The sharp calls and loud, raspy, accelerating song of the Dusky-throated Antshrike are some of the most characteristic sounds of understory mixed species flocks in Amazonia. Such flocks often include at least one member of the genus Thamnomanes, either the Dusky-throated or the very similar Saturnine (Thamnomanes saturninus) antshrike, which primarily forage in the understory. In some areas, a second species of Thamnomanes also may be present in the same flocks, either the Cinereous (Thamnomanes caesius) or Bluish-slate (Thamnomanes schistogynus) antshrike, which typically forage a little higher, into the forest midstory. All species in the genus perch with an upright posture, and sally for insect prey. The plumage in both sexes of Dusky-throated Antshrike is very nondescript. The male is almost entirely gray, although in many individuals there is a small patch of black on the throat (the dusky throat), while females are dull brown.
