The rufous-browed peppershrike (Cyclarhis gujanensis) is a passerine bird in the vireo family. It is widespread and often common in woodland, forest edge, and cultivation with some tall trees from Mexico and Trinidad south to Argentina and Uruguay.
The rufous-browed peppershrike was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it in the genus Tanagra and coined the binomial name Tanagra gujanensis. The specific epithet is derived from the type locality, the Guianas. Gmelin based his account on "Le verderoux" from French Guiana that had been described in 1778 by the French polymath Comte de Buffon in his multivolume Histoire Naturelle des Oiseaux. The rufous-browed peppershrike is now placed with the black-billed peppershrike in the genus Cyclarhis that was introduced in 1824 by William Swainson.

GBIF citizen-science records
It is estimated from how often the Rufous-browed Peppershrike is recorded against all the birds logged in Brasilia (469 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
