The Olive Oropendola inhabits tall, humid terra firme forest (19, 121, 42, 68, 190), including open bamboo forests (146, 149, 191, 160). Additionally, it is found in nearby plantations (67), varzea forests (19, 3), wide riparian forests (184), transitional forests with secondary growth (161, 128, 42), and river islands (6, 73). It is also reported from white-sand forests in southern Venezuela (3, 43).

Altitudinally, it is mostly reported from locations below 700 m (2, 4), but in some areas it ranges into humid submontane forest. Across its range it has been report up to 200 m in Venezuela (3); mostly below 300 m, but locally to 600 m in Ecuador (34, 185); in Peru mostly below 500 m, but locally up to 1000 m (105, 187); locally to 900 m (5) or exceptionally, as high as 1200 m in Bolivia (2).

Despite the wide range of habitat types from whence this species is reported, the Olive Oropendola is generally considered to be a bird of more mature forests. As noted by Ridgely & Greenfield (34), it is frequently seen flying over nearly any Amazonian habitat type, but the widely sympatric Russet-backed Oropendola (Psarocolius angustifrons) seems to replace it for foraging and nesting in transitional, varzea, and river-edge forests (183, 2).
