Distribution

Range in South America and Amazon Basin

The Black-fronted Nunbird is mostly found in the Amazon Basin south of the Amazon River; however it does occur in two river regions north, the first in the east between the confluence with the Xingu River westwards to the Tapajós River. The second region is at the confluence of the Rio Negro and upstream on the Amazon.

The species range expands eastward and southward beyond the Tocantins, of the Araguaia-Tocantins River system towards the region of the Cerrado of east-central Brazil; it is also in the Pantanal, but not the very southern portion.

The southwest and western regions of Black-fronted Nunbird's range occurs in Amazonian Bolivia, Peru, Ecuador, and southern Colombia, with the Amazonian Colombian region being the southwest portion of the entire northwestern Amazon region. The species' range is mostly contiguous; there are two localized populations in eastern coastal Brazil, the northern population in Alagoas state, and the southern locale in Rio de Janeiro state.
