Conservation and Management

Conservation Status

Not globally threatened. Overall, the Olive Oropendola is fairly common in most of rather extensive range (198), but may be somewhat rare and local in some regions such as Venezuela and Ecuador (34, 3).

Effects of Human Activity

Although Olive Oropendola appears to forage in, and even nest in, edge and second-growth habitat, the proximity of tall, mature forest appears to be an important factor. (2). Felton et al. (145) found that Olive Oropendola was absent from forest from which wood was selectively harvested using reduced-impact logging techniques between one and four years previously. Subspecies yuracares is apparently viewed as a pest by fruit-growers in Bolivia (88), though the extent to which this may lead to its persecution has not been investigated.


The Olive Oropendola is offered some degree of protection in a variety reserves across its range, though most of these are within the range of the widely distributed yuracares subspecies. In general, the nominate race seems to be the least protected, though would be protected if the proposed Gurupí Biological Reserve becomes properly established (180). The following list names a few reserves from whence Olive Oropendola has been reported.
