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.

With luck
About 10% of wildlife watchers report a Rufous-browed Peppershrike sighting in Manaus on a given day, based on 66 verified sightings from GBIF citizen-science data. It is the 28th most-seen of the 116 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
January–February and April–May
In those months about 20% of wildlife watchers report a Rufous-browed Peppershrike in Manaus on a given day, against under 5% in October, the lowest month. Those are among Manaus's wettest months, with about 230 mm of rain a month against 50 mm in August.
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.
18th of 35
Of the 35 cities where we can rate Rufous-browed Peppershrike sightings, Manaus ranks 18th at about 10%. The best odds are in Fortaleza (Brazil, about 50%), Brasilia (Brazil, about 50%) and Natal (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 Manaus (66 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.
