Population justification: The global population size has not been quantified, but the species is described as common (Doughty et al. 1999). Analysis based on land cover data and a population density model estimated the population size of Rennell White-eye at around 11,700 mature individuals (Santini et al. 2019). Another estimate, based on the area of the species’s mapped range, the first quartile and median recorded population densities of other Zosterops species in Asia and the Pacific, and assuming that 13-45% of the range is occupied, the species’s population size is estimated to fall within the broad range 8,800 – 75,800 mature individuals.

Trend justification: The population is suspected to be in decline owing to ongoing habitat destruction and fragmentation. More evidence is needed to determine whether this qualifies as a continuing decline.
