The monochrome ant strangler ( Thamnophilus unicolor ), syn. Dysithamnus unicolor , belongs to the genus Thamnophilus within the ant bird family (Thamnophilidae) .

The species occurs in Ecuador , Colombia and Peru .

The range includes humid tropical or subtropical mountain forests and forest edges from 1200 to 2200 m altitude and is thus one of the few species of birds that have adapted to higher habitats .

The Latin additional species means monochrome.

The male has a pale iris , a black beak, is otherwise slate-gray with no special features, the head is slightly darker. Sometimes the outer control springs have small white tips.
