 The Bonin white-eye does show some changes in feeding niches in the presence of the warbling white-eye, feeding lower down in the canopy when the warbling white-eye is present, but its population, food selection, or the size of its chicks have not been affected.Juvenile Bonin white-eyes join warbling white-eyes and brown-eared bulbuls in mixed species feeding flocks in the non-breeding season.Brown-eared bulbuls may sometimes take Bonin white-eye eggs.
