Possible
About 20% of wildlife watchers report a Chestnut-backed Antshrike sighting in Rio de Janeiro on a given day, based on 923 verified sightings from GBIF citizen-science data. It is the 34th most-seen of the 278 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
August–September and December
In those months about 30% of wildlife watchers report a Chestnut-backed Antshrike in Rio de Janeiro on a given day, against about 20% in January–July and October–November, the lowest months.

GBIF citizen-science records
It is estimated from how often the Chestnut-backed Antshrike is recorded against all the birds logged in Rio de Janeiro (923 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.
