lone white-eye foraging above us in flowering bush at a road cut; we were uncertain of which white-eye occurs here, and that grew more complicated with eBird's 2021 taxonomic update a month after we returned home. Z. a. stierlingi appears to be the highland taxa in east Tanzania (Pale White-eye Z. flavilateralis is apparently the lowland white-eye in the thornscrub below the Rubehos; we could use more specific information). Photos. Further note: research reveals that Fjeldsa et al. (2010) Distribution of highland forest birds across a potential dispersal barrier in the Eastern Arc Mts of Tanzania, Steenstrupia 32: 1-43, reported that their extensive surveys, that included several locations in the Rubeho Mts., located only Zosterops senegalensis [called African Yellow White-eye at the time] in the forest from 1200-2290m. Subspecies stierlingi was then a race of senegalensis (e.g., Howard & Moore, 4th ed) and is now a race of anderssoni. This strongly supports our allocation of our lone white-eye to A. anderssoni. Our elevation in the forest at 1890m is within the elevational range of the species we have used here.
