The species is found in Brazil, Colombia, Venezuela, and eastern French Guiana; also a small river region of northeast Bolivia.

Feeding Habits
Blackish-grey Antshrike's primary diet consists of a variety of insects and arthropods, including crickets, cockroaches, moths, caterpillars, stick-insects, bugs, beetles, and hymenopterans. They forage low to the ground, utilizing hops and short flights, with distinctive feeding behaviors such as reaching down to snatch prey or jumping to glean from leaf undersides. Unique adaptations include hanging from roots in mangrove forests to feed.
Habitat
Blackish-grey Antshrike thrives in the dense undergrowth of Amazonian habitats, including flooded evergreen and gallery forests, as well as savanna woodlands interspersed with shrubby vegetation. It is notably prevalent in river islands and riverine environments such as várzea and igapó forests, often occupying areas subjected to seasonal flooding. Coastal mangroves also provide suitable habitats, where blackish-grey Antshrike favors regions rich in both white and red mangrove species.

Distribution Area

The blackish-grey antshrike is found in Brazil's southeastern Amazon Basin as well as along the Amazon River proper, and northwards at the Amazon's outlet, into the extreme eastern areas of French Guiana with Brazil's northeast state of Amapá. The southeast range extends slightly southwestward into that quadrant, about 1000–1400 km, and its eastern limit is the final 950 km of the Tocantins River drainage. On the west bordering some of the southwest quadrant, the range is limited by the Madeira River and continues upstream into extreme northeast Bolivia for 75 km in an area around the Madeira and Guaporé River confluence. To the east the range is contiguous and covers the river drainages of the Tapajós, Xingu River, and lower Tocantins River, a range of about 3500 km. The northwest extension of the range expands from the Amazon River northwestwards upstream on the Rio Negro, (as a river corridor) into eastern and central Colombia, also eastward and north into central and southern Venezuela into the Orinoco River drainage. In the central Orinoco drainage, it does not range away from the river northwards, nor is it found in the lower third of the drainage to the Caribbean.
