The crested oropendola also known as the Suriname crested oropendola or the cornbird (Psarocolius decumanus) is a New World tropical icterid bird. It is a resident breeder in lowland South America east of the Andes, from Panama and Colombia south to northern Argentina, as well as on Trinidad and Tobago. If the genus Gymnostinax for the Montezuma oropendola and its closest relatives were considered valid, this species would probably belong in that genus (Price & Lanyon 2002).
