Green Oropendola (Psarocolius viridis) [XC260005]
by Peter Boesman from Orellana: 'Yuturi Lodge', s-bank R\u00edo Napo, Ecuador (subsong)
Green Oropendola (Psarocolius viridis) [XC521043]

Subspecies
No subspecies.
Analysis of mitochondrial DNA indicates present species is closer to Amazonian Oropendola (Psarocolius yuracares) than to Crested Oropendola (Psarocolius decumanus). Populations in north-eastern Peru sometimes separated as subspecies flavescens (described from Xeberos, in eastern Peru), but this separation seems unwarranted.
