females 28 cm (11 in). Males weigh an average of 214 g (7.5 oz) and females 113 g (4.0 oz).

Their body and wings are mostly black with a bluish gloss. Their rump and uppertail coverts are dark... Wikipedia →

With luck
About 10% of wildlife watchers report a Chestnut-headed Oropendola sighting in Chirripó National Park on a given day, based on 176 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 100th most-seen of the 332 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.

Across all the parks we cover, that three-hour window holds the most Chestnut-headed 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.

GBIF citizen-science records
It is estimated from how often the Chestnut-headed Oropendola is recorded against all the birds logged in Chirripó National Park (176 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.
