The blackish antbird was described by the German ornithologists Jean Cabanis and Ferdinand Heine in 1860 and given the binomial name Percnostola nigrescens. 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 Yasuní National Park on a given day, based on 25 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 452nd most-seen of the 533 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 Yasuní National Park on a given day, so our monthly data shows no clear season.
4th of 4
Of the 4 parks where we can rate Blackish Antbird sightings, Yasuní National Park ranks 4th at under 5%. The best odds are in Manu National Park (Peru, about 10%), Tambopata National Reserve (Peru, under 5%) and Podocarpus National Park (Ecuador, under 5%).
GBIF citizen-science records
It is estimated from how often the Blackish Antbird is recorded against all the birds logged in Yasuní National Park (25 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.
