Taxonomy

Taxonomic note
Zosterops kulambangrae and Z. tetiparius were previously lumped as Z. kulambangrae (del Hoyo and Collar 2016), but are split on the basis of differences in vocalisations and deep genetic divergence (Manthey et al. 2020). This species and Rendova subspecies have often erroneously been listed under name rendovae, but see Z. rendovae. Monotypic.

Population justification: The population size of this species has not been quantified, but it is described as locally common to abundant (Dutson 2011, van Balen 2021).

Trend justification: Remote sensing data indicate that forest loss is ongoing within the range, occurring at a rate equivalent to c.11% within ten years (Global Forest Watch 2023, using data from Hansen et al. [2013] and methods disclosed therein). However, this species is found in all habitats including forest edge and gardens, and is equally abundant in primary forest and taller secondary growth (Dutson 2011, van Balen 2021). As such, the species may not be affected detrimentally by forest loss and is tentatively suspected to be stable.
