Population justification: The population size of this species has not been quantified, but it is described as fairly common (Eaton et al. 2021) and it is readily observed (eBird 2022).
Trend justification: In the ten years to 2022, forest loss on Ambon was c.1% (Global Forest Watch 2022, based on data from Hansen et al. [2013] and methods disclosed therein). Given this species' tolerance of some forest degradation (Eaton et al. 2021, eBird 2022), it is not thought that this level of habitat loss and degradation is likely to be impacting the species. Although its occurrence in the songbird trade cannot be ruled (especially owing to the fact out-of-range Zosterops in markets are notoriously difficult to identify), this species has not been recorded in market surveys (S. Brusland in litt. 2023) and, in absence of evidence to the contrary, trapping is not thought to be causing declines. In the absence of other threats, the population is considered stable.
