The chivi vireo (Vireo chivi) is a small South American songbird in the family Vireonidae. It was formerly considered as a subspecies of the red-eyed vireo. There are 9 subspecies of the chivi vireo. The vireo is usually green to yellow-green in color with off white underparts, and a gray crown. It has a whitish supercilium extending over its ear coverts, and its lores are dull gray in color. The majority of the bird's diet is composed of arthropods, although some subspecies eat fruit and some are also thought to be nectarivorous.
