The specific epithet is from the Latin nigrescens "blackish" (from nigrescere "to become black"). The antbird was subsequently included in the genus Cercomacra but a molecular phylogenetic study published in 2014 found that Cercomacra was polyphyletic. The genus was split to create two monophyletic genera, and six species including the blackish antbird were moved to the newly erected genus Cercomacroides.
The blackish antbird has these five subspecies: What is now the riparian antbird (C. fuscicauda) was previously treated as a sixth subspecies of the blackish antbird but... Wikipedia →

Rare
Under 5% of wildlife watchers report a Blackish Antbird sighting in Podocarpus National Park on a given day, based on 13 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 348th most-seen of the 446 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Blackish Antbird in Podocarpus National Park on a given day, so our monthly data shows no clear season.
3rd of 4
Of the 4 parks where we can rate Blackish Antbird sightings, Podocarpus National Park ranks 3rd at under 5%. The best odds are in Manu National Park (Peru, about 10%) and Tambopata National Reserve (Peru, under 5%).
Same family: Thamnophilidae
The closest relatives of the Blackish Antbird that you can see in Podocarpus National Park (family Thamnophilidae, Typical Antbirds) are Plain Antvireo (about 10%) and Yellow-breasted Antwren (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Blackish Antbird is recorded against all the birds logged in Podocarpus National Park (13 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.
