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.

Likely
About 50% of wildlife watchers report a Rufous-browed Peppershrike sighting in Natal on a given day, based on 46 verified sightings from GBIF citizen-science data. It is the 16th most-seen of the 50 birds we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
July
In that month about 60% of wildlife watchers report a Rufous-browed Peppershrike in Natal on a given day, against about 30% in April and November, the lowest months. That is one of Natal's wettest months, with about 150 mm of rain against 15 mm in November. January–February and June have too few records to rate.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Rufous-browed Peppershrike sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 35 cities where we can rate Rufous-browed Peppershrike sightings, Natal ranks 3rd at about 50%, level with the leaders once rounded. The best odds are in Fortaleza (Brazil, about 50%) and Brasilia (Brazil, about 50%).
GBIF citizen-science records
It is estimated from how often the Rufous-browed Peppershrike is recorded against all the birds logged in Natal (46 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.
