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 →

GBIF citizen-science records
It is estimated from how often the Crested Oropendola is recorded against all the birds logged in Parque Estadual Encontro das Águas (733 verified sightings from 2019 to 2026), calibrated against known sighting rates.
