This species has a very 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). The population trend appears to be stable, and hence the species does not 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.
Bowie, R. C. K.; Fjeldså, J.; Hackett, S. J.; Crowe, T. M. 2004. Systematics and biogeography of Double-collared Sunbirds from the Eastern Arc Mountains, Tanzania. The Auk 121(3): 660-681.
Nectarinia mediocris (Sibley and Monroe 1990, 1993) has been split into N. mediocris and N. fuelleborni (including ssp. bensoni) following Bowie et al. (2004), but usumbarica is retained as a subspecies of N. mediocris contra Bowie et al. (2004). Morphological evidence in support of this treatment is equivocal but it is supported both phylogenetically and geographically with northern populations of N. m. mediocris and N. m. usumbarica separated from southern populations of N. f. fuelleborni and N. f. bensoni by N. loveridgei and N. moreaui.
