See text Oropendolas are a genus of passerine birds, Psarocolius, in the New World blackbird family Icteridae.

All the oropendolas are large birds with pointed bills, and long tails which are always at least partially bright yellow.

The legs are dark, but the bill is usually a strikingly contrasting feature, either pale yellow, or red-tipped with a green or black base.

They are colonial breeders, with several long woven basket nests in a tree, each hanging from the end of a branch.

As can be observed from morphology, the band-tailed (Ocyalus latirostris) and the casqued oropendolas (Psarocolius oseryi) are the most distinct species.
