Rather like the Gray-bellied Antbird (Myrmeciza pelzelni), which also occupies a similar, highly isolated, range at the border of three countries in the Negro–Orinoco drainage, much of our basic knowledge concerning the generally uncommon Yapacana Antbird has only been garnered very recently. This antbird, which is largely gray and whitish, with neat white wing-spots, in males, and gray and reddish brown in females, is seemingly restricted to stunted forest growing on white-sand soils, with abundant bamboo and sawgrass in the understory. The species occurs from eastern Colombia and southwest Venezuela south to far northwest Brazil, and has never been found above 150 m elevation. The Yapacana Antbird feeds on insects and spiders, which are sought either close to, or on, the ground, and does not join mixed-species flocks. Although its general behavior has now been reasonably well described, we still know virtually nothing concerning its breeding biology.
