The Black-throated Antshrike is a generally uncommon resident of the understory of lowland evergreen forest, below approximately 700 m, and is often found in densely vegetated areas such as around treefalls. It is endemic to the Guiana Shield, occurring from southeast Venezuela, across the Guianas, and over much of northeast Amazonian Brazil. Males are very dark birds with red eyes, being blackest over the crown throat, and breast, becoming slate-gray over the rest of the body and wings, while females are rufous-brown above and on the crown, with relatively densely dark-barred underparts and tail, and also have red eyes. Both sexes have a substantial, hook-tipped bill. The loudsong is a series of plaintive, downward-inflected whistles, which are relatively quiet. The Black-throated Antshrike forages low down, sometimes even on the ground itself, and the species has been recorded following army ant swarms.
