This recently split species has been classified as Near Threatened owing to concerns that its small population is declining moderately rapidly owing to on-going clearance of forest for shifting agriculture. It is not listed under a higher threat category because there is insufficient information about its sub-population structure.
Sphenocichla humei (Sibley and Monroe 1990, 1993) has been split into S. humei and S. roberti following Collar (2006).
Identification. 140-160 cm.
