The chivi vireo (Vireo chivi) is a small South American songbird in the family Vireonidae. It was formerly considered a subspecies of the red-eyed vireo. It 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 chivi vireo has nine subspecies. It is found throughout most of northern, eastern and central South America, only being absent from southern Chile and southern Argentina. It inhabits multiple types of habitat across its range, and appears to adjust well to slightly disturbed habitat. The chivi vireo is mainly resident, but at least two of the subspecies inhabiting the south of its range are known to be migratory.
The chivi vireo mates from May to June or October to January, depending on the region and subspecies. It makes cup nests and lay eggs in clutches of 2–4 which are incubated by the female, taking 10–16 days to hatch. Nestlings take 10–13 days to fully develop. The majority of the bird's diet is composed of arthropods, although some subspecies eat fruit and some are also thought to be nectarivorous.
