Blackish antbird
The blackish antbird is a species of passerine bird in the family Thamnophilidae.
It is found in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Peru, and Suriname.
Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, and heavily degraded former forest.
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". 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.
There are five subspecies:
- C. n. nigrescens – Suriname, French Guiana and ne Brazil
- C. n. aequatorialis – south central Colombia, east Ecuador and northeast Peru
- C. n. notata – central Peru
- C. n. approximans – central Brazil
- C. n. ochrogyna Snethlage, E, 1928) – east central Brazil
