A large, uniformly plumaged Myrmeciza, the Immaculate Antbird generally sings from dense cover, and is therefore not necessarily easy to observe. Males are basically all black, with the exception of the dull blue orbital skin around the red irides, whilst females are essentially warm brown overall, becoming duskier over the face and throat, with a blackish tail, and share the bare surround to the eyes. The Immaculate Antbird ranges from Nicaragua south to Panama, thence through northern Colombia to northwest Venezuela, and south to western Ecuador. In terms of habitat, the species prefers the understory of humid evergreen forest, usually on hillsides, and frequently in areas where there are treefalls or natural light gaps; it has been recorded locally to 2300 m elevation. It has been suggested that the Immaculate Antbird’s closest relative is the Sooty Antbird (Myrmeciza fortis) of upper Amazonia, although this remains to be confirmed.
