The green-backed becard (Pachyramphus viridis) is a species of passerine bird in the family Tityridae, the tityras, becards, and allies. It is found in Argentina, Bolivia, Brazil, Guyana, Paraguay, Uruguay, and Venezuela. The green-backed becard includes the yellow-cheeked becard as a subspecies.
The green-backed becard was formally described in 1816 by the French ornithologist Louis Vieillot under the binomial name Tityra viridis. He based his account on the "Caracterizados verde y corona negra" from Paraguay that had been described in 1805 by the Spanish naturalist Félix de Azara in his Apuntamientos para la historia natural de los páxaros del Paragüay y Rio de la Plata. The specific epithet viridis is Latin meaning "green". The green-backed becard is now one of 17 species placed in the genus Pachyramphus that was introduced in 1839 by the English zoologist George Robert Gray.
The genus has variously been assigned to the tyrant flycatcher family Tyrannidae, and the cotinga family Cotingidae. Several early twenty-first century studies confirmed the placement of Pachyramphus in Tityridae and taxonomic systems made the reassignment.

With luck
About 10% of wildlife watchers report a Green-backed Becard sighting in El Impenetrable National Park on a given day, based on 29 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 128th most-seen of the 219 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
September
In that month about 20% of wildlife watchers report a Green-backed Becard in El Impenetrable National Park on a given day, against about 10% in January–August and October–November, the lowest months. That is one of El Impenetrable National Park's driest months, with about 30 mm of rain against 120 mm in March. December has too few records to rate.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Green-backed Becard sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 10 parks where we can rate Green-backed Becard sightings, El Impenetrable National Park has the highest daily chance: about 10%. Next come El Palmar National Park (Argentina, about 10%) and Serra dos Órgãos National Park (Brazil, under 5%).
GBIF citizen-science records
It is estimated from how often the Green-backed Becard is recorded against all the birds logged in El Impenetrable National Park (29 verified sightings from 2019 to 2026), 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.
