[8] They have also been observed in parks and botanical gardens in an urban metropolitan area in northern Colombia,[9] demonstrating their ability to succeed in certain anthropogenic environments.

[3] Olive-grey saltators are frugivorous birds, eating plant matter of all kinds.

They feed their chicks high-protein insects, and will occasionally consume them as adults in the dry season, when vegetation is scarcer.

[10] They have a preference for fruits and more tender vegetation (which contain more protein and nutrients),[10] particularly morning glory flowers,[4] but will consume mature leaves when other food is not readily available.

It was found that these birds spend little time foraging, and instead eat as much as they can and process it quickly, which allows them to get the necessary nutrients from foods that are high in fiber and otherwise difficult to digest.

[3] Not much is known about the nesting details of this species, but they appear to lay a clutch of 2-3 light-blue/turquoise eggs with black scrawls, which are smooth-shelled and oval-shaped.

[3] Listed as least concern by the IUCN,[7] olive-grey saltators are found throughout their range, common even in areas modified by humans.
