The Slender Antbird is a Brazilian endemic found only in a few remnants of dry forest known as mata-de-cipó in the interior of south Bahia. It is found associated with large ground bromeliads of the genus Aechmea. The male in photo 1 is perched on an Aechmea bromeliad.

It is a large grey antbird and the male, shown in photos 1, 4, 5 and 6 has a triangular black throat patch, white wing-bars and a red iris. The female, shown in photos 2, 3, 7 and 8 is similar but with a rufous-brown crown and nape, a white throat and paler underparts turning to white in mid-belly.

The birds feed on the ground and in the bromeliads where they look for spiders, termites, grasshoppers and other invertebrates.
