The Rufous-faced Crake is one of the most poorly known species in its genus and even family, in South America. It is only known from three small disjunct regions in Bolivia, central Paraguay and south central Brazil. In these three regions it inhabits coarse, tussocky or mated grass in moist areas of marshes. There is no recorded information on its diet or foraging behavior, though presumably similar to other members of its genus. Specimens have been captured in traps baited with peanut butter, oats, corn and banana. Though only known from four localities in the three regions mentioned previously, it undoubtedly occurs between these two regions and is likely more common than currently supposed and a limited understanding of its habitat preferences and vocalizations has hindered the discovery of additional localities.
