Small, retiring quail of forest understory. Rarely seen, but can be located by listening for noisy rustling in the leaf litter as birds scratch like chickens. Prefers to run away rather than flush. Loud song often reveals its presence, given mainly early and late in the day: first few notes similar to Little Tinamou song, but then breaks into rollicking choruses that can be almost deafening if close by. Male has rusty face and gray body, female colors reversed, with gray face and rusty body.
