This species qualifies as Critically Endangered because it appears to survive in tiny numbers at only one locality, where its habitat continues to be destroyed and degraded, such that its overall range and population are likely to be declining.
Zosterops atrifrons (Sibley and Monroe 1990, 1993) has been split into Z. atrifrons, Z. nehrkorni and Z. stalkeri following Rasmussen et al. (2000b).
