Medium-sized guan with a long tail. Note the whitish eyebrow. Dark brown above and chestnut below. Favors woodlands with wet areas and gallery forests, both rich in woody lianas. Normally feeds in the canopy, but may also descend to the ground. In alarm gives a raucous barking call, similar to other guans. Less common than the similar Rusty-margined Guan; Chestnut-bellied has more prominent pale eyebrow and white-streaked back.
