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.

There is an excellent note by Ed Willis and Yoshika Oniki in The Wilson Bulletin, Vol. 93, No. 1, March 1981 .
