The Rufous-browed Peppershrike is one of the largest species of the vireo. It inhabits a wide range of open and semi-open habitats throughout tropical and subtropical Central and South America. It is perhaps hardest to see in Amazonia where it is restricted to floodplain forests and edges but becomes increasingly common, or at least easier to see, in more arid regions. The Rufous-browed Peppershrike is well known for its complex and extensive geographic variation, yet most subspecies are to some extent white below, olive above with rufous lores and supercilium. The song is equally as variable but is generally a series of rich musical phrases that is repeated seemingly without end.
