 Introduced plants fed on include bananas, papaya, "Lantana", "Cucurbita moschata" (or squash) and "Calophyllum inophyllum".The Bonin white-eye does take some nectar but the extent to which it is an important food is unknown; observations on Hahajima showed it fed from flowers far less frequently than the warbling white-eye.In addition to plant food, insect and other invertebrate prey is taken as well.
