A small member of the vireo family, the buff-cheeked greenlet is named for its warm buff facial wash contrasted with olive-green upperparts. It often travels with mixed-species flocks, gleaning insects from foliage in the midstory. Its cup-shaped nest is typically suspended from a forked twig, a hallmark of many vireonids. The species is widespread in northern Amazonia and the Guiana Shield and is not considered threatened.
