The dusky-green oropendola is a species of bird in the family Icteridae. It is found on the eastern slope of the Andes in Bolivia and Peru. Its natural habitats are subtropical or tropical moist montane forests and heavily degraded former forest.
Region
Eastern Andes
Typical Environment
Occurs on the eastern (Amazon-facing) slopes of the Andes in southern Peru and western Bolivia, mainly within Yungas montane forests. It favors humid foothill to mid-elevation forest, including edges, clearings, and secondary growth, and can persist in partially degraded habitats. Typically uses the middle to upper canopy but will descend to fruiting trees along roadsides and ravines. Colonies often situate near watercourses or gaps where nest trees are prominent.
Altitude Range
600–2500 m
Climate Zone
Highland
Ease of Keeping
Beginner friendly: 1/5
This oropendola is a canopy-dwelling icterid of the Andean east slope, where it often joins fruiting flocks. Like its relatives, it weaves long, pendulous nests that hang in loose colonies high over clearings. Males perform dramatic bowing displays accompanied by bubbly, metallic notes. It helps disperse seeds and also consumes insects, making it ecologically important in montane forests.
Temperament
social and active
Flight Pattern
strong flier with direct, rapid wingbeats
Social Behavior
Often found in small groups or loose flocks, especially around fruiting trees. Breeds colonially, weaving long hanging nests from fibers suspended high in canopy trees. Males display at colony sites and may be polygynous, while females handle most incubation and chick-rearing.
Migratory Pattern
Resident
Song Description
Calls are a mix of bubbly, gurgling notes and metallic clanks, often delivered during bowing display postures. Vocalizations carry well through the forest and are used for colony communication. Contact calls are harsher and shorter when moving through canopy flocks.
