This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Terpsiphone rufiventer (Sibley and Monroe 1990, 1993) was split into T. rufiventer and T. smithii following Harrison (1990) and this treatment followed by Collar et al. (1994) and BirdLife International (2000, 2004). However, the distinctiveness of smithi falls within the variation found within rufiventer, and this split is now not considered valid by the BirdLife Taxonomic Working Group.
