The Rusty-flanked Crake is endemic to Venezuela and is only known from perhaps a dozen localities along the Caribbean slope west of the Rio Orinoco. It is extremely poorly known but, with a better understanding of its vocalizations, has been found in an increasing number of localities. It is restricted to aquatic vegetation fringing marshes, lakesides, pools, flooded pastures and even dry grassland from sea level to 1400m. Though there is no data on foraging or general behavior but it is presumably like many of its congeners, foraging on the ground or in shallow water for insects. It is best located by voice and if seen, is distinctive, being the only crake with pure red-flanks in its range.
