Schistocichla caurensis
This species is similar to the Spot-winged Antbird and the Roraiman Antbird (the latter is a recent split from the Spot-winged Antbird). At ca. 15 cm both are smaller than the Caura Antbird, which has a total length of ca. 19 cm. The male Caura Antbird is best separated from both species by its red eyes and all-dark bill (no pale lower mandible). It is also more uniform than the clearly two-toned male Spot-winged. The female Caura is potentially more confusing, but is generally darker below than female Spot-winged, has grey legs unlike female Spot-winged of the nominate subspecies (which has pinkish legs), and grey face-sides unlike female subspecies infuscata of the Spot-winged (which has has brownish-olive face-sides). Females of the Roraiman Antbird share the darker underparts, grey legs and face-sides, and are consequently best separated by their smaller size, proportionally smaller bill, and proportionally longer legs. The overlap in the range of these two species is marginal. All are easily separated by voice.
